BitBucket Pipeline to Heroku npm run build script

[blubberbo]

I am not 100% on how pipelines work, but I think I understand at least the basics. Following the guide here: https://confluence.atlassian.com/bitbucket/deploy-to-heroku-872013667.html, it believe it deploys the code that has been committed to the branch, correct? If I have an npm script that I run to build for production, such as "npm run build", do I need to run that before I commit my code to the BitBucket branch for the pipeline to deploy it correctly? Or can I commit the code right from being developed and have the pipeline run "npm run build" without having to commit the newly built files to the BitBucket repo?

Does that make sense?

Thank you!

Hi Sydney,

The standard and recommended approach is to only commit the source code to the repository and build all other files within your pipeline.

So if my pipeline executes "npm run build", will those newly created files then be pushed to Heroku, or will they need to be "committed" first?
