Command
build, serve
Description
The Angular CLI persistent disk cache (.angular/cache) grows without bounds. On large projects, a single checkout accumulates tens of gigabytes of cached build artifacts. In our case, a single checkout reached 29 GB.
This was previously raised in #25116 and closed as not feasible with Webpack. Since Angular 17+, the build system uses esbuild, so the original constraint no longer applies.
Describe the solution you'd like
Add a configurable size cap (e.g., cli.cache.maxSize) with LRU eviction when the limit is reached. This is a common pattern in build tooling — Turborepo, Gradle, and most browsers' HTTP caches all implement bounded persistent caches.
Example configuration:
"cli": {
"cache": {
"enabled": true,
"maxSize": "2GB"
}
}When the cache exceeds maxSize, the oldest/least-recently-used entries are evicted.
Describe alternatives you've considered
- Periodically running
ng cache clean or manually deleting .angular/cache — works but is a manual maintenance burden, especially for developers unaware the cache is growing.
