fastify-static

Plugin for serving static files as fast as possible.

Install

npm install --save fastify-static

Usage

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

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

fastify.get('/another/path', function (req, reply) {
  reply.sendFile('myHtml.html') // serving path.join(__dirname, 'public', 'myHtml.html') directly
})

Options

root (required)

The absolute path of the directory that contains the files to serve. The file to serve will be determined by combining req.url with the provided root directory.

prefix

Default: '/'

A URL path prefix used to create a virtual mount path for the static directory.

schemaHide

Default: true

A flag that define if the fastify route hide-schema attribute is hidden or not

setHeaders

Default: undefined

A function to set custom headers on the response. Alterations to the headers must be done synchronously. The function is called as fn(res, path, stat), where the arguments are:

• res The response object.
• path The path of the file that is being sent.
• stat The stat object of the file that is being sent.

send Options

The following options are also supported and will be passed directly to the send module:

• acceptRanges
• cacheControl
• dotfiles
• etag
• extensions
• immutable
• index
• lastModified
• maxAge

Disabling reply decorator

The reply object is decorated with a sendFile function by default. If you want to disable this, pass the option { decorateReply: false }. If fastify-static is registers to multiple prefixes in the same route only one can initialize reply decorators.

Handling 404s

If a request matches the URL prefix but a file cannot be found for the request, Fastify's 404 handler will be called. You can set a custom 404 handler with fastify.setNotFoundHandler().

Handling Errors

If an error occurs while trying to send a file, the error will be passed to Fastify's error handler. You can set a custom error handler with fastify.setErrorHandler().

Payload stream.filename

If you need to access the filename inside the onSend hook, you can use payload.filename.

fastify.addHook('onSend', function (req, reply, payload, next) {
  console.log(payload.filename)
  next()
})
