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.

loadCapabilities()​

protected loadCapabilities(): void

Defined in: packages/core/src/services/service.ts:270

Load capabilities from webda.module.json metadata into _compiledCapabilities.

Called during resolve after dependency injection. Reads the service's type name from parameters, looks it up in the application's module metadata (moddas or beans section), and populates _compiledCapabilities with an empty object for each declared capability name.

Fails silently if the application is not available (e.g., in unit tests where services are instantiated without a full application context).

Returns​

void

Example​

// If webda.module.json contains:
// { "moddas": { "MyApp/HawkService": { "capabilities": ["request-filter", "cors-filter"] } } }
// Then after resolve(), this.getCapabilities() returns:
// { "request-filter": {}, "cors-filter": {} }
