| Faster Builds and Fewer Headaches with Modern JavaScript Tooling | Alexander Lichter | 32m |
Vite becomes the shared dev layer while Rolldown replaces multiple bundlers to give 3–16× production build speedups and simpler chunking; Oxc (the Oxidation… | ||
| Beyond Build Orchestration: What It Takes to Build Modern JavaScript Monorepos | Victor Savkin | 32m |
Nx is a monorepo platform that couples task orchestration with developer UX: a terminal UI that visualizes targets and pins outputs, deep editor plugins that… | ||
| The New User Interaction Model | Kent C. Dodds | 35m |
Argues that the integration problem is solved by Model Context Protocol so agents can actually perform real-world tasks rather than just answer questions… | ||
| Beyond Signals | Ryan K Carniato | 34m |
Claims that signals plus a reactive data graph remove the VDOM and let updates hit only changed fields, demonstrated by nested async fetches that each take 2s… | ||
| SSR with Micro-Frontends: How Composition Works with Modern Frameworks | Luca Mezzalira | 35m |
Claims that server-side micro-frontends work with existing frameworks using concrete patterns: Astro.js server islands, Next.js multi-zones, and Module… | ||
