nx-eslint-slow-test

There are two projects in here: plain & custom-eslint-slow.

This repo exists to show that when generating a custom eslint @nrwl/linter:workspace-rule that is just the generated example where it significantly adds to the lint time as we increase the amount of libraries/apps involved.

The plain application uses nest as its base workspace generator and has 9 generated libs.
The custom-eslint-slow uses nest as its base workspace generator and has 9 generated libs and a custom eslint @nrwl/linter:workspace-rule

When running the command time npx nx run-many --target=lint --all --skip-nx-cache in each project we can see how the timings change due to the custom eslint @nrwl/linter:workspace-rule. When running against a single lib or app it is insignificant (1-2 sec) but when running against many targets we start to see how that adds up (10s vs 27s).
