Variable: CurrentUser

const CurrentUser: (…dataOrPipes) => ParameterDecorator

Inject the authenticated principal (set by JwtAuthGuard) into a handler.

Returns an AuthPrincipal — a discriminated union of user + service. Use .kind to branch:

@Get(‘me’) me(@CurrentUser() p: AuthPrincipal) { if (p.kind === ‘user’) return { email: p.email }; return { clientId: p.clientId }; }

Grab a single field by passing a key. The key is not type-narrowed against the principal kind — cast at the call site if you need type safety:

@Get() list(@CurrentUser(‘id’) userId: string) { … } // only valid for user principals

Parameters

…(string | PipeTransform<any, any> | Type<PipeTransform<any, any>> | undefined)[]
