What is async / await in JavaScript?

ben ajaero — Wed, 06 Mar 2024 12:19:20 +0000

Before we dive into the nitty-gritty of async and await, let's set the stage. JavaScript, by nature, is non-blocking and asynchronous. This means it doesn't wait around for an operation to complete before moving on to the next one, which is great for keeping things snappy. But what about when you need to perform tasks that depend on the results of previous ones? Enter the world of asynchronous programming — a realm where managing sequences of operations without getting tangled up can be quite the challenge.

Traditionally, we relied on callbacks to handle these scenarios. But callbacks come with their own set of problems, often leading to the infamous "callback hell," where you're stuck in a maze of nested functions, losing sight of clarity and simplicity.

Promises: A Step Forward

Promises stepped onto the scene with a promise (pun intended) of simplifying asynchronous code. They represent a future value — a pledge that at some point, there will be a result, be it a successful one or an error. By using .then() and .catch(), they allow us to write asynchronous code that's more structured and easier to follow than the callback jungle.

However, even with promises, the code can become cumbersome, especially when dealing with complex sequences of async operations. That's where async and await come into play, offering a cleaner and more intuitive way to work with promises.

Understanding async / await

Imagine you could write asynchronous code that looks and behaves like synchronous code. That's the superpower async and await grant you.

The `async` Function

An async function is a special type of function that simplifies the way we write promise-based code. By adding the async keyword before a function declaration, you transform it into a promise-based powerhouse. Here's the kicker: any async function automatically returns a promise.

async function fetchData() {
  // This function now returns a promise
}

The `await` Operator

The await operator works hand in hand with async functions. It tells JavaScript to pause the execution of the async function until the promise resolves. The beauty of await is that it unwraps the fulfilled value from the promise, allowing you to handle it as if it were a regular synchronous return value.

async function fetchData() {
  let data = await fetch('https://api.example.com/data');
  console.log(data); // This logs the resolved value of the fetch promise
}

Note how the await keyword halts the execution of fetchData until fetch resolves, giving us clean, synchronous-looking code that's actually asynchronous under the hood.

Handling Errors Gracefully

One of the perks of async and await is how they simplify error handling. By using a try/catch block, you can handle both synchronous and asynchronous errors with the same construct, making your code cleaner and more consistent.

async function fetchData() {
  try {
    let data = await fetch('https://api.example.com/data');
    console.log(data);
  } catch (error) {
    console.error('Oops, something went wrong:', error);
  }
}

Sorting Elements By a Certain Property

Perfect for lists that require dynamic ordering.

const sortBy = (arr, key) => arr.sort((a, b) => a[key] > b[key] ? 1 : -1);

Convert String to camelCase

el casing is integral in Javascript for variable naming conventions.

const toCamelCase = (str) => str.trim().replace(/_\s]+(.)?/g, (_, c) => (c ? c.toUpperCase() : ''));

Folding a Long Line Without Breaking Words

Ideal for text formatting in UI elements space is constrained.

const foldLine = (line, maxChars) => line.replace(new RegExp(`(.{1,${maxChars}})(\\s+|$)`, 'g'), '$1\n').trim();

Escape HTML Special Characters

To prevent XSS attacks, escaping input is crucial:

const escapeHTML = (str) => str.replace(/[&<>"']/g, (m) => ({ '&': '&amp;', '<': '&lt;', '>': '&gt;', '"': '&quot;', "'": '&#39;' }[m]));

Reverse a String

It's simple yet frequently for algorithms and logic puzzles.

const reverseString = str => str.split('').reverse().join('');

Snippets in Modern Editors

For developers using frameworks like React, IDEs offer snippets such as af, rfc, and rafce, which generate anonymous function, React functional component, and React arrow function component with export respectively.

Javascript One-Liners FAQs

How We Achieved a Perfect 100 Google PageSpeed Score with Astro.js and Partial Hydration

ben ajaero — Fri, 09 Feb 2024 03:26:52 +0000

At Cox Code, we're excited to share our journey on achieving a perfect 100 Google PageSpeed Score, which is no small feat. In a world where user experience can make or break a website's success, we took on the challenge head-on. We turned to Astro.js and the concept of partial hydration to give our users a lightning-fast, seamless experience. Let’s dive into the steps we took and the technologies we used to enhance our Core Web Vitals and achieve contentful load perfection.

Understanding Core Web Vitals

Before we could start optimizing, we needed to understand what we were optimizing for. Core Web Vitals are a set of metrics that Google considers crucial to a website’s overall user experience. They include:

Largest Contentful Paint (LCP): Measures the load time of the main content on a page.
First Input Delay (FID): Assesses the time from when a user first interacts with your site to the time the browser can respond to that interaction.
Cumulative Layout Shift (CLS): Quantifies the amount of unexpected layout shift during the visual rendering of the webpage.

Improving these metrics was essential for a better user experience and for our SEO rankings.

Choosing Astro.js

Astro.js emerged as a leading solution due to its innovative approach to web development. It’s a static site generator that allows for building websites with a modern UI framework, yet it outputs the minimum amount of JavaScript needed. This approach aligns perfectly with the goal of optimizing Core Web Vitals, as it reduces JavaScript bloat, leading to faster load times, lower FID, and minimal CLS.

The Role of Partial Hydration

Astro.js uses a technique called partial hydration, which hydrates only the interactive components of a webpage rather than the entire page. This means that users only download the JavaScript they need, which drastically reduces the time to become interactive. This selective hydration plays a pivotal role in achieving high Core Web Vitals scores.

Our Approach to Optimization

Here’s how we leveraged Astro.js and other strategies to optimize our website:

Step 1: Minimal Initial Load

We used Astro.js to build our site with static rendering, which ensures that the initial load sent to the browser is minimal. We carefully analyzed our design components and only applied hydration to components that required interactivity.

Step 2: Optimize Images and Media

We optimized all our images and media files using modern formats like WebP and AVIF, which offer better compression and quality than traditional formats. Additionally, we implemented lazy loading so that images only load when they enter the viewport.

Step 3: Efficient CSS and Fonts

We paid special attention to our CSS, removing any unused styles with tools like PurgeCSS. We also optimized font delivery by selecting only the necessary font weights and styles and used font-display: swap to ensure text remains visible during font loading.

Step 4: Reducing Third-Party Scripts

Third-party scripts can be a significant drag on performance. We audited all scripts and removed any that were non-essential. For the ones we kept, we made sure to load them asynchronously or defer them to avoid blocking the main thread.

Step 5: Caching and CDNs

To ensure that repeat visits were just as fast as the first, we implemented aggressive caching strategies and distributed our content across a global CDN. This reduced latency and made sure our static assets were delivered quickly.

Step 6: Continuous Monitoring and Testing

We used tools like Lighthouse, WebPageTest, and Google's own PageSpeed Insights to continuously monitor our performance. This allowed us to catch regressions and make iterative improvements.

The Result

After implementing these strategies, we re-ran our PageSpeed Insights test and were thrilled to see that big, beautiful "100" score for both mobile and desktop. Our LCP dropped below the 2.5-second threshold, FID was well under 100 milliseconds, and our CLS was virtually zero.

Conclusion

Achieving a perfect Google PageSpeed Score is not just about bragging rights; it's about providing the best possible experience for our users. By leveraging Astro.js and partial hydration, along with a slew of other performance best practices, we were able to deliver a blazing-fast, efficient, and enjoyable web experience. Our journey to 100 is a testament to the power of modern web development techniques and the endless possibilities when you prioritize performance.

Gardeners and Architects: The Agile and Waterfall Methodologies in Software Development

ben ajaero — Tue, 06 Feb 2024 08:30:17 +0000

The Metaphor of Minds and Methods

George R.R Martin said

“I think there are two types of writers, the architects and the gardeners. The architects plan everything ahead of time, like an architect building a house. They know how many rooms are going to be in the house, what kind of roof they’re going to have, where the wires are going to run, what kind of plumbing there’s going to be. They have the whole thing designed and blueprinted out before they even nail the first board up. The gardeners dig a hole, drop in a seed and water it. They kind of know what seed it is, they know if planted a fantasy seed or mystery seed or whatever. But as the plant comes up and they water it, they don’t know how many branches it’s going to have, they find out as it grows. And I’m much more a gardener than an architect.”

The Metaphor of Minds and Methods

Each mind is akin to fertile soil, where thoughts take root and flourish in their unique manner. Some individuals conceive grand designs before initiating any action, while others prefer their ideas to evolve progressively, cultivated with attentive care. These divergent approaches are mirrored in the realms of coding and prose.

The Architectural Approach

The architects envision the completed project before commencing, placing each element meticulously according to a blueprint conceived in their imagination. Their code, much like edifices, stands resiliently, supported by deep foundations and robust connections. However, such rigidly constructed systems may demonstrate limited flexibility as time progresses and requirements evolve.

The Gardening Approach

Conversely, the gardeners of the software development world sow seeds and attentively observe their growth, influenced more by environmental factors and feedback than by predetermined schematics. Their creations may wander and evolve, yet they benefit from the intimate understanding gained through iterative refinement. A concept that begins as a mere seedling can flourish into a robust feature through continuous care and adaptive learning.

The Merit of Both Philosophies

Both philosophies hold their own merits, and many developers embody traits from both archetypes. The astuteness lies in recognizing when to apply each approach, as architectural planning anticipates the long-term scope, whereas the gardening mindset adapts to immediate changes and organic growth. Together, they offer a balanced symbiosis.

Methodology in Practice

In practice, the choice of methodology—be it Agile or Waterfall—must align with the nature of the project at hand. Agile methodologies foster an environment of continuous iteration and adaptability, welcoming changes even late in the development process. Waterfall, in contrast, provides a structured linear progression, laying a comprehensive foundation before any development begins, which can be beneficial for projects requiring a high level of certainty and a clear, unchanging direction.

Conclusion: The Essence of Software Development

Ultimately, the success of a software development project is less about the adherence to a particular methodology and more about how developers harness their capabilities. Whether one identifies more with the precision of an architect or the adaptability of a gardener, the goal remains the same: to find equilibrium and create software that is both functional and enduring. By valuing diverse perspectives and skills, and adapting to the ever-changing landscape of user needs and technological advancements, our creations are more likely to stand the test of time and meet the demands of users and stakeholders alike.

Setting Up Razor Support in Neovim for Enhanced C# Development

ben ajaero — Fri, 26 Jan 2024 18:30:48 +0000

When working with C# in web development scenarios, especially when dealing with ASP.NET Core projects, having support for Razor can significantly improve your productivity. Fortunately, Neovim’s flexibility allows you to set up a development environment tailored to your needs. Here’s how you can integrate Razor support into your Neovim setup.

Step 1: Install the vim-vsnip Plugin

First things first, a snippet plugin can be a real time-saver. vim-vsnip is a popular choice among Neovim users. To install it using vim-plug, add this line to your init.vim:

Plug 'hrsh7th/vim-vsnip'

https://github.com/hrsh7th/vim-vsnip

Afterwards, run :PlugInstall in Neovim to get the plugin installed.

Step 2: Add vim-csharp to Neovim

The vim-csharp plugin adds nice enhancements for C# development. To include it in your toolset, simply place this line in your init.vim under the plugins section:

Plug 'OrangeT/vim-csharp'

https://github.com/OrangeT/vim-csharp

Save your changes and run :PlugInstall to finalize the addition.

Step 3: Locate Your Snippet Directory

vim-vsnip will need to know where to find your snippets. To discover the default snippet directory, issue the following command in Neovim:

:echo(vsnip_snippets_dir)

Note down the directory path that appears—it’s typically found at ~/.vsnip.

Step 4: Copy Snippet Files to the Right Place

Now, you need to copy the snippet files from vim-csharp to your vim-vsnip snippet directory. If you installed the plugin via vim-plug, they should be located in ~/.local/share/nvim/plugged/vim-csharp/snippets. Use this command in your terminal to move them over:

cp ~/.local/share/nvim/plugged/vim-csharp/snippets/*.snippets ~/.vsnip

Adjust the paths as necessary if your setup differs.

Step 5: Configure Neovim for Razor Files

For Neovim to recognize .cshtml and .razor files and associate them with the proper filetype, include these lines in your init.vim:

autocmd BufNewFile,BufRead *.cshtml set filetype=html.cshtml.razor
autocmd BufNewFile,BufRead *.razor set filetype=html.cshtml.razor

With these settings, Neovim will apply the correct syntax highlighting and other filetype-specific behaviors for Razor files.

You can also install Mason and Nvim-cmp if you would like those features.

By following through with these steps, you've now equipped Neovim with a sharper edge for C# and Razor development, paving the way for a more streamlined coding experience. Whether it’s crafting intricate Razor pages or diving deep into C# logic, your Neovim setup is now up to the task.

Local Storage in 5 mins: A Beginner’s Guide to Cookies, localStorage, and sessionStorage

ben ajaero — Thu, 18 Jan 2024 14:14:27 +0000

As web applications continue to evolve into robust experiences resembling native apps, the need for local data storage on the client-side becomes increasingly important. Technologies like cookies, localStorage, and sessionStorage provide frontend developers with various options for temporarily caching data within the browser.

In this article, we'll explore the key differences between these three storage mechanisms and how each can be leveraged appropriately based on an application's specific data needs. By understanding the capabilities and limitations of each, you can architect your client-side code for optimal performance while avoiding common pitfalls.

Cookies: The Sticky Notes of the Web

Cookies have been around since the early days of the web and remain one of the most basic forms of client-side storage. Primarily used for authentication, cookies allow servers to uniquely identify returning users by storing a small amount of data on their machine.

However, cookies come with limitations. Each cookie can only hold up to 4kb of data formatted as a single string, making them ill-suited for structured or large datasets. Additionally, every request to the server will attach all cookie headers, increasing bandwidth consumption.

For these reasons, cookies are best used sparingly - to store things like user IDs, preferences, or session tokens. Libraries exist to simplify encoding/decoding of cookie values to dictionary formats.

// Setting a cookie without a library
document.cookie = "username=JohnDoe; expires=Thu, 18 Dec 2023 12:00:00 UTC; path=/";

// Using a library to set a cookie
Cookies.set('username', 'JohnDoe', { expires: 7, path: '/' });

Libraries like js-cookie provide convenient methods for getting and setting cookies, dealing with the nuances of string parsing under the hood.

localStorage: The Whiteboard

localStorage is like having a whiteboard in your home. You can write down reminders that stay there until you erase them. localStorage provides a more robust alternative to cookies for locally caching larger amounts of structured data. Values are stored as key-value pairs that can be accessed on all pages of a domain, persisting even when the browser is closed.

This makes localStorage ideal for caching dynamic responses, application states, or content likely to be reused across sessions. Developers have up to 5-10mb of storage per origin, though browser support varies.

// Setting an item in localStorage
localStorage.setItem('favoriteColor', 'blue');
// Getting that item back
let favoriteColor = localStorage.getItem('favoriteColor');

SessionStorage: The Notepad

Similar to localStorage, sessionStorage (up to 5mb) also uses a key-value data structure but will only persist for the lifetime of the browser tab or window it was created in. Data is removed once the tab closes.

Well-suited for multi-step workflows, sessionStorage enables locally caching intermediate states or contextual data meant to enhance the user experience on a single page load.

// Setting an item in sessionStorage
sessionStorage.setItem('toDoList', 'Buy milk');
// Getting that item back
let toDoList = sessionStorage.getItem('toDoList');

Managing Your Storage

To maintain organized and efficient data stores, periodic cleaning can be helpful. Through the Storage API, you can remove individual items as well as empty the entirety of cached data:

Remove a specific item: localStorage.removeItem('favoriteColor');
Clear everything: localStorage.clear();

The same methods apply for sessionStorage.

Using Storage in React with Hooks

React's hooks allow you to interact with local storage in a more intuitive way, abstracting complex operations into simple function calls. Here's how you can create a custom hook to manage localStorage in your React apps:

import { useState, useEffect } from 'react';

function useLocalStorage(key, initialValue) {
    const [storedValue, setStoredValue] = useState(() => {
        try {
            const item = window.localStorage.getItem(key);
            // Parse stored json or if none return initialValue
            return item ? JSON.parse(item) : initialValue;
        } catch (error) {
            // If error also return initialValue
            console.error(error);
            return initialValue;
        }
    });

    // Return a wrapped version of useState's setter function
    // This ensures we're always storing a string
    const setValue = (value) => {
        try {
            // Allow value to be a function so we have the same API as useState
            const valueToStore =
                value instanceof Function ? value(storedValue) : value;
            // Save state
            setStoredValue(valueToStore);
            // Save to local storage
            window.localStorage.setItem(key, JSON.stringify(valueToStore));
        } catch (error) {
            // A more advanced implementation would handle the error case
            console.error(error);
        }
    };

    useEffect(() => {
        setValue(storedValue);
        // eslint-disable-next-line react-hooks/exhaustive-deps
    }, [key, storedValue]);

    return [storedValue, setValue];
}

// Example usage of the hook in a component
function App() {
    const [name, setName] = useLocalStorage('name', 'Alice');

    return (
        <div>
            <input
                type="text"
                value={name}
                onChange={(e) => setName(e.target.value)}
            />
        </div>
    );
}

export default App;

The Future: Secure Alternatives

While cookies, localStorage and sessionStorage empower versatile application functionality through client-side data caching, several security limitations remain that developers must carefully consider.

As currently implemented, any JavaScript loaded onto a page possesses the ability to access stored values, posing risks if sensitive information is involved. No built-in protection from unauthorized retrieval or modification exists.

Recognizing such concerns, upcoming standards propose enhancements strengthening data confidentiality.

In the meantime, best practices involve judiciously avoiding PII or credential placement within browsers' storage APIs directly. Leverage server-side sessions instead when appropriate. Similarly, exercise caution with third-party code integration to minimize exposure.
