fastifyaxios

Fastify Axios instance plugin; with this you can share many Axios instances in every part of your server.

This plugin supports typescript.

Under the hood the official Axios lib is used, the options that you pass to register will be passed to the Axios client. The axios is v1.3.2

You can provide in the options:

• config: axios request configuration - the prop name declare in the option is required
• client: a axios instance created by your self - the prop name declare in the option is required
• nothing

By default when register this plugin atomatically creates a axios client default in Fastify Instance.

Install

npm i fastifyaxios

Usage

Add it to your project with register and you are done!

const fastify = require('fastify')()

fastify.register(require('fastifyaxios'), {})

fastify.get('/fact', async function (req, reply) {
  const response = await this.axios({
    method: 'get',
    url: 'https://catfact.ninja/fact'
  })

  return response.data
})

fastify.listen({ port: 3000 }, (err) => {
  if (err) throw err
})

You may also supply config and name in options to register instance of axios in your fastify server:

const fastify = require('fastify')()

fastify.register(require('fastifyaxios'), {
  name: 'ninja',
  config: {
    baseURL: 'https://catfact.ninja'
  }
})

fastify.get('/fact', async function (req, reply) {
  const response = await this.axios.ninja.get('/fact')
  return response.data
})

fastify.listen({ port: 3000 }, (err) => {
  if (err) throw err
})

You may also supply a pre-started instance of axios:

const fastify = require('fastify')()
const axios = require('axios')

fastify.register(require('fastifyaxios'), {
  name: 'ninja',
  client: axios.create({
    baseURL: 'https://catfact.ninja'
  })
})

fastify.get('/fact', async function (req, reply) {
  const response = await this.axios.ninja.get('/fact')
  return response.data
})

fastify.listen({ port: 3000 }, (err) => {
  if (err) throw err
})

Notes:

• option name is required to supply a pre-started instance or axios cofig (as the code examples above. It set name like 'ninja')

Reference

This plugin decorates the fastify instance with a axios API. See more about Axios API.

The plugin options has the following properties:

• name is the name of axios intance
• client is the AxiosInstance
• config is the AxiosRequestConfig

The client can also be directly supply from a existent axios client.

A name option can be used in order to create multiple axios instances.

const fastify = require('fastify')()
const axios = require('axios')

fastify
  .register(require('fastifyaxios'), {
    name: 'ninja',
    client: axios.create({
      baseURL: 'https://catfact.ninja'
    })
  })
  .register(require('fastifyaxios'), {
    name: 'public',
    client: axios.create({
      baseURL: 'https://api.publicapis.org'
    })
  })

fastify.get('/', async function (req, reply) {
  const [response1, response2] = await Promise.all([
    fastify.axios.ninja.get('/fact'),
    fastify.axios.public.get('/categories')
  ])

  return {
    response1: response1.data,
    response2: response2.data
  }
})

fastify.listen({ port: 3000 }, (err) => {
  if (err) throw err
})

You can separate in different files to organize your project with multiple axios clients to set interceptors handlers and any other configuration more complex that you application need.
