Angular Incremental Compilation: Faster Rebuilds
Angular's incremental compilation avoids full rebuilds by tracking changes, making performance proportional to what you changed, not the whole app. It speeds up development by reusing analysis and skipping file generation for unchanged code.
Angular's incremental compilation engine (`ngtsc`) makes rebuilds faster by tying performance to the number of changed files, not the whole app's size. It reuses information from the prior build, like class analysis, to avoid redundant work. This is key for large apps, as `ngtsc` can skip the expensive step of emitting JavaScript for unchanged files. The footgun is assuming only direct imports matter; indirect semantic changes, like altering a component's selector, can force rebuilds in other components that use it.
