Angular 6 CLI -> how to make ng build build project + libraries

Question

So the question is pretty basic but I can\'t find it.

I created a new app through ng new my-project, followed by a ng g library my-library.

Answer 1

"build-all": "for PROJ in lib1 lib ''; do ng build $PROJ --prod || break; done"

• The '' provides an empty string to the loop, building the top-level project
• The || break stops the for loop once a library build fails

OR the follow works if

• Build system has jq
• None of your libraries have dependencies on each-other
  • This blindly builds over a list of projects found in angular.json
• Use scoped packages for your libraries
  • Why would you not?!
  • See next bullet's reason
• Top-level project is not scoped
  • Normally my top-level is a demo project, never published, so never scoped
  • Reason for this is jq always returns @ prefixed keys first in the array to loop over

"build-all": "for PROJ in $(cat angular.json | jq -r '.projects | keys[]'); do ng build $PROJ --prod; done"

At some point I want to look into building up a dependency tree based on the package.json(s) found in each project and sort the projects to build based on that. Just not a high priority over up-keeping a hard-coded list from the first suggestion :)
