Verified dependency versions October 4 2026

Next.js 16.3.8 and React/React DOM 19.3.0 are the current stable releases, verified against npm. All application routes use App Router under src/app, including the server API route handlers and dynamic order/payment pages. The typed Next.js configuration enables typed routes; type checking generates route types first. Lucide, Playwright, React types, Prettier, tsx, CrewAI, FastAPI and Uvicorn are already current. Node type definitions are updated to 26.6.4.

TypeScript is upgraded to the newest version supported by the lint parser, 6.0.3. TypeScript 7.0.2 is available but the parser declares support below 6.1. ESLint remains at the newest compatible 9.x version, 9.39.5: Next.js’s React/import lint plugins exclude ESLint 10.12.0. These compatibility pins preserve the complete lint checks. Node.js 24.21.0 is the latest 24.x LTS runtime and supports the latest npm 12.2.0.

All tracked application code, tests, Next.js configuration and ESLint configuration use .ts or .tsx. The lint command uses Node’s native TypeScript configuration loader. CSS styles, the HTML research document and the separate Python CrewAI service retain their original file types. GitHub’s language summary can temporarily show the old default-branch statistics while it recalculates them.
