Core Concepts: Understanding Triggers, Jobs, and Integrations

Trigger.dev simplifies workflow automation, and at its core are three fundamental concepts: Triggers, Jobs, and Integrations. Let's break them down:

Triggers: The Starting Gun

Triggers are the events that kick off your automated workflows. Think of them as the "if" in an "if this, then that" statement.

• Webhook Events: These are signals sent from external services when something happens. For example, a webhook from Stripe when a payment is received.
• Scheduled Events: Automate tasks on a recurring basis, like sending daily reports or cleaning up database entries. You can learn more about event sources in the Learn section.

Jobs: The Automated Actions

Jobs define what happens after a trigger fires. They are the "that" in our "if this, then that" equation:

• Task Execution: Jobs can execute code to perform actions like sending emails (think welcome emails using marketing automation), processing data, or updating databases.
• Serverless Functions: Because Trigger.dev is serverless, Jobs execute without you needing to manage servers. This can be a huge advantage if you are using it for Software Developer Tools.

Integrations: The Connectors

Integrations are pre-built connectors that streamline communication with popular services.

• API Integrations: They simplify tasks like sending messages to Slack, processing payments with Stripe, or interacting with GitHub repositories. These API Integrations save developers time and effort.
• Simplified Management: Version 4 simplifies how you define and manage triggers, jobs, and integrations.

> By orchestrating Triggers, Jobs and Integrations with simple elegance, Trigger.dev v4 empowers developers to build sophisticated serverless workflows with ease.

client.define({
  id: "new-user",
  name: "New User Signup",
  trigger: eventTrigger({
    name: "user.signup",
  }),
  run: async (payload, io, ctx) => {
    // Workflow logic will go here
  },
});

Creating the Job and Configuring Integrations

Now let's create a job within the workflow to send the email. This often involves integrating with an email service provider like SendGrid or Mailgun. Trigger.dev provides pre-built integrations to make this easier.

javascript
    await io.sendEmail("send-welcome-email", {
      to: payload.email,
      from: "welcome@example.com",
      subject: "Welcome to Our Platform!",
      html: "
Welcome aboard!
",
    });
