Configuring CI Using GitLab and Nx
Below is an example of a GitLab pipeline setup for an Nx workspace only building and testing what is affected.

51 stage: build

53 script:
54 - npx nx affected --base=$NX_BASE --head=$NX_HEAD --target=build --parallel=3
55The build and test jobs implement the CI workflow using .distributed as template to keep CI configuration file more readable.
Distributed CI with Nx Cloud
In order to use distributed task execution, we need to start agents and set the NX_CLOUD_DISTRIBUTED_EXECUTION flag to true.
