How to get github token using username and password

Send A POST request to /authorizations With headers

Content-Type: application/json Accept: application/json Authorization: Basic base64encode(<username>:<password>)

But remember to take Two factor Authentication in mind https://developer.github.com/v3/auth/#working-with-two-factor-authentication

Here You will receive a token which can be used for further request

Here is the code to use GitHub Basic Authentication in JavaScript

let username = "*******";
    let password = "******";
    let auth = "Basic " + new Buffer(username + ":" + password).toString("base64");
    
    var options = {
        host: 'api.github.com',
        path: '/search/repositories?q=google%20maps%20api',
        method: 'GET',
        headers: {
                'user-agent': 'node.js',
                "Authorization": auth
                 }
                 };
    var request = https.request(options, function (res) {
                  }));
