Basic Routing

HTTP methods

Fastify exposes fastify.get(), fastify.post(), fastify.put(), fastify.delete(), fastify.patch(), and fastify.head() for each HTTP verb.

RESTful resource routes

Typical CRUD patterns map to standard HTTP verbs.

// List all
fastify.get('/items', async () => []);

// Create one
fastify.post('/items', async (req, reply) => {
  return { id: 1, created: true };
});

// Read one
fastify.get('/items/:id', async (req) => {
  return { id: req.params.id };
});

// Update one
fastify.put('/items/:id', async (req) => {
  return { id: req.params.id, updated: true };
});

// Delete one
fastify.delete('/items/:id', async (req, reply) => {
  return reply.status(204).send();
});

Quick check

Quick check: Which HTTP method is used to partially update a resource?

• PUT
• POST
• DELETE
• PATCH

Shorthand versus route()

fastify.get(path, handler) is shorthand. Use fastify.route({ method, url, schema, handler }) when one route needs several methods or lots of options.
