      <title>How I built a Reddit lead finder with RSS, an LLM scorer and a Node worker</title>

      <guid>https://dev.to/matek075/how-i-built-a-reddit-lead-finder-with-rss-an-llm-scorer-and-a-node-worker-2ana</guid>
      <description>&lt;p&gt;Every time I shipped a side project, I lost evenings doing the same thing: searching Reddit for posts like "is there a tool that does X?" or "any alternative to Y?". Those posts are some of the warmest early leads a solo founder can get, but they are scattered across dozens of subreddits and fall off "new" within hours.&lt;/p&gt;

&lt;p&gt;So I built a small system to do the finding for me. This post is about how it's put together, what broke along the way, and what it still can't do. No growth hacks, just architecture.&lt;/p&gt;

&lt;h2&gt;
  
  
  The shape of the system
&lt;/h2&gt;

&lt;p&gt;There are two deploys and one database:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;strong&gt;A Next.js app&lt;/strong&gt; (App Router, Next 16, React 19) for the marketing site, the dashboard, billing and auth. Auth is Auth.js v5 with Google sign-in and email magic links.&lt;/li&gt;
&lt;li&gt;
&lt;strong&gt;A Node worker&lt;/strong&gt; (plain ESM, no framework) running on a separate VPS under PM2. It's actually two processes: a keyword worker that does the polling and scoring, and a small HTTP search API the app calls for on-demand searches and validation.&lt;/li&gt;
&lt;li&gt;
&lt;strong&gt;MongoDB&lt;/strong&gt;, shared by both.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;The app never talks to Reddit directly. The dashboard writes workspaces (a product description, subreddits, keywords) to Mongo; the worker reads them, fetches posts, stores matches and scores them; the dashboard reads matches back. When the app needs something right now (validating a subreddit, triggering a backfill for a new workspace), it calls the worker's search API with a shared secret header.&lt;/p&gt;

&lt;p&gt;Why split it? Next.js on a container is great at serving requests and terrible at long-running loops. Keeping the loops in a separate process means a deploy of the web app never interrupts a polling cycle, and a stuck Reddit request never ties up a web worker.&lt;/p&gt;

&lt;h2&gt;
  
  
  Reading Reddit: RSS, not JSON
&lt;/h2&gt;

&lt;p&gt;The obvious route is Reddit's &lt;code&gt;.json&lt;/code&gt; listings. In my setup those got 403s once traffic went through proxies, so the worker reads the public Atom feeds instead:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;code&gt;/r/{subreddit}/new/.rss&lt;/code&gt; for each watched subreddit&lt;/li&gt;
&lt;li&gt;search &lt;code&gt;.rss&lt;/code&gt; for keyword sweeps across Reddit&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;RSS gives you less than JSON (no scores, no comment counts), but for "has someone just asked for a thing like mine?" you mostly need title, body, author, link and timestamp, and Atom has all of those.&lt;/p&gt;

&lt;p&gt;Requests go out through a proxy pool with a configurable number of "lanes", a minimum gap between requests and a bounded retry count on 403s. All of that is configured through env variables, which brings me to the first lesson.&lt;/p&gt;

&lt;h2&gt;
  
  
  The worker loops
&lt;/h2&gt;

&lt;p&gt;&lt;code&gt;worker/index.js&lt;/code&gt; is basically a handful of timers:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;strong&gt;Poll&lt;/strong&gt; every 30 minutes (configurable): fetch &lt;code&gt;new&lt;/code&gt; for all watched subreddits, match against keywords, store new matches.&lt;/li&gt;
&lt;li&gt;
&lt;strong&gt;Search sweep&lt;/strong&gt; every 6 hours: keyword searches across Reddit to catch posts outside the watched subreddits.&lt;/li&gt;
&lt;li&gt;
&lt;strong&gt;Scoring&lt;/strong&gt; every 5 minutes: pick up unscored matches and send them to the LLM.&lt;/li&gt;
&lt;li&gt;
&lt;strong&gt;Backfill check&lt;/strong&gt; every 30 seconds: when a user creates a workspace, they shouldn't stare at an empty dashboard for half an hour, so a backfill job pulls recent history (using a web search API) and seeds matches.&lt;/li&gt;
&lt;li&gt;
&lt;strong&gt;Cleanup&lt;/strong&gt; every 24 hours, behind an explicit disable flag.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Splitting fetching from scoring was one of the better decisions. Fetching is cheap and bursty; scoring costs money and has rate limits. With separate loops, a slow LLM call never delays the next poll, and a Reddit outage never leaves the scorer idle with a backlog it can't reach.&lt;/p&gt;

&lt;h2&gt;
  
  
  Scoring with an LLM
&lt;/h2&gt;

&lt;p&gt;Keyword matching alone is noisy. "Looking for a CRM" matches a buyer, but so does "I hate every CRM I've tried, rant incoming" and "I built a CRM, roast it". The scorer sends each match plus the workspace's product description to an OpenAI model and asks how likely it is that this post is someone looking for a solution like this product.&lt;/p&gt;

&lt;p&gt;The interesting part isn't the prompt, it's the guardrails around it:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;strong&gt;Hard caps everywhere.&lt;/strong&gt; Max LLM calls per day globally, max scoring per user per day, a limit on how many items go through the first pass. A bug in a loop with an LLM call inside is a bug with a credit card attached.&lt;/li&gt;
&lt;li&gt;
&lt;strong&gt;Daily lead limits and alert thresholds.&lt;/strong&gt; If a cycle produces way more matches than usual, that's usually a broken filter, not a sudden market, and I'd rather get a Discord alert than a thousand junk "leads".&lt;/li&gt;
&lt;li&gt;
&lt;strong&gt;Regression fixtures.&lt;/strong&gt; There is a &lt;code&gt;lead-quality.json&lt;/code&gt; fixture of real-world-style posts with expected outcomes, and every matching bug fix adds a case. It's the closest thing to a test suite for "is the filter still sane?".&lt;/li&gt;
&lt;/ul&gt;

&lt;h2&gt;
  
  
  Replies: drafted, never posted
&lt;/h2&gt;

&lt;p&gt;For a lead worth answering, the app drafts a reply. The user edits it and posts it themselves. The tool never posts to Reddit on anyone's behalf.&lt;/p&gt;

&lt;p&gt;That's a product decision, not a technical limitation. Reddit communities are very quick to spot bots, and I didn't want to build a spam machine that gets its users banned. Drafting saves time; posting stays human.&lt;/p&gt;

&lt;h2&gt;
  
  
  Lessons learned
&lt;/h2&gt;

&lt;p&gt;&lt;strong&gt;1. Read env at call time, not at import.&lt;/strong&gt; The worker is ESM, and imports are evaluated before the body of the entry file. If a module reads &lt;code&gt;process.env.SOMETHING&lt;/code&gt; at the top level, it can run before the &lt;code&gt;.env.local&lt;/code&gt; loader does, and you get &lt;code&gt;undefined&lt;/code&gt; in production but not on your laptop. Now the env loader is the very first import, and modules read config inside functions (&lt;code&gt;getWebshareKey()&lt;/code&gt;, &lt;code&gt;pollExcludeUserIds()&lt;/code&gt;), with a test that fails if a value gets captured at import time.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;2. Duplicated schemas will bite you.&lt;/strong&gt; The app and the worker each have their own Mongoose schemas for the same collections. It keeps the worker deployable without the app's code, but every field change has to be made twice. I've left myself a loud note about it; a shared package would be the real fix.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;3. Anything that deletes data gets a kill switch.&lt;/strong&gt; The cleanup job exports old matches and then deletes them. It ships with a disable flag and refuses to delete if email isn't configured (so the export can't silently fail first). Boring, and exactly what you want at 2am.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;4. Make one command the definition of "done".&lt;/strong&gt; &lt;code&gt;npm run verify&lt;/code&gt; runs a syntax check, the worker tests (including the lead-quality fixture and a mocked backfill pipeline test), &lt;code&gt;next build&lt;/code&gt; and Playwright end-to-end tests. CI runs the same command on every PR. Solo projects need this more than team ones, because nobody else is going to catch it.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;5. Build the web app as an image, not on the server.&lt;/strong&gt; GitHub Actions builds a Docker image (Next &lt;code&gt;standalone&lt;/code&gt; output, Node 22 Alpine, non-root) and the host just pulls it. One gotcha: &lt;code&gt;NEXT_PUBLIC_*&lt;/code&gt; variables get inlined at build time, so changing them in the hosting dashboard does nothing until you rebuild.&lt;/p&gt;

&lt;h2&gt;
  
  
  Limitations (honestly)
&lt;/h2&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;strong&gt;30-minute polling isn't real-time.&lt;/strong&gt; On fast subreddits, someone may answer before you see the post. You can poll more often, but you pay for it in proxy traffic and rate limits.&lt;/li&gt;
&lt;li&gt;
&lt;strong&gt;RSS is a thin view of Reddit.&lt;/strong&gt; No vote counts, no comment trees, and feeds only show recent items, so if the worker is down for long, it misses things that backfill has to recover.&lt;/li&gt;
&lt;li&gt;
&lt;strong&gt;The LLM is a ranking aid, not an oracle.&lt;/strong&gt; It's good at pushing "is there a tool for…" above rants and launches. It still produces false positives, and the product description you give it matters a lot.&lt;/li&gt;
&lt;li&gt;
&lt;strong&gt;Dependence on Reddit's public endpoints.&lt;/strong&gt; If those change, the fetch layer changes with them.&lt;/li&gt;
&lt;/ul&gt;

&lt;h2&gt;
  
  
  Wrapping up
&lt;/h2&gt;

&lt;p&gt;If you want to build something similar, the core is small: an RSS fetcher, a keyword matcher, a queue of unscored items and an LLM call with strict caps. The rest is making it boring and reliable.&lt;/p&gt;

&lt;p&gt;I turned this into a product called &lt;a href="https://indiepilot.app" rel="noopener noreferrer"&gt;IndiePilot&lt;/a&gt; (there's a free plan) for founders who'd rather not run the plumbing themselves. Either way, I'm happy to answer questions about the architecture in the comments: what would you do differently?&lt;/p&gt;

      <title>Introducing FinanceFolio: Your Free Solution for Asset Management and Portfolio Tracking</title>
      <dc:creator>Matek</dc:creator>
      <pubDate>Mon, 04 Nov 2024 08:07:37 +0000</pubDate>
      <link>https://dev.to/matek075/introducing-financefolio-your-free-solution-for-asset-management-and-portfolio-tracking-3038</link>
      <guid>https://dev.to/matek075/introducing-financefolio-your-free-solution-for-asset-management-and-portfolio-tracking-3038</guid>
      <description>&lt;h2&gt;
  
  
  Introduction
&lt;/h2&gt;

&lt;p&gt;Managing your assets and tracking your portfolio's performance over time shouldn't be a complicated or costly endeavor. That's why I created FinanceFolio — a 100% free, ad-free SaaS application designed to simplify asset management and help you monitor how your portfolio evolves.&lt;/p&gt;

&lt;h2&gt;
  
  
  Key Features
&lt;/h2&gt;

&lt;p&gt;FinanceFolio consists of four main widgets — two editable and two chart-based — each tailored to give you comprehensive insights into your financial standing.&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;&lt;p&gt;Customizable Asset Groups: Categorize your assets into predefined groups like cash, real estate, precious metals, and stocks.&lt;br&gt;
Non-standard Investments: Have unique investments? No problem! You can add custom asset names to track any type of investment you hold.&lt;br&gt;
Value Tracking: Input and save the values of your assets to keep an up-to-date record.&lt;br&gt;
Portfolio Value Tracking Widgets&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Flexible Intervals: Monitor your portfolio's performance on a monthly or yearly basis.&lt;br&gt;
Growth/Decline Input: Record how much your portfolio has increased or decreased each month or year.&lt;br&gt;
Visual Charts: Get visual representations of your portfolio's trajectory to make informed decisions.&lt;/p&gt;&lt;/li&gt;
&lt;/ul&gt;

&lt;h2&gt;
  
  
  100% Free and Ad-Free
&lt;/h2&gt;

&lt;p&gt;FinanceFolio is completely &lt;strong&gt;free&lt;/strong&gt; to use. There are no hidden fees, premium tiers, or annoying advertisements. My goal is to provide a straightforward tool that empowers you to take control of your financial future without any barriers.&lt;/p&gt;

&lt;h2&gt;
  
  
  Technology Stack
&lt;/h2&gt;

&lt;p&gt;While I built FinanceFolio using React, TypeScript, i18next, and Firebase, it's important to note that the choice of technology is secondary to the value the application provides. When creating a startup, delivering a functional and reliable solution is paramount because clients care about results, not the underlying tech stack.&lt;/p&gt;

&lt;p&gt;Try it now -&amp;gt; &lt;a href="//financefolio.pl"&gt;Financefolio&lt;/a&gt;&lt;/p&gt;

      <title>Exploring the Latest Features in React and TypeScript</title>
      <dc:creator>Matek</dc:creator>
      <pubDate>Thu, 15 Feb 2024 11:58:41 +0000</pubDate>
      <link>https://dev.to/matek075/exploring-the-latest-features-in-react-and-typescript-272f</link>
      <guid>https://dev.to/matek075/exploring-the-latest-features-in-react-and-typescript-272f</guid>
      <description>&lt;p&gt;&lt;strong&gt;- TypeScript: Elevating Type Safety&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;TypeScript continues to push the boundaries of type safety with its latest features, making the developer's life easier by catching more errors at compile time.&lt;/p&gt;

&lt;p&gt;Stricter Type Checks for Tuples&lt;br&gt;
TypeScript's tuple types now support stricter type checks, ensuring that each element in a tuple array matches its specified type exactly. This feature is particularly useful when dealing with fixed-size arrays where the type and order of elements are critical.&lt;br&gt;
&lt;/p&gt;

&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight typescript"&gt;&lt;code&gt;&lt;span class="kd"&gt;let&lt;/span&gt; &lt;span class="nx"&gt;user&lt;/span&gt;&lt;span class="p"&gt;:&lt;/span&gt; &lt;span class="p"&gt;[&lt;/span&gt;&lt;span class="kr"&gt;string&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="kr"&gt;number&lt;/span&gt;&lt;span class="p"&gt;]&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="p"&gt;[&lt;/span&gt;&lt;span class="dl"&gt;'&lt;/span&gt;&lt;span class="s1"&gt;John Doe&lt;/span&gt;&lt;span class="dl"&gt;'&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="mi"&gt;42&lt;/span&gt;&lt;span class="p"&gt;];&lt;/span&gt; &lt;span class="c1"&gt;// OK&lt;/span&gt;
&lt;span class="nx"&gt;user&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="p"&gt;[&lt;/span&gt;&lt;span class="mi"&gt;42&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="dl"&gt;'&lt;/span&gt;&lt;span class="s1"&gt;John Doe&lt;/span&gt;&lt;span class="dl"&gt;'&lt;/span&gt;&lt;span class="p"&gt;];&lt;/span&gt; &lt;span class="c1"&gt;// Error: Type 'number' is not assignable to type 'string'.&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;



&lt;p&gt;This update enhances type safety and accuracy, especially when tuples are used to represent data structures with a fixed sequence of elements.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;- Leveraging React Server Components for Enhanced Performance and Efficiency&lt;/strong&gt;&lt;br&gt;
React's continuous evolution has brought us another groundbreaking feature: Server Components. This innovative approach enables developers to render components on the server, significantly reducing the amount of code shipped to the client, improving load times, and enhancing overall application performance. &lt;/p&gt;

&lt;p&gt;Key Benefits:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;&lt;p&gt;Reduced Bundle Size:&lt;br&gt;
Since Server Components are rendered on the server, the code for these components does not need to be included in the bundle sent to the browser.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Direct Access to Server-Side Resources:&lt;br&gt;
Server Components can directly query your database or access other server-side resources without the need for API calls from the client.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Improved Performance:&lt;br&gt;
By offloading work to the server and sending only the necessary HTML and JSON to the client, applications can load faster and feel more responsive.&lt;/p&gt;&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Using Server Components involves marking your React components as server-side by using the .server.js extension for their files. Here's a simple example to illustrate how you might use a Server Component in a React application.&lt;/p&gt;

&lt;p&gt;Let's say you have a component that fetches a list of users from your database. By making this a Server Component, you can directly execute the database query without exposing your database credentials to the client or relying on an additional API endpoint.&lt;/p&gt;

&lt;p&gt;Example: Fetching Data with a Server Component&lt;br&gt;
&lt;/p&gt;

&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight javascript"&gt;&lt;code&gt;&lt;span class="c1"&gt;// UsersList.server.js&lt;/span&gt;
&lt;span class="k"&gt;import&lt;/span&gt; &lt;span class="nx"&gt;React&lt;/span&gt; &lt;span class="k"&gt;from&lt;/span&gt; &lt;span class="dl"&gt;'&lt;/span&gt;&lt;span class="s1"&gt;react&lt;/span&gt;&lt;span class="dl"&gt;'&lt;/span&gt;&lt;span class="p"&gt;;&lt;/span&gt;
&lt;span class="k"&gt;import&lt;/span&gt; &lt;span class="p"&gt;{&lt;/span&gt; &lt;span class="nx"&gt;db&lt;/span&gt; &lt;span class="p"&gt;}&lt;/span&gt; &lt;span class="k"&gt;from&lt;/span&gt; &lt;span class="dl"&gt;'&lt;/span&gt;&lt;span class="s1"&gt;./database&lt;/span&gt;&lt;span class="dl"&gt;'&lt;/span&gt;&lt;span class="p"&gt;;&lt;/span&gt;

&lt;span class="k"&gt;export&lt;/span&gt; &lt;span class="k"&gt;default&lt;/span&gt; &lt;span class="kd"&gt;function&lt;/span&gt; &lt;span class="nf"&gt;UsersList&lt;/span&gt;&lt;span class="p"&gt;()&lt;/span&gt; &lt;span class="p"&gt;{&lt;/span&gt;
  &lt;span class="kd"&gt;const&lt;/span&gt; &lt;span class="nx"&gt;users&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="nx"&gt;db&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nf"&gt;query&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="dl"&gt;'&lt;/span&gt;&lt;span class="s1"&gt;SELECT * FROM users&lt;/span&gt;&lt;span class="dl"&gt;'&lt;/span&gt;&lt;span class="p"&gt;);&lt;/span&gt;

  &lt;span class="k"&gt;return &lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;
    &lt;span class="o"&gt;&amp;lt;&lt;/span&gt;&lt;span class="nx"&gt;ul&lt;/span&gt;&lt;span class="o"&gt;&amp;gt;&lt;/span&gt;
      &lt;span class="p"&gt;{&lt;/span&gt;&lt;span class="nx"&gt;users&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nf"&gt;map&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="nx"&gt;user&lt;/span&gt; &lt;span class="o"&gt;=&amp;gt;&lt;/span&gt; &lt;span class="p"&gt;(&lt;/span&gt;
        &lt;span class="o"&gt;&amp;lt;&lt;/span&gt;&lt;span class="nx"&gt;li&lt;/span&gt; &lt;span class="nx"&gt;key&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="p"&gt;{&lt;/span&gt;&lt;span class="nx"&gt;user&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nx"&gt;id&lt;/span&gt;&lt;span class="p"&gt;}&lt;/span&gt;&lt;span class="o"&gt;&amp;gt;&lt;/span&gt;&lt;span class="p"&gt;{&lt;/span&gt;&lt;span class="nx"&gt;user&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nx"&gt;name&lt;/span&gt;&lt;span class="p"&gt;}&lt;/span&gt;&lt;span class="o"&gt;&amp;lt;&lt;/span&gt;&lt;span class="sr"&gt;/li&lt;/span&gt;&lt;span class="err"&gt;&amp;gt;
&lt;/span&gt;      &lt;span class="p"&gt;))}&lt;/span&gt;
    &lt;span class="o"&gt;&amp;lt;&lt;/span&gt;&lt;span class="sr"&gt;/ul&lt;/span&gt;&lt;span class="err"&gt;&amp;gt;
&lt;/span&gt;  &lt;span class="p"&gt;);&lt;/span&gt;
&lt;span class="p"&gt;}&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;

  Embracing the AI Revolution: A Glimpse into Tomorrow
&lt;/h2&gt;

&lt;p&gt;The world as we know it is on the brink of a technological transformation, spearheaded by Artificial Intelligence (AI). This post explores how AI is not just a buzzword in tech industries but a rapidly evolving force transforming our daily lives.&lt;/p&gt;

&lt;h3&gt;
  
  
  AI in the Home: The Smart Living
&lt;/h3&gt;

&lt;p&gt;Imagine waking up to a home that knows your routine. Smart homes, powered by AI, are turning this into a reality. From intelligent thermostats that adjust the temperature based on your preferences and schedule to smart refrigerators that remind you to restock on groceries, AI is making homes more efficient and personalized. Voice assistants like Alexa and Google Assistant are becoming the central hubs of these smart homes, allowing you to control various aspects of your home with just your voice.&lt;/p&gt;

&lt;h3&gt;
  
  
  The Road Ahead: Autonomous Vehicles
&lt;/h3&gt;

&lt;p&gt;&lt;a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F8jk55bwxjsq5u2dr1nc7.png" class="article-body-image-wrapper"&gt;&lt;img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F8jk55bwxjsq5u2dr1nc7.png" alt="Image description" width="800" height="800"&gt;&lt;/a&gt;&lt;br&gt;

      <title>Introduction to Immer.js</title>
      <dc:creator>Matek</dc:creator>
      <pubDate>Fri, 20 Oct 2023 08:53:04 +0000</pubDate>

      <description>&lt;h3&gt;
  
  
  What is Immer.js?
&lt;/h3&gt;

&lt;p&gt;&lt;a href="https://immerjs.github.io/immer/" rel="noopener noreferrer"&gt;Immer.js&lt;/a&gt; is a library that provides a simple and intuitive API for working with immutable data in JavaScript applications. It is widely used in conjunction with state management libraries like Redux or Mobx. Immer.js allows developers to create a draft of the state that can be modified directly, and it takes care of producing a new immutable state with the changes applied.&lt;/p&gt;

&lt;h3&gt;
  
  
  Key Features
&lt;/h3&gt;

&lt;p&gt;Immer.js offers several notable features:&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Immutability Made Easy&lt;/strong&gt;: Immer.js simplifies the process of working with immutable data. Developers can directly modify the state as if it were mutable, and Immer.js takes care of producing a new immutable state.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Automatic Cloning&lt;/strong&gt;: The library automatically creates a new state tree by applying the changes, ensuring that the original state remains unaltered.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Efficient Updates&lt;/strong&gt;: Immer.js is designed to be highly efficient. It minimizes the amount of data copied during updates, making it suitable for handling large, complex state trees.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;React Integration&lt;/strong&gt;: Immer.js seamlessly integrates with React and is widely used with libraries like Redux, making it a go-to choice for state management in React applications.&lt;/p&gt;&lt;/li&gt;
&lt;/ol&gt;

&lt;h3&gt;
  
  
  Code Examples
&lt;/h3&gt;

&lt;p&gt;Let's look at some code examples to understand how Immer.js works. We'll use a simple example of a counter in a Redux-like store.&lt;br&gt;
&lt;/p&gt;

&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight javascript"&gt;&lt;code&gt;&lt;span class="k"&gt;import&lt;/span&gt; &lt;span class="nx"&gt;produce&lt;/span&gt; &lt;span class="k"&gt;from&lt;/span&gt; &lt;span class="dl"&gt;'&lt;/span&gt;&lt;span class="s1"&gt;immer&lt;/span&gt;&lt;span class="dl"&gt;'&lt;/span&gt;&lt;span class="p"&gt;;&lt;/span&gt;

&lt;span class="kd"&gt;const&lt;/span&gt; &lt;span class="nx"&gt;initialState&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="p"&gt;{&lt;/span&gt; &lt;span class="na"&gt;count&lt;/span&gt;&lt;span class="p"&gt;:&lt;/span&gt; &lt;span class="mi"&gt;0&lt;/span&gt; &lt;span class="p"&gt;};&lt;/span&gt;

&lt;span class="kd"&gt;const&lt;/span&gt; &lt;span class="nx"&gt;reducer&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="nx"&gt;state&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="nx"&gt;action&lt;/span&gt;&lt;span class="p"&gt;)&lt;/span&gt; &lt;span class="o"&gt;=&amp;gt;&lt;/span&gt; &lt;span class="p"&gt;{&lt;/span&gt;
  &lt;span class="k"&gt;return&lt;/span&gt; &lt;span class="nf"&gt;produce&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="nx"&gt;state&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="nx"&gt;draftState&lt;/span&gt;&lt;span class="p"&gt;)&lt;/span&gt; &lt;span class="o"&gt;=&amp;gt;&lt;/span&gt; &lt;span class="p"&gt;{&lt;/span&gt;
    &lt;span class="k"&gt;switch &lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="nx"&gt;action&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nx"&gt;type&lt;/span&gt;&lt;span class="p"&gt;)&lt;/span&gt; &lt;span class="p"&gt;{&lt;/span&gt;
      &lt;span class="k"&gt;case&lt;/span&gt; &lt;span class="dl"&gt;'&lt;/span&gt;&lt;span class="s1"&gt;INCREMENT&lt;/span&gt;&lt;span class="dl"&gt;'&lt;/span&gt;&lt;span class="p"&gt;:&lt;/span&gt;
        &lt;span class="nx"&gt;draftState&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nx"&gt;count&lt;/span&gt; &lt;span class="o"&gt;+=&lt;/span&gt; &lt;span class="mi"&gt;1&lt;/span&gt;&lt;span class="p"&gt;;&lt;/span&gt;
        &lt;span class="k"&gt;break&lt;/span&gt;&lt;span class="p"&gt;;&lt;/span&gt;
      &lt;span class="k"&gt;case&lt;/span&gt; &lt;span class="dl"&gt;'&lt;/span&gt;&lt;span class="s1"&gt;DECREMENT&lt;/span&gt;&lt;span class="dl"&gt;'&lt;/span&gt;&lt;span class="p"&gt;:&lt;/span&gt;
        &lt;span class="nx"&gt;draftState&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nx"&gt;count&lt;/span&gt; &lt;span class="o"&gt;-=&lt;/span&gt; &lt;span class="mi"&gt;1&lt;/span&gt;&lt;span class="p"&gt;;&lt;/span&gt;
        &lt;span class="k"&gt;break&lt;/span&gt;&lt;span class="p"&gt;;&lt;/span&gt;
      &lt;span class="nl"&gt;default&lt;/span&gt;&lt;span class="p"&gt;:&lt;/span&gt;
        &lt;span class="k"&gt;return&lt;/span&gt; &lt;span class="nx"&gt;draftState&lt;/span&gt;&lt;span class="p"&gt;;&lt;/span&gt;
    &lt;span class="p"&gt;}&lt;/span&gt;
  &lt;span class="p"&gt;});&lt;/span&gt;
&lt;span class="p"&gt;};&lt;/span&gt;

&lt;span class="c1"&gt;// Usage&lt;/span&gt;
&lt;span class="kd"&gt;let&lt;/span&gt; &lt;span class="nx"&gt;state&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="nx"&gt;initialState&lt;/span&gt;&lt;span class="p"&gt;;&lt;/span&gt;
&lt;span class="nx"&gt;state&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="nf"&gt;reducer&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="nx"&gt;state&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="p"&gt;{&lt;/span&gt; &lt;span class="na"&gt;type&lt;/span&gt;&lt;span class="p"&gt;:&lt;/span&gt; &lt;span class="dl"&gt;'&lt;/span&gt;&lt;span class="s1"&gt;INCREMENT&lt;/span&gt;&lt;span class="dl"&gt;'&lt;/span&gt; &lt;span class="p"&gt;});&lt;/span&gt;
&lt;span class="nx"&gt;console&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nf"&gt;log&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="nx"&gt;state&lt;/span&gt;&lt;span class="p"&gt;);&lt;/span&gt; &lt;span class="c1"&gt;// { count: 1 }&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;



&lt;h3&gt;
  
  
  Popularity and Statistics
&lt;/h3&gt;

&lt;p&gt;Immer.js has gained popularity in the React ecosystem with over 15,000 GitHub stars and numerous open-source projects using it for state management. It's actively maintained and receives updates and improvements regularly.&lt;br&gt;
&lt;a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F45c6k08467395vodi19j.png" class="article-body-image-wrapper"&gt;&lt;img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F45c6k08467395vodi19j.png" alt="Image description" width="363" height="75"&gt;&lt;/a&gt;&lt;/p&gt;

&lt;h3&gt;
  
  
  Immer.js vs. Redux
&lt;/h3&gt;

&lt;p&gt;Both Immer.js and Redux are popular choices for managing application state, but they have different approaches and use cases. Let's compare these two state management solutions to help you decide which one suits your needs.&lt;/p&gt;

&lt;h3&gt;
  
  
  Immer.js
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Immutability Made Easy&lt;/strong&gt;: Immer.js simplifies working with immutable data. It allows developers to directly modify the state as if it were mutable, automatically creating a new immutable state with the changes applied.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Simplicity&lt;/strong&gt;: Immer.js reduces boilerplate code, making state management code more readable and maintainable.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Efficiency&lt;/strong&gt;: Immer.js is designed for efficiency, minimizing the amount of data copied during updates, which is crucial for performance in large applications.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;React Integration&lt;/strong&gt;: Immer.js seamlessly integrates with React, making it a popular choice for React applications.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Learning Curve&lt;/strong&gt;: It has a relatively low learning curve, especially for developers familiar with mutable data.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Use Cases&lt;/strong&gt;: Immer.js is well-suited for simpler state management needs and smaller applications.&lt;/p&gt;&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  Redux
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Predictable State Management&lt;/strong&gt;: Redux offers a predictable and centralized state management system. It enforces one-way data flow, which can be helpful in larger and more complex applications.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Middleware&lt;/strong&gt;: Redux provides middleware support, allowing developers to add additional functionality such as logging, routing, or async operations.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Community and Ecosystem&lt;/strong&gt;: Redux has a large community and a wide range of middleware and extensions available, making it a versatile choice.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;DevTools&lt;/strong&gt;: Redux DevTools provide powerful debugging capabilities for tracking state changes.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Learning Curve&lt;/strong&gt;: Redux has a steeper learning curve, especially for those new to state management and immutable data concepts.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Use Cases&lt;/strong&gt;: Redux is an excellent choice for larger, complex applications where predictability, scalability, and middleware support are essential.&lt;/p&gt;&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  When to Choose Immer.js
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;Use Immer.js when simplicity and ease of use are a priority, and you're working on smaller to medium-sized applications.&lt;/li&gt;
&lt;li&gt;If you want to reduce the boilerplate code typically associated with immutability, Immer.js is an excellent choice.&lt;/li&gt;
&lt;li&gt;When you prefer an approach that allows you to work with mutable-like data while still maintaining immutability.&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  When to Choose Redux
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;Choose Redux for larger and more complex applications that require a high level of predictability and centralization.&lt;/li&gt;
&lt;li&gt;When you need extensive middleware support for routing, async operations, or custom extensions.&lt;/li&gt;
&lt;li&gt;If you value a well-established ecosystem with a wide range of community-contributed packages and Redux DevTools for debugging.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;In summary, the choice between Immer.js and Redux depends on the specific needs of your project. Immer.js simplifies state management and is great for smaller applications, while Redux offers a more structured and scalable solution, making it suitable for larger and more complex projects.&lt;/p&gt;

&lt;h3&gt;
  
  
  Conclusion
&lt;/h3&gt;

&lt;p&gt;Immer.js is a valuable library for simplifying state management in JavaScript applications, especially those using React. Its intuitive API, automatic cloning, and efficient updates make it a solid choice for developers working with complex state structures. While it may have a learning curve for newcomers, it quickly becomes an indispensable tool in your state management toolkit.&lt;/p&gt;

&lt;/h2&gt;

&lt;p&gt;React 19, slated for release in 2023, brings Concurrent Mode into the mainstream. This long-awaited feature is now stable and allows React applications to exhibit improved responsiveness and adaptability. Concurrent Mode ensures a smoother user experience by efficiently managing rendering priorities, especially beneficial for applications with complex UIs and varying network conditions.&lt;/p&gt;

&lt;h2&gt;
  
  
  2. Server Components
&lt;/h2&gt;

&lt;p&gt;A groundbreaking addition to React's arsenal is Server Components. With Server Components, developers can create portions of a UI that can be rendered both on the server and the client. This approach significantly enhances performance by reducing unnecessary client-side rendering and delivering a faster initial load.&lt;/p&gt;

&lt;h2&gt;
  
  
  3. Suspense for Data Fetching
&lt;/h2&gt;

&lt;p&gt;Managing asynchronous data loading in React applications becomes more straightforward with Suspense for Data Fetching. This feature streamlines the process of declaratively fetching data and managing loading states and errors. It simplifies code and enhances the user experience by ensuring that users see the UI in a consistent state.&lt;/p&gt;

&lt;h2&gt;
  
  
  4. Improved DevTools
&lt;/h2&gt;

&lt;p&gt;React DevTools, the browser extension for debugging React applications, is receiving substantial updates. These enhancements offer developers deeper insights into their application's behavior and performance. The improved DevTools aid in identifying and resolving issues more effectively, making development more efficient.&lt;/p&gt;

&lt;h2&gt;
  
  
  5. Enhanced Accessibility Support
&lt;/h2&gt;

&lt;p&gt;React remains committed to accessibility. In 2023, React's ecosystem will see additional features and improvements to facilitate the development of inclusive web applications. These enhancements will make it easier for developers to create web interfaces that are accessible to a wider audience.&lt;/p&gt;

&lt;p&gt;These exciting developments in React for 2023 empower developers to build more responsive, efficient, and accessible web applications. By embracing these new features and staying updated with React's evolving ecosystem, developers can continue to create cutting-edge web interfaces and deliver exceptional user experiences.&lt;/p&gt;

      <pubDate>Fri, 30 Jun 2023 07:05:38 +0000</pubDate>
      <link>https://dev.to/matek075/choosing-the-right-framework-or-library-for-a-web-application-a-comprehensive-guide-4ng3</link>
      <guid>https://dev.to/matek075/choosing-the-right-framework-or-library-for-a-web-application-a-comprehensive-guide-4ng3</guid>
      <description>&lt;p&gt;&lt;strong&gt;Introduction&lt;/strong&gt;:&lt;br&gt;
Selecting the appropriate framework or library is a crucial decision when developing a web application. It can significantly impact the project's success, development speed, maintainability, and scalability. In this detailed guide, we will delve into the various factors to consider when choosing a framework or library, along with a practical example to illustrate the decision-making process.&lt;/p&gt;




&lt;ul&gt;
&lt;li&gt;
&lt;u&gt;Project Requirements Analysis:&lt;/u&gt;
To begin, conduct a comprehensive analysis of your project requirements. For instance, consider whether you need server-side rendering (SSR), client-side rendering (CSR), or a hybrid approach. Determine the desired features, such as authentication, real-time updates, or data visualization. Identifying these requirements will help you narrow down the options and select a framework or library that meets your needs.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;em&gt;Example: Suppose you're developing a real-time collaborative task management application. Key requirements include real-time updates, user authentication, and responsive UI.&lt;/em&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;u&gt;Language Compatibility and Learning Curve:&lt;/u&gt;
Assess the programming languages associated with different frameworks or libraries. Evaluate your team's proficiency and comfort levels with those languages. Choosing a framework or library that aligns with your team's skills will accelerate the development process. Additionally, consider the learning curve, availability of learning resources, and community support for the chosen language.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;em&gt;Example: If your team is proficient in JavaScript and TypeScript, frameworks like React and libraries like Socket.io would be suitable choices.&lt;/em&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;u&gt;Community Support and Documentation:&lt;/u&gt;
Evaluate the strength of the framework or library's community support. A robust community ensures a vibrant ecosystem, timely bug fixes, and an extensive collection of third-party packages. Active forums, discussion groups, and dedicated support channels are valuable resources for troubleshooting and knowledge sharing. Thoroughly examine the documentation to gauge its comprehensiveness and clarity.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;em&gt;Example: React has a thriving community with an abundance of tutorials, online courses, and an extensive ecosystem of reusable components and libraries.&lt;/em&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;u&gt;Ecosystem and Third-Party Integrations:&lt;/u&gt;
Consider the ecosystem surrounding the framework or library. Explore the availability of plugins, extensions, and integrations with other tools commonly used in your project stack. A well-established ecosystem streamlines development, reduces reinventing the wheel, and promotes code reuse.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;em&gt;Example: React has a vast ecosystem with numerous third-party libraries like Redux, React Router, and Material-UI, allowing seamless integration with state management, routing, and UI components.&lt;/em&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;u&gt;Performance and Scalability:&lt;/u&gt;
Evaluate the performance benchmarks and scalability features of the framework or library. Examine factors like rendering speed, memory consumption, and support for server-side rendering or lazy loading. Consider the potential growth and increased user traffic your application may experience in the future.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;em&gt;Example: Next.js, a React framework, offers server-side rendering capabilities, optimizing initial page load time and improving search engine optimization (SEO).&lt;/em&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;u&gt;Long-Term Viability and Maintenance:&lt;/u&gt;
Consider the long-term viability of the framework or library. Examine its release cycle, community activity, and involvement of a dedicated team for maintenance and updates. An active and well-supported project is likely to address security vulnerabilities, provide regular updates, and offer long-term support.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;em&gt;Example: Angular, maintained by Google, has a stable release cycle and a large community actively contributing to its development and support.&lt;/em&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;u&gt;Case Studies and Industry Adoption:&lt;/u&gt;
Look for case studies or examples of successful projects built with the framework or library you are considering. Investigate its adoption in the industry, especially in projects similar to yours. Learning from real-world experiences can provide valuable insights into the pros and cons of each option.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;em&gt;Example: The popular e-commerce platform Shopify uses the Ruby on Rails framework for its backend, highlighting its suitability for building large-scale applications.&lt;/em&gt;&lt;/p&gt;




&lt;p&gt;&lt;strong&gt;Conclusion&lt;/strong&gt;:&lt;br&gt;
Choosing the right framework or library requires careful consideration of project requirements, language compatibility,&lt;br&gt;
community support, documentation, ecosystem, performance, long-term viability, and industry adoption. &lt;br&gt;
By thoroughly analyzing these factors and considering a practical example, you can make an informed decision. &lt;br&gt;
Remember, there is no one-size-fits-all solution, and it's essential to align the chosen tool with your specific project needs and team's expertise. &lt;br&gt;
Happy framework or library selection, and may your choice pave the way for a successful and efficient web application development journey!&lt;/p&gt;
