Preparing for SuperJS v1.0 RC

Preparing for SuperJS v1.0 RC

SuperJS v1.0 is the first stable release of our hand-written compiler, CLI, LSP, docs site, and ecosystem wrappers. We have not tagged 1.0.0-rc.1 yet — this post explains where we are and what comes next.

What merged

  • Language spec freeze — specs/language.md with CI grammar gate
  • Docs — 20-lesson tour, migration guide, API reference, compat matrix, perf benchmarks
  • Playground — server-side /api/run, Workers mode, Cloudflare Worker scaffold
  • Interop — 30 @superjs/types-* wrappers
  • Governance — STABILITY, Dependabot, CodeQL, threat model v1.0 review

Cut from v1.0

  • DAP debugger — deferred to post-1.0
  • LLVM native backend — v2.0 milestone

Path to RC

  1. Playground Worker production deploy (maintainer)
  2. Beta program — three teams on 1.0.0-rc.X
  3. Bug bash + external security review
  4. RC tags (rc.1 → rc.2 → GA)

Follow progress: v1.0 RC status.

Try it today

The playground and docs are live on superjs.org. Published npm packages remain 0.1.x until the RC cycle begins.

npm install -g @superjsorg/cli
superjs init
superjs build

We will announce 1.0.0-rc.1 on this blog when beta onboarding opens.
