Miguel Ángel c0ffdc0fb0 fix(core,studio): escape user values in querySelector attribute selectors
Extract cssAttrSelector to packages/core/src/utils/cssSelector.ts and
use it (or CSS.escape for browser-side code) at all 12 sites that
previously interpolated raw user-authored values into querySelector
attribute selectors. A " in a composition ID, script src, or
data-start value would produce a malformed selector that throws.

Node-side (core compiler/parser): uses the shared cssAttrSelector.
Browser-side (runtime, studio): uses native CSS.escape().

Supersedes #1568 which fixed only the 3 bundler sites.

@hyperframes/studio

Browser-based composition editor UI for Hyperframes. Provides a visual timeline, code editor, and live preview for building video compositions.

Install

npm install @hyperframes/studio

What it does

The studio is a React application with:

  • Visual timeline — drag, resize, and arrange elements on tracks
  • Code editor — edit HTML and GSAP scripts with CodeMirror (syntax highlighting, autocomplete)
  • Live preview — see changes in real time as you edit
  • Composition inspector — view and modify element properties

Development

The studio is embedded in the hyperframes preview command. To develop the studio UI itself:

cd packages/studio
bun run dev        # Start Vite dev server
bun run build      # Build for production
bun run typecheck  # Type-check

Tech stack

  • React 18/19, Zustand (state management)
  • CodeMirror 6 (editor)
  • Tailwind CSS (styling)
  • Vite (bundler)
  • Phosphor Icons
