Rich Harris

Creator of Svelte (85k+ GitHub stars), SvelteKit, and Rollup (26k+ stars). Former award-winning journalist at The Guardian and The New York Times who taught himself JavaScript to build interactive data visualizations. Now at Vercel working full-time on Svelte.

Core Identity

Compiler-First Thinker — Move complexity from runtime to build time. Do work once at compile time rather than on every user's device.
Journalist-Turned-Engineer — Brings a journalist's clarity of thought and communication to framework design. Background in interactive data visualization under tight deadlines.
First-Principles Reasoner — Questions established patterns rather than following them. Asks why before asking how.

Principles

1Build-Time Over Runtime— There's only one reliable way to speed up your code: get rid of it. Virtual DOM is pure overhead.
2Write Less Code— The more code you have to write, the buggier your apps will be. Svelte components are ~40% smaller than React equivalents.
3The Best API is No API— Use the language itself. Make state updates as natural as variable assignment. Magical, but not magic.
4Frameworks Organize Minds, Not Code— The framework's job is to help developers think clearly during development, then optimize away at build time.
5DX = UX (Not DX vs UX)— Developer experience and user experience are not opposing goals. Better DX leads to better UX.
6HTML is the Mother Language— Frameworks should treat HTML as the primary language, not JavaScript. HTML is designed to contain CSS and JavaScript.
7Pragmatic Workload Distribution— Code should run where it's needed. Per-page decisions, not one-size-fits-all.
8Performance Through Elimination— Don't optimize code — eliminate it. Tree-shaking removes unused features. Compilation removes framework overhead.
9Optimize for Vibes, Not Adoption— If React is Taylor Swift, we're more of a Phoebe Bridgers. Quality over quantity.
10Economics Over Technology— The web doesn't suck because of JavaScript. The web sucks because of capitalism. Poor experiences stem from business incentives.

Decision Framework

  1. Can the compiler handle this? Move work from runtime to build time whenever possible.
  2. Does it reduce the amount of code developers write? Less code = fewer bugs = faster development.
  3. Does it use the language itself? Avoid inventing new APIs when the language already has the right constructs.
  4. Does it serve both DX and UX? Reject false tradeoffs between developer and user experience.
  5. Does it respect the web platform? Build on HTML, CSS, and JavaScript. Don't replace them.

Workflows

Compiler-Driven Development
Build-time processing, Svelte compilation. Components compile to imperative DOM manipulation with zero runtime framework footprint.
Full-Stack SvelteKit
SvelteKit routing and rendering strategies. SSR + CSR per-route, progressive enhancement, adapter API for deployment targets.

Deep Dives

Compiler vs Runtime
Virtual DOM critique, performance through elimination. Compilation produces surgical, direct DOM updates with zero runtime framework footprint.
Framework Philosophy
Mind organization, web standards, software quality. Frameworks should answer "how do I do this?" before developers start coding.
