fastify-axios

js-standard-style codecov

A plugin for Fastify that adds support for sending requests via axios, a promise based HTTP(s) client for node.js and browser.

Under the hood axios http client is used, the options passed to register will be used as the default arguments while creating the axios http client.

Install

npm install fastify-axios

Default usage

Just add it to the project generated via fastify-cli, create-fastify-app, or with register in you application as below.

You can access the axios instance via fastify.axios, which can be used to send HTTP(s) requests via methods GET, POST, PUT, DELETE etc. Here a simple example

'use strict'

module.exports = async function (fastify, opts) {
  fastify.register(require('fastify-axios'))

  // request via axios.get
  const { data, status } = await fastify.axios.get('https://nodejs.org/en/')
  console.log('body size: %d', data.length)
  console.log('status: %d', status)
}

Alternatively you can specify default args to your axios instance. You can take a look at the default parameters here https://github.com/axios/axios:

'use strict'

module.exports = async function (fastify, opts) {
  fastify.register(require('fastify-axios'), {
    baseURL: 'https://nodejs.org'
  })

  // request via axios.get to https://nodejs.org/en/
  const { data, status } = await fastify.axios.get('/en/')
  console.log('body size: %d', data.length)
  console.log('status: %d', status)
}

Add more clients

It's possibile to add more than one axios client to your fastify instance. Here's how:

'use strict'

module.exports = async function (fastify, opts) {
  fastify.register(require('fastify-axios'), {
    clients: {
      v1: {
        baseURL: 'https://v1.api.com',
        headers: {
          'Authorization': 'Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJxyz'
        }
      },
      v2: {
        baseURL: 'https://v2.api.com',
        headers: {
          'Authorization': 'Bearer UtOkO3UI9lPY1h3h9ygTn8pD0Va2pFDcWCNbSKlf2HE'
        }
      }
    }
  })

  // Now you can use the apis in the following way
  const { dataV1, statusV1 } = await fastify.axios.v1.get('/ping')
  const { dataV2, statusV2 } = await fastify.axios.v2.get('/ping')

  // do something with dataV1 and dataV2
}
