Templates for Cloudflare Workers

workers.cloudflare.com

Cloudflare Workers let you deploy serverless code instantly across the globe for exceptional performance, reliability, and scale. This repository contains a collection of starter templates for building full-stack applications on Workers. You are encouraged to use, modify, and extend this code!

Getting Started

There are two ways to start building with a template in this repository: the Cloudflare dashboard and C3 (the create-cloudflare CLI).

Starting from the Dashboard

After logging in or signing up through the Cloudflare dashboard, open the Workers templates page and select a template to get started with. From here, you can create a repository and deploy your first Worker without needing a local development environment.

Starting via CLI

To get started locally, run one of the following commands:

npm create cloudflare@latest
# or
pnpm create cloudflare@latest
# or
yarn create cloudflare@latest

For more information on getting started with our CLI, check out the getting started guide.

End-to-End Testing

This repository includes a comprehensive Playwright-based E2E test suite that validates all templates to ensure they work correctly. The test system supports both local development mode (spinning up dev servers) and live mode (testing against deployed templates).

Running E2E Tests

Local Development Mode (Default)

By default, tests run against locally started development servers:

# Run all E2E tests
pnpm run test:e2e

# Run tests for specific templates
pnpm run test:e2e astro-blog-starter-template.spec.ts
pnpm run test:e2e saas-admin-template.spec.ts

# Run tests with UI mode for debugging
pnpm run test:e2e --ui

In local mode:

• Tests start development servers automatically for each template
• Uses one worker to prevent port conflicts
• Servers are properly cleaned up between different template tests
• Longer timeouts to account for build and startup time

Live Mode (Testing Deployed Templates)

To test against live deployed templates, set the PLAYWRIGHT_USE_LIVE environment variable:

# Run tests against live deployed templates
pnpm run test:e2e:live

# Run specific template tests in live mode
pnpm run test:e2e:live saas-admin-template.spec.ts

In live mode:

• Tests run against https://{template-name}.templates.workers.dev
• Enables parallel execution (up to 4 workers locally, 2 in CI)
• Faster execution since no local server startup required
• Shorter timeouts since templates are already running

Test Architecture

The test system includes:

• Automatic template discovery: Finds all *-template directories and analyzes their framework
• Smart server management: Detects framework type (Astro, Next.js, Vite, etc.) and uses appropriate ports
• Reliable cleanup: Properly terminates process trees between test runs
• Flexible URL resolution: Automatically determines live URLs from wrangler.json configuration

 

Playwright Codegen

Playwright includes a test code generation utility that records your actions in a chromium browswer. To start the codegen utility run

pnpm playwright codgen
