The live-preview engine the frontend loads is pdfium-engine.wasm, built by the
`wasm-pdfium` CMake preset (PDFENGINE_WITH_PDFIUM=ON). The reflow code is inside
`#ifdef PDFENGINE_WITH_PDFIUM`, so the `wasm` stub preset (PDFium OFF) — which
scripts/build_wasm.ps1 builds and copies to the UNUSED pdfengine.wasm — never
contained reflow at all. Result: every prior "WASM rebuilt" step updated the wrong,
reflow-less artifact, so the caret x0 fix (and center/right) never reached the browser.
Rebuilt the wasm-pdfium preset and deployed bin/pdfengine.{mjs,wasm} ->
public/pdfium-engine.{mjs,wasm} (md5 now 53d1ec9f, reflow object 631KB vs the 18KB
stub). Bumped the cache-buster so browsers fetch the new engine.
Engine .pyd + overlay-diff gate unchanged (1.70%/1.69%, render identical); the x0
change is caret-only metadata.
Follow-up: build_wasm.ps1 builds the wrong (stub) preset and deploys the wrong file.

React + TypeScript + Vite
This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
Currently, two official plugins are available:
- @vitejs/plugin-react uses Oxc
- @vitejs/plugin-react-swc uses SWC
React Compiler
The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see this documentation.
Expanding the ESLint configuration
If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
export default defineConfig([
globalIgnores(['dist']),
{
files: ['**/*.{ts,tsx}'],
extends: [
// Other configs...
// Remove tseslint.configs.recommended and replace with this
tseslint.configs.recommendedTypeChecked,
// Alternatively, use this for stricter rules
tseslint.configs.strictTypeChecked,
// Optionally, add this for stylistic rules
tseslint.configs.stylisticTypeChecked,
// Other configs...
],
languageOptions: {
parserOptions: {
project: ['./tsconfig.node.json', './tsconfig.app.json'],
tsconfigRootDir: import.meta.dirname,
},
// other options...
},
},
])
You can also install eslint-plugin-react-x and eslint-plugin-react-dom for React-specific lint rules:
// eslint.config.js
import reactX from 'eslint-plugin-react-x'
import reactDom from 'eslint-plugin-react-dom'
export default defineConfig([
globalIgnores(['dist']),
{
files: ['**/*.{ts,tsx}'],
extends: [
// Other configs...
// Enable lint rules for React
reactX.configs['recommended-typescript'],
// Enable lint rules for React DOM
reactDom.configs.recommended,
],
languageOptions: {
parserOptions: {
project: ['./tsconfig.node.json', './tsconfig.app.json'],
tsconfigRootDir: import.meta.dirname,
},
// other options...
},
},
])
