npm install
npm run seed

Or both via npm run dev (requires concurrently, installed with the workspace).

npm run seed
npm start

Serves the built SPA and API on port 3456 (override with PORT).

Question bank

Questions live in data/questions/ — one JSON file per topic (~50 questions each). Each question includes a documentationUrl pointing to the matching official docs (Symfony 8.0, PHP, Twig, RFC, …). An optional code field can show a short excerpt under the stem (PHP, YAML, Twig, …), as in certification-style understanding questions.

Important: the question bank was generated with AI. Answers and explanations may contain mistakes or outdated details. Treat them as a study aid, not as an official source of truth.

The bank is meant to evolve: corrections, rewrites, and new questions are welcome. Edit or add entries (stable id), then run npm run seed.

Estimated Advanced / Expert levels
