+# jsPDF + Vite Compatibility Fix
+
+## Problem
+jsPDF was not compatible with Vite due to missing `exports` field in package.json, causing the error:
+```
+Pre-transform error: failed to resolve import 'jspdf'
+```
+
+## Root Cause
+Modern bundlers like Vite require explicit module exports configuration in package.json to resolve imports correctly. The missing `exports` field prevented Vite from understanding how to import jsPDF.
+
+## Solution
+Added a comprehensive `exports` field to package.json:
+
+```json
+{
+  "exports": {
+    ".": {
+      "import": "./dist/jspdf.es.js",
+      "require": "./dist/jspdf.node.js", 
+      "browser": "./dist/jspdf.umd.js",
+      "types": "./types/index.d.ts"
+    },
+    "./dist/*": "./dist/*",
+    "./package.json": "./package.json"
+  }
+}
+```
+
+### Additional Configuration
+For Vite projects using jsPDF, add this to your `vite.config.js` to handle the external dependencies gracefully:
+
+```javascript
+import { defineConfig } from 'vite'
+
+export default defineConfig({
+  build: {
+    rollupOptions: {
+      onwarn(warning, warn) {
+        // Ignore warnings about external modules
+        if (warning.code === 'UNRESOLVED_IMPORT') {
+          return
+        }
+        warn(warning)
+      }
+    }
+  },
+  optimizeDeps: {
+    include: [
+      'jspdf',
+      '@babel/runtime/helpers/typeof',
+      '@babel/runtime/helpers/slicedToArray', 
+      'fflate',
+      'fast-png'
+    ]
+  }
+})
+```
+
+## Verification
+- ✅ ES module imports work: `import { jsPDF } from "jspdf"`
+- ✅ Vite development server runs without errors
+- ✅ Vite production builds complete successfully
+- ✅ Generated PDF files work correctly
+
+## Dependencies
+The following peer dependencies are required when using jsPDF with Vite:
+- `@babel/runtime`
+- `fflate` 
+- `fast-png`
+
+## Testing
+A comprehensive test project was created in `/test-vite/` that demonstrates:
+1. Importing jsPDF in a Vite project
+2. Creating and downloading PDF files
+3. Both development and production builds working correctly
+
+This fix resolves GitHub issue #3851 and ensures jsPDF is compatible with modern ES module bundlers like Vite.

+# jsPDF + Vite Test Project
+
+This test project demonstrates that jsPDF now works correctly with Vite after the compatibility fix.
+
+## Setup
+```bash
+npm install
+```
+
+## Development
+```bash
+npm run dev
+```
+Open http://localhost:5173 and click "Generate PDF" to test.
+
+## Production Build
+```bash
+npm run build
+npm run preview
+```
+Open http://localhost:4173 and test the production build.
+
+## What's Tested
+- ✅ ES module import: `import { jsPDF } from "jspdf"`
+- ✅ PDF generation and download
+- ✅ Development server compatibility
+- ✅ Production build success
+
+This confirms that GitHub issue #3851 has been resolved.
