TypeError with App router using excalidraw

[engelbrechtz]

I copied the code above, the app router gives me this error, how to solve this issue?

TypeError: _packages_excalidraw_node_modules_css_loader_dist_runtime_api_js__WEBPACK_IMPORTED_MODULE_1___default(...) is not a function

[MinhuaHuang]

me too

const Excalidraw = dynamic(
  async () => (await import("@excalidraw/excalidraw")).Excalidraw,
  {
    ssr: false,
  }
);

next: 14.0.5-canary.68 @excalidraw/excalidraw: 0.17.2

Have you also added use client in the file? can you share a code sandbox reproducible example ?

[damien-schneider]

I can confirm the error, I have the same, even with "use client", and does the same when I don't import it dynamically.

PS : The error appears to me only if I use turbo.

Any news on this? It looks like it doesn't work with turbo, but works with usual Webpack because the library for some reason tries to use css-loader. Here's a call stack:

I use Excalidraw 0.17.3. with Next 14.1.4 and app router.

Additional info: basing on a NextJS sample you've provided I just had to remove line import "@excalidraw/excalidraw/index.css"; because that file doesn't exist in an NPM package.

I get a similar error with @excalidraw/[email protected] and [email protected] but it looks like it's trying to load scss files:

Figured it could be solved by adding .scss support to turbopack (supposed to be supported through Next.js by default) but no dice on that either:

experimental: {
  turbo: {
      rules: {
        '*.scss': {
          loaders: ['style-loader', 'css-loader', 'sass-loader'],
          as: '*.js',
        },
      },
    },
}

Should be fixed with this PR and be part of an upcoming release.
