How can I improve the scalability of my Node.js app on Heroku?

To improve scalability, consider using Heroku's dynos effectively, implementing load balancing, and optimizing your database connections.

What are dynos and how do they work?

Dynos are lightweight containers that run your applications on Heroku. You can scale your app by adding more dynos.

How do I monitor the performance of my app?

You can use Heroku's built-in metrics, or integrate third-party tools like New Relic or Datadog for detailed performance monitoring.

Are there any best practices for optimizing Node.js performance?

Yes, some best practices include using asynchronous programming, minimizing middleware, and caching responses where possible.
