Properties​

_compiledCapabilities​

protected _compiledCapabilities: Record<string, any> = {}

Defined in: packages/core/src/services/iservice.ts:58

Capabilities detected at compile-time from @WebdaCapability-tagged interfaces.

Populated during Service.resolve by reading the service's entry in webda.module.json. Each key is a capability name (e.g., "request-filter"), and the value is an empty object {} by default. Override getCapabilities to provide capability-specific configuration or to conditionally disable capabilities.

Iterable of initialized services to scan for filter capabilities

Returns​

void

Example​

// Called automatically by Core.init():
router.discoverFilters(Object.values(this.services));

// A service with "request-filter" capability is auto-registered:
