8 Lesser-Known AI Projects to Improve Your Developer Productivity ⚡️🔥

Madza ・ Jul 24

You will never be this surrounded by potential again.

Marcos Silva — Tue, 20 May 2025 22:14:43 +0000

College isn’t just about grades or diplomas it’s a launchpad 🚀

I’ve never been around so many curious minds, spontaneous ideas, and people who are still brave enough to experiment without fear of failure.

The university environment is underrated for technical growth.

You're in a space where everyone is learning, building, and asking:

“How does this work?” 🤔

And that energy is contagious.

You don’t need to wait for a job to become a developer.

The best time to start growing technically is when you're already surrounded by people who want to grow with you.

Most of my freshers ask me the same thing:

“How can I break into the market faster?” 💼

And I get it everyone wants to gain experience, build a career, feel ready.

But here’s what they don’t always realize:

👉 You can get real experience while you’re still in college.

Who hasn’t been caught in a hallway conversation and heard something like:

🗣️ “Bro, imagine if we built an app that did this…”

🧪 “I just found this crazy new library, wanna try it out?”

🚢 “It doesn’t need to be perfect let’s just launch and see what happens.”

Those moments are gold. ✨

Some of the best developers I know didn’t wait to be “ready”

they just started.

And college gave them the perfect playground to do it. 🎮👨‍💻

How We Use Our APP to Build Our APP

Marcos Silva — Thu, 13 Feb 2025 20:13:53 +0000

At Webcrumbs.ai, we do something pretty wild... we use our product to build our product!

Ok, but how does that even work? 🤔

Well, whenever we have a design idea, instead of jumping into Figma or any other design tool, we just ask Frontend AI to build it—inside Frontend AI!

Yes, it's frontend inception.

✅ Navbar? Built with Frontend AI.

✅ Left Panel? Generated right here.

✅ Theme Selector, Color Scheme Picker, layout adjustments? All created inside the tool itself!

It’s like watching AI bootstrap itself, and honestly, it’s pretty cool.

Take a look of our Quickstart:

I uploaded this image in Frontend AI and ask the Frontend AI to change it!

The Meta Loop of Frontend Development

We’re not just building UI components; we’re creating an AI-driven development experience where the tool designs itself. Every feature you see—from the templates section to the quality check tools—was made using the very tool you’re using now.

🚀 Frontend AI isn’t just a tool; it’s a workflow revolution.

So... What’s Next?

With each iteration, Frontend AI gets smarter, faster, and more intuitive.

And yes, we’re planning to push this self-building concept even further. And we've never seen this before.

We’d love to hear your thoughts! What would you build inside AI, using AI? 🤖🔥

JavaScript Tips in 5 Minutes! 🚀

Marcos Silva — Tue, 30 Jul 2024 19:04:03 +0000

1. Use `let` and `const` Over `var`

🔥 Why?

Scope: let and const are block-scoped, making your code more predictable and avoiding those nasty bugs.
Hoisting: They don't suffer from the hoisting issues var does.

let score = 100; // Use for variables that will change
const pi = 3.14159; // Use for constants

2. Master Arrow Functions

🔥 Why?

Concise: Cleaner and shorter syntax.
Lexical this: They do not bind their own this, which can be very handy.

const add = (a, b) => a + b;
console.log(add(2, 3)); // Output: 5

3. Template Literals for Better Strings

🔥 Why?

Readability: Easier to read and write strings, especially with variables.
Multi-line Strings: No need for awkward concatenation or escaping.

const name = 'Alice';
const greeting = `Hello, ${name}! Welcome to Wonderland.`;
console.log(greeting);

4. Destructure for Simplicity

🔥 Why?

Clarity: Makes your code more readable and concise.
Efficiency: Pulls out exactly what you need from objects and arrays.

const user = { name: 'John', age: 30 };
const { name, age } = user;
console.log(name, age); // Output: John 30

5. Use Default Parameters

🔥 Why?

Safety: Ensures functions have sensible default values.
Simplicity: Reduces the need for manual checks.

function greet(name = 'Stranger') {
  return `Hello, ${name}!`;
}
console.log(greet()); // Output: Hello, Stranger!

6. Spread and Rest Operators

🔥 Why?

Versatility: Spread (...) and rest (...) operators simplify many tasks like copying arrays, merging objects, and handling function arguments.

// Spread
const arr1 = [1, 2, 3];
const arr2 = [...arr1, 4, 5, 6];
console.log(arr2); // Output: [1, 2, 3, 4, 5, 6]

// Rest
function sum(...args) {
  return args.reduce((acc, curr) => acc + curr, 0);
}
console.log(sum(1, 2, 3)); // Output: 6

7. Short-Circuit Evaluation

🔥 Why?

Efficiency: Helps in writing concise and safer code, especially with default values.

const name = user && user.name;
const defaultValue = input || 'default';

8. Optional Chaining

🔥 Why?

Safety: Avoids errors when accessing deeply nested properties.

const user = { address: { city: 'Paris' } };
const city = user?.address?.city;
console.log(city); // Output: Paris

9. Avoid `==` and Use `===`

🔥 Why?

Precision: === checks for both value and type, reducing unexpected behavior.

console.log(0 == false); // Output: true
console.log(0 === false); // Output: false

10. Keep Your Code DRY

🔥 Why?

Maintainability: DRY (Don’t Repeat Yourself) principles make your code easier to maintain and understand.

function calculateTotal(price, tax) {
  return price * (1 + tax);
}

const item1Total = calculateTotal(100, 0.15);
const item2Total = calculateTotal(200, 0.15);

Remember, the best way to learn is by doing. So, pick a tip, try it out, and watch your code transform! 🔄

Cheers! 🍻

Short Overview: Frontend Architectures 🧩

Marcos Silva — Thu, 20 Jun 2024 18:22:26 +0000

Frontend architectures define how the components of a web application are organized and interact. Here are some common types:

Monolithic Architecture 🏛️

Single Codebase: Everything is in one place.
Pros: Simple to set up and maintain.
Cons: Hard to scale, changes affect the entire app.

Micro Frontends 🧩

Multiple Independent Frontends: Each frontend is a self-contained micro-app.
Pros: Scalable, team autonomy.
Cons: Complex to integrate, potential for inconsistencies.

Single-Page Application (SPA) 🖥️

Dynamic Loading: Loads a single HTML page and updates dynamically.
Pros: Fast and smooth user experience.
Cons: Initial load time can be slow, SEO challenges.

Multi-Page Application (MPA) 📄📄

Separate Pages: Each interaction loads a new page.
Pros: Better SEO, simpler initial load.
Cons: Slower navigation, more server load.

Server-Side Rendering (SSR) 🏗️

Pre-Rendered on Server: Pages are generated on the server before being sent to the client.
Pros: Better for SEO, fast initial load.
Cons: More complex server setup, potentially slower page transitions.

Static Site Generation (SSG) 🗂️

Pre-Built Pages: Pages are pre-rendered at build time.
Pros: Fast load times, great for SEO.
Cons: Not suitable for highly dynamic content.

Progressive Web App (PWA) 📲

Hybrid of Web and Mobile: Web apps that provide a mobile app-like experience.
Pros: Offline capabilities, app-like experience.
Cons: Limited access to device features compared to native apps.

Each frontend architecture comes with its own set of benefits and trade-offs. The optimal choice hinges on your project’s unique requirements and goals. Understanding these different architectures enables you to make informed decisions that lead to the creation of robust, scalable, and maintainable web applications.

Thank you.

Short Overview: A guide of Auth in JS 🛡️

Marcos Silva — Mon, 17 Jun 2024 13:33:32 +0000

Let's Take It Quick!

After you start your project, make sure to install all dependencies:

npm install axios react-router-dom

This way, you already have all the dependencies to create authentication for your project!

Login Component

The second step is creating your login component, so you can input the login information.
You need to import useState to manage form input state and useHistory to redirect users after successful login.

import React, { useState } from 'react';
import axios from 'axios';
import { useHistory } from 'react-router-dom';

const Login = () => {
  const [email, setEmail] = useState('');
  const [password, setPassword] = useState('');
  const history = useHistory();

  const handleSubmit = async (e) => {
    e.preventDefault();
    try {
      const response = await axios.post('/api/login', { email, password });
      if (response.data.success) {
        localStorage.setItem('token', response.data.token);
        history.push('/dashboard');
      } else {
        alert('Invalid credentials');
      }
    } catch (error) {
      console.error('Login error:', error);
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <h2>Login</h2>
      <input
        type="email"
        placeholder="Email"
        value={email}
        onChange={(e) => setEmail(e.target.value)}
        required
      />
      <input
        type="password"
        placeholder="Password"
        value={password}
        onChange={(e) => setPassword(e.target.value)}
        required
      />
      <button type="submit">Login</button>
    </form>
  );
};

export default Login;

Setting Your Routes

In src/App.js, set up the routes. Import BrowserRouter, Route, and Switch from react-router-dom to define the routes. This sets up two routes: one for the login page and one for the dashboard.

import React from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
import Login from './Login';
import Dashboard from './Dashboard';

function App() {
  return (
    <Router>
      <Switch>
        <Route path="/" exact component={Login} />
        <Route path="/dashboard" component={Dashboard} />
      </Switch>
    </Router>
  );
}

export default App;

Creating Private Routes

Create the PrivateRoute.js component to protect your routes. This component will check if the user is authenticated before granting access.

import React from 'react';
import { Route, Redirect } from 'react-router-dom';

const PrivateRoute = ({ component: Component, ...rest }) => {
  const isAuthenticated = !!localStorage.getItem('token');

  return (
    <Route
      {...rest}
      render={(props) =>
        isAuthenticated ? <Component {...props} /> : <Redirect to="/" />
      }
    />
  );
};

export default PrivateRoute;

Update your routing in App.js to use the PrivateRoute for the dashboard.

<PrivateRoute path="/dashboard" component={Dashboard} />

Backend API

This code will be validating a user's email and password and returning a JSON Web Token (JWT).

const express = require('express');
const jwt = require('jsonwebtoken');
const bodyParser = require('body-parser');
const app = express();

app.use(bodyParser.json());

app.post('/api/login', (req, res) => {
  const { email, password } = req.body;

  if (email === 'test@example.com' && password === 'password123') {
    const token = jwt.sign({ email }, 'your_jwt_secret', { expiresIn: '1h' });
    return res.json({ success: true, token });
  }

  res.json({ success: false, message: 'Invalid credentials' });
});

app.listen(5000, () => {
  console.log('Server is running on port 5000');
});

Tips

After a successful login, store the JWT token in localStorage. To keep it secure:

Do not store sensitive information in the token.
Use HTTPS to encrypt data in transit.
Implement token expiration and refresh mechanisms.

Thank you.
