Bigcommerce Catalyst Catalyst

Release Catalyst Patch (single-package isolation)

The Changesets GitHub Action picks one mode per push to canary: if any unconsumed changesets exist, it opens/refreshes the Version Packages PR and does not publish. That's why we publish locally — we keep the other changesets in .changeset/ so the Version Packages PR still tracks them, but we ship just the one we want now.

Execute stages in order. Pause for user input where indicated. Never execute the changeset publish command yourself — provide it to the user to run.

Stage 0: Confirm scope

Identify the changeset to release and the target package + version.

ls .changeset/
git log --oneline -10                       # find the PR/commit that added the changeset
cat .changeset/<changeset-file>.md          # confirm the package + bump type
npm view <package> version dist-tags        # confirm current published state

Confirm with the user:

• Which .changeset/*.md file is being released
• The target package and the resulting version (e.g., 1.0.2 → 1.0.3)
• That all other changesets in .changeset/ should remain queued for the next regular release

If the package has notes in the Package-specific notes section below, review them before continuing.

Stage 1: Branch + quarantine

Work on a release branch so the workflow doesn't trigger mid-flow.

git switch canary && git pull
git switch -c release/<package>-<new-version>

Move the other changesets outside the repo. A subdirectory inside .changeset/ gets parsed as a malformed changeset by the CLI and crashes changeset version:

mkdir -p /tmp/changeset-hold
mv .changeset/<other-1>.md .changeset/<other-2>.md ... /tmp/changeset-hold/
ls .changeset/   # should leave only config.json + the one changeset to release

Stage 2: Run changeset version

Requires GITHUB_TOKEN because the repo uses @changesets/changelog-github. The gh CLI token works.

pnpm install --frozen-lockfile
GITHUB_TOKEN=$(gh auth token) pnpm changeset version

Restore the held changesets immediately:

mv /tmp/changeset-hold/*.md .changeset/
rmdir /tmp/changeset-hold

Verify the diff:

git status
git diff packages/<package>/package.json packages/<package>/CHANGELOG.md

Expect: bumped package.json, new CHANGELOG entry, deleted only the one changeset. The other changesets should be back in .changeset/ and untouched.

Stage 3: Build

Run the root build. Turborepo handles env passthrough from .env.local via the pipeline config, so package builds get the variables they need without manual sourcing.

pnpm build

If a package has build-time secrets that must be present, see the Package-specific notes section for verification steps.

Stage 4: Commit

git add -A
git commit -m "Version Packages (\`canary\`)"

Match the message format the changesets bot uses, since this is a manual stand-in for it.

Stage 5: Hand the publish command to the user

Do not run changeset publish from the agent. Publishing to npm is a destructive, externally-visible action that should be performed by the user.

Have the user confirm they're logged in, then run the publish themselves. The CLI will prompt them interactively for the npm OTP.

npm whoami                       # expect their npm username
pnpm exec changeset publish      # prompts for OTP interactively

changeset publish is per-package version-aware: it only publishes packages whose local package.json is ahead of npm. Since only one package was bumped, only it ships. It also creates a local git tag like @bigcommerce/<package>@<version>.

Wait for the user to confirm the publish completed before continuing.

Stage 6: Verify npm state

npm view <package> version
npm view <package> dist-tags

latest should point to the new version. If it doesn't (rare — only happens if publishConfig.tag is set), advise the user to fix with:

npm dist-tag add <package>@<version> latest

Stage 7: Fast-forward canary and push

This requires a direct push to the protected default branch. Pause and ask for explicit user authorization before pushing — the user's "never push directly to main/master/production" rule guards against this even though the changesets bot does the same thing during normal releases.

git switch canary
git fetch origin canary
git log --oneline origin/canary..canary    # should be 1 ahead
git log --oneline canary..origin/canary    # should be 0 behind
git merge --ff-only release/<package>-<new-version>

If you're 1 ahead and 0 behind, default git push rejects non-fast-forward updates, which gives the same safety as --ff-only on the push side. Apple's git build (≤2.50.x) does not accept --ff-only as a push flag — git push origin canary is correct here.

If a hook blocks the agent push, hand these commands to the user:

git push origin canary
git push origin "@bigcommerce/<package>@<new-version>"

Stage 8: Create the GitHub release manually

CI runs changeset publish after the canary push, finds the version already on npm, and no-ops. Because the action only creates GitHub releases for packages it actually publishes, no release is created automatically in this flow. Make it manually.

Extract the new CHANGELOG section (everything after the ## <version> heading up to the next ## heading) into a notes file. Then:

gh release create "@bigcommerce/<package>@<new-version>" \
  --repo bigcommerce/catalyst \
  --title "@bigcommerce/<package>@<new-version>" \
  --notes-file /tmp/release-notes.md

Match the body format of prior releases — just the ### Patch Changes / ### Minor Changes heading and the bullets, no version heading at the top. Compare against an existing release:

gh release view "@bigcommerce/catalyst-core@<some-prior-version>" --repo bigcommerce/catalyst --json body

Stage 9: Final validation

git fetch origin canary
git log --oneline origin/canary -3                                              # version commit on canary
git ls-remote --tags origin "@bigcommerce/<package>@<new-version>"              # tag on origin
gh release view "@bigcommerce/<package>@<new-version>" --repo bigcommerce/catalyst --json tagName,isDraft,isPrerelease
gh run list --workflow=changesets-release.yml --limit 1                         # CI run succeeded
gh pr list --search "Version Packages (canary)" --state open --json number,headRefName,updatedAt   # Version Packages PR refreshed
git fetch origin changeset-release/canary
git show --stat origin/changeset-release/canary | head -20                      # confirm only the other changesets remain
npm view <package> version dist-tags

Report:

• Published version + dist-tag
• Canary commit SHA
• Tag pushed
• GitHub release URL
• Confirmation that the Version Packages PR now contains only the other changesets — the released one has been dropped from its scope.

Stage 10: Cleanup

git branch -d release/<package>-<new-version>

Package-specific notes

@bigcommerce/create-catalyst

The CLI build (tsup via the package's tsup.config.ts) inlines CLI_SEGMENT_WRITE_KEY at build time, falling back to the placeholder 'not-a-valid-segment-write-key' if the env var is missing. After Stage 3, verify the real key was embedded:

grep -c "not-a-valid-segment-write-key" packages/create-catalyst/dist/index.js
# expect: 0

If 1, the env var wasn't loaded. Confirm CLI_SEGMENT_WRITE_KEY exists in .env.local, and that the turbo pipeline for build declares it under env or passThroughEnv in turbo.json. Re-run pnpm build after fixing.
