Cloudflare Pages

Full-stack application hosting with Git-based or Direct Upload deployments to Cloudflare's global network.

Quick Navigation

• Deployment methods → references/deployment.md
• Build configuration → references/build.md
• Pages Functions → references/functions.md
• Bindings → references/bindings.md
• Headers & Redirects → references/headers-redirects.md
• Custom domains → references/domains.md
• Wrangler CLI → references/wrangler.md

When to Use

• Deploying static sites or JAMstack applications
• Building full-stack apps with serverless functions
• Configuring Git-based CI/CD deployments
• Using Direct Upload for prebuilt assets
• Setting up preview deployments for branches/PRs
• Configuring custom domains and redirects

Deployment Methods

Quick Deploy

# Create project
npx wrangler pages project create my-project

# Deploy
npx wrangler pages deploy ./dist

# Preview deployment (branch)
npx wrangler pages deploy ./dist --branch=feature-x

Build Configuration

# Framework presets (command → output directory)
# React (Vite): npm run build → dist
# Next.js:      npx @cloudflare/next-on-pages@1 → .vercel/output/static
# Nuxt.js:      npm run build → dist
# Astro:        npm run build → dist
# SvelteKit:    npm run build → .svelte-kit/cloudflare
# Hugo:         hugo → public

Environment Variables (build-time)

Pages Functions

File-based routing in /functions directory:

/functions/index.js       → example.com/
/functions/api/users.js   → example.com/api/users
/functions/users/[id].js  → example.com/users/:id

// functions/api/hello.js
export function onRequest(context) {
  return new Response("Hello from Pages Function!");
}

Handler Types

Context Object

interface EventContext {
  request: Request;
  env: Env; // Bindings
  params: Params; // Route parameters
  waitUntil(promise: Promise<any>): void;
  next(): Promise<Response>;
  data: Record<string, any>;
}

Bindings

Access Cloudflare resources via context.env:

For detailed binding configuration, see: cloudflare-workers skill.

Headers & Redirects

Create _headers and _redirects in build output directory.

# _headers
/*
  X-Frame-Options: DENY
/static/*
  Cache-Control: public, max-age=31536000, immutable

# _redirects
/old-page /new-page 301
/blog/* https://blog.example.com/:splat

Warning: _headers and _redirects do NOT apply to Pages Functions responses.

Functions Invocation Routes

Control when Functions are invoked with _routes.json:

{
  "version": 1,
  "include": ["/api/*"],
  "exclude": ["/static/*"]
}

Wrangler Configuration

// wrangler.jsonc
{
  "name": "my-pages-app",
  "pages_build_output_dir": "./dist",
  "compatibility_date": "2024-01-01",
  "kv_namespaces": [{ "binding": "KV", "id": "<NAMESPACE_ID>" }],
  "d1_databases": [{ "binding": "DB", "database_name": "my-db", "database_id": "<ID>" }]
}

Local Development

npx wrangler pages dev ./dist

# With bindings
npx wrangler pages dev ./dist --kv=MY_KV --d1=MY_DB=<ID>

Critical Prohibitions

• Do NOT expect _headers/_redirects to apply to Pages Functions responses — attach headers in code
• Do NOT convert Direct Upload project to Git integration — not supported
• Do NOT exceed redirect limits — 2,000 static + 100 dynamic redirects max
• Do NOT use absolute URLs for proxying in _redirects — relative URLs only
• Do NOT edit bindings in dashboard when using Wrangler config — file is source of truth
• Do NOT store secrets in wrangler.toml — use dashboard or .dev.vars for local

Common Gotchas

Quick Recipes

Conditional Build Command

#!/bin/bash
if [ "$CF_PAGES_BRANCH" == "production" ]; then
  npm run build:prod
else
  npm run build:dev
fi

SPA Fallback (404.html)

Upload 404.html in build output root for SPA routing.

Disable Functions for Static Assets

// _routes.json
{
  "version": 1,
  "include": ["/api/*"],
  "exclude": ["/*"]
}
