config

@lakeql/config is the composition layer. It loads your lakeql.config.ts, validates the data-source definitions against the registered adapters, and composes a runtime that owns the live data-source instances.

Install it:

pnpm add @lakeql/config

If you scaffolded with create-app, @lakeql/config is already installed.

Three functions span the lifecycle:

• defineConfig — author the config file with full type inference.
• loadConfig — load it and resolve it into a neutral project object. Per-source validation runs in defineConfig and the adapter factory, not here.
• createLakeQLRuntime — compose the runtime from the loaded config, the adapter factories, and an auth resolver.

This section covers the runtime config contract and the full API reference.
