simonprickett / twitter-follower-getter

A Google Cloud function to get the number of Twitter followers for a specified handle.

twitter-follower-getter

Google Cloud Function that returns the number of followers a given handle has, or -1 if it can't get them. Example response:

{
    "followers": 1001
}

Example code to call this, using JavaScript fetch API:

const myHeaders = new Headers();
myHeaders.append('x-api-key', '<api key>');

const requestOptions = {
  method: 'GET',
  headers: myHeaders,
  redirect: 'follow'
};

fetch('https://<cloud function url>/getFollowers?handle=<twitter handle>', requestOptions)
  .then(response => response.text())
  .then(result => console.log(result))
  .catch(error => console.log('error', error));

Where:

• <api key> is the value of the API_KEY environment variable for your deployed funtion (see below).
• <cloud function url> is the Google Cloud URL for your deployed function.
• <twitter handle> is the Twitter handle you want to get the number of followers for, for example mine is simon_prickett.

When deploying to Google Cloud Functions, add the following environment variable:

• API_KEY - set to whatever value you want to use, then provide that value in the x-api-key header when calling the function.
• TWITTER_BEARER_TOKEN - set to a Twitter API bearer token for the Twitter API v2.
