See the README on cron jobs or the Pipedream docs to learn more about the platform at large. See our guide on making HTTP requests in Node for more examples. This will make a GET request to SWAPI, once a day at midnight, but you can modify this script to send any HTTP request, at any schedule. Then run pd deploy -run cronjob.js -timer -cron “0 0 * * *” In this example, we’ll hit the Star Wars API once a day.įirst, open your editor and create a file called http.js with the following contents: const axios = require("axios")

If you already host code at some URL, and just want to trigger a job to run via HTTP request, you can use Pipedream to send that request on a schedule. A practical example: send an HTTP request on a schedule

You can list all running jobs with pd list, update their code or schedule with pd update, and more. You can delete this job and all its logs by running: pd delete cronjob-js You can press Ctrl-C to quit the real-time stream, and listen for new logs later by running: pd logs cronjob-js The pd CLI will deploy your code to Pipedream, and print logs as the script produces them. This step will prompt you to sign up for Pipedream if you haven’t already. Then deploy that script to Pipedream, running it every 15 seconds: pd deploy -run cronjob.js -timer -frequency 15s cron expressions also supported with -cron

Watch this video or follow the step-by-step instructions below:įirst, install the Pipedream CLI: curl | shĬd into a directory with a Node script you’d like to run, or just create a simple one-line script: echo 'console.log("Hello, world")' > cronjob.js You can sign up and run any Node code on a schedule in less than one minute. You can also use pre-built actions to connect to hundreds of APIs and apps - actions are just Node functions that perform common operations against these APIs. You run serverless workflows - any Node.js code - triggered by HTTP requests, timers, emails, and more. Pipedream is an integration platform for developers. Airflow is great when you have complex dependencies between jobs, for example in data pipelines.īut when you just want to run a script on a schedule, they’re overkill. Kubernetes CronJobs or ECS Tasks are ideal when your code runs in a container. These options work well in their intended context: Lambda is great when you’re glueing together AWS resources. So it’s no surprise that we have other choices for scheduling code in 2020: This is an inaccessible option for many modern devs who operate far up the stack. Cron jobs are simple only if you cut your teeth on Linux and can effectively administer a server. In the era of the cloud, it’s also outdated. If you don’t already have a server where you can run jobs, setting one up just for cron is far from ideal. I used cron for email reminders, automated reports, backups: anything I could schedule, I did.Ĭron is simple: you just tell it what you want to run, when you want to run it: 0 0 * * * node script.js Run script.js once a dayīut it comes with tradeoffs: primarily, you have to operate a server to run it, which costs money and time.
I’ve been obsessed with automation my whole life, and as a fledgling developer cron became my workhorse.Īt the time, I worked at an IT help desk. I remember the first time I discovered cron.
