When are Heroku Libraries Useful?

Heroku libraries are especially beneficial in the following scenarios:

  • Rapid Prototyping: With their predesigned components and features, Heroku libraries can accelerate the development and prototyping of applications, enabling developers to quickly showcase a functional build.

  • Efficient Scaling: Heroku libraries can handle the process of scaling out an application across multiple dynos intelligently. This functionality is beneficial when there is a surge in app traffic or demands, allowing for efficient app scaling.

  • Improved Deployment Workflow: Heroku libraries, when used together with the platform's Git-based deployment system, can automate many mundane and error-prone tasks in the deployment process, leading to much more streamlined, efficient, and reliable deployments.

What Functionalities do Heroku Libraries Usually Have?

Typically, Heroku libraries come with the following key features:

  • Add-Ons Support: Heroku libraries often include support for various add-ons that provide additional features such as data stores, analytics, monitoring, and more.

  • Release Management: They commonly include efficient release management features, enabling developers to track the app's history, rollback to a previous version when necessary, and overall better handle project versioning.

  • Automatic System Administration: Heroku libraries are designed to handle a large part of system administration tasks automatically. This includes server configurations, health monitoring, failover, and more.

  • Environment Configuration: Almost all the important configurations in Heroku libraries are stored in the environment variables, making it easy to migrate and manage the application in different environments.

Gotchas/Pitfalls to Look Out For

Below are some potential pitfalls when using Heroku Libraries:

  • Dyno Sleeping: Free and hobby Heroku dynos go to sleep after 30 minutes of inactivity. Therefore, initial requests after an inactive period can lead to slow response times.

  • File System: Heroku's ephemeral file system is read-only with parts reset at least daily or whenever the dyno restarts. Any data saved locally in a dyno will be lost, so alternative storage solutions should be considered.

  • Database Size Limit: In Heroku, the free Postgres database has a row limit. If your application grows, you may need to switch to a paid plan.

  • Limited Availability of Free Tier: The free hours available for Heroku can sometimes be limited, which can lead to your application turning off towards the end of the month if you run out of free dyno hours.

Keep in mind that even though npm is the package manager for Node.js, Heroku supports several other programming languages (Python, Ruby, Java, etc.) and their associated package managers.
