Fastify/4/Expose Head Routes

Last update

Aug 19, 2024

This codemod makes exposeHeadRoutes true by default

🚦 Impact Level: Minimal

What Changed

Starting with v4, every GET route will create a sibling HEAD route. You can revert this behavior by setting exposeHeadRoutes: false in the server options.

Before

const fastify = require('fastify')();

fastify.get('/example', (request, reply) => {
    reply.send({ message: 'Hello, World!' });
});

fastify.listen(3000, () => {
    console.log('Server is running on http://localhost:3000');
});

After

const fastify = require('fastify')();

fastify.get('/example', (request, reply) => {
    reply.send({ message: 'Hello, World!' });
});
fastify.listen(3000, () => {
    console.log('Server is running on http://localhost:3000');
});
