https://developer.twitter.com/en/docsand create an account if you don't have one. - Go to 
My Applicationsand create new Application. - Fill in Application details.
 - Go to 
Keys and tokenstab. (There you will find application keys and tokens) - Create 
.envfile in the root of project directory and populate the values like in example below: 
PORT=<port>
CONSUMER_KEY=<consumer_key>
CONSUMER_SECRET=<consumer_secret>
ACCESS_TOKEN=<access_token>
ACCESS_TOKEN_SECRET=<access_token_secret>

npm start.
