Node.js setup guide

The easiest way to get started is to use the CLI. It will add Trigger.dev to your existing project, create a /trigger folder and give you an example task.

Run this command in the root of your project to get started:

It will do a few things:

1. Log you into the CLI if you’re not already logged in.
2. Create a trigger.config.ts file in the root of your project.
3. Ask where you’d like to create the /trigger directory.
4. Create the /trigger directory with an example task, /trigger/example.[ts/js].

Install the “Hello World” example task when prompted. We’ll use this task to test the setup.

The CLI dev command runs a server for your tasks. It watches for changes in your /trigger directory and communicates with the Trigger.dev platform to register your tasks, perform runs, and send data back and forth.

It can also update your @trigger.dev/* packages to prevent version mismatches and failed deploys. You will always be prompted first.

The CLI dev command spits out various useful URLs. Right now we want to visit the Test page

You should see our Example task in the list

Press the “Run test” button

Congratulations, you should see the run page which will live reload showing you the current state of the run.

If you go back to your terminal you’ll see that the dev command also shows the task status and links to the run log.
