Create webhook/callback when a job is completed

[sleek cove]

How do you send a request to the browser from the server using axios?

sorry i think I didn't explain very clearly.
The user is using an endpoint (POST), with a payload that contains the URI that he wants to specify for the webhook.
When the job is completed, i would like to notify him that the job is finished (with some additional information about the job).

[sleek cove]

Ah, so they should have their own server set up to receive these updates. Yeah okay, that makes sense

[rugged ruin]

yes ! I was thinking about using axios to send those job's information when the job is finished, would it be the best way to do it ?
i tried to find some "webhook/callback" implementation with nestjs

[sleek cove]

They give you an endpoint to call, so yeah, using an HTTP client to call that endpoint with the correct data is a pretty good way to go about it. Anything else would require re-architecting the endpoint on the clieint side, right? Like if you wanted to send a socket event via websockets/socket.io they'd have to set up a websocket server instead/parallel to their current server

Call injected gateway from DI into your job.
this.injectedGateway.server.emit('EventName, 'EventData')

hi, can you give more information about this ?

Read documentation about Nest.js Gateway : https://docs.nestjs.com/websockets/gateways

[raven moss]

Create gateway from CLI nest g ga MyGateway

[raven moss]

Inject gateway into your controller

class AppController {
 constructor(
  private readonly myGateway: MyGateway,
  private readonly scheduleRegistry: ScheduleRegistry
  ) {}
