Deploy background workers.

What you can keep running

Background workers fit code that waits continuously for more work and does not need an HTTP URL or schedule.

From code to an always on worker

Use a normal long running process. We keep it available while you keep ownership of how it receives and processes work.

Just write your worker

Loop, wait for work, and log what matters. We handle the process around it.

Node.js worker loop

const sleep = (ms) => new Promise((resolve) => setTimeout(resolve, ms));

async function run() {
  while (true) {
    console.log('checking queue');
    // Pull a job from SQS, Redis, RabbitMQ, etc.
    await sleep(30000);
  }
}

run().catch((err) => {
  console.error(err);
  process.exit(1);
});

Python poller

import time

def sync_once():
    print('syncing upstream data')
    # Call an API, write to your database, repeat.


while True:
    sync_once()
    time.sleep(30)

Go worker loop

package main

import (
    "log"
    "time"
)

func main() {
    for {
        log.Println("processing next event")
        // Read from Kafka, Kinesis, or a queue.
        time.Sleep(30 * time.Second)
    }
}
