Is there any useContainer(Container); method like routing-controller?

[sirfak]

Hi
I was suggested to use koa-ts-controller as i was using routing controller before.

How do we inject Container from typedi like routing-controller package
useContainer(Container);

Thanks
Ajay

Cast @iyobo , I think it good idea to support basic DI, same as type-graphql does. I suggest it as option for bootstrapMiddleware instead of function call

This will be added soon.
For now to get an index of controller instances:

import {getControllers} from 'koa-ts-controllers`
const indexOfControllerInstances = getControllers();

Hi @iyobo, thank you for reply. Honestly I decided to use koa with router directly and avoid any abstractions, but hope this can be useful for other people. So for case of koa, dependency injection is just like this: app.context = myDb and then use in controllers as ctx.db.findOne().

Functional programming rules, and I highly inspired by way choosen by Vue 3, they decided to use functional style api versus classes with decorators.

We should follow the nature, since it doesn’t have unnecessary abstraction and learn from it.

Cheers.

@georgyfarniev
That example is within the jurisdiction of the developer to inject.
You could do:

koa.use(ctx => {
  ctx.db = yourDB;
});

The dependency injection concerns of koa-ts-controllers as of right now revolve around ways to get things out of ctx e.g

@Put('/:userId/profile')
  async deleteUserSubreddit(@Params() userId: number, @Ctx('db') db: YourDB) {
       const one  = await db.findOne()
  }

I am still considering the useContainer paradigm. More to come soon!
