Getting 404 from inversify-express-utils controller

Question

I'm struggling to get an inversify-express-utils service properly configured. I'm trying to use two controllers, but only one of them seems to be discovered by inversify.

With my current configuration, only helloController seems to be registering. Requests to GET .../api/v1/hello respond as expected with 200 OK. However, requests to GET .../api/health respond with 404 NOT FOUND.

What am I doing wrong?

Here is my current configuration:

src
│
└──api
   │  index.ts
   │
   └──controller
      │  index.ts
      │  healthController.ts
      │
      └──v1
         │  index.ts
         │  helloController.ts

src/api/index.ts

import "reflect-metadata"
import {Container} from "inversify"
import {InversifyExpressServer} from "inversify-express-utils"
import "./api/controller"

const inversifyContainer = new Container()
const server = new InversifyExpressServer(inversifyContainer)
const serverInstance = server.build()
serverInstance.listen(3000)

src/api/controller/index.ts

export * from "./healthController"
export * from "./v1/"

src/api/controller/healthController.ts

import {Request, Response} from "express"
import {BaseHttpController, controller, httpGet} from "inversify-express-utils"

@controller('/')
export class HealthController extends BaseHttpController {

    constructor(){ super() }

    @httpGet('/health')
    private health(req: Request, resp: Response) {
        resp.json({uptime: process.uptime()})
    }
}

src/api/controller/v1/index.ts

export * from "./helloController"

src/api/controller/v1/helloController.ts

import {Request, Response} from "express"
import {BaseHttpController, controller, httpGet} from "inversify-express-utils"


@controller('/v1/hello')
export class helloController extends BaseHttpController {

    @httpGet('/')
    private hello(req: Request, resp: Response) {
        resp.send("Hello, World!")
    }
}

Answer 1

Figured it out.

The @controller() annotation doesn't seem to work with a root ('/') path.

Works after changing healthController.ts to the following

import {Request, Response} from "express"
import {BaseHttpController, controller, httpGet} from "inversify-express-utils"

@controller('/health')
export class HealthController extends BaseHttpController {

    @httpGet('/')
    private health(req: Request, resp: Response) {
        resp.json({uptime: process.uptime()})
    }
}

Answer 2

Ensure you have added the done controller binding in your inversify container. So it would look like the following:

 const container = new container();

`container.bind<Controller>(TYPES.Controller).to(Controller)`

This will ensure that you don't get 404 not found and your controller is correctly registered(bound) in your inversify container

It works well, but you shouldn't use a slash as a root path:

import {Request, Response} from "express"
import {BaseHttpController, controller, httpGet} from "inversify-express-utils"

@controller('')
export class HealthController extends BaseHttpController {

    @httpGet('/health')
    private health(req: Request, resp: Response) {
        resp.json({uptime: process.uptime()})
    }
}
