+# Cloudflare Pages Frontend
+
+> [!warning] Notice
+> Choose one of the following methods
+
+## Deploy Worker with Frontend Assets
+
+Refer to [Deploy Worker](/en/guide/cli/worker#deploy-worker-with-frontend-optional)
+
+## Separate Frontend and Backend Deployment
+
+The first deployment will prompt you to create a project. For the `production` branch, enter `production`.
+
+```bash
+cd frontend
+pnpm install
+cp .env.example .env.prod
+```
+
+Modify the `.env.prod` file.
+
+Change `VITE_API_BASE` to the `worker` `url` created in the previous step. Do not add `/` at the end.
+
+For example: `VITE_API_BASE=https://xxx.xxx.workers.dev`
+
+```bash
+pnpm build --emptyOutDir
+# The first deployment will prompt you to create a project, for production branch enter production
+pnpm run deploy
+```
+
+After deployment, you can see your project in the Cloudflare console. You can configure a custom domain for `pages`.

+
+## Forward Backend Requests Through Page Functions
+
+Forwarding requests from page functions to the worker backend can achieve faster response times.
+
+The first deployment will prompt you to create a project. For the `production` branch, enter `production`.
+
+If your worker backend name is not `cloudflare_temp_email`, please modify `pages/wrangler.toml`.
+
+```bash
+cd frontend
+pnpm install
+# If you want to enable Cloudflare Zero Trust, you need to use pnpm build:pages:nopwa to disable caching
+pnpm build:pages
+cd ../pages
+pnpm run deploy
+```
