2024 年 Developer Week 已正式閉幕。上週的每一天，我們都會發布新產品和功能，旨在為開發人員提供在 Cloudflare 上建置完整堆疊應用程式所需的元件。
儘管 Developer Week 現已結束，但我們仍將繼續與在我們平台上建置的超過 200 萬開發人員一起創新。建立一個平台令人興奮，但我們對開發人員在平台上構建的產品同樣充滿期待。在我們深入回顧這些公告之前，作為對活動週的告別，我們想分享一些公司如何使用 Cloudflare 來支援他們的應用程式：
我們一直在使用 Workers 透過 R2 進行影像傳輸，並且在實施一年後能夠保持穩定運作。部署的速度和詳細設定的靈活性大大減少了傳統伺服器管理所需的時間和精力。特別是，我們看到了顯著的成本節省，並對 Cloudflare Workers 提供的支援深表感謝。- FAN Communications
Milkshake 幫助創作者、影響者和企業主直接從手機建立引人入勝的網頁，以簡單且富有創意的方式宣傳他們的專案和熱情。Cloudflare 幫助我們透過 R2 快速且經濟地遷移資料。我們使用 Workers 作為使用者網站與其影像和資產之間的路由層，並以經濟實惠的方式建立個人化的分析產品。Cloudflare 在不斷創新，這讓我們能夠以其他開發人員平台成本的一小部分執行基礎架構，並且我們一直在熱切地等待 D1 和 Queues 的更新，以便隨著產品的不斷成長可持續擴展 Milkshake。- Milkshake

| Announcement | Summary |
|---|---|
| Making state easy with D1 GA, Hyperdrive, Queues and Workers Analytics Engine updates | A core part of any full-stack application is storing and persisting data! We kicked off the week with announcements that help developers build stateful applications on top of Cloudflare, including making D1, Cloudflare’s SQL database and Hyperdrive, our database accelerating service, generally available. |
| Building D1: a Global Database | D1, Cloudflare’s SQL database, is now generally available. With new support for 10GB databases, data export, and enhanced query debugging, we empower developers to build production-ready applications with D1 to meet all their relational SQL needs. To support Workers in global applications, we’re sharing a sneak peek of our design and API for D1 global read replication to demonstrate how developers scale their workloads with D1. |
| Why Workers environment variables contain live objects | Bindings don't just reduce boilerplate. They are a core design feature of the Workers platform which simultaneously improve developer experience and application security in several ways. Usually these two goals are in opposition to each other, but bindings elegantly solve for both at the same time. |

| Announcement | Summary |
|---|---|
| Leveling up Workers AI: General Availability and more new capabilities | We made a series of AI-related announcements, including Workers AI, Cloudflare’s inference platform becoming GA, support for fine-tuned models with LoRAs, one-click deploys from HuggingFace, Python support for Cloudflare Workers, and more. |
| Running fine-tuned models on Workers AI with LoRAs | Workers AI now supports fine-tuned models using LoRAs. But what is a LoRA and how does it work? In this post, we dive into fine-tuning, LoRAs and even some math to share the details of how it all works under the hood. |
| Bringing Python to Workers using Pyodide and WebAssembly | We introduced Python support for Cloudflare Workers, now in open beta. We've revamped our systems to support Python, from the Workers runtime itself to the way Workers are deployed to Cloudflare’s network. Learn about a Python Worker's lifecycle, Pyodide, dynamic linking, and memory snapshots in this post. |
概述
| Announcement | Summary |
|---|---|
| R2 adds event notifications, support for migrations from Google Cloud Storage, and an infrequent access storage tier | We announced three new features for Cloudflare R2: event notifications, support for migrations from Google Cloud Storage, and an infrequent access storage tier. |
| Data Anywhere with Pipelines, Event Notifications, and Workflows | We’re making it easier to build scalable, reliable, data-driven applications on top of our global network, and so we announced a new Event Notifications framework; our take on durable execution, Workflows; and an upcoming streaming ingestion service, Pipelines. |
| Improving Cloudflare Workers and D1 developer experience with Prisma ORM | Together, Cloudflare and Prisma make it easier than ever to deploy globally available apps with a focus on developer experience. To further that goal, Prisma ORM now natively supports Cloudflare Workers and D1 in Preview. With version 5.12.0 of Prisma ORM you can now interact with your data stored in D1 from your Cloudflare Workers with the convenience of the Prisma Client API. Learn more and try it out now. |
| How Picsart leverages Cloudflare's Developer Platform to build globally performant services | Picsart, one of the world’s largest digital creation platforms, encountered performance challenges in catering to its global audience. Adopting Cloudflare's global-by-default Developer Platform emerged as the optimal solution, empowering Picsart to enhance performance and scalability substantially. |
藉助 D1 GA 版以及 Hyperdrive、Queues 和 Workers Analytics Engine 更新簡化現狀
| Announcement | Summary |
|---|---|
| Announcing Pages support for monorepos, wrangler.toml, database integrations and more! | We launched four improvements to Pages that bring functionality previously restricted to Workers, with the goal of unifying the development experience between the two. Support for monorepos, wrangler.toml, new additions to Next.js support and database integrations! |
| New tools for production safety — Gradual Deployments, Stack Traces, Rate Limiting, and API SDKs | Production readiness isn’t just about scale and reliability of the services you build with. We announced five updates that put more power in your hands – Gradual Deployments, Source mapped stack traces in Tail Workers, a new Rate Limiting API, brand-new API SDKs, and updates to Durable Objects – each built with mission-critical production services in mind. |
| What’s new with Cloudflare Media: updates for Calls, Stream, and Images | With Cloudflare Calls in open beta, you can build real-time, serverless video and audio applications. Cloudflare Stream lets your viewers instantly clip from ongoing streams. Finally, Cloudflare Images now supports automatic face cropping and has an upload widget that lets you easily integrate into your application. |
| Cloudflare Calls: millions of cascading trees all the way down | Cloudflare Calls is a serverless SFU and TURN service running at Cloudflare’s edge. It’s now in open beta and costs $0.05/ real-time GB. It’s 100% anycast WebRTC. |
任何完整堆疊應用程式的核心部分都是儲存和持久化資料！我們以一系列公告拉開了活動週的序幕，包括讓 D1（Cloudflare 的 SQL 資料庫）和 Hyperdrive（我們的資料庫加速服務）正式上市，可幫助開發人員基於 Cloudflare 構建具狀態應用程式。

| Cloudflare acquires PartyKit to allow developers to build real-time multi-user applications | We announced that PartyKit, a trailblazer in enabling developers to craft ambitious real-time, collaborative, multiplayer applications, is now a part of Cloudflare. This acquisition marks a significant milestone in our journey to redefine the boundaries of serverless computing, making it more dynamic, interactive, and, importantly, stateful. |
| Blazing fast development with full-stack frameworks and Cloudflare | Full-stack web development with Cloudflare is now faster and easier! You can now use your framework’s development server while accessing D1 databases, R2 object stores, AI models, and more. Iterate locally in milliseconds to build sophisticated web apps that run on Cloudflare. Let’s dev together! |
| We've added JavaScript-native RPC to Cloudflare Workers | Cloudflare Workers now features a built-in RPC (Remote Procedure Call) system for use in Worker-to-Worker and Worker-to-Durable Object communication, with absolutely minimal boilerplate. We've designed an RPC system so expressive that calling a remote service can feel like using a library. |
| Community Update: empowering startups building on Cloudflare and creating an inclusive community | We closed out Developer Week by sharing updates on our Workers Launchpad program, our latest Developer Challenge, and the work we’re doing to ensure our community spaces – like our Discord and Community forums – are safe and inclusive for all developers. |

Cloudflare 的 SQL 資料庫 D1 現已正式上市。透過對 10GB 資料庫、資料匯出和增強查詢偵錯的全新支援，我們讓開發人員能夠使用 D1 構建生產就緒應用程式，從而滿足所有關聯式 SQL 需求。為了在全球應用程式中支援 Workers，我們分享了用於 D1 全球讀取複製的設計和 API 的先行預覽，以示範開發人員如何使用 D1 擴展工作負載。
繫結不僅僅會減少樣板。它們是 Workers 平台的核心設計功能，可以透過數種方式同時改進開發人員體驗和應用程式安全性。這兩個目標通常是相互對立的，但繫結可以輕鬆地同時解決這兩個問題。
