How to push select files to heroku with pipeline

[ashinzekene]

I have two folders in my bitbucket repository but I want to deploy the contents of only the back-end folder to heroku. I tried this

script:
- cp ./front-end/dist ./back-end -r
- cp ./front-end/index.html ./back-end
- rm -rf front-end
- mv back-end/* .
- ls -Al
- rm back-end -rf
- git push https://heroku:$HEROKU_API_KEY@git.heroku.com/$HEROKU_APP_NAME.git HEAD

But I still get this error 

+ git push https://heroku:$HEROKU_API_KEY@git.heroku.com/$HEROKU_APP_NAME.git HEAD
remote: Compressing source files... done.
remote: Building source:
remote:
remote: -----> App not compatible with buildpack: https://buildpack-registry.s3.amazonaws.com/buildpacks/heroku/nodejs.tgz
remote: Node.js: package.json not found in application root
remote:
remote: More info: https://devcenter.heroku.com/articles/buildpacks#detection-failure
remote:
remote: ! Push failed

But the ls -Al logs

How do I make this work?

Hi Ekene,

I'm not particularly familiar with how Heroku deployments work. However, this StackOverflow question seems to be the exact same question that you have: https://stackoverflow.com/questions/7539382/how-can-i-deploy-push-only-a-subdirectory-of-my-git-repo-to-heroku

Does that help at all?

Thanks,

Phil
