Description
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.

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.
Requirements
Node.js v10 LTS (10.16.0) or later.
Quick start
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 install
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.
Install
If installing in an existing project, then Fastify can be installed into the project as a dependency:
Install with npm:
npm i fastify --save
Install with yarn:
yarn add fastify
Example
// Require the framework and instantiate it
const fastify = require('fastify')({
logger: true
})
// Declare a route
fastify.get('/', (request, reply) => {
reply.send({ hello: 'world' })
})
// Run the server!
fastify.listen(3000, (err, address) => {
if (err) throw err
fastify.log.info(`server listening on ${address}`)
})
with async-await:
const fastify = require('fastify')({
logger: true
})
fastify.get('/', async (request, reply) => {
reply.type('application/json').code(200)
return { hello: 'world' }
})
fastify.listen(3000, (err, address) => {
if (err) throw err
fastify.log.info(`server listening on ${address}`)
})

Fastify v1.x and v2.x
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](./docs/Server.md#listen) for more information.
Core features
- Highly performant: as far as we know, Fastify is one of the fastest web frameworks in town, depending on the code complexity we can serve up to 76+ thousand requests per second.
- Extendible: Fastify is fully extensible via its hooks, plugins and decorators.
- Schema based: even if it is not mandatory we recommend to use JSON Schema to validate your routes and serialize your outputs, internally Fastify compiles the schema in a highly performant function.
- Logging: logs are extremely important but are costly; we chose the best logger to almost remove this cost, Pino!
- Developer friendly: the framework is built to be very expressive and help the developer in their daily use, without sacrificing performance and security.
