    "body": "## Symptom\nAfter upgrading to Vite 7, loading the config fails:\n\n```\nfailed to load config from .../electron.vite.config.ts\nSyntaxError: The requested module 'vite' does not provide an export named 'splitVendorChunk'\n```\n(or `... named 'splitVendorChunkPlugin'`). It comes either from your own `vite.config` (`import { splitVendorChunkPlugin } from 'vite'`) or from a wrapper that re-exports it, e.g. electron-vite 3.x `dist/index.mjs`.\n\n## Cause\n`splitVendorChunkPlugin` was deprecated in Vite 5.2.7 and removed in Vite 7.0 (released 2025-06-24) along with other deprecated features. Wrappers built for Vite 5/6 still import it.\n\n## Fix\nIf your config uses it, delete the plugin and chunk manually.\n\nBefore:\n```js\nimport { defineConfig, splitVendorChunkPlugin } from 'vite'\nexport default defineConfig({ plugins: [splitVendorChunkPlugin()] })\n```\nAfter (Vite 7, Rollup):\n```js\nimport { defineConfig } from 'vite'\nexport default defineConfig({\n  build: { rollupOptions: { output: {\n    manualChunks: (id) => (id.includes('node_modules') ? 'vendor' : undefined),\n  } } },\n})\n```\nAfter (Vite 8, Rolldown; function-form manualChunks is deprecated there):\n```js\nexport default defineConfig({\n  build: { rolldownOptions: { output: {\n    codeSplitting: { groups: [{ test: /node_modules/, name: 'vendor' }] },\n  } } },\n})\n```\nIf a dependency imports it (check the stack-trace path): upgrade that tool to a Vite-7-compatible major (electron-vite v4+ supports Vite 7) or keep Vite at the version the tool supports; remove any `overrides`/`resolutions` that force a newer Vite. `npm ls vite` shows who pulls which version.\n\n## Verify\n`vite build` loads the config and emits a separate vendor chunk in `dist/assets`.\n\n## Sources\n- https://v7.vite.dev/guide/migration\n- https://vite.dev/blog/announcing-vite7\n- https://github.com/alex8088/electron-vite/issues/795\n- https://vite.dev/guide/migration\n- https://rolldown.rs/in-depth/manual-code-splitting",
