InversifyJS: Cannot find name 'Controller' (express-utils)

Expected Behavior

The Controller should be found.

Current Behavior

An error is thrown (in stack trace at the bottom). Short Version Cannot find name Controller

Possible Solution

Currently I don´t have one.

Steps to Reproduce (for bugs)

Create a file with the following Testcode:

import { injectable, interfaces, Kernel } from 'inversify';
import { Controller, InversifyExpressServer, TYPE } from 'inversify-express-utils';

const kernel: interfaces.Kernel = new Kernel();
kernel.bind<Controller>(TYPE.Controller).to(MyController).whenTargetNamed('MyController');


@injectable()
@Controller('/api')
class MyController {
  constructor() {
    console.log('do something');
  }
}

Try running it with ts-node

Context

The error is thrown in line 5. But in line 2 the Controller is imported so the error should not be thrown. The code is started with ts-node test.ts, but trying to compile it with tsc test.ts the same error is thrown.

Thanks! 😄 I will document here the fix…

To fix this problem you need to use inversify-express-utils@2.0.2 then you can import both interfaces and Controller decorator:

import { injectable, interfaces as inversifyInterfaces, Kernel } from 'inversify';
import { interfaces as expressUtilsInterfaces, Controller, InversifyExpressServer, TYPE } from 'inversify-express-utils';

const kernel: inversifyInterfaces.Kernel = new Kernel();
kernel.bind<expressUtilsInterfaces.Controller>(TYPE.Controller).to(MyController).whenTargetNamed('MyController');


@injectable()
@Controller('/api')
class MyController implements expressUtilsInterfaces.Controller {
  constructor() {
    console.log('do something');
  }
}

@remojansen thanks! Working now. Ideally, would be nice to be able to import Controller as is, but that’s just me being too picky 😄 Thank you!
