@types/express
Advanced tools
Package description
The @types/express package provides TypeScript type definitions for Express, a fast, unopinionated, minimalist web framework for Node.js. This allows developers to use Express in TypeScript projects with type checking, enabling better development practices, autocompletion in code editors, and ensuring API usage correctness.
Application Creation
This feature allows developers to create a new Express application. The code sample demonstrates how to import Express and initialize a new app instance.
import express from 'express';
const app = express();Middleware Integration
Middleware functions can process the incoming requests before your routes. This code sample shows how to use the built-in middleware to parse JSON bodies.
app.use(express.json());Routing
Express allows you to define routes based on HTTP methods and paths. The code sample demonstrates creating a simple GET route that responds with 'Hello World'.
app.get('/path', (req, res) => {
res.send('Hello World');
});Provides TypeScript definitions for Koa, a web framework designed by the creators of Express, aiming to be a smaller, more expressive, and more robust foundation for web applications and APIs. Koa uses async functions, which allows for a simpler and more powerful way to handle asynchronous operations compared to Express.
Offers TypeScript type definitions for hapi, a rich framework for building applications and services. hapi is designed to be more configurable and extensible than Express, providing a robust plugin system. It differs from Express in its configuration-centric approach versus Express's code-centric approach.
Provides TypeScript definitions for Fastify, a fast and low overhead web framework for Node.js. Fastify is focused on providing a faster alternative to Express with an emphasis on performance and low overhead. It offers a different set of features like schema-based request and response validation which is not native to Express.
