Yo devs, 兄弟姐妹们，ребята – serverless ain’t just a buzzword anymore. It’s how we roll. Infrastructure? Nah fam, that’s a 2010s problem. Cloudflare’s stack lets you drop code at the edge and scale it like mad without babysitting servers. 💅
🔧 Core Bits: Workers & Pages
Cloudflare Workers – это edge-функции, что запускаются в ответ на HTTP-запросы или по расписанию. 超快，无需冷启动。Think AWS Lambda but lightweight and global by default.
Pages – это не просто для хостинга статики. Nah, mate – it’s full-stack ready. You’ve got Pages Functions, so you can ship entire apps with logic at the edge. Sick.
🛢 Serverless Data Stack
🧠 D1 = SQL at the Edge
SQLite-powered, D1 hits that sweet spot between simplicity and power. Define your schema with migrations, bind it via wrangler.toml, and just go. Поддерживает стандартные SQL-фичи, типа индексов и ключей. 超方便。
🔧 Pro move: Use it for user data, relational stuff, and anything you want tight control over.
🔑 KV = Global Cache Beast
KV 是一个全局分布式的 key-value 存储。Use it for configs, feature flags, sessions, cache – dead simple API (get, put, etc). Идеально для быстрого доступа к данным, когда важна скорость.
🌎 Global AF. You write in Tokyo, read in Paris – 低延迟，无压力。
🪣 R2 = S3 but Cheaper
Cloudflare’s R2 = object storage, S3-compatible. 图片、PDF、视频？Throw ‘em in a bucket. No egress fees, fam. That’s major. 📉💸
Идеально для heavy static files, backup dumps, and serving media through Workers.
🔁 Queues + Durable Objects = Async Brilliance
📬 Queues = Background Processing Made Easy
Say you’re resizing images, sending emails, crunching AI – you don’t wanna block HTTP requests. Put that junk in a Queue. 消息批量处理，эффективно, масштабируемо.
👷 Workers consume from the queue, so your app stays lean and fast.
🧍 Durable Objects = Single Instance Global State
Imagine: a single chat room, a live game lobby, collab whiteboards. Durable Objects are your mates here. Они обеспечивают уникальный экземпляр с сохранением состояния. WebSocket ready, no sweat. 🌐💬
Can persist data too – lowkey brilliant.
🧠 Workers AI = AI Models on Tap
你可以在 Cloudflare Workers 里直接调用 AI 模型 – translation, classification, summarisation, you name it. Никакой лишней возни – just bind and invoke. 🤖
🔥 Models like @cf/meta/llama-3 or @cf/openai/whisper are just one config away.
🛠 Dev Experience: Wrangler & C3
npm create cloudflare– spins up Workers or Pages fast.- Wrangler – your CLI BFF. Create, deploy, bind, log, test, migrate – всё в одном.
Use npm run dev to test locally. Want E2E confidence? Slide in with Vitest or Playwright.
🤖 CI/CD Vibes: Git + Actions = Magic Deployments
Hook your repo to Cloudflare. Every push = preview or prod deploy. No hands needed. Need more? GitHub Actions can run migrations, deploy Workers, update KV – automagically. ✨
🚀 Going Prod? Don’t Slack:
- Domains: Tie in custom domains easily.
- Monitoring: Dashboard gives request/error stats. Logs (beta) = gold for debugging.
- Security: WAF, Bot Fight Mode, Access Policies = locked down.
- Perf: Caching rules, Brotli compression, smart routing = blazing fast apps.
🧘♂️ Final Thoughts
Cloudflare’s serverless stack is honestly the dream for fullstack devs. Want a real-time AI-powered chat app that scales like mad and costs peanuts? Do it. Want a static blog with edge auth and caching? Sorted.
🧑💻 Build smarter. Ship faster. Scale globally. No infra anxiety.
