Getting Started with Trigger.dev

To get started with Trigger.dev, follow these steps to set up and run your first task. The process is straightforward and involves using the CLI for initial setup, followed by task execution and monitoring through the dashboard.

1. Install Trigger.dev Using the CLI

The easiest way to start using Trigger.dev is by utilizing the CLI. Run the following command in the root directory of your project:

npx trigger.dev@beta init

This command performs several actions:

• Login: It logs you into the CLI if you aren’t already.
• Configuration File: Creates a trigger.config.ts file in your project’s root directory.
• Directory Creation: Prompts you to specify where to create the /trigger directory and sets it up with an example task (/trigger/example.[ts/js]).

You will also be asked to install the “Hello World” example task, which will be used to test your setup.

2. Run Your Tasks Locally

Once the initial setup is complete, use the CLI dev command to start a server that runs and manages your tasks:

npx trigger.dev@beta dev

This command will:

• Watch for Changes: Continuously monitor the /trigger directory for changes.
• Register Tasks: Communicate with the Trigger.dev platform to register and manage tasks.
• Update Packages: Check for updates to @trigger.dev/* packages to prevent version mismatches.

3. Perform a Test Run

The CLI dev command will output several useful URLs. To test your setup:

1. Visit the Test Page: Open the URL provided by the CLI to access the Test page.
2. Select Example Task: You should see the Example task listed. Select it and, if necessary, enter any required payload data (for the Hello World task, no input is needed).
3. Run Test: Click the “Run test” button to execute the task.

4. Monitor Task Execution

After initiating the test run, you can monitor the task execution:

• Run Page: The Run page will show live updates on the task’s status.
• Terminal Output: The terminal will display the task status and provide links to the run log.
