Requirements:

• Node 12.9.0+ because it uses Promise.allSettled()
• Twitter dev keys (more below)
• A good attitude

Unfollow Stale accounts

You'll need a developer keys from twitter → https://developer.twitter.com/en/apps - this might be hard because they don't just hand out keys anymore. You need to apply if you don't have a legacy app from before the crackdown.

Put your keys in a file called .env like this:

username=wesbos
consumer_key=wowowowo
consumer_secret=yayayaay
access_token=teeheee
access_token_secret=errrrnngggg

Set the cutLimit variable in index.js and then run it with npm start.

Some things to note

Rate limits on twitter are real. If you follow more than 3000 people, you'll hit the 200 x 15 rate limit.

You could fix this by npm install waait

then:

const wait = require('waait');
// ... then in your getListOfPeopleYouFollow function, add this:
if (data.next_cursor) {
    // wait 1 min
    await wait(60000);
    getListOfPeopleYouFollow(data.next_cursor);
