SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Upgrading the SWC Rust crates that Rspack depends on is a multi-step, error-prone process: versions must stay aligned across the workspace, generated code must be regenerated, upstream changelogs must be analyzed for breaking changes, and a properly formatted PR must be opened. This Skill automates that entire workflow end to end.

Core Features & Use Cases

  • Aligned dependency upgrade: Queries crates.io for the latest stable swc_core release, resolves compatible versions for all in-scope SWC crates, and updates Cargo.toml and Cargo.lock without touching excluded swc_experimental_* crates.
  • Tag-to-tag changelog analysis: Compares swc_core@OLD...NEW tags via the GitHub compare API, classifies breaking changes, features, performance improvements, and fixes, and correlates verified fixes with open Rspack issues.
  • Validation and PR automation: Regenerates workspace code with cargo codegen, validates with pnpm run build:binding:dev, then commits, pushes, and opens a PR following the Rspack title and description conventions.
  • Use Case: A maintainer asks to bump swc_core to the latest release; the Skill updates the pins, adapts any breaking API changes, documents the relevant upstream changes, and opens a ready-to-review PR.

Frequently Asked Questions about bump-rspack-swc

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I upgrade swc_core in the Rspack repository?▼

Update the SWC dependency block in the root Cargo.toml to the latest stable swc_core release, refresh Cargo.lock, run cargo codegen to regenerate workspace version code, and validate with pnpm run build:binding:dev. This Skill performs all of these steps and opens the PR.

How do I analyze SWC changelog changes between two versions?▼

Compare the exact tags swc_core@OLD_VERSION...swc_core@NEW_VERSION using the GitHub compare API, then classify commits into breaking changes, features, performance improvements, and bug fixes relevant to Rspack integration surfaces.

Does the SWC upgrade also bump swc_experimental crates?▼

No. All swc_experimental_* crates are treated as independent and out of scope. The workflow never queries, bumps, or changes their manifest or lockfile versions.

What validation runs after upgrading SWC dependencies?▼

Only pnpm run build:binding:dev is run as the validation command. Tests, lint, and other checks are skipped unless the user explicitly requests them.

When should a SWC bump PR mention upstream bug fixes?▼

Only when an upstream fix matches a verified Rspack issue's failure mode and is validated when practical. Weak or unverified connections are omitted rather than listed as related.
