question: Inject Private Property

[bestickley]

I was trying to... inject a private property:

The problem: I'm getting the TypeScript error: "Decorators are not valid here"

That is expected, private fields cannot be decorated by design. However, you can try to create a getter and decorate that. (I haven’t tried it myself, but the spec allows it)

@attilaorosz - this is not true. It used to work in earlier versions. Started to acting up around 0.8.0. Currently with 0.10.0 I find, that @Inject() works in one place in code and fails in others. Calling container directly via Container.get in the same place works with no issue.

This used to work but doesn't anymore with 0.10.0:

@Service()
@RestController('some-settings', 2)
export class SomeSettingsV2Resource {
    @Inject()
     private getAlHandler: GetAllHandler;

    @Inject()
    private getSomeSettingsHandler: GetSomeSettingsHandler;

}

this also doesn't work:

@Service()
@RestController('some-settings', 2)
export class SomeSettingsV2Resource {
    constructor(
        @Inject(() => GetAllHandler)
        private readonly getAllHandler: GetAllHandler,
        @Inject(() => GetSettingHandler)
        private readonly getSettingHandler: GetSettingHandler
    ) {} 
}

This works though:

@Service()
@RestController('some-settings', 2)
export class SomeSettingsV2Resource {
   
    constructor(
        private readonly getAllHandler: GetAllHandler = Container.get(GetAllHandler),
        private readonly getSettingHandler: GetSettingHandler = Container.get(GetSettingHandler)
    ) {}
       
}
