Parcel 2: the Automagical Bundler
summary
Parcel 2 is a ground-up rewrite that claims more than 2x faster builds by using caching and CPU-parallel workers, and it proves scale with memory improvements that let it handle large monorepos. It replaces ad-hoc plugins with a typed transformer/optimizer plugin pipeline, introduces targets for modern+legacy bundles and stable caches so caches survive restarts, adds name-pipeline and query-param imports, and ships improved scope-hoisting and code-splitting that work in production.
