What is the meaning of NPM?
npm is two things: first and foremost, it is an online repository for the publishing of open-source Node.js projects; second, it is a command-line utility for interacting with said repository that aids in package installation, version management, and dependency management. A plethora of Node.js libraries and applications are published on npm, and many more are added every day.
What is Axios and how to use it?

What does Axios package do?
Axios is a Promise-based HTTP client for JavaScript which can be used in your front-end application and in your Node. js backend. By using Axios it's easy to send asynchronous HTTP request to REST endpoints and perform CRUD operations.
What is Axios in React?
In ReactJS, Axios is a library that serves to create HTTP requests that are present externally. It is evident from the fact that we may sometimes in React applications need to get data from the external source. It is quite difficult to fetch such data so that they can be normally shown on the website.
Is Axios a REST API?
A: They are two completely different thing. I see REST API as a form of standard for building your service. Whereas Axios. js is just a JavaScript library for you to make HTTP calls to an external service.
What is the use of Axios in node JS?
Axios allows us to make HTTP requests from both the browser and Node. js applications. It allows us to make both GET and POST requests which are the most used HTTP methods.
What does Axios stand for?
"Axios!" (Greek ἄξιος, "worthy of", "deserving of", "suitable") is an acclamation adopted by the early Syriac Orthodox Church, Eastern Orthodox church and Byzantine Eastern Catholic churches and made by the faithful at the ordination of bishops, priests and deacons.
How do I use Axios API?
First, you import React and Axios so that both can be used in the component. Then you hook into the componentDidMount lifecycle hook and perform a GET request. You use axios. get(url) with a URL from an API endpoint to get a promise which returns a response object.
Is Axios better than fetch?
Without question, some developers prefer Axios over built-in APIs for its ease of use. But many overestimate the need for such a library. The fetch() API is perfectly capable of reproducing the key features of Axios, and it has the added advantage of being readily available in all modern browsers.
Can I use Axios in vanilla JS?
Axios is similar to the fetch API and it can be used in plain JavaScript as well as in modern JavaScript frameworks like React, Angular, and Vue.
How to install axios?
Installing Axios is easy and only requires two steps: 1 Install Axios#N#To install with yarn:#N#$ yarn add axios#N#Install yarn#N#To install with npm:#N#$ npm install axios –save#N#Download node (which includes npm executable)#N#Using CDN: 2 After downloading, on top of the JS file that you plan to use Axios on, add the line:#N#import axios from ‘axios’;#N#Use: step by step by instructions on how to use it#N#Performing a GET request#N#axios.get (' http://api.fightpoverty.online/api/city?page=2’)#N#.then (function (response) {#N#// handle success#N#console.log (response);#N#})#N#.catch (function (error) {#N#// handle error#N#console.log (error);#N#})#N#.then (function () {#N#// always executed#N#});
What are the benefits of Axios?
Some other benefits of Axios include: Transformers: allow performing transforms on data before request is made or after response is received. Interceptors: allow you to alter the request or response entirely (headers as well). also perform async operations before request is made or before Promise settles.
What are some alternatives to Axios?
Some other alternatives to Axios include the fetch () method in Javascript or jQuery AJAX.With fetch there’s two steps to get JSON data, the first is to make the call, and the second is to call the .json () method on that response. For example, one query method that used Axios that my group used is shown below.
Does Axios need to be passed to json?
As you can see, with Axios, you don’t need to pass the results of the http request to the .json () method; it just gives you the data you’re looking for after get (). Axios is a lot easier to follow and read than the fetch () method or a request with jQuery. One of the backend members of my group had prior experience using Axios in one ...
Can you use Axios for HTTP?
You can also use Axios for POST requests if you would like your application to store user input/data in your own server. In other words, almost any dynamic website that displays data from different sources needs some way to make HTTP requests, and Axios is one of the most popular ways to do so.
What it does
In a nutshell, Axios is a Javascript library used to make HTTP requests from node.js or XMLHttpRequests from the browser that also supports the ES6 Promise API. Great, so from that we gather it does something that we can already do and that has recently been made significantly better… So why bother?
What it aims to improve: .fetch ()
Fetch uses a two-step process when dealing with JSON data; after making an initial request you’ll then need to call the .json () method on the response in order to receive the actual data object. If I were to have a fetch request to get back an object of relevant drivers for my carpool sourcing app, I might have something like the following:
Better error handling
There’s some extra work we need to put in on our end (again, it could be argued that this is just a matter of syntax memorization) for the desired result when it comes to properly logging response errors with .fetch (). MDN explains:
Installing Axios
Grabbing new libraries is easy as pie these days (Mmm.. rhubarb), I prefer npm. In the root of your project folder open terminal, run npm install axios and you’re all set. Now to achieve the same fetch request we performed earlier, we can invoke axios.get () in place of our fetch method like so:
What is Axios transform?
Axios allows you to provide functions to transform the outgoing or incoming data, in the form of two configuration options you can set when making a request: transformRe quest and transformResponse. Both properties are arrays, allowing you to chain multiple functions that the data will be passed through.
What is Axios interceptor?
While transforms let you modify outgoing and incoming data, Axios also allows you to add functions called interceptors. Like transforms, these functions can be attached to fire when a request is made, or when a response is received.
Can Axios be used in Node.js?
Currently, Fetch has no support for doing this. Lastly, Axios can be used in both the browser and Node.js. This facilitates sharing JavaScript code between the browser and the back end or doing server-side rendering of your front-end apps.
Is Axios a third party library?
Being a popular library, Axios benefits from an ecosystem of third-party libraries that extend its functionality. From interceptors to testing adaptors to loggers, there’s quite a variety available. Here are a few that I think you may find useful:
1. What is Axios?
Axios is a promise-based HTTP client for Node.js and the browser. Sending asynchronous HTTP queries to REST endpoints and performing CRUD operations is simple using Axios. It can be used directly in JavaScript or in conjunction with a library like Vue or React.
2. Why Axios?
If you are using JavaScript, it provides, XMLHttpRequest, a built-in interface for handling HTTP requests. Sending requests with this interface, on the other hand, is a bit of a pain and necessitates writing a lot of code.
4. Sending HTTP Request with Axios
Sending HTTP requests with Axios is as simple as giving an object to the axios () function that contains all of the configuration options and data.
6. Axios Response Objects
When we send an HTTP request to a remote server, we get a response with specific information from that server. Axios may be used to retrieve this response.
7. Post Request
The response is provided as a promise because Axios is promise-based. To obtain the response and catch any errors, we must utilize the then () and catch () functions.
8. Get Request
Axios can make a GET request to “get” data from a server. The axios.get () method is used to make an HTTP get request.
9. Multiple Concurrent Request
Axios allows us to send multiple requests at the same time. To do so, we'll use the Promise.all () function to pass an array of request calls.
