MiniAPI - The Lightweight Node.js API Framework

MiniAPI is a blazing-fast, ultra-lightweight API framework for Node.js. At just 1KB, it provides essential routing, middleware, error handling, and more – all without dependencies.

🚀 Why MiniAPI?

• Ultra-Lightweight – Only 1KB in size!
• Zero Dependencies – Pure Node.js HTTP module.
• Express-Like API – Simple and intuitive routing.
• Middleware Support – Custom middleware for flexibility.
• Error Handling – Graceful error handling built-in.
• Grouped Routes – Organize APIs with prefixes.
• CORS Support – Enable Cross-Origin Resource Sharing.
• Rate Limiting & Compression – Optimize performance.
• Super Fast – Outperforms Express with minimal overhead.

💊 Performance Benchmarks

MiniAPI is significantly faster than Express:

| Framework | Requests/sec | Avg Response Time | | ----------- | ------------ | ----------------- | | MiniAPI | 12,000 | 3.20ms | | Express | 7,000 | 6.21ms |

Benchmark Setup:

• 10,000 requests with 50 concurrent connections.
• Lower response time = faster performance.

📦 Installation

npm install miniapi-framework

🛠 Basic Usage

import { createAPI } from 'miniapi-framework';

// Create API instance
const api = createAPI({
  logging: true,
  cors: true
});

// Define routes
api.get('/hello', (ctx) => {
  ctx.send({ message: 'Hello, World!' });
});

api.post('/echo', (ctx) => {
  ctx.send(ctx.body);
});

// Start the server
api.listen(3000, () => {
  console.log('Server running on http://localhost:3000');
});

⚡ Advanced Usage

Middleware Support

api.use(async (ctx, next) => {
  console.log(`Request: ${ctx.req.method} ${ctx.req.url}`);
  return next();
});

Route Parameters

api.get('/users/:id', (ctx) => {
  const userId = ctx.params.id;
  ctx.send({ id: userId, name: `User ${userId}` });
});

Grouped Routes

api.group('/api', (apiRouter) => {
  apiRouter.get('/users', (ctx) => {
    ctx.send([{ id: 1, name: 'User 1' }]);
  });
  
  apiRouter.get('/users/:id', (ctx) => {
    ctx.send({ id: ctx.params.id, name: `User ${ctx.params.id}` });
  });
});

Authentication Middleware

const auth = async (ctx, next) => {
  const token = ctx.req.headers['authorization'];
  
  if (!token || !token.startsWith('Bearer ')) {
    return ctx.send({ error: 'Unauthorized' }, 401);
  }
  
  // Validate token
  const apiKey = token.split(' ')[1];
  if (apiKey !== 'your-api-key') {
    return ctx.send({ error: 'Invalid API key' }, 401);
  }
  
  ctx.user = { id: 1, role: 'admin' };
  return next();
};

// Apply to specific routes
api.get('/protected', auth, (ctx) => {
  ctx.send({ message: 'Protected data', user: ctx.user });
});

Error Handling

api.onError((error, ctx) => {
  console.error('Error:', error);
  ctx.send({ error: 'Internal Server Error' }, 500);
  return true; // Error was handled
});

Response Methods

// JSON response (default)
ctx.send({ data: 'example' }, 200);

// Text response
ctx.text('Plain text response', 200);

// HTML response
ctx.html('<h1>Hello World</h1>', 200);

// Redirect
ctx.redirect('/new-location', 302);

🔐 API Reference

Creating an API Instance

const api = createAPI(options);

Options:

Routing Methods

api.get(path, handler);
api.post(path, handler);
api.put(path, handler);
api.delete(path, handler);
api.patch(path, handler);

Context Object Properties

| Property | Description | | -------- | -------------------------------- | | req | Original Node.js request object | | res | Original Node.js response object | | params | URL parameters | | query | Query string parameters | | body | Parsed request body |

🌐 Complete Example

import { createAPI } from 'miniapi-framework';

// Create API instance with options
const api = createAPI({
  logging: true,
  cors: true,
  compression: true,
  rateLimit: true
});

// Global middleware
api.use(async (ctx, next) => {
  ctx.requestTime = new Date();
  ctx.res.setHeader('X-Powered-By', 'MiniAPI');
  return next();
});

// Basic routes
api.get('/', (ctx) => {
  ctx.send({ 
    message: 'Welcome to MiniAPI!',
    timestamp: ctx.requestTime.toISOString()
  });
});

// API routes group
api.group('/api', (apiRouter) => {
  apiRouter.get('/users', (ctx) => {
    const users = [
      { id: 1, name: 'Alice' },
      { id: 2, name: 'Bob' }
    ];
    ctx.send({ users });
  });
  
  apiRouter.get('/users/:id', (ctx) => {
    const userId = ctx.params.id;
    ctx.send({ id: userId, name: `User ${userId}` });
  });
  
  apiRouter.post('/users', (ctx) => {
    if (!ctx.body || !ctx.body.name) {
      return ctx.send({ error: 'Name is required' }, 400);
    }
    
    ctx.send({ 
      message: 'User created',
      user: {
        id: 3,
        name: ctx.body.name,
        createdAt: new Date().toISOString()
      }
    }, 201);
  });
});

// Error handling
api.onError((error, ctx) => {
  console.error('Error:', error);
  ctx.send({ error: 'Internal Server Error' }, 500);
  return true;
});

// Start the server
api.listen(3000, (server) => {
  console.log('🚀 MiniAPI server running on http://localhost:3000');
});
