Exclude Apps in affected scripts by tags from nx.json

Currently the only way to exclude apps and libs from being processed by the affected scripts, is by their names. It would be useful, if we could exclude apps and libs in the affected scripts by their tags which can be defined in nx.json

For example having the following nx.json

....
    "booking": {
      "tags": ["booking"]
    },
    "error-page": {
      "tags": ["error-page"]
    },
    "my-nanosite": {
      "tags": ["my-nanosite", "nanosites"]
    },
    "my-other-nanosite": {
      "tags": ["my-other-nanosite", "nanosites"]
    },
...

and running npm run affected:apps -- --base=origin/develop --exclude="tags:nanosites" or something similar 😃 only apps should printed out, which are affected by changes and do not have the nanosites tag. It should also be possible to pass a list of tags to be excluded. This would save us a lot of headaches, because we have more than 50 nanosites and adding them by name in the exclude part is tedious and error prone.

I know the nx.json is used for linting, but could that purpose be extended?

Hi,

I saw there is a pullrequest for .nxignore --> PR #1585

However it only works for the workspace-lint command and not the affected commands

Can it be added in? I see that its added in the core/file-utils.ts in the function allFilesInDir

However thats only use in the workspace-lint as i observed.

Can we add the ignore machanism for the affected as well?

From what I observe there are several places this mechanism can be coded in, if someone would guide with me it would be great.

1. We either add a project level check with tags/flags at these functions

• getTouchedProjects,
• getImplicitlyTouchedProjects,
• getImplicitlyTouchedProjectsByJsonChanges,
• getTouchedProjectsInNxJson,
• getTouchedProjectsInWorkspaceJson

1. Or we can go directly for the files using glob pattern in .nxignore

• Either in shared.parseFiles after the git command are run
• Or add directly into the file-utils.calculateFileChanges

I like the

add directly into the file-utils.calculateFileChanges

option the most. Please advise 😄, If so can i work on it and open a PR?
