Package description

What is fastify-static?

The fastify-static package is a Fastify plugin that allows you to serve static files, such as HTML, CSS, JavaScript, images, and other assets, from a directory. It is designed to be highly performant and easy to use, leveraging Fastify's speed and low overhead.

What are fastify-static's main functionalities?

Serve Static Files

This feature allows you to serve static files from a specified directory. In this example, files from the 'public' directory are served with the URL prefix '/public/'.

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

fastify.register(require('fastify-static'), {
  root: path.join(__dirname, 'public'),
  prefix: '/public/', // optional: default is '/'
});

fastify.listen(3000, err => {
  if (err) throw err;
  console.log('Server listening on http://localhost:3000');
});

Serve Single Page Applications (SPA)

This feature is useful for serving Single Page Applications (SPA). When a route is not found, it serves the 'index.html' file, allowing the client-side router to handle the navigation.

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

fastify.register(require('fastify-static'), {
  root: path.join(__dirname, 'public'),
  wildcard: false
});

fastify.setNotFoundHandler((request, reply) => {
  reply.sendFile('index.html');
});

fastify.listen(3000, err => {
  if (err) throw err;
  console.log('Server listening on http://localhost:3000');
});

Serve Files with Custom Headers

This feature allows you to set custom headers for the served files. In this example, a custom header 'X-Custom-Header' is added to all responses.

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

fastify.register(require('fastify-static'), {
  root: path.join(__dirname, 'public'),
  setHeaders: (res, path, stat) => {
    res.setHeader('X-Custom-Header', 'fastify-static');
  }
});

fastify.listen(3000, err => {
  if (err) throw err;
  console.log('Server listening on http://localhost:3000');
});
