Miguel Ángel 621ddd4693 fix(studio): stop file names with %, apostrophes or $ from breaking Studio (#5156)
* fix(studio): serve files whose name has a bare percent sign

A browser sends src="100%.png" with the % unescaped, and decoding the whole path threw, so Studio answered 500. Only well-formed escapes are decoded now.

* fix(cli): serve files with a bare percent sign from the check and snapshot server

One shared decode rule for request paths; the image thumbnail route's malformed-escape 400 could no longer fire, so a name that is not a file is a 404.

* fix(cli): name a failed file with a bare percent sign in check

* fix(studio): keep apostrophes and dollar signs in file names when editing attributes

An attribute value is matched by its own quote kind, so src="it's.png" is replaced instead of duplicated, and every insert uses a function replacer, so $1 or $& in a file name is written as is.

* fix(studio): rename references spelled with %20 or & and read quoted media sources

WIP: not yet tested; see the resume note.

* fix(studio): match whole attribute names when editing media sources

* fix(studio): compare decoded names and escape replacement references

* fix(studio): preserve file references across URL and string consumers

* docs: clarify raw file references and URL fields

* fix(studio): keep raw path identity distinct from URL spelling

* fix: share attribute grammar and decode media URLs at their readers

* fix: preserve local filename identity in HTML URL output

* fix: decode entity references before rename candidate matching

* style: format rename entity handling and regressions

* fix: preserve platform file identity when renaming references

* fix(core): decode CSS escapes before rebasing asset URLs

* fix(core): consume CSS continuations before URL encoding

* fix(core): preserve CSS URL identity and escape rebased suffixes

* fix(core): express CSS suffix controls with Unicode categories

* fix(core): preserve URL backslash identity while rebasing

* test(core): respect platform backslash filename semantics

* fix(studio): a dropped file with %, # or ? in its name loads, and an encoded reference renames

* fix(studio): read an authored src as a URL so dropped files with spaces, %, # or ? load

* fix(studio): media routes find files named with ? or #, and the probe reads a src as a URL

* fix(studio-server): one rule for request file paths, so loudness finds files named with %, # or ?

* chore: drop the design note from the change

* fix(core): rename replaced clips whose src is URL-encoded

@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
