Step 5. Connect your application to Redis Enterprise Cloud#

For this demonstration, we will be using a Sample Rate Limiting application

Clone the repository#

git clone https://github.com/redis-developer/basic-redis-rate-limiting-demo-nodejs

Run the below CLI to have a functioning Git repository that contains a simple application as well as a package.json file.

heroku create
Creating app... done, ⬢ rocky-lowlands-06306
https://rocky-lowlands-06306.herokuapp.com/ | https://git.heroku.com/rocky-lowlands-06306.git

Step 6. Setting up Environmental variable#

Go to Heroku dashboard, click "Settings" and set REDIS_ENDPOINT_URI and REDIS_PASSWORD under the Config Vars. Refer to Step 1 for the reference.

heroku

You now have a functioning Git repository that contains a simple application as well as a package.json file, which is used by Node’s dependency manager.

Step 7. Deploy your code#

$ git push heroku

Wait for few seconds and you will see the below messages being displayed:
