Is it safe to delete Angular CLI cache?
Build results the Angular CLI saves in a project so later builds and tests run faster.
Safe
Its owner recreates it by itself when it needs it, and nothing you made is lost.
~/
- Never inside ~/
Library
What it is
The Angular CLI saves the results of build steps in the .angular/cache folder of each workspace and reuses them in later builds and test runs. It creates the cache again the next time you build. The cache grows as you work and stays behind in projects you no longer work on.
If it's removed
The next build or test run of the project is slower.
How it's removed
Moved to the Trash, where you can restore it.
The free analyzer finds it and explains it. Removing it is Pro, after a review sheet that lists every move and command. It starts checked in the Cleanup checklist, except inside Documents or Desktop.
