fastify-autoload

Require all plugins in a directory.

Install

npm i fastify fastify-autoload

Example

'use strict'

const Fastify = require('fastify')
const AutoLoad = require('fastify-autoload')

const fastify = Fastify()

fastify.register(AutoLoad, {
  dir: path.join(__dirname, 'foo')
})

fastify.listen(3000)

Custom configuration

Plugins in the loaded folder could add an autoPrefix property, so that a prefix is applied automatically when loaded with fastify-autoload:

module.exports = function (fastify, opts, next) {
  // when loaded with autoload, this will be exposed as /something
  fastify.get('/', (request, reply) => {
    reply.send({ hello: 'world' })
  })
}

// optional
module.exports.autoPrefix = '/something'

If you need to disable the auto loading for a specific plugin, add autoload = false property.

module.exports = function (fastify, opts, next) {
  // your plugin
}

// optional
module.exports.autoload = false

If you want to pass some custom options to the registered plugins via fastify-autoload, use the options key:

fastify.register(AutoLoad, {
  dir: path.join(__dirname, 'foo'),
  options: { foo: 'bar' }
})

Note that options will be passed to all loaded plugins.

You can set the prefix option in the options passed to all plugins to set them all default prefix. When plugins get passed prefix as a default option, the autoPrefix property gets appended to them. This means you can load all plugins in a folder with a default prefix.

// index.js
fastify.register(AutoLoad, {
  dir: path.join(__dirname, 'foo'),
  options: { prefix: '/defaultPrefix' }
})

// /foo/something.js
module.exports = function (fastify, opts, next) {
  // your plugin
}

// optional
module.exports.autoPrefix = '/something'

// routes can now be added to /defaultPrefix/something

If you have a plugin in the folder you don't want the default prefix applied to, you can add the prefixOverride key:

// index.js
fastify.register(AutoLoad, {
  dir: path.join(__dirname, 'foo'),
  options: { prefix: '/defaultPrefix' }
})

// /foo/something.js
module.exports = function (fastify, opts, next) {
  // your plugin
}

// optional
module.exports.prefixOverride = '/overriddenPrefix'

// routes can now be added to /overriddenPrefix

If you have a plugin in the folder you don't want the any prefix applied to, you can set prefixOverride = '':

// index.js
fastify.register(AutoLoad, {
  dir: path.join(__dirname, 'foo'),
  options: { prefix: '/defaultPrefix' }
})

// /foo/something.js
module.exports = function (fastify, opts, next) {
  // your plugin
}

// optional
module.exports.prefixOverride = ''

// routes can now be added without a prefix

If you have some files in the folder that you'd like autoload to skip you can set ignorePattern option to a regex. If that matches a file it will not load it.

// index.js
fastify.register(AutoLoad, {
  dir: path.join(__dirname, 'foo'),
  options: { prefix: '/defaultPrefix' }
  ignorePattern: /.*(test|spec).js/
})
