No REST for Cap'n Web

Top Content

Kenton Varda

Cloudflare

Kenton Varda advocates for using CapnWeb, an RPC protocol, over REST for web APIs, emphasizing benefits for humans and AI agents. CapnWeb simplifies client-server communications by treating them as function calls. TypeScript type checking ensures method accuracy in CapnWeb across JavaScript runtimes. Stubs in CapnWeb allow method calls to execute on remote objects and simulate all possible method names for remote calls. Converting REST APIs to CapnWeb streamlines code and improves API calls. CapnWeb enhances API functionality with object-specific RPC sessions and promises pipelining for multilevel API optimization. AI agent security challenges are addressed with sandboxing and token protection in CapnWeb. CapnWeb capabilities for AI agents include passing restricted CapnWeb stubs and exploring capability-based security with CapnProto.

The Good, The Bad, and The Web Components

Top Content

Zach Leatherman

Eleventy (11ty) Creator

Web Components are a piece of reusable UI enabled by web standards and built into the web platform. They offer the potential for faster component initialization and less library overhead. Web Components can be created from scratch and utilized with existing component libraries. Shadow DOM and Declarative Shadow DOM provide benefits such as scoped CSS and server-rendered components. The tradeoff between not repeating oneself and achieving full server-side rendering support is discussed. User experience is deemed more important than developer experience.

Welcome to this talk on domain-driven design in Vue.js application. Today we are going to look into domain-driven design, its benefits and how it works with Vue.js domain-driven design versus the MVVM model. Vue.js thrives in domain-driven design, a design approach that models software to match a domain. DDD emphasizes understanding business logic and creating a domain that reflects the language and concepts. Integrating DDD in Vue.js offers benefits such as effective modeling of complex business domains, structured code reflecting domain logic, and easier onboarding and ownership.

Robert Nagy

Technical Steering Committee Member @nodejs

The Talk discusses the current state of the Node HTTP client and the problems it faces, including the lack of support for HTTP pipelining and the intrinsic link between request and response objects. The speaker introduces the library Indichy, which aims to provide a more user-friendly API for HTTP in Node. The Talk highlights the performance advantages of using WebAssembly in the Umidigi HTTP client and the plans to include it in Node Core. The speaker also mentions the support for signals and the ability to post requests in Umidigi. Additionally, the Talk covers the customization options in Undici, the different types of dispatchers available, and the potential inclusion of Indichy in Node Core. Future plans include support for HTTP 2 and 3, DNS lookup enhancements, and improvements to fetch and pool scheduling. The Talk concludes by discussing the differences in TCP implementations across operating systems and the considerations for adding Web APIs and standards to Node Core.

Tejas Kumar

Author of the "Fluent React" bestselling book, software engineer with 23 years of experience, and host of the developer-loved ConTejas Code podcast.

This Talk explores React's internal jargon, specifically fiber, which is an internal unit of work for rendering and committing. Fibers facilitate efficient updates to elements and play a crucial role in the reconciliation process. The work loop, complete work, and commit phase are essential steps in the rendering process. Understanding React's internals can help with optimizing code and pull request reviews. React 18 introduces the work loop sync and async functions for concurrent features and prioritization. Fiber brings benefits like async rendering and the ability to discard work-in-progress trees, improving user experience.
