How to use Nrwl nx tools (for angular) with bitbucket pipelines to utilize nx affected?

[Saurabh Kumar]

I am having an existing angular project using Nrwl nx workspace. For CI I am using bitbucket pipelines. nx has very helpful feature of nx affected which allows running targets like test/lint/build etc based only on the changes. Also in bitbucket pipelines, I am till now using parallel steps for running tests on multiple libraries in parallel. e.g from bitbucket-pipelines.yml files

- parallel:
      # parallel execution
      - step: *test-lib1
      - step: *test-lib2
      - step: *test-lib3

Now what I am trying to do is to run tests on affected libraries in the pipeline - using below command to get the list of affected libraries

npx nx print-affected --target=test --base=master --select="tasks.target.project"

Any help in this direction is appreciated.
