Koa-router is a router middleware designed for Koa, a next-generation web framework for Node.js. It offers a range of powerful features including but not limited to, Express-style routing (get, put, post, and more), named URL parameters, support for OPTIONS requests with allowed methods, and asynchronous operations with async/await support. The koa-router is maintained by Forward Email and Lad.
To install and use koa-router in your project, first, you need to have Node.js and npm (node package manager) installed. Then, you can install koa-router with npm using the following command:
npm install @koa/router
For TypeScript users, you can install types for koa-router using the command:
npm install @types/koa__router
To use the router in your Koa application, you create a new router instance and define routes for your application, for example:
const Koa = require('koa');
const Router = require('@koa/router');
const app = new Koa();
const router = new Router();
router.get('/', async (ctx, next) => {
ctx.body = 'Hello, World!';
});
app.use(router.routes());
app.listen(3000);
In this sample, we have defined a simple GET endpoint at the route '/' that responds with the string 'Hello, World!'.
The comprehensive API documentation and further details about koa-router can be found in the API.md file associated with the official GitHub repository of koa-router. It provides a detailed overview of all the methods and properties supported by koa-router, as well as clear, easy-to-follow examples to help you get the most out of this flexible routing middleware.
