@loopback/rest

The REST API package for loopback-next.

Overview

This component provides a REST server for your application instances, complete with:

• new custom routing engine (special thanks to @bajtos)!
• tools for defining your application routes
• OpenAPI 3.0 spec (openapi.json/openapi.yaml) generation using @loopback/openapi-v3
• a default sequence implementation to manage the request and response lifecycle

NOTE: Starting from 6.0.0, we have introduced a middleware-based sequence, which is is used as the default one for newly generated LoopBack applications using lb4 command from @loopback/cli.

Installation

To use this package, you'll need to install @loopback/rest.

npm i @loopback/rest

Basic Use

Here's a basic "Hello World" application using @loopback/rest:

import {RestApplication, RestServer} from '@loopback/rest';

const app = new RestApplication();
app.handler(({request, response}, sequence) => {
  sequence.send(response, 'hello world');
});

(async function start() {
  await app.start();

  const server = await app.getServer(RestServer);
  const port = await server.get('rest.port');
  console.log(`Server is running at http://127.0.0.1:${port}`);
})();
