Summary

  • Medusa 2.17.1 → 2.22.1 (all @medusajs/*, @medusajs/ui 4.2.8, @lambdacurry/medusa-product-reviews 1.4.0). Switched workflow-engine-redis to the non-deprecated redisUrl option.
  • React Router 7.18.1 → 8.5.0. Migrated meta / useMatches() from data to loaderData and dropped react-router-dom.
  • Tooling: React 19.3.1, Vite 8.3.5, TypeScript 6.0.3, Biome 2.6.3 (config migrated, build output ignored), Turbo 2.11.10 (incl. Dockerfiles), Yarn 4.18.1, Playwright 1.64.1.
  • Replaced @sentry/remix with @sentry/react-router.
  • Bumped Stripe JS/React, react-hook-form, @hookform/resolvers, remix-hook-form, @lambdacurry/forms, zod, lru-cache, dotenv, and others.
  • Removed ~30 unused storefront deps (remix, an unconfigured jest/eslint 8 toolchain, Stripe server SDK, zustand, react-player, etc.). Replaced lodash.omit/pick/isequal with lodash/*.
  • TS 6 changes: removed deprecated baseUrl, added explicit types.
  • e2e runner now uses the port from E2E_STOREFRONT_URL instead of a hardcoded 3000.
  • Updated .cursor rules that taught patterns that break on React Router v8.

Intentionally held back

  • TypeScript 7: removes the JS compiler API that medusa build loads, so we're on 6.0.3.
  • react-drag-drop-files 3: crashes at SSR module load (styled-components interop), so it's on 2.4.0.
  • Tailwind 4: a real config/CSS migration, left for a follow-up (on 3.4.19).
  • ESLint 10: @medusajs/eslint-plugin only supports ESLint 8–9.

Known peer warnings

  • Medusa admin declares React 18. The repo already forced React 19 via resolutions, and the admin works in testing.
  • @lambdacurry/forms pins its peer remix-hook-form to 7.1.0, and we're on 7.3.0. No issues seen.

Verification

  • yarn install --immutable, yarn typecheck, yarn build, yarn lint
  • Fresh DB: db:create, migrate, sync, seed, add-user
  • yarn e2e Playwright smoke passes
  • Production storefront build (react-router-serve): home and PDP render, hydrate without errors, add to cart works
  • Medusa admin: logged in and loaded the product list
  • docker build for both apps/medusa and apps/storefront; storefront container boots and passes its health check
  • Not verified: Stripe payment at checkout. With fake keys Stripe rejects payment-intent creation, so this needs a run with real test keys.

Summary by CodeRabbit

  • Updates

    • Updated the storefront and supporting services to newer React Router, React, and Medusa versions.

  • Improvements

    • End-to-end test runs now use the port specified in the storefront URL, or default to port 3000.
    • Updated setup guidance to reflect current React Router conventions.

Walkthrough

The pull request updates shared tooling and application dependencies, migrates storefront code and guidance to React Router v8, changes Medusa configuration, and makes E2E startup use the port in the storefront URL when present.

Changes

Framework and Toolchain Updates

Layer / File(s) Summary
Shared toolchain and source organization
.yarnrc.yml, package.json, biome.json, apps/*/Dockerfile, apps/storefront/app/components/*, apps/storefront/app/routes/*, apps/storefront/libs/util/*, apps/e2e/playwright.config.ts, apps/medusa/src/scripts/*
Yarn, root dependency versions, Biome configuration, and Docker build tool versions are updated. Import and export declarations are reorganized across storefront files; the Medusa seed imports and review-response type are reformatted.
Storefront React Router migration
apps/storefront/package.json, apps/storefront/tsconfig.json, apps/storefront/app/entry.*.tsx, apps/storefront/app/root.tsx, apps/storefront/app/hooks/*, apps/storefront/libs/util/*, .cursor/README.md, .cursor/rules/*
Storefront dependencies and type configuration are updated. Sentry uses its React Router integration, and route data access uses loaderData. Storefront guidance and examples target React Router v8.
Medusa dependencies and configuration
apps/medusa/package.json, apps/medusa/tsconfig.json, apps/medusa/medusa-config.ts, apps/medusa/integration-tests/http/health.spec.ts
Medusa and related package versions are updated. The Redis workflow-engine option uses redisUrl; compiler types are specified, and the health-test runner no longer sets inApp.
E2E storefront port selection
apps/e2e/package.json, apps/e2e/scripts/run-e2e.ts
The E2E script starts the storefront on the port parsed from E2E_STOREFRONT_URL, or on port 3000 when the URL has no explicit port.

P2 Badge Honor the storefront URL's implicit port

When E2E_STOREFRONT_URL is an HTTP(S) URL without an explicit port, URL.port is empty, so this starts the storefront on port 3000 while the health check still targets the protocol default (80 or 443). For example, E2E_STOREFRONT_URL=http://127.0.0.1 causes every E2E run to time out despite the server running; derive the fallback from the URL protocol or ensure the health-check URL uses the selected port.

Fixed in 376cb90. When the URL has no explicit port, the fallback is now the protocol default (443 for https, 80 otherwise), so the dev server and the health check use the same port.

Allow install scripts only for required dependencies.

enableScripts: true runs third-party postinstall scripts throughout the dependency tree. Yarn 4.18 otherwise disables those scripts by default. If a dependency is compromised, an install can execute its script on developer and build machines. Keep the default and approve the packages that require scripts through dependenciesMeta.

Fixed in 376cb90. I removed the override, so install scripts stay disabled by default. The packages that list scripts (esbuild, @swc/core, @parcel/watcher, msgpackr-extract, unrs-resolver, protobufjs, @medusajs/telemetry) all ship prebuilt binaries or only run informational scripts. With scripts disabled, I re-verified typecheck, build, the DB migrate and seed, the e2e smoke test, and both Docker builds, so I didn't add any dependenciesMeta allowances.

Comment thread .yarnrc.yml Resolved
yarn set version wrote overrides that disabled Yarn 4.18's install-script
block, package age gate, and git repository allowlist. None are needed:
the packages listing build scripts all ship prebuilt binaries.
