SSR breaks the library on Nuxt 3 (`document is not defined`)

[mateo-m]

Describe the bug We are trying to use this plugin in an SSR web app built with Nuxt 3 and deployed to Cloudflare Pages. This library seems to rely on a dependency called ScriptJS which relies on document, which isn't defined when the page is served to the end user.

Here's the line that seems to break the library: https://github.com/capacitor-community/apple-sign-in/blob/6c86981ae26e33416bf7bd7bd5a3eb3983231bdb/src/web.ts#L2

Here's the full log of the error:

To Reproduce Steps to reproduce the behavior:

1. Create a Nuxt 3 project.
2. Install the library.
3. Run the following script to build the project and run a local Wrangler server: "localwrangler": "NITRO_PRESET=cloudflare-pages npx nuxi build && npx wrangler pages dev dist/" (more information here: https://developers.cloudflare.com/workers/wrangler/commands/#dev).
4. See the error I mentioned on the bug description.

Expected behavior If the library is used in a web app, it shouldn't have to forcibly rely on document as some apps might not be served as SPAs or rendered on the client-side.

Desktop (please complete the following information): This doesn't really matter because the web app simply doesn't run, but I'll fill it as the template asks for this information.

• OS: macOS
• Browser: Brave
• Version: Version 1.52.126 Chromium: 114.0.5735.133 (Official Build) (arm64)

Additional context We made a quick hotfix consisting in a Nuxt plugin forcing this library to be loaded/rendered on the client-side, which always has a defined document.

Here's the code for it:

1. Create a client-side plugin:

   
   import { SignInWithApple } from '@capacitor-community/apple-sign-in';

export default defineNuxtPlugin(() => { return { provide: { SignInWithApple, }, }; });

2. Add the plugin inside the component you want to use it in:

const { $SignInWithApple } = useNuxtApp();

3. Use the plugin inside the sign in method:

const signInApple = async () => { try { const { response } = await ($SignInWithApple as any).authorize({ clientId: import.meta.env.VITE_APPLE_CLIENT_ID, redirectURI: import.meta.env.VITE_API_URL, });

const data = await loginApi.signInApple({
  token: response.identityToken,
});

} catch (error) { console.log(error); } };
