PostHook

@tsed/mongoose

Usage

import { PostHook } from "@tsed/mongoose";

See /packages/orm/mongoose/src/types/decorators/postHook.ts.

Overview

function PostHook<T = any>(method: string, fn: MongoosePostHookCB<T>): ClassDecorator;
export function PostHook<T = any>(method: string, fn: MongoosePostHookCB<T>, options: MongooseHookOptions): ClassDecorator;
export function PostHook<T = any>(method: string, options: MongooseHookOptions): StaticMethodDecorator;

Description

We can simply attach a @PostHook decorator to your model class and define the hook function like you normally would in Mongoose.

import {Ignore, Required} from "@tsed/platform-http";
import {PostHook, Model} from "@tsed/mongoose";

@Model()
@PostHook("save", (car: CarModel) => {
   if (car.topSpeedInKmH > 300) {
       console.log(car.model, 'is fast!');
   }
})
export class CarModel {
   @Ignore()
   _id: string;

   @Required()
   model: string;

   @Required()
   isFast: boolean;

   // or Prehook on static method
   @PostHook("save")
   static postSave(car: CarModel) {
      if (car.topSpeedInKmH > 300) {
          console.log(car.model, 'is fast!');
      }
   }
}

This will execute the post-save hook each time a CarModel document is saved.
