What is Trigger.dev?

Limits

Projects are a group of [Jobs](/documentation/concepts/jobs) with [Environments](/documentation/concepts/environments-endpoints)

Projects

The Client is how you interact with the API, through an Adaptor.

Client & Adaptors

HTTP endpoints allow you to trigger your Jobs from any webhooks.

HTTP endpoints

Runs are resumable by returning Task stored data

Resumability

Delays can be used to wait for a certain amount of time before continuing a Run.

Integrations make it easy to use APIs in your Jobs

Integrations

Authenticate your users with an Integration using Trigger.dev Connect.

Trigger.dev Connect

Environments and Endpoints are used to connect your server to the Trigger.dev platform.

They are declarative pattern-matching rules, modeled after [AWS EventBridge patterns](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-event-patterns.html).

SDK: Introduction

Job is used to create and configure a Job

The third parameter in a Job's `run()` function. An object that contains information about the Organization, Job, Run and more.

Context

The payload of a Run's completion webhook

RunNotification

Use `invokeTrigger()` to allow a Job to be manually triggered using `Job.invoke()`

invokeTrigger()

`eventTrigger()` is set as a [Job's trigger](/sdk/job) to subscribe to an event a Job from [a sent event](/sdk/triggerclient/instancemethods/sendevent).

eventTrigger()

`cronTrigger()` is set as a [Job's trigger](/docs/sdk/job) to trigger a Job on a recurring schedule using a CRON expression.

cronTrigger()

`intervalTrigger()` is set as a [Job's trigger](/sdk/job) to trigger a Job at a recurring interval.

intervalTrigger()

`HttpEndpoint` allows you to create and HttpTrigger, which means you can trigger your Jobs from any webhooks

HttpEndpoint

`HttpTrigger` allows you to trigger your Jobs from any webhooks.

HttpTrigger

An object containing the auth data for an integration that's using hosted auth.

ConnectionAuth

Use this function if you're using a `try/catch` block to catch errors.

An easy way to redact sensitive information from a string

Verify webhook payloads when they're using common signing methods.

Send an event to Trigger.dev to trigger job runs through eventTrigger()

The React SDK allows you to display the status of your Jobs and Runs in your React app.

React SDK: Introduction

The `TriggerProvider` component allows any hooks lower in the React hierarchy to connect to the Trigger.dev API.

TriggerProvider

The `useEventDetails()` React hook will show the live status of an event that was sent using `sendEvent()`.

useEventDetails()

The `useEventRunDetails()` React hook will show the live status of the first run triggered by `sendEvent()`.

useEventRunDetails()

The `useRunDetails()` React hook will show the live status of run.

What features are currently available in the Developer Preview

Feature matrix

Your tasks live inside /trigger folders. Code in these is bundled and deployed together.

/trigger folders

Tasks are functions that can run for a long time and provide strong resilience to failure.

Tasks

Tasks: Overview

Triggering

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

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

Environment Variables

The `trigger.dev deploy` command can be used to manually deploy.

CLI deploy command

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.

Writing tasks: Introduction

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

You can reattempt a task that has failed all of its attempts. You can also replay a task with a new version of your code.

Reattempting & Replaying

You can add filters to your tasks so they're only triggered when certain conditions are met.

Trigger filters

Send and receive notifications from your tasks to make your other systems aware of changes. For example, you can live-update your website as a task progresses.

Notifications

You can rollback changes when errors happen, to give transactional guarantees to your operations.

Rollbacks

You can use any Node.js library inside the run function, or do HTTP requests.

Using APIs

This function is called before the `run` function, it allows you to wrap the run function with custom code.

Middleware

Automated tests

The dashboard has many features including: managing your projects, viewing run logs, editing environment variables and more.

Tasks are individual building blocks of a Run.
