CloudflareDeployer

The CloudflareDeployer deploys Mastra applications to Cloudflare Workers, handling configuration, environment variables, and route management. It extends the abstract Deployer class to provide Cloudflare-specific deployment functionality.

Usage Example

import { Mastra } from '@mastra/core';
import { CloudflareDeployer } from '@mastra/deployer-cloudflare';
 
const mastra = new Mastra({
  deployer: new CloudflareDeployer({
    scope: 'your-account-id',
    projectName: 'your-project-name',
    routes: [
      {
        pattern: 'example.com/*',
        zone_name: 'example.com',
        custom_domain: true,
      },
    ],
    workerNamespace: 'your-namespace',
    auth: {
      apiToken: 'your-api-token',
      apiEmail: 'your-email',
    },
  }),
  // ... other Mastra configuration options
});

  },
  "routes": [
    // Route configurations if specified

}

Route Configuration

Routes can be configured to direct traffic to your worker based on URL patterns and domains:

const routes = [
  {
    pattern: 'api.example.com/*',
    zone_name: 'example.com',
    custom_domain: true,
  },
  {
    pattern: 'example.com/api/*',
