Deploy to Heroku

Heroku deployment works best when the app and environment assumptions are explicit

Deploying to Heroku is not just a publish click. The useful work is making sure your Wappler project, environment variables, services, and runtime expectations match a platform where the app is packaged and started from a controlled environment. Once that contract is clear, the publish step becomes much more predictable.

Environment clarity

Know which values and services the app expects at runtime.

Target fit

Match the project's runtime and services to what Heroku will provide.

Predictable deployment

Reduce surprise by verifying assumptions before publishing.

Confirm the app runs cleanly before you think about the Heroku target.

Know which secrets, databases, or add-ons must exist in the deployment environment.

Treat deployment as an environment contract, not a one-off upload.

A practical Heroku checklist is runtime, environment, services, then publish

The most useful sequence is to verify the runtime and target settings, check environment variables and any backing services, then publish and inspect the result with deployment feedback. This keeps platform issues separate from app issues.

Verify the runtime target and project settings that matter for the deployed app.

Set or confirm the environment values the app needs on Heroku.

Use deployment feedback and logs to validate the first release instead of assuming success.
