:zap: fast http framework for rust |
An efficient server implies a lower cost of the infrastructure, a better responsiveness under load and happy users. How can you efficiently handle the resources of your server, knowing that you are serving the highest number of requests as possible, without sacrificing security validations and handy development?
Enter Fastify. Fastify is a web framework highly focused on providing the best developer experience with the least overhead and a powerful plugin architecture. It is inspired by Hapi and Express and as far as we know, it is one of the fastest web frameworks in town.
The main
branch refers to the Fastify v4
release. Check out the
v3.x
branch for v3
.
Create a folder and make it your current working directory:
mkdir my-app
cd my-app
Generate a fastify project with npm init
:
npm init fastify
Install dependencies:
npm i
To start the app in dev mode:
npm run dev
For production mode:
npm start
Under the hood npm init
downloads and runs Fastify
Create, which in turn uses the
generate functionality of Fastify CLI.
To install Fastify in an existing project as a dependency:
Install with npm:
npm i fastify
Install with yarn:
yarn add fastify
// Require the framework and instantiate it
// ESM
import Fastify from 'fastify'
const fastify = Fastify({
logger: true
})
// CommonJs
const fastify = require('fastify')({
logger: true
})
// Declare a route
fastify.get('/', (request, reply) => {
reply.send({ hello: 'world' })
})
// Run the server!
fastify.listen({ port: 3000 }, (err, address) => {
if (err) throw err
// Server is now listening on ${address}
})
with async-await:
// ESM
import Fastify from 'fastify'
const fastify = Fastify({
logger: true
})
// CommonJs
const fastify = require('fastify')({
logger: true
})
fastify.get('/', async (request, reply) => {
reply.type('application/json').code(200)
return { hello: 'world' }
})
fastify.listen({ port: 3000 }, (err, address) => {
if (err) throw err
// Server is now listening on ${address}
})

.
Code for Fastify's v1.x is in branch 1.x
, so all Fastify 1.x related
changes should be based on branch 1.x
. In a similar way, all Fastify
v2.x related changes should be based on branch 2.x
.
Note
.listen
binds to the local host,localhost
, interface by default (127.0.0.1
or::1
, depending on the operating system configuration). If you are running Fastify in a container (Docker, GCP, etc.), you may need to bind to0.0.0.0
. Be careful when deciding to listen on all interfaces; it comes with inherent security risks. See the documentation for more information.

Benchmarks taken using fastify/benchmarks. This is a synthetic, "hello world" benchmark that aims to evaluate the framework overhead. The overhead that each framework has on your application depends on your application, you should always benchmark if performance matters to you.
