OAuth 1.0a Twitter API Authentication on NodeJS

When I was trying to implement the Messages Authentication header for Twitter, I wondered how I could achieve it as there are no available modules that can easily fit.

In this article, I’m going to share its implementation with you from scratch by using the basic node module

Prerequisites for this article

• Should have knowledge about basics of NodeJS and RESTful API
• Have auth credentials for API which are
  - oauth_consumer_key
  - oauth_consumer_secret
  - oauth_token
  - oauth_token_secret

You can find more information on
https://developer.twitter.com/en/docs/authentication/oauth-1-0a

If you all this above, we are good to go.

Here How’s it work

In this article, I am going to use examples for direct messages on Twitter POST API. You can extend this wherever needed

First, we need to require everything needed for implementation, I am using here request module for HTTP calls, you can replace it with any other HTTP call package

const request = require("request");
const uuidv4 = require('uuid/v4');
const crypto = require('crypto');
