Send Guard Decorator

Send Guard Decorator#

This decorator defines whether the event should be sent or not depending on the returned result. Requires PusherEvent to be defined in your route otherwise is not executed.

Example#

import { Controller, Get } from '@nestjs/common';
import { PusherChannel, PusherSendGuard } from 'nestjs-pusher';

const shouldSend = (req: any, res: any, eventName: string) => {
  //Do whatever logic you need
  return true
}

@Controller('cats')
export class CatsController {
  constructor(private readonly catService: CatService) {
    //Imaginary service for the sake of the example
  }

  @PusherSendGuard(shouldSend)
  @PusherChannel('private-channel-of-cats')
  @PusherEvent('cat.created')
  @Post()
  async createCat(@Body() dto): string {
    const newCat = await this.catService.create(dto)
    //The return value will be used as the content
    return newCat
  }
}
