调研方向

buildserve 命令使用的持久缓存入手,并将其与 .angular/cache 现有的 ng cache clean 入口进行比较。定义如何配置和测量 cli.cache.maxSize,然后验证在超过配置的上限后,最近最少使用的条目会被逐出。

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.
