Cron / Background jobs / Tasks

In SolidJS which also uses Nitropack under the hood it was possible to setup cron jobs using Nitropack. See docs here: https://nitro.build/guide/tasks And specific implementation in SolidJS: https://github.com/solidjs/solid-docs/issues/964 AFAIK SolidJS did nothing to enable this and it just came out of the box by using Vinxi and Nitropack. I just tried the same with Tanstack Start and while I can add those configurations in app.config.ts the tasks seem to be ignored. Do you guys know by any chance how to enable that feature somehow? Thanks 🙏 Disclamer - I know this out of scope for this so no worries if nobody wants to spend time on it; in fact thanks for this amazing library already 🙏 - I know ideally one should run tasks in a separate process/thread since node is single threaded; my specific use case is for an app that works in a specific timezone and has traffic downtime during the night and I can run some simple and fast cleanup tasks.

how does your app.config.ts look like? it might be we just don't pass on those things to vinxi

generous-apricotOP•9mo ago

import { defineConfig } from "@tanstack/start/config";
import tsConfigPaths from "vite-tsconfig-paths";

export default defineConfig({
  vite: {
    plugins: [
      tsConfigPaths({
        projects: ["./tsconfig.json"],
      }),
    ],
  },
  server: {
    experimental: {
      tasks: true,
    },
    scheduledTasks: {
      "* * * * *": ["cron"],
    },
  },
});

import { defineConfig } from "@tanstack/start/config";
import tsConfigPaths from "vite-tsconfig-paths";

export default defineConfig({
  vite: {
    plugins: [
      tsConfigPaths({
        projects: ["./tsconfig.json"],
      }),
    ],
  },
  server: {
    experimental: {
      tasks: true,
    },
    scheduledTasks: {
      "* * * * *": ["cron"],
    },
  },
});

Here you go

exotic-emerald•9mo ago

i checked, we forward this to vinxi (everything in server) so this should work in terms of vinxi configuration at least which vinxi version are you using?

generous-apricotOP•9mo ago

0.5.1

exotic-emerald•9mo ago

try downgrading to 0.4.3 maybe it broke in vinxi? and nitro

generous-apricotOP•9mo ago

tried downgrading and it's still not working Something that I remember used to happen in SolidJS was that there was a message saying "registered task XYZ" or something along those lines. That's also nowhere to be found. Hold on I can just push this into a repository so that you have a reproducible env

exotic-emerald•9mo ago

so maybe the cron.ts file is not where it should be?

generous-apricotOP•9mo ago

If that was the cause it would say something like "task not registered because it was not found" Hold let me give you the exact messages Nevermind. I can't make them work in SolidJS so yeah something broke with nitro probably. Thanks anyway 🙏

i guess we'll just have to wait then

generous-apricotOP•9mo ago

Nope. I've posted here: https://github.com/nitrojs/nitro/issues/1974#issuecomment-2542516974 but apparently it's not something that was ever available I guess I've hallucinated it

fair-rose•9mo ago

generous-apricotOP•9mo ago

Boring hallucination if you ask me

fair-rose•9mo ago

how do you go about scheduling tasks then ? any recommendation ?

generous-apricotOP•9mo ago

Luckily for me I can delay the implementation for a few months but if I had to implement it today I'd probably have a separate worker / server running the background task. I'd put the code for it inside the current codebase (or maybe create a monorepo with multiple packages) and just run tsx cron-script.ts in some worker. If you want to keep everything in the same app/deployment then I'd probably use concurrently to run both the server and the cron tasks script (probably using node-cron or similar) but it's not clear how production ready concurrently is If concurrently is not good for prod I'd go with Docker + linux crontab If you are doing serverless I have no idea as I tend to avoid that world

fair-rose•9mo ago

Thanks for the insight. I'm running both services (along with the db) in a docker compose for now the issue with something like concurrently (unless im wrong) is that there is no proper way to restart the job scheduler if it crashes, is there ?

generous-apricotOP•9mo ago

That's right. If you are already using docker-compose maybe a separate container is the best option for you. You should be able to handle restarts as well.

You can also try PM2 to run a cron on the same or another process.
