Cron jobs

[iammrsea]

Hello guys, I would appreciate if anyone could assist me with this problem. I have a cron job I would like to start after application boot, but I don't seem to have figured out the appropriate place to start it. I have tried the AppProvider lifecycle hooks, but it failed with 'E_IOC_LOOKUP_FAILED: Cannot resolve Adonis/Lucid/Orm namespace from the IoC Container'. Obviously, my cron job service provider depends on some of my Lucid models. Any ideas? Of course, I am using V5

Getting same error as in here: https://forum.adonisjs.com/t/adonis-5-command-database-ioc-error/6217
Maybe this solves it too :)

import { BaseCommand } from '@adonisjs/ace'
import { Kernel } from '@adonisjs/ace'
import { inject } from '@adonisjs/fold'
import { DatabaseContract } from '@ioc:Adonis/Lucid/Database'
import { ApplicationContract } from '@ioc:Adonis/Core/Application'

@inject([null, null, 'Adonis/Lucid/Database'])
export default class Hurr extends BaseCommand {
  public static commandName = 'hurr'
  public static description = 'Durr'

  constructor (app: ApplicationContract, kernel: Kernel, private db: DatabaseContract) {
    super(app, kernel)
  }

  public static settings = {
    loadApp: true,
  }

  public async handle () {
    console.log(this.db)

    this.logger.info('Hello world!')
  }
}

Been using CRON calling Ace commands as scheduler, but it would be cool indeed to have something like that built in (or as community package)

I saw that @reg2005 made a package to schedule tasks.

This was very helpful, thanks.

My use case:

A client wants to be able to send health tips notification to his customers once per day at a fixed time, say 6am.

My working implementation:

import NotificationService from "../services/NotificationService";
import { BaseCommand } from "@adonisjs/ace";
import { inject } from "@adonisjs/fold";
import { Kernel } from "@adonisjs/ace";
import { schedule } from "node-cron";
import { ApplicationContract } from "@ioc:Adonis/Core/Application";
import { DatabaseContract } from "@ioc:Adonis/Lucid/Database";
import FirebaseConfig from "../config/firebase";

@inject([null, null, "Adonis/Lucid/Database"])
export default class Notification extends BaseCommand {
  public static commandName = "notification";
  public static description = "Notification cron command";
  private readonly provider = new NotificationService(FirebaseConfig);

  constructor(
    app: ApplicationContract,
    kernel: Kernel,
    private db: DatabaseContract
  ) {
    super(app, kernel);
  }

  public static settings = {
    loadApp: true,
  };
  public async handle() {
   console.log('scheduling notifications...);
    await this.scheduleHealthTips("* 6 * * *");
  }
  private async scheduleHealthTips(cronExpression: string) {
    schedule(cronExpression, async () => {
      //my logic here
    });
  }
 
}

I run the serve and notification ace commands with npm-run-all package

Why not just use crontab and fire an ace command? I am not sure about schedulers written in js, crontab is much more low level and will fire anyway, even if server restarted or something happened with your app and no need to use any package, just run crontab -e and then you write something like this * 6 * * * /path/to/your/app/node ace notification

Laravel has same: https://laravel.com/docs/8.x/scheduling.
If I want to run some simple job, I prefer to use were built into the scheduling framework,

The advantage of doing this is that it is managed in one place, which is easy enough to migrate, and I only need one line of command on the server, so I don't feel overwhelmed after resetting the server system.
