Package description

What is @types/express?

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.

What are @types/express's main functionalities?

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');
});
