Build, migrate, and deploy web-framework applications on Cloudflare Workers. Use when a framework project such as Astro, SvelteKit, React Router, TanStack Start, Nuxt, Hono, or a React or Vue SPA targets Cloudflare, or when a framework repository contains Workers deployment configuration.

The file

We split this skill into the rules it gives an agent

3 rules. About 0 are common, 2 are distinctive, and 1 is very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈2

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Read only the matching row below, its Workers framework guide, and the framework's own agent guidance.

    line 14
  2. Very specific:

    Existing project with Wrangler configuration: keep Wrangler and load the wrangler skill.

    line 17
  3. Distinctive:

    If the user reports that this skill gave incorrect or outdated guidance, or is missing information, read references/skill-feedback.md.

    line 36

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Build with frameworks on Cloudflare

Use the framework as the primary development interface and Cloudflare Workers as the deployment target. Serve static sites and SPA output with Workers Static Assets. Do not select Pages templates, Pages deployment commands, or Pages-specific presets for new applications. Preserve existing Pages deployments during unrelated maintenance.

Route the project

  1. Inspect the repository before changing it. Identify the framework, installed version, package manager, rendering mode, existing adapter, and Cloudflare configuration: cloudflare.config.ts, or wrangler.jsonc, wrangler.json, or wrangler.toml.
  2. Preserve the user's framework choice. Determine whether the task starts a new project, adapts an existing project, or changes only application code.
  3. Read only the matching row below, its Workers framework guide, and the framework's own agent guidance.
  4. Set up the project for its state:
    • New project: follow the framework's Workers guide for project creation. The guides currently create the project with C3 and configure it for Wrangler; this is an exception to the cloudflare skill's default of cf for new projects, because the cf docs do not yet cover creating framework projects. After creation, the project has Wrangler configuration, so the next bullet applies.
    • Existing project with Wrangler configuration: keep Wrangler and load the wrangler skill. Follow the framework guide for adapter and configuration changes. Do not run cf init ., cf dev, cf build, or cf deploy in it.
    • Existing project with no Cloudflare configuration: use cf, which detects supported frameworks and configures them; see Start from an existing project and the cf-cli skill. Detection does not mean the project builds. If the build fails or the framework is not supported, follow the framework guide's manual setup.
  5. Change only the adapter, runtime, build, and deployment configuration the integration requires. Inspect generated package scripts, run the framework's checks and build, then verify the Worker locally before deployment.
FrameworkWorkers setupOfficial upstream agent guidance
Next.jsLoad the nextjs-on-cloudflare skill.Listed in that skill.
TanStack StartFollow the Workers guide, which uses the Cloudflare Vite plugin. Distinguish Start from standalone TanStack Router.Use TanStack Intent to discover and load installed package skills, including Start's deployment guidance.
React RouterIdentify Framework, Data, or Declarative mode. Follow the Workers guide for full-stack setup. SPA mode is not supported with the Cloudflare Vite plugin, and prerendering has version requirements; check the guide before choosing either.Load the official React Router skill, its matching mode reference, and installed package docs when available.
SvelteKitFollow the Workers guide, which uses @sveltejs/adapter-cloudflare.Use Svelte's official skills and AI setup guidance.
HonoChoose an API-only Worker or a frontend plus API. The Cloudflare guide covers Hono with a React SPA; use Hono's Workers guide for an API-only app.Load the application skill from honojs/skills.
AstroDistinguish fully prerendered output from on-demand rendering: a static site deploys as static assets, and on-demand rendering uses @astrojs/cloudflare. Follow the Workers guide.Use Astro's official AI guidance and docs MCP.
NuxtFollow the Workers guide for the current Nitro integration and bindings.Use the Nuxt docs MCP; load the Nuxt UI skill only when using Nuxt UI.
React or Vue SPAFollow the React + Vite or Vue Workers guide. Distinguish a client-only SPA from a full-stack framework.Use the chosen framework's official guidance for application development.

For other frameworks, start from the framework guides index.
