Running nested package.json commands

I am trying out digital ocean platform, have been using heroku; My project is a MEAN stack application. In heroku the build process worked like this; npm install the backend nodejs app; then that node app had a postinstall script that would run a required js script and also CD into my client directory and run the npm install for that directory, this client directory also had a post-install script to run ng build to build the angular repo for the nodejs to serve.

When I set up the repo to deploy to the DigitalOcean App Platform this nested npm install and commands do not seem to execute and build my frontend package.

I have been unable to find any questions or documents that reference this specific type of circumstance so I am hoping I am not asking an old question.

The essential idea would be to adjust your build command in the App specification to something like this:

  1. npm install && npm run build && cd client && npm install && npm run build

This command will make sure that your server-side dependencies are installed and built before it navigates to your client directory to do the same.

You can specify your build command while creating and configuring your app in the app specification settings. If you’ve already created your app, you can adjust the build command by re-deploying your app with the updated configuration. You can find more information about configuring your app here.

Please keep in mind that the above command is just an example and might need to be adjusted according to your app’s specific requirements.

Hope that this helps!
