support running multiple lint tasks within the same process

[dmitry-stepanenko]

The problem that I faced is related to linting with "parserOptions": { "project": ["tsconfig.*?.json"] } defined in eslintrc.json. When this is done, the time it takes to run a particular task may increase in up to 10 times. It's totally not acceptable in workspaces with 1000+ libs as we have, because linting can take 3-4 hours of billable time per run.

As a workaround, I have defined a separate eslint config alongside with base eslintrc.json in the workspace root and extracted there all rules that require type checking.

This allows me to run expensive linting only for changed files both on the CI and as a pre-commit check.

• on CI this is done through this script that is invoked as node scripts/ci-format-check.mjs --base=${{ env.NX_BASE }} --head=${{ env.NX_HEAD }}, which determines the diff between revisions and lints them
• same as a pre-commit check using lint-staged

Overall this is a functional solution and I'm totally fine with it, however it is definitely not something that each team should go through when face similar problems.

Unfortunately I don't have a good vision on how this can be integrated into nx story while maintaining it's philosophy. Do you think it's reasonable? Or it might be enough to provide the recipe to do something similar to what I have described above?
