Cloudflare

This 3 hour workshop will provide an introduction to the Cloudflare Developer Platform for application developers. It will focus on developing a full-stack React application backed by tests that can guarantee the correctness of its interactions with the resources and APIs provided by the Developer Platform.The workshop assumes basic knowledge of TypeScript and React — not much beyond what’s needed to build a hello world app in React using TypeScript! Knowledge of the Developer Platform is also not required as everything Cloudflare related will be introduced as part of the workshop.So if you’re interested in application development on the (fast and inexpensive!) Cloudflare platform then this workshop is for you. By the end of it you will know how to build a fully-fledged, fully-tested, full-stack web application (using React or any framework of your choice) with a comprehensive testing structure that gives you full confidence and peace of mind.
AgendaThe workshop will include live coding, Q&A, and interactive coding sections. The starting code, alongside instructions will be also made available for participants to revisit and dig deeper afterthe workshop.As part of the initial setup we’ll see how to use the C3 tool to easily deploy applications to Cloudflare in a matter of minutes.Afterwards, we will see how to write code that interacts with the Developer Platform specific resources and APIs, specifically, we’ll use KVs, R2 buckets and Workers AI. We’ll also make sure to test all the code to make sure that it correctly interacts with the aforementioned APIs via the official Workers Vitest integration.We will then integrate the Workers code with our React app to build a complete full-stack application ready to be deployed to the Cloudflare edge network. We will use playwright to implement an end-to-end (e2e) suite of tests to make sure that the application integrates perfectly with the Cloudflare platform.
Takeaways- How to develop on the Cloudflare Workers runtime and interact with various Cloudflare resources- How to develop, comprehensively test and deploy a full-stack application on the Cloudflare Platform

In this workshop, we discuss the merits of serverless architecture and how it can be applied to the AI space. We'll explore options around building serverless RAG applications for a more lambda-esque approach to AI. Next, we'll get hands on and build a sample CRUD app that allows you to store information and query it using an LLM with Workers AI, Vectorize, D1, and Cloudflare Workers.

The developer ecosystem is always moving fast and this year has proved no exception. React Server Components can offer a significant improvement to developer experience and to application performance. But I think it's fair to say that this new server-first paradigm can be tricky to wrap your head around!In the first half of this workshop, we'll explore React Server Components from the ground-up: building our own mini meta-framework to help us understand how RSCs work. We'll discover exactly what is produced by an RSC build and we'll connect those pieces together to form a full application.Next, we'll deploy it! Cloudflare have also had a busy year too — Smart Placement, in particular, is a new technology that we've developed which fits the RSC model perfectly. We'll explore why that makes sense for our workshop app, and we'll actually deploy it onto the Cloudflare Developer Platform.Finally, we'll build out our app a little further, using D1 (our serverless SQL database) to really show off the React Server Component's power when combined with Smart Placement.You should come away from this workshop with a greater understanding of how React Server Components work (both behind-the-scenes and also how you as a developer can use them day-to-day), as well as insight into some of the new deployment patterns that are now possible after recent innovations in the platform space.
