# Basic Routing — Fastify

Source: https://www.geekswithgeeks.com/en/fastify/ff-basic-routing

> Define routes for HTTP verbs and resource patterns.

## 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.

```javascript
// 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();
});
```

**Quiz:** Which HTTP method is used to partially update a resource?

- [ ] PUT
- [x] PATCH
- [ ] POST

*Answer:* PATCH. PATCH is for partial updates; PUT replaces the entire resource.
