Use standard asset URL pattern (new URL('./roboto.woff', import.meta.url).href)
instead of direct .woff import. This avoids Turbopack incorrectly trying to
parse the binary font file as UTF-8 JavaScript.
Changes:
- Add src/roboto-font.ts exporting font via URL API
- Update TextsHighHZ.tsx to use new font module
- Remove *.woff module declaration (no longer needed since we're not
directly importing .woff files anymore)
Fixes: utsuboco#59, utsuboco#66

Problem
When using r3f-perf with Next.js + Turbopack, the build fails with:
This happens because the original
import font from './roboto.woff'causes Turbopack to try parsing the binary font file as UTF-8 JavaScript.Relates to #59 and #66.
Solution
Use the standard asset URL pattern that all modern bundlers recognize:
This pattern works with Turbopack, webpack 5, and Vite — they resolve the
.wofffile, copy it to the output, and provide a proper URL at runtime.Changes
src/roboto-font.ts(new) — exports font usingnew URL()patternsrc/components/TextsHighHZ.tsx— imports from../roboto-fontinstead of../roboto.woffsrc/globals.d.ts— removeddeclare module '*.woff'(no longer needed since we're not importing.wofffiles directly)3 files changed, 8 insertions(+), 3 deletions(-)
Why this pattern?
troika-three-text (used by drei's
<Text>) loads fonts via a web worker with an opaque origin. Thenew URL()pattern ensures the font is accessible via HTTP URL, which works in all environments including web workers.Test plan
