Add Async Hook context support in Ts.ED.

Usage

Ts.ED provide an injectable [RequestContext] to get all request and response information during a request. But, you have to inject the context from your controller and forward context instance manually to the service.

@Injectable()
export class CustomRepository {
  async findById(id: string, ctx: PlatformContext) {
    ctx.logger.info("Where are in the repository");
    return {
      id,
      headers: this.$ctx?.request.headers
    };
  }
}

@Controller("/async-hooks")
export class AsyncHookCtrl {
  @Inject()
  repository: CustomRepository;

  @Get("/:id")
  async get(@PathParams("id") id: string, @Context() ctx: PlatformContext) {
    return this.repository.findById(id, ctx);
  }
}

With this package, you can inject directly the PlatformContext in the service without injecting it in the controller:

@Injectable()
export class CustomRepository {
  @InjectContext()
  $ctx?: PlatformContext;

  async findById(id: string) {
    this.ctx?.logger.info("Where are in the repository");

    return {
      id,
      headers: this.$ctx?.request.headers
    };
  }
}

@Controller("/async-hooks")
export class AsyncHookCtrl {
  @Inject()
  repository: CustomRepository;

  @Get("/:id")
  async get(@PathParams("id") id: string) {
    return this.repository.findById(id);
  }
}

Installation

Async Hook context required Node.js at least v13.10.0. `

Install the @tsed/async-hook-context:

npm install --save @tsed/async-hook-context

Then import @tsed/async-hook-context in your Server:

import {Configuration} from "@tsed/common";
import "@tsed/async-hook-context";

@Configuration({})
export class Server {}
