Defined in:

lib/lilac/cli/build/template_ast_cache.rb

Overview

Memoizes parsed component template ASTs by component name. The same .lil shape often appears on many pages; the parse step is not free and the parsed result is immutable, so caching once per build keeps multi-page builds linear in components rather than pages × components.

Shared by Builder (when emitting the :bundle delivery file) and PageCompiler (per-page injection). Both read through fetch; writes happen lazily on miss.
