Thank you for the PR.
We should structure the exports a bit different:
- don't export the UMD module
- use the es-version for browser only
- use the minified files
"exports": {
"node": "./dist/jspdf.node.min.js"
"browser": "./dist/jspdf.es.min.js"
"types": "./types/index.d.ts"
}
Ideally, we would have a modules build for node, as well, but we can do that later, too.
Move the vite test app to the examples folder and don't commit the dist files.
- Update exports field to use node/browser format with minified files - Remove UMD module from exports as requested - Move test-vite to examples/vite folder - Remove committed dist files from git - Update package.json path reference in example Changes requested by @HackbrettXXX in PR review

- Remove VITE_COMPATIBILITY_FIX.md as suggested - Format example files with Prettier to pass lint checks

@HackbrettXXX It's not a standard GitHub pattern - I had created it as documentation to explain the fix, but you're right that it's not necessary. I've removed it now along with fixing the linting issues. The PR should be clean now! |
