Om Auto Upgrade 0.4.10 To 0.5.0

auto-upgrade-0.4.10-to-0.5.0

Apply the Open Mercato 0.4.10 → 0.5.0 dependency-upgrade codemods to this standalone application.

Context for this window:

• 0.5.0 is the biggest Open Mercato release so far
• it includes more than 250 fixes and improvements after the Hackathon in Sopot
• several important dependency upgrades landed in the same release, which is why dedicated upgrade notes and this companion skill were added

Scope

This skill operates on the current standalone app created with create-mercato-app or any downstream app that depends on @open-mercato/*.

It applies the mechanical parts of the upgrade. It does NOT bump the @open-mercato/* dependencies themselves — that is still the user's pinning decision. Run this skill after the user bumps their dependencies and runs yarn install.

When to use

• User says: "upgrade Open Mercato from 0.4.10 to 0.5.0", "bump open-mercato to 0.5.0", "migrate my code for the new open-mercato version", "apply the 0.5.0 upgrade notes".
• After the user changes their @open-mercato/* pins from 0.4.10 to 0.5.0 and runs yarn install.

When NOT to use

• The user is on a version older than 0.4.10 or newer than 0.4.10 targeting 0.5.0. Use or create the matching auto-upgrade-<from>-<to> skill instead.
• The user wants to upgrade deferred majors such as MikroORM 6 → 7, TypeScript 5 → 6, or Awilix 12 → 13.

Arguments

• --path <dir> (optional) — root of the standalone app. Default: current working directory.
• --dry-run (optional) — print planned edits without writing.
• --skip <id[,id...]> (optional) — skip specific codemods by id.
• --only <id[,id...]> (optional) — run only specific codemods.

Codemods

Workflow

0. Gate checks

bashCopy code
test -f package.json || { echo "Not a Node project — aborting"; exit 1; }
grep -q '"@open-mercato/' package.json || {
  echo "No @open-mercato/* dependency found — is this the right repo?"; exit 1;
}

grep -q '"@open-mercato/core": "\^\\?0\\.5\\.0"' package.json || \
  echo "⚠️  @open-mercato/core is not pinned to 0.5.0 — run this skill after bumping."

If the version check warns, ask the user to confirm before editing.

1. Detection scan

For each codemod id in the table above, run its detection grep or AST query and build a PlannedEdits list: { codemodId, filePath, before, after }.

Skip codemods with no matches. Print the plan before editing:

textCopy code
Codemod                            Matches  Files
meilisearch-class-rename           3        src/search/client.ts, src/search/admin.tsx
lucide-brand-icons                 2        src/components/SocialLinks.tsx
cron-parser-api                    1        src/jobs/reminder.ts

Ask the user to confirm, unless the user explicitly requested an automatic run.

2. Apply codemods

Rules:

• One minimal edit per file where practical. Do not rewrite whole files when a targeted edit is enough.
• Preserve indentation, surrounding comments, and import ordering.
• For AST-shaped codemods such as react-markdown-classname-wrap and stripe-api-version-type, read the file first and then make the smallest correct edit.
• For lucide-brand-icons, add a one-line follow-up comment above the substituted usage:

tsxCopy code
// TODO(open-mercato 0.5.0): lucide-react v1 removed brand icons; Briefcase is a generic substitute

3. Post-edit verification

Run in this order and stop at the first failure:

bashCopy code
yarn tsc --noEmit 2>&1 | tail -40

If tsc fails with errors clearly caused by a codemod, roll back that codemod and add it to the manual follow-up list. Do not auto-revert unrelated pre-existing errors.

If the app has a Jest config, run:

bashCopy code
yarn test 2>&1 | tail -20

If tests fail with meilisearch ESM import errors, make sure the meilisearch-jest-esm codemod applied.

4. Report

Print a final summary with:

• applied codemods
• skipped codemods
• manual review items
• validation results
• exact edited file paths

Suggested close-out structure:

textCopy code
Upgrade 0.4.10 → 0.5.0 complete.

Applied:
  ✅ meilisearch-class-rename
  ✅ cron-parser-api
  ✅ lucide-brand-icons — review the TODO comments

Needs human review:
  ⚠️ src/components/SocialLinks.tsx — confirm the generic icon replacement.

Validation:
  yarn tsc --noEmit ✅
  yarn test ✅

5. Out of scope

Flag these for manual handling instead of editing them automatically:

• recharts 2 → 3
• rate-limiter-flexible 9 → 11
• framer-motion 11 → 12
• esbuild 0.25 → 0.28
• eslint 9 → 10
• AI SDK major migrations
• deferred majors such as MikroORM 7, TypeScript 6, or Awilix 13

Rules

• Never edit node_modules/, .yarn/, dist/, .next/, or build/.
• Never regenerate yarn.lock; dependency installation belongs to the user's yarn install step.
• Every codemod must be idempotent.
• If a codemod is not unambiguous, skip it and add it to manual follow-up.
• Always include the exact list of edited files in the final report.
