Vite
Vite config loads an ESM-only package with require
Failed to resolve "foo". This package is ESM only but it was tried to load by `require`.
Vite hit an ESM-only package from a CommonJS-style config path, so Node could not load the dependency with require.
Observed message
Failed to resolve "foo". This package is ESM only but it was tried to load by `require`.
Why it happens
- A Vite config or dependency path uses require to load an ESM-only package.
- The Vite config file is still treated as CommonJS.
- The surrounding package configuration does not opt the project into ESM.
How to fix it
- Convert the Vite config to ESM-compatible imports.
- Add "type": "module" to the nearest package.json when appropriate.
- Rename vite.config.js or vite.config.ts to vite.config.mjs or vite.config.mts if that better fits the project setup.
