What is @fastify/cors?

@fastify/cors is a Fastify plugin that enables Cross-Origin Resource Sharing (CORS) for your Fastify application. It allows you to configure how your server handles cross-origin requests, which is essential for enabling web applications to interact with resources from different origins.

What are @fastify/cors's main functionalities?

Enable CORS with default settings

This code demonstrates how to enable CORS with the default settings in a Fastify application. By registering the @fastify/cors plugin without any options, it allows all cross-origin requests.

const fastify = require('fastify')();
const cors = require('@fastify/cors');

fastify.register(cors);

fastify.get('/', (request, reply) => {
  reply.send({ hello: 'world' });
});

fastify.listen(3000, err => {
  if (err) throw err;
  console.log('Server listening on http://localhost:3000');
});

Enable CORS with specific origin

This code demonstrates how to enable CORS for a specific origin. By passing an options object with the 'origin' property set to 'https://example.com', only requests from this origin will be allowed.

const fastify = require('fastify')();
const cors = require('@fastify/cors');

fastify.register(cors, { origin: 'https://example.com' });

fastify.get('/', (request, reply) => {
  reply.send({ hello: 'world' });
});

fastify.listen(3000, err => {
  if (err) throw err;
  console.log('Server listening on http://localhost:3000');
});

Enable CORS with multiple origins

This code demonstrates how to enable CORS for multiple origins. By passing an array of origins to the 'origin' property, requests from any of these origins will be allowed.

const fastify = require('fastify')();
const cors = require('@fastify/cors');

fastify.register(cors, { origin: ['https://example.com', 'https://another-example.com'] });

fastify.get('/', (request, reply) => {
  reply.send({ hello: 'world' });
});

fastify.listen(3000, err => {
  if (err) throw err;
  console.log('Server listening on http://localhost:3000');
});

Enable CORS with custom headers

This code demonstrates how to enable CORS with custom headers. By passing an options object with the 'allowedHeaders' property, you can specify which headers are allowed in cross-origin requests.

const fastify = require('fastify')();
const cors = require('@fastify/cors');

fastify.register(cors, { allowedHeaders: ['Content-Type', 'Authorization'] });

fastify.get('/', (request, reply) => {
  reply.send({ hello: 'world' });
});

fastify.listen(3000, err => {
  if (err) throw err;
  console.log('Server listening on http://localhost:3000');
});
