I got a similar problem with the IoC. I'm declaring a contract and trying to import it into a command file. // contracts/cron.ts
declare module '@ioc:Adonis/Addons/Cron' {
abstract class CronJob {
// ...
}
}import { CronJob } from '@ioc:Adonis/Addons/Cron'But I'm having the same output message as @milgner : IocLookupException: E_IOC_LOOKUP_FAILED: Cannot resolve "Adonis/Addons/Cron" namespace from the IoC Container |

Could you both post more of your code? Remember that the items are not available from raw imports (since those imports happen when the file is read by node), but rather you have to use the appropriate To be more specific, make sure you're using the |

I think these might be two separate issues. Since I already successfully created one service and was under the impression that I understood how things worked, I now did a bit of divide-and-conquer on my setup it turns out that the error is different than I first thought. Effectively it boiled down to this: Everything works fine up to the point where, inside my service, I import and use (I guess if the import is not used in the file that it is optimized away before it can cause issues.) Here's the full output: Note that I can send mails with the |

Just had another go at this because I notized that the file containing my service definition was, alphabetically sorted, before the |

Hey all of you! 👋 Could you please post some code of what you are doing? Also, take notes that if you are doing a Service Provider, this behavior is intended, you shouldn't rely on framework internals when building a service provider. |

Didn't worked for me what am I missing? // contracts/interfaces/User.interface.ts
declare module '@ioc:Project/UserInterface' {
export default interface UserInterface {
...
}
}// providers/User/index.ts
import UserInterface from '@ioc:Project/UserInterface'
export default class UserService implements UserInterface {
...
}// providers/AppProvider.ts
import {ApplicationContract} from '@ioc:Adonis/Core/Application'
import UserService from './User';
export default class AppProvider {
constructor (protected app: ApplicationContract) {
}
public register () {
this.app.container.bind('./UserService', () => {
const Config = this.app.container.use('Adonis/Src/Config');
return new UserService(Config)
});
}
// no values for other functions
}Also tried your solution above still encountered the error. |

You should import your UserService like this import { ApplicationContract } from "@ioc:Adonis/Core/Application"
/**
* @class FooProvider
* @classdesc Provides the Foo service to the application.
*/
export default class FooProvider {
public static needsApplication = true // THIS CAUSED ME SO MUCH PAIN!!! 😫😫😫
constructor(protected app: ApplicationContract) {}
public register(): void {
const { default: FooService } = await import("../services/FooService")
this.app.container.singleton("MyApp/Foo", () => {
return new FooService()
})
}
}But this will not fix the problem if you import in your FooService another service that was made like this one (FooService). |

Hi This works for me, resolving the service in the provider.

So I started building a small application with Adonis.js and so far everything has been really nice!
There's one thing I can't seem to wrap my head around, though:
I have a service that provides a function to create a URL. I'm injecting it into a controller and a listener and everything works fine. Now however I started enhancing another service - which by itself can also be injected just fine - in a way that would also require it to use this URL-generation service.
As soon as I add the ioc-import (at the end of my imports), the application stops build and complains about
The Mail import is my second import, though, even before the newly-added import. Are there any recommendations / best practices for this kind of scenario? I think that using services from other services is not that uncommon?
