Advanced tools
Package description
The h3 npm package is a high-performance HTTP framework for Node.js, designed to be lightweight and fast. It is often used for building APIs and microservices, providing a simple and efficient way to handle HTTP requests and responses.
Basic HTTP Server
This code demonstrates how to create a basic HTTP server using the h3 package. The server listens on port 3000 and responds with 'Hello, world!' to any incoming requests.
const { createApp } = require('h3');
const { createServer } = require('http');
const app = createApp();
app.use('/', (req, res) => {
res.end('Hello, world!');
});
createServer(app).listen(3000, () => {
console.log('Server is running on http://localhost:3000');
});Middleware Support
This example shows how to use middleware with the h3 package. The middleware logs each incoming request's method and URL before passing control to the next handler.
const { createApp } = require('h3');
const { createServer } = require('http');
const app = createApp();
// Middleware to log requests
app.use((req, res, next) => {
console.log(`${req.method} ${req.url}`);
next();
});
app.use('/', (req, res) => {
res.end('Hello, world!');
});
createServer(app).listen(3000, () => {
console.log('Server is running on http://localhost:3000');
});Routing
This code demonstrates how to set up routing with the h3 package. It defines GET and POST routes for the '/hello' path, responding with different messages based on the HTTP method.
const { createApp, useRouter } = require('h3');
const { createServer } = require('http');
const app = createApp();
const router = useRouter();
router.get('/hello', (req, res) => {
res.end('Hello, GET!');
});
router.post('/hello', (req, res) => {
res.end('Hello, POST!');
});
app.use(router);
createServer(app).listen(3000, () => {
console.log('Server is running on http://localhost:3000');
});Express is a widely-used web application framework for Node.js, known for its simplicity and flexibility. It provides robust routing, middleware support, and a wide range of HTTP utility methods. Compared to h3, Express is more feature-rich and has a larger community, but it may be heavier and less performant for certain use cases.
Koa is a next-generation web framework for Node.js, created by the same team behind Express. It uses async functions to simplify middleware and improve error handling. Koa is more modular and lightweight compared to Express, similar to h3, but it requires more boilerplate code to set up.
Fastify is a web framework for Node.js that focuses on performance and low overhead. It provides a schema-based validation system and a powerful plugin architecture. Fastify is similar to h3 in terms of performance and simplicity, but it offers more built-in features and a more extensive plugin ecosystem.
