Angular just turbocharged its compiler by rewriting it in Rust.

The Angular team has launched a beta for a major compiler rewrite, called the Angular Preprocessor (ngp). To stay compatible with the recently released TypeScript 7.0, which removed a critical API, they rebuilt the compiler's analysis stage using the Rust-based Oxc toolchain. This decouples Angular's compilation process from TypeScript's own APIs, allowing for more flexible and faster tooling.

Initial benchmarks show massive improvements: cold builds are now 2-3x faster, and memory consumption was cut in half on a large project, dropping from 2.8 GB to 1.4 GB. For developers, this means significantly quicker build times and lower resource usage, especially for large codebases. The move to Rust signals a major performance-focused evolution for the Angular framework.
