# TypeScript runtime conformance example This retained SQLite example is generated from `model.xml` and verifies the minimum runtime-owned contract: explicit `ensureSchema`, Create, Update, Delete, typed Q, E loaded/null/not-loaded semantics, Checker rejection before SQL, and optimistic-version isolation for different entity types that share a numeric ID. ```bash npm install npm run build npm start ``` The generated workspace targets `@teaql/teaql` 0.1.17. Regenerate it with the local code generator's `typescript-app-console` target before checking a new generator/runtime combination.
