Making an API call in NodeJS

There are many ways available to send HTTP request or make a REST API call during acceptance testing:

1. HTTP - The standard library

• default HTTP module in the standard Node.js library.
• No need to install any external dependency.
• It is NOT very user-friendly compared to other solutions.
• It does not parse the response data manually.
• It does not support HTTPS by default, so you need to require the https module instead if required.

2. Request - Simplified HTTP client

• An easy to use library that deals with HTTP requests
• For promise handling, use Bluebird or switch to request-promise library

3. Codecept REST API Helper

• This helper use unirest to perform requests.
• Provides easy to understand DSL

4. Unirest

• Lightweight HTTP Request Client library
• Provides a cookie jar to store multiple cookies

5. Axios

• This is a promise based HTTP client for the browser and node.js

• Make XMLHttpRequests from the browser

• Make http requests from node.js

• Supports the Promise API

• Intercept request and response

• Transform request and response data

• Cancel requests

• Automatic transforms for JSON data

• Client-side support for protecting against XSRF

• The request contains the following information:

  data: {},status, statusText, headers, config (the config that was provided to axios with request), request.

6. node-fetch

• A light-weight module that brings window.fetch to node.js
• Stay consistent with window.fetch API.
• Use native promise, but allow substituting it with other popular promise libraries like Bluebird
• Use native Node streams for body, on both request and response.
• Useful extensions such as timeout, redirect limit, response size limit, explicit errors for troubleshooting.

7. request-promise

• Simplified HTTP request client 'request' with Promise support. Powered by Bluebird.
• request-promise wraps around request so everything that works with request also works with request-promise

8. SuperAgent

• Makes AJAX requests from the browser
• Make http requests from node.js
• Provides a function query() to add parameters to the request.
• It parses the JSON response automatically.

Why use Promise Libraries while Node.js has added native support for promises?
