Current behavior

Resuming my case of use: I have a simple controller that GET /redirects, POST /redirects and POST /redirects/update. This last one fetch an external URL and add to my database a list of redirects. Then, with my simple structure, I added a new decorator that I created.

@Post('/update')
@Cron('*/5 * * * * *')
update() {}

This Cron function is added to a list and after my app.listen I init and invoke the method update (or whatever I add the decorator).

The problem is, to call this update, I can do: this.app.select(RedirectsModule).get(RedirectsController).update();, but I can’t run this by string name, only the component.

Expected behavior

What I need is that select and get accepts string, not the Module and Controller.

A workaround I found is to create an array like:

[
   { name: 'FooModule', module: FooModule },
   { name: 'BarModule', module: BarModule }
]

and search the .module based on .name. But I don’t think it’s the best to use.

Anyway, if anybody has a batter solution to add my “cron jobs”, I would appreciate.

Hi @eliasjnior Did you see https://github.com/OptimalBits/bull ? it’s The fastest, most reliable, Redis-based queue for Nodejs. as said

it also supports Scheduled and repeat jobs according to a cron specification. so I think it will be suited here. in fact, @fwoelffel created a Dynamic Module around it. nest-bull, so it can be used in nest-ish way, thanks Frédéric 😄 .

So back to the Monkey Patching 😂 that you did with nest container. imo, it’s very bad idea to get direct access to the container, as it was my idea at first 😄 see here #282

see also this pull #283 . and now we have Dynamic Module so we can write our 3rd party module, did you checked out NestRouterModule it’s a very good, simple example of how you could make your own dynamic modules that could be configured and change behavior as this this configuration .

Regards.
