Rspack Release Pr

Workflow

1) Clean the worktree

Inspect the tree first:

git status --short
git diff --cached --quiet

If there are staged changes, stop.

If there are only unstaged tracked or untracked changes and the user explicitly authorized discarding them, clean them non-interactively:

git restore --worktree -- .
git clean -fd
git status --short

Proceed only when git status --short is empty.

2) Sync to the latest origin/main

git fetch origin --prune
git switch main 2>/dev/null || git switch -c main --track origin/main
git reset --hard origin/main
git status --short

The release branch should start from the exact current origin/main, not from an older local branch tip.

3) Reinstall dependencies

pnpm install

Run this before the version bump so the local release tooling and workspace dependencies are fresh.

4) Create the release branch

Use the current local date in YYYY-MM-DD format:

RELEASE_DATE="$(date +%F)"
BRANCH="chore/release-${RELEASE_DATE}"
git switch -c "$BRANCH"

Reuse the same RELEASE_DATE later in the PR body.

5) Bump the version

Choose the bump version from the user request:

• major, minor, or patch
• Default to patch when the user does not specify one
• If the user explicitly asks for alpha, beta, or rc, add --pre <tag>

Examples:

./x version patch
./x version minor
./x version patch --pre rc
./x version minor --pre beta

./x version ... already updates the published JavaScript package versions, updates the Rust workspace version through the release tooling, runs cargo codegen, and runs pnpm run format:js.

After the command finishes, read the authoritative versions from:

• JavaScript packages: packages/rspack/package.json
• Rust crates: [workspace.package].version in the root Cargo.toml

Example commands:

JS_VERSION="$(pnpm exec node -e 'const fs=require("node:fs"); console.log(JSON.parse(fs.readFileSync("packages/rspack/package.json","utf8")).version)')"
RUST_VERSION="$(pnpm --dir scripts exec node -e 'const fs=require("node:fs"); const TOML=require("@iarna/toml"); console.log(TOML.parse(fs.readFileSync("../Cargo.toml","utf8")).workspace.package.version)')"
printf 'JavaScript packages version: %s\nRust crates version: %s\n' "$JS_VERSION" "$RUST_VERSION"

Show both values to the user and wait for confirmation before continuing.

6) Commit, push, and open the PR

Once the user confirms the versions, prepare the release metadata:

RELEASE_OWNER="$(gh api user --jq .login 2>/dev/null || git config user.name)"

If RELEASE_OWNER is empty, ask the user for the value before creating the PR.

Stage and commit the version bump:

git add -A
git commit -m "chore(release): release ${JS_VERSION}"
git push -u origin "$BRANCH"

Create an English PR body with the required fields:

## Release Information

- Released By: <release_owner>
- Release Date: <release_date>
- JavaScript Packages Version: <js_version>
- Rust Crates Version: <rust_version>

Then open the PR:

cat >/tmp/rspack-release-pr-body.md <<EOF
## Release Information

- Released By: ${RELEASE_OWNER}
- Release Date: ${RELEASE_DATE}
- JavaScript Packages Version: ${JS_VERSION}
- Rust Crates Version: ${RUST_VERSION}
EOF

gh pr create \
  --base main \
  --head "$BRANCH" \
  --title "chore: release version ${JS_VERSION}" \
  --body-file /tmp/rspack-release-pr-body.md

Capture the PR number and URL immediately after creation:

PR_NUMBER="$(gh pr view --json number --jq '.number')"
PR_URL="$(gh pr view --json url --jq '.url')"

7) Trigger ecosystem-ci

The workflow file is .github/workflows/ecosystem-ci.yml and the workflow display name is Ecosystem CI.

Trigger it with the PR number:

DISPATCH_USER="$(gh api user --jq .login)"
PREV_ECOSYSTEM_CI_RUN_ID="$(gh run list \
  --workflow ecosystem-ci.yml \
  --event workflow_dispatch \
  --user "$DISPATCH_USER" \
  --limit 1 \
  --json databaseId \
  --jq '.[0].databaseId // ""')"

gh workflow run ecosystem-ci.yml --ref main \
  -f pr="$PR_NUMBER" \
  -f suite=- \
  -f suiteRefType=precoded \
  -f suiteRef=precoded

Then wait a few seconds and poll until a new workflow-dispatch run appears for this workflow:

sleep 5
while :; do
  RUN_ID="$(gh run list \
    --workflow ecosystem-ci.yml \
    --event workflow_dispatch \
    --user "$DISPATCH_USER" \
    --limit 1 \
    --json databaseId \
    --jq '.[0].databaseId // ""')"
  ECOSYSTEM_CI_URL="$(gh run list \
    --workflow ecosystem-ci.yml \
    --event workflow_dispatch \
    --user "$DISPATCH_USER" \
    --limit 1 \
    --json url \
    --jq '.[0].url // ""')"

  if [ -n "$RUN_ID" ] && [ "$RUN_ID" != "$PREV_ECOSYSTEM_CI_RUN_ID" ]; then
    break
  fi

  sleep 5
done

Do not report the previous latest run. Only report the first new workflow_dispatch run from DISPATCH_USER that appears after your dispatch for PR_NUMBER.

8) Report the result

End by telling the user:

• PR URL: <pr_url>
• Ecosystem CI URL: <ecosystem_ci_url>

Include the confirmed JavaScript and Rust version numbers again if that helps the handoff.

Common traps

• Do not keep local staged work mixed into the release PR.
• Do not skip the user confirmation step after ./x version ....
• Do not derive the PR title from template packages under packages/create-rspack/template-*; use the published version in packages/rspack/package.json.
• Do not forget that the Rust version is authoritative in the root Cargo.toml, even though ./x version updates many files.
• Do not stop at the workflow dispatch command. Always retrieve the PR URL and the workflow run URL before reporting completion.
