REAL Code Examples from the Repository

Code Generation Example

Workflows can be converted to executable TypeScript code with the "use workflow" directive:

export async function welcome(email: string, name: string, plan: string) {
  "use workflow";

  const { subject, body } = await generateEmail({
    name,
    plan,
  });

  const { status } = await sendEmail({
    to: email,
    subject,
    body,
  });

  return { status, subject, body };
}

Generate Code for a Workflow

# Via API
GET /api/workflows/{id}/generate-code

The generated code includes type-safe TypeScript, real integration calls, error handling, and execution logging.

Workflow Management Example

List all workflows:

GET /api/workflows

Create a new workflow:

POST /api/workflows

Workflow Execution Example

Execute a workflow:

POST /api/workflows/{id}/execute

Get execution history:

GET /api/workflows/{id}/executions

AI Workflow Generation Example

Generate workflow from a prompt:

POST /api/ai/generate-workflow

Resend Email Integration Example

Send transactional emails with Resend's API:

import { sendEmail } from "@/lib/integrations/resend";

await sendEmail({
  to: "user@example.com",
  subject: "Welcome!",
  body: "Welcome to our platform",
});

Linear Ticket Integration Example

Create and manage Linear issues:

import { createTicket } from "@/lib/integrations/linear";

await createTicket({
  title: "Bug Report",
  description: "Something is broken",
  priority: 1,
});

PostgreSQL Database Access Example

Direct database access for queries and updates:

import { queryData } from "@/lib/integrations/database";

await queryData("users", { email: "user@example.com" });

External API Integration Example

Make HTTP requests to any API:

import { callApi } from "@/lib/integrations/api";

await callApi({
  url: "https://api.example.com/endpoint",
  method: "POST",
  body: { data: "value" },
});

Firecrawl Web Scraping Example

Scrape websites and search the web with Firecrawl:

import {
  firecrawlScrapeStep,
  firecrawlSearchStep,
} from "@/lib/steps/firecrawl";

// Scrape a URL
const scrapeResult = await firecrawlScrapeStep({
  url: "https://example.com",
  formats: ["markdown"],
});

// Search the web
const searchResult = await firecrawlSearchStep({
  query: "AI workflow builders",
  limit: 5,
});

Advanced Usage & Best Practices

Optimize Code Generation: Ensure your workflows are well-structured to generate clean and efficient TypeScript code.
Monitor Execution Logs: Regularly check execution logs to identify and resolve any issues quickly.
Secure Authentication: Use secure authentication methods like Better Auth to protect your workflows.
