v2.9.0

Minor Changes

• ffc7d53: Add ApiRunner class in src/api-runner.ts that encapsulates the creation and lifecycle management of all Counterfact sub-systems (Registry, ContextRegistry, ScenarioRegistry, ScenarioFileGenerator, CodeGenerator, Dispatcher, Transpiler, ModuleLoader, and OpenApiDocument) for a single API specification.

  Each sub-system is exposed as a public property. The class provides four composite methods — generate(), load(), watch(), and stopWatching() — that coordinate across multiple sub-systems based on the supplied configuration. Use the static async ApiRunner.create(config) factory method to construct an instance.

  counterfact() in app.ts now uses ApiRunner internally.

• a6bb5bc: Add support for multiple API specifications via ApiRunner.

  • ApiRunner.create(config, group?) now accepts an optional group string (default "") that places generated code in a subdirectory of config.basePath.
  • ApiRunner exposes group as a public readonly property and subdirectory as a computed getter (returns "" when group is empty, or "/${group}").
  • CodeGenerator receives config.basePath + runner.subdirectory so each spec's generated files land in the right subdirectory.
  • createKoaApp now accepts runners: ApiRunner[] (an array) instead of a single runner. It loops over all runners to mount per-spec OpenAPI document, Swagger UI, Admin API, and route-dispatching middleware.
  • counterfact() accepts an optional specs: SpecConfig[] second argument (each entry has source, prefix, and group). When omitted, a single spec is derived from config.openApiPath and config.prefix for full backward compatibility. The REPL is configured using the first spec's runner.
  • The spec key in counterfact.yaml can now be a single {source, prefix, group} object or an array of such objects to configure multiple APIs from the config file.

• 26e00eb: Add openApiPath and prefix as public readonly properties on ApiRunner.

  Refactor createKoaApp to accept runner: ApiRunner (providing the dispatcher, registry, context registry, OpenAPI path, and route prefix) instead of a config: Config monolith plus separate sub-system refs. All other config fields used by createKoaApp are now explicit named arguments, laying the groundwork for passing multiple runners to createKoaApp in the future.

Patch Changes

• aa23b79: Support .scenario <group> <path> in multi-API REPL sessions while preserving single-runner syntax.
• d0dff90: Warn and skip loading context modules when they fail to import, including syntax errors in _.context files.
• 75938e3: Prefer OpenAPI route paths for REPL tab completion and refactor completer lookups into focused helpers.
• 7a8c0b6: Move MSW (Mock Service Worker) code out of app.ts into a dedicated src/msw.ts module. The MockRequest type, handleMswRequest, and createMswHandlers are still re-exported from app.ts for backward compatibility. Tests for these functions have been moved to test/msw.test.ts.
• 4894f18: Organized Koa middleware into a dedicated src/server/web-server/ directory. Each middleware constructor now takes its path prefix as the first argument, making createKoaApp easier to read at a glance. openapiMiddleware simplified to handle a single path only.
• 3aa8416: Expose grouped REPL context and routes for multi-API runners, and require non-empty unique group names when configuring multiple APIs.
• b270516: Move CLI logic from bin/counterfact.js into src/cli/ as TypeScript modules
• a3d16ab: Update REPL .scenario tab completion to suggest groups first in multi-API mode and group-scoped scenarios after selection.
