terencechoandClaude Opus 4.8 f98b8ead37 fix(studio): guard import.meta.env reads so the player survives non-Vite ESM hosts (#3948)
In non-Vite ESM hosts, import.meta.env is undefined and direct reads crash at module load.

Guard both player reads with optional chaining. Existing Vite defaults are unchanged.

Reject future unguarded import.meta.env property access in either module.

@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 19, Zustand 4/5 (state management; development uses Zustand 5)
  • CodeMirror 6 (editor)
  • Tailwind CSS (styling)
  • Vite (bundler)
  • Phosphor Icons
