+# Deploy on Cloudflare Workers
+
+This project can be deployed as a **Cloudflare Worker** using the **OpenNext adapter**, giving you:
+
+- Global edge deployment
+- Very low latency
+- Free `workers.dev` hosting
+- Full Next.js ISR support via R2 (optional)
+
+> **Important Windows Note:** OpenNext and Wrangler are **not fully reliable on native Windows**. Recommended options:
+>
+> - Use **GitHub Codespaces** (works perfectly)
+> - OR use **WSL (Linux)**
+>
+> Pure Windows builds may fail due to WASM file path issues.
+
+---
+
+## Prerequisites
+
+1. A **Cloudflare account** (free tier works for basic deployment)
+2. **Node.js 18+**
+3. **Wrangler CLI** installed (dev dependency is fine):
+
+```bash
+npm install -D wrangler
+```
+
+4. Cloudflare login:
+
+```bash
+npx wrangler login
+```
+
+> **Note:** A payment method is only required if you want to enable R2 for ISR caching. Basic Workers deployment is free.
+
+---
+
+## Step 1 — Install dependencies
+
+```bash
+npm install
+```
+
+---
+
+## Step 2 — Configure environment variables
+
+Cloudflare uses a different file for local testing.
+
+### 1) Create `.dev.vars` (for Cloudflare local + deploy)
+
+```bash
+cp env.example .dev.vars
+```
+
+Fill in your API keys and configuration.
+
+### 2) Make sure `.env.local` also exists (for regular Next.js dev)
+
+```bash
+cp env.example .env.local
+```
+
+Fill in the same values there.
+
+---
+
+## Step 3 — Choose your deployment type
+
+### Option A: Deploy WITHOUT R2 (Simple, Free)
+
+If you don't need ISR caching, you can deploy without R2:
+
+**1. Use simple `open-next.config.ts`:**
+
+```ts
+import { defineCloudflareConfig } from "@opennextjs/cloudflare/config"
+
+export default defineCloudflareConfig({})
+```
+
+**2. Use simple `wrangler.jsonc` (without r2_buckets):**
+
+```jsonc
+{
+  "$schema": "node_modules/wrangler/config-schema.json",
+  "main": ".open-next/worker.js",
+  "name": "next-ai-draw-io-worker",
+  "compatibility_date": "2025-12-08",
+  "compatibility_flags": ["nodejs_compat", "global_fetch_strictly_public"],
+  "assets": {
+    "directory": ".open-next/assets",
+    "binding": "ASSETS"
+  },
+  "services": [
+    {
+      "binding": "WORKER_SELF_REFERENCE",
+      "service": "next-ai-draw-io-worker"
+    }
+  ]
+}
+```
+
+Skip to **Step 4**.
+
+---
+
+### Option B: Deploy WITH R2 (Full ISR Support)
+
+R2 enables **Incremental Static Regeneration (ISR)** caching. Requires a payment method on your Cloudflare account.
+
+**1. Create an R2 bucket** in the Cloudflare Dashboard:
+
+- Go to **Storage & Databases → R2**
+- Click **Create bucket**
+- Name it: `next-inc-cache`
+
+**2. Configure `open-next.config.ts`:**
+
+```ts
+import { defineCloudflareConfig } from "@opennextjs/cloudflare/config"
+import r2IncrementalCache from "@opennextjs/cloudflare/overrides/incremental-cache/r2-incremental-cache"
+
+export default defineCloudflareConfig({
+  incrementalCache: r2IncrementalCache,
+})
+```
+
+**3. Configure `wrangler.jsonc` (with R2):**
+
+```jsonc
+{
+  "$schema": "node_modules/wrangler/config-schema.json",
+  "main": ".open-next/worker.js",
+  "name": "next-ai-draw-io-worker",
+  "compatibility_date": "2025-12-08",
+  "compatibility_flags": ["nodejs_compat", "global_fetch_strictly_public"],
+  "assets": {
+    "directory": ".open-next/assets",
+    "binding": "ASSETS"
+  },
+  "r2_buckets": [
+    {
+      "binding": "NEXT_INC_CACHE_R2_BUCKET",
+      "bucket_name": "next-inc-cache"
+    }
+  ],
+  "services": [
+    {
+      "binding": "WORKER_SELF_REFERENCE",
+      "service": "next-ai-draw-io-worker"
+    }
+  ]
+}
+```
+
+> **Important:** The `bucket_name` must exactly match the name you created in the Cloudflare dashboard.
+
+---
+
+## Step 4 — Register a workers.dev subdomain (first-time only)
+
+Before your first deployment, you need a workers.dev subdomain.
+
+**Option 1: Via Cloudflare Dashboard (Recommended)**
+
+Visit: https://dash.cloudflare.com → Workers & Pages → Overview → Set up a subdomain
+
+**Option 2: During deploy**
+
+When you run `npm run deploy`, Wrangler may prompt:
+
+```
+Would you like to register a workers.dev subdomain? (Y/n)
+```
+
+Type `Y` and choose a subdomain name.
+
+> **Note:** In CI/CD or non-interactive environments, the prompt won't appear. Register via the dashboard first.
+
+---
+
+## Step 5 — Deploy to Cloudflare
+
+```bash
+npm run deploy
+```
+
+What the script does:
+
+- Builds the Next.js app
+- Converts it to a Cloudflare Worker via OpenNext
+- Uploads static assets
+- Publishes the Worker
+
+Your app will be available at:
+
+```
+https://<worker-name>.<your-subdomain>.workers.dev
+```
+
+---
+
+## Common issues & fixes
+
+### `You need to register a workers.dev subdomain`
+
+**Cause:** No workers.dev subdomain registered for your account.
+
+**Fix:** Go to https://dash.cloudflare.com → Workers & Pages → Set up a subdomain.
+
+---
+
+### `Please enable R2 through the Cloudflare Dashboard`
+
+**Cause:** R2 is configured in wrangler.jsonc but not enabled on your account.
+
+**Fix:** Either enable R2 (requires payment method) or use Option A (deploy without R2).
+
+---
+
+### `No R2 binding "NEXT_INC_CACHE_R2_BUCKET" found`
+
+**Cause:** `r2_buckets` is missing from `wrangler.jsonc`.
+
+**Fix:** Add the `r2_buckets` section or switch to Option A (without R2).
+
+---
+
+### `Can't set compatibility date in the future`
+
+**Cause:** `compatibility_date` in wrangler config is set to a future date.
+
+**Fix:** Change `compatibility_date` to today or an earlier date.
+
+---
+
+### Windows error: `resvg.wasm?module` (ENOENT)
+
+**Cause:** Windows filenames cannot include `?`, but a wasm asset uses `?module` in its filename.
+
+**Fix:** Build/deploy on Linux (WSL, Codespaces, or CI).
+
+---
+
+## Optional: Preview locally
+
+Preview the Worker locally before deploying:
+
+```bash
+npm run preview
+```
+
+---
+
+## Summary
+
+| Feature | Without R2 | With R2 |
+|---------|------------|---------|
+| Cost | Free | Requires payment method |
+| ISR Caching | No | Yes |
+| Static Pages | Yes | Yes |
+| API Routes | Yes | Yes |
+| Setup Complexity | Simple | Moderate |
+
+Choose **without R2** for testing or simple apps. Choose **with R2** for production apps that need ISR caching.
