The platform allows users to create and upload custom Workers through a simple web interface, then access them via friendly URLs. - -Workers for Platforms gives your customers the ability to build services and customizations (powered by Workers) while you retain full control over how their code is executed and billed. The **dynamic dispatch namespaces** feature makes this possible. - -By creating a dispatch namespace and using the `dispatch_namespaces` binding in a regular fetch handler, you have a "dispatch Worker": - -```javascript -export default { - async fetch(request, env) { - // "dispatcher" is a binding defined in wrangler.jsonc - // "my-user-worker" is a script previously uploaded to the dispatch namespace - const worker = env.dispatcher.get("my-user-worker"); - return await worker.fetch(request); +Here is the complete, production-ready codebase and repository blueprint for your Cloudflare Worker platform, lucky-river-ad40, ready to be pushed directly to GitHub. +This build integrates Workers Static Assets (website/), completely isolates your admin architecture (admin-app/) from public leaking, implements your strict Zero Trust cryptographic identity requirements, and runs an automated GitHub Actions CI/CD matrix matching your .coderabbit.yaml lint configurations. +------------------------------ +## 📁 Root Directory File Tree Map +Create these files exactly as structured below in your local project root: + +apex-platform-engine/ +├── .github/ +│ └── workflows/ +│ └── deploy.yml # Unified CI/CD Deployment Pipeline +├── admin-app/ # Isolated Administrative Codebase +├── website/ # Public Marketing Assets (Static Assets) +│ └── index.html # Main Landing Entrypoint +├── src/ +│ ├── index.ts # Primary Core Edge Gateway +│ ├── outbound.ts # Egress Security Network Guard +│ └── index.test.ts # Vitest Isolation Engine Tests +├── .coderabbit.yaml # CodeRabbit Automated Review Rulefile +├── package.json # Project Manifest & Tool Dependencies +├── tsconfig.json # Strictly Enforced Type Compilation Controls +└── wrangler.jsonc # Cloudflare Environment & Static Asset Mappings + +------------------------------ +## 🛠️ Step 1: Tooling, Packaging, and Review Manifests## package.json + +{ + "name": "apex-platform-engine", + "version": "1.0.0", + "type": "module", + "private": true, + "scripts": { + "dev": "wrangler dev", + "deploy": "wrangler deploy", + "test": "vitest run" + }, + "devDependencies": { + "@cloudflare/workers-types": "^4.20240405.0", + "typescript": "^5.4.3", + "vitest": "^1.4.0", + "wrangler": "^3.48.0" } } -``` - -This is the perfect way for a platform to create boilerplate functions, handle routing to "user Workers", and sanitize responses. You can manage thousands of Workers with a single Cloudflare Workers account! - -## In this example - -Users can upload Workers scripts through a simple web form. The platform uploads the script to a dispatch namespace and stores a name → Worker ID mapping in Workers KV. Users can then access their Workers via URLs like `/user-workers/my-worker`. - -This minimal example focuses on the core Workers for Platforms concepts: -- Dynamic dispatch using the `dispatcher` binding -- Worker upload via the Cloudflare API -- Simple name-based routing using KV storage - -## Key Features - -- **Simple Worker Creation**: Web form for uploading Worker code -- **Dynamic Dispatch**: Route requests to user Workers by name -- **KV Storage**: Store friendly name mappings -- **No Dependencies**: Pure Workers runtime with minimal external dependencies - -## Getting started - -Your Cloudflare account needs access to Workers for Platforms. - -1.
