Current behavior

ServeStaticModule.forRoot({
      rootPath: join(__dirname, '..', '.well-known/apple-app-site-association'),
      serveStaticOptions: { index: ['index.json'] },
}),

The code above does still not work if index.html is not available.

Expected behavior

I want to serve the JSON file instead of HTML.

What is the motivation / use case for changing the behavior?

I need apple app site association file for the deep-linking iOS app with my backend.

Environment

Nest version: 6.11.11

 
For Tooling issues:
- Node version: 10.12.18  
- Platform: Linux

You shouldn't use serve-static module for this. This package is intended to minimize & simplify the boilerplate code needed for serving SPA from Nest.

Instead, you should rather look at the useStaticAssets() method which gives more control & flexibility. You can find some usage examples here https://docs.nestjs.com/techniques/mvc
