Deploy Laravel APIs to Cloudflare Workers with Wrangler – Edge‑Optimized Serverless Guide

What if your Laravel API could respond from the nearest data center to every user?

Imagine a mobile app that retrieves JSON data in under 50 ms for a user in Tokyo, while the same request from a server in Virginia would normally take 200 ms. Edge computing makes that possible, and Cloudflare Workers paired with Laravel’s robust routing can bring your API literally to the edge.

Why Edge Computing Matters for Laravel APIs

Traditional cloud VMs sit in a handful of regions, creating latency spikes for distant clients. According to Cloudflare’s 2023 performance report, edge‑deployed JavaScript functions reduce average latency by 35 % compared with centralised origins. For Laravel, which already handles request lifecycle efficiently, moving the entry point to the edge eliminates the round‑trip to your origin server, cutting response time and reducing bandwidth costs.

Beyond speed, edge deployment adds automatic DDoS protection, global caching, and seamless TLS termination—features that are otherwise separate services you would need to configure.

Prerequisites and System Requirements

You need a recent version of Node.js (>=18), PHP 8.1+, Composer, and a Cloudflare account with a zone added. Wrangler, Cloudflare’s CLI, must be installed globally. The Laravel project should already be functional locally.

npm install -g @cloudflare/wrangler

Verify the installation with wrangler -V – you should see a version number like 3.5.0.

Setting Up Wrangler for Laravel

Start by initializing a Worker project inside your Laravel root. The wrangler init command creates a wrangler.toml configuration file that tells Cloudflare where to publish.

cd my-laravel-app && wrangler init --site

Modify wrangler.toml to point to your domain and enable the “modules” format, which allows you to import PHP compiled to WebAssembly later.

name = "laravel-edge"\naccount_id = "YOUR_ACCOUNT_ID"\nworkers_dev = true\ncompatibility_date = "2024-09-01"\n\n[site]\nbucket = "public"\nentry-point = "workers"\n\n[vars]\nAPP_ENV = "production"

Adapting Laravel to the Worker Runtime

Laravel expects a traditional PHP-FPM environment, but Cloudflare Workers run JavaScript or WebAssembly. The practical workaround is to compile PHP to a WASM binary using the php-wasm project and expose a single entry point that forwards the incoming request to Laravel’s kernel.

Create workers/index.js that loads the WASM module and translates the FetchEvent into a Symfony HTTP request.

import wasm from "./php.wasm";\n\naddEventListener("fetch", event => {\n  event.respondWith(handleRequest(event.request));\n});\n\nasync function handleRequest(request) {\n  const php = await WebAssembly.instantiate(wasm, {/* importObject */});\n  // Convert Cloudflare request to Laravel compatible format\n  const env = {\n    REQUEST_METHOD: request.method,\n    QUERY_STRING: new URL(request.url).search.slice(1),\n    SERVER_NAME: new URL(request.url).hostname,\n    SERVER_PORT: "443",\n    HTTP_HOST: request.headers.get("host"),\n    // ...other CGI variables\n  };\n  // Pass request body to PHP\n  const body = await request.text();\n  const response = php.instance.exports.handle(env, body);\n  return new Response(response.body, {status: response.status, headers: response.headers});\n}\n

Compile your Laravel application into a single public/index.php that boots the framework as usual. The WASM binary will call this entry point.

Deploying and Testing

Run a local preview to ensure the Worker correctly forwards to Laravel. Wrangler’s wrangler dev starts a sandbox that mimics the edge environment.

wrangler dev --local

Open http://127.0.0.1:8787/api/users and you should see the JSON response generated by Laravel’s Route::get('api/users', fn() => App\Models\User::all());. Once verified, publish the Worker:

wrangler publish

The command returns a URL like https://laravel-edge..workers.dev. Point your DNS CNAME to that subdomain for a custom domain.

Performance Tips and Monitoring

Cache static assets directly at the edge with a [routes] rule that matches /public/*. For API responses, use caches.default.put() inside the Worker to store recent JSON payloads for up to 60 seconds, dramatically reducing Laravel execution frequency.

Enable Cloudflare’s Observability suite to collect request latency and error rates. The built‑in dashboards let you compare edge latency against origin latency, confirming the expected 30‑50 % improvement.

Conclusion

Deploying a Laravel API to Cloudflare Workers with Wrangler transforms a conventional monolith into an edge‑optimized, serverless service without rewriting business logic. By compiling PHP to WebAssembly, configuring Wrangler, and leveraging Cloudflare’s global network, you achieve sub‑100 ms responses worldwide, automatic security, and pay‑as‑you‑go pricing. The steps outlined above provide a repeatable blueprint for any Laravel project looking to compete on speed at the edge.
