Introduction

Welcome to the Trigger.dev docs

Trigger.dev is an open source background jobs framework that lets you write reliable workflows in plain async code. Run long-running AI tasks, handle complex background jobs, and build AI agents with built-in queuing, automatic retries, and real-time monitoring. No timeouts, elastic scaling, and zero infrastructure management required.

Trigger.dev

How to get started in 3 minutes using the CLI and SDK.

Quick start

Go from zero to a working task in your Next.js app in 10 minutes.

Video walkthrough

Understand how Trigger.dev works and how it can help you.

How it works

There are some hard and soft limits that you might hit.

Limits

Tasks need to be triggered in order to run.

Triggering

Understanding the lifecycle of task run execution in Trigger.dev

Runs

How to authenticate with Trigger.dev so you can trigger tasks.

API keys

The `trigger.dev dev` command is used to run your tasks locally.

CLI dev command

You can use the dashboard to run a test of your tasks.

Run tests

The `trigger.dev deploy` command can be used to deploy your tasks to our infrastructure.

CLI deploy command

Any environment variables used in your tasks need to be added so the deployed code will run successfully.

Environment Variables

You can easily deploy your tasks with GitHub actions.

GitHub Actions

Tasks are the core of Trigger.dev. They are long-running processes that are triggered by events.

Overview

Writing tasks: Overview

How to use the built-in logging and tracing system.

Logging and tracing

How to deal with errors and write reliable tasks.

Errors & Retrying

Configure what you want to happen when there is more than one run at a time.

Concurrency & Queues

We use atomic versioning to ensure that started tasks are not affected by changes to the task code.

Versioning

Configure the number of vCPUs and GBs of RAM you want the task to use.

Machines

An API call or operation is “idempotent” if it has the same result when called more than once.

Idempotency

A replay is a copy of a run with the same payload but against the latest version in that environment. This is useful if something went wrong and you want to try again with the latest version of your code.

Replaying

Set a maximum duration for a task to run.

Max duration

Tags allow you to easily filter runs in the dashboard and when using the SDK.

Metadata

Run metadata

Get compute duration and cost from inside a run, or for a specific block of code.

Usage

Context

Perform actions like replay and cancel on multiple runs at once.

Bulk actions

Advanced usage

Trigger

Batch trigger tasks with up to 500 payloads.

Batch trigger

List runs in a specific environment. You can filter the runs by status, created at, task identifier, version, and more.

List runs

Retrieve information about a run, including its status, payload, output, and attempts. If you authenticate with a Public API key, we will omit the payload and output fields for security reasons.


Retrieve run

Creates a new run with the same payload and options as the original run.

Replay run

Cancels an in-progress run. If the run is already completed, this will have no effect.

Cancel run

Updates a delayed run with a new delay. Only valid when the run is in the DELAYED state.

Reschedule run

Update metadata

List all schedules. You can also paginate the results.

List Schedules

Create a new `IMPERATIVE` schedule based on the specified options.

Create Schedule

Retrieve Schedule

Update a schedule by its ID. This will only work on `IMPERATIVE` schedules that were created in the dashboard or using the imperative SDK functions like `schedules.create()`.

Update Schedule

Delete a schedule by its ID. This will only work on `IMPERATIVE` schedules that were created in the dashboard or using the imperative SDK functions like `schedules.create()`.

Delete Schedule

Deactivate a schedule by its ID. This will only work on `IMPERATIVE` schedules that were created in the dashboard or using the imperative SDK functions like `schedules.create()`.

Deactivate Schedule

Activate a schedule by its ID. This will only work on `IMPERATIVE` schedules that were created in the dashboard or using the imperative SDK functions like `schedules.create()`.

Activate Schedule

Get all supported timezones that schedule tasks support.

Get timezones

List all environment variables for a specific project and environment.

List Env Vars

Upload mulitple environment variables for a specific project and environment.

Import Env Vars

Create a new environment variable for a specific project and environment.
