Rustifying Vite: Designing a Hybrid Toolchain for the Real World

Vite is a next-generation build tool that leverages native ES modules for improved performance. It eliminates the need for bundling and improves hot module replacement. Vite provides an opinionated default configuration while still allowing advanced customization through plugins. It is framework agnostic and can be used for React and other applications. Vite is being adopted by Next.js and Create React App, and integration with Nuxt 3 offers significant speed improvements.

Nux3 has made significant improvements in performance, output optimization, and serverless support. Nuxt Bridge brings the Nitro engine for enhanced performance and easier transition between Nuxt 2 and Nuxt Read. Nuxt 3 supports Webpack 5, Bytes, and Vue 3. NextLab has developed brand new websites using Docus technology. Nuxt.js is recommended for building apps faster and simpler, and Nuxt 2 should be used before migrating to Nuxt 3 for stability. DOCUS is a new project that combines Nuxt with additional features like content modules and an admin panel.

Today's Talk discusses the future of performance tooling, focusing on user-centric, actionable, and contextual approaches. The introduction highlights Adi Osmani's expertise in performance tools and his passion for DevTools features. The Talk explores the integration of user flows into DevTools and Lighthouse, enabling performance measurement and optimization. It also showcases the import/export feature for user flows and the collaboration potential with Lighthouse. The Talk further delves into the use of flows with other tools like web page test and Cypress, offering cross-browser testing capabilities. The actionable aspect emphasizes the importance of metrics like Interaction to Next Paint and Total Blocking Time, as well as the improvements in Lighthouse and performance debugging tools. Lastly, the Talk emphasizes the iterative nature of performance improvement and the user-centric, actionable, and contextual future of performance tooling.

Evan Yeo discusses Vite's growth, challenges with dependencies like ES Build and Rollup, and the creation of the bundler Rolldown. The JavaScript ecosystem faces fragmentation, but the company aims for a unified JavaScript stack. Rust is chosen for lower-level development, while JavaScript and TypeScript for high-level APIs. Roldown offers advanced bundling features, outperforming existing tools. Integration with Vite leads to tailored optimizations and significant speed improvements. Vite+ development focuses on creating a comprehensive toolkit. VitePlus integrates TS-down for library bundling, ViteTest for testing, and OX-Lint for linting. Future plans include monorepo awareness, build orchestration, and framework-like features.

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.

This talk is a ten-year retrospective into the growth of the Vue.js framework as an open-source project. It highlights the challenges faced by open-source developers, the importance of finding balance and managing scope, and the collaborative nature of the Vue community. The talk also discusses the development of Vite as a build tool and the vision for a unified JavaScript toolchain. It emphasizes the need for community alignment, contributions, and testing, while acknowledging the challenges of bad actors in the open-source community.
