SIGNALS VS QUERY-BASED COMPILERS

Summary from the TLDR Dev newsletter

Modern query-based compilers are an efficient architecture for interactive development environments, moving beyond traditional linear processing pipelines to support features like Language Server Protocols (LSPs). These compilers operate on a demand-driven "pull-only" model, executing only the necessary queries and using caching to rapidly answer specific requests without processing unrelated files. This is different from UI Signals, which use a "push-pull" system to actively propagate changes and ensure instant, glitch-free synchronization across a user interface.
