Why use axios-queue-js?

axios-queue-js is a lightweight wrapper of axios that enables you to make requests using a queue. In simple words, it improves significantly the performance of your requests, once no request is made unless there's an open slot for it. This lib works for both web and node environments and can be easily placed in codebases that already use axios to handle requests, even if they are using a custom client.

Performance of axios with axios-queue-js

All the following results were colleted by doing requests to a localhost server and all the scripts used the default configs for axios-queue-js.

The following chart represents the performance of a node script trying to do 1k sequential requests using nothing but axios.

After almost 2min of execution, axios triggered an error that terminated the script, that was able to do and finish only 209 requests.

Now you can see the results of the same test after using axios along with axios-queue-js in the script.

It's worth mentioning that all the 1k requests were successfully made in only 6 seconds. That is about 5x more requests being made in only 5% of the time.

For the next chart we repreated the previous testing, but this time with 100k requests.

As you can see below, axios-queue-js was able to make axios handle about 478x more requests in only 3x more time than axios did alone.

Usage

You can add axios-queue-js in your project by running a npm install --save axios axios-queue-js or yarn add axios axios-queue-js in your project.

After that, you can use axios-queue-js as shown in the following examples.

// By using module imports
import axios from 'axios-queue-js';

axios.get('https://endpoint.test.net').then((response) => {
  console.log('Hey look, I am getting a response using axios-queue-js :D');
});

axios.post('https://endpoint.test.net', {}).then((response) => {
  console.log('Hey look, I am posting something and getting a response using axios-queue-js :D');
});

// By using commonjs
const { default: axios } = require('axios-queue-js');

axios.get('https://endpoint.test.net').then((response) => {
  console.log('Hey look, I am getting a response using axios-queue-js :D');
});

axios.post('https://endpoint.test.net', {}).then((response) => {
  console.log('Hey look, I am posting something and getting a response using axios-queue-js :D');
});

Customizing

If you want to customize the queue length or even use an external axios client to handle the requests, you can create your own AxiosQueueManager instance and use it as you will. Eg.:

// By using module imports
import axios from 'axios';
import { AxiosQueueManager } from 'axios-queue-js';

const axiosQueueClient = new AxiosQueueManager({ queueSize: 10, client: axios.create() });

axiosQueueClient.get('https://endpoint.test.net').then((response) => {
  console.log('Hey look, I am getting a response using axios-queue-js :D');
});

// By using commonjs
const axios = require('axios')
const { AxiosQueueManager } = require('axios-queue-js');

const axiosQueueClient = new AxiosQueueManager({ queueSize: 10, client: axios.create() });

axiosQueueClient.get('https://endpoint.test.net').then((response) => {
  console.log('Hey look, I am getting a response using axios-queue-js :D');
});

Following is a table with all the possible properties that you can set when creating your own AxiosQueueManager instance.

Key	Optional	Default Value	Type	Description
queueSize	True	10	Number	Represents the queue's maximum size
client	True	axios.default	AxiosInstance	Custom axios instance that will be used under the hood to handle the requests
