How do I fix the error I'm getting trying to include a package? |
Most of these issues come from Vite trying to deal with non-ESM libraries. You may find helpful examples in the Vite issue tracker. The most common solutions would be to try moving the package between dependencies and devDependencies or trying to include or exclude it in optimizeDeps. Packages which use exports instead of module.exports are currently failing due to a known Vite issue. You should also consider asking the library author to distribute an ESM version of their package or even converting the source for the package entirely to ESM.
You should also add any Svelte components to ssr.noExternal. We hope to do this automatically in the future by detecting the svelte field in a package's package.json.
