Future of RxJS
summary
Version 7 shrinks the library dramatically — it lands at 53% of v6 size after piecemeal refactors and typings overhaul — and tightens types but now requires TypeScript 4.2. A planned top‑level export removes deep imports, and removing long‑deprecated APIs in version 8 trims another ~10 KB. Roadmap focuses on ergonomics: better docs, a universal cancellation primitive (AbortSignal), interest in a pipeline operator and a small observable primitive. Development remains volunteer driven with tooling experiments and codemods to ease migration.
