Step 1. Create Redis Cloud#

Create your free Redis Cloud account. Follow this link to create Redis Cloud subscription and database as shown below:

Save the database endpoint URL and password for future reference.

Step 2. Create a Heroku account#

If you are using Heroku for the first time, create your new Heroku account through this link

Step 3. Install Heroku CLI on your system#

Step 4. Login to Heroku#

Step 5. Connect your application to Redis Cloud#

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

Clone the repository#

Step 6. Setting up environment variables#

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

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#

Heroku generates a random name (in this case hidden-woodland-03996) for your app, or you can pass a parameter to specify your own app name. Now deploy your code:

Step 8. Accessing the application#

Open https://hidden-woodland-03996.herokuapp.com/ to see your application
