Developer Week 2024 年正式落下帷幕。我们在上周的每一天，都会发布新的产品和功能，旨在为开发人员提供在 Cloudflare 上构建全栈应用所需的组件。
尽管 Developer Week 现已结束，但我们仍将致力于与在我们平台上进行开发的逾两百万开发人员一起持续创新。建立平台的乐趣在于看开发人员在其上构建的内容。在回顾本周的公告之前，在本周结束之际，我们想与大家分享几家公司使用 Cloudflare 为其应用程序提供支持的方式：
我们始终在使用 Workers 进行 R2 的镜像交付，并在实施一年后仍能保持稳定运行。部署速度和详细配置的灵活性大幅降低了传统服务器管理所需的时间和精力。尤其是，我们看注意到了明显的成本节约，并对 Cloudflare Workers 提供的支持深表感谢。——FAN Communications
Milkshake 助力创作者、意见领袖和企业主直接从其的手机上创建吸引人的网页，以简单、有创意的方式推广其项目和激情。Cloudflare 借助 R2 帮助我们以快速且经济的方式迁移数据。我们使用 Workers 作为用户网站与其图片和资产之间的路由层，并以低廉的价格建立个性化的分析服务。Cloudflare 的创新使我们能够持续的、以其他开发平台成本的一小部分运行基础设施，我们一直在热切期待 D1 和Queues 的更新，我们一直在急切期待 D1 和 Queues 的更新，以持续扩展Milkshake。——Milkshake
为了确保您不会错过任何内容，以下提供上周发布的公告和深入技术探讨的简要回顾：

| 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. |
摘要
| 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. |
使用正式发布的 D1 以及 Hyperdrive、Queues 和 Workers Analytics Engine 更新，简化状态管理
| 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. |
全栈应用的核心部分是存储和保留数据！我们宣布一系列产品更新来拉开本届 Developer Week 的序幕，这些更新旨在帮助开发人员在 Cloudflare 上构建有状态的应用程序，包括正式发布 D1 和 Hyperdrive，前者是 Cloudflare 的 SQL 数据库，后者是 Cloudflare 的数据加速服务。

| Cloudflare acquires Baselime to expand serverless application observability capabilities | We announced that Cloudflare has acquired Baselime, a serverless observability company. |
| 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 数据库 D1 现已正式推出。增加对 10 GB数据库、数据导出和增强查询调试的支持，使开发人员能够利用 D1 构建准备上线的应用程序，从而满足其对关系型 SQL 的全部需求。我们分享了针对 D1 全球读取复制的设计和 API 的先行预览，以展示开发人员利用 D1 扩展其工作负载的方式，旨在为全球应用程序中的 Workers 提供支持。
绑定不仅仅是为了减少样板。 作为 Workers 平台的核心设计特性，其能够同时以多种方式改进开发人员体验和应用程序安全性。 通常这两个目标是相互对立的，但绑定能够巧妙地同时达成两者。
