Introduction

I have saved .psd, mockups, illustrations, etc. in my monorepo, inside the assets folder. If in the app.json assetBundlePatterns field, I just enter (inside an array) all the relative paths to the images/fonts/audios I use in the frontend, will the rest of useless assets be bundled in the resulting binary?

Example

  • assets folder:
assets/
    fonts/
        GrandHotel.ttf
        OpenSans-Bold.ttf
        OpenSans-Italic.ttf
        OpenSans-Light.ttf
        OpenSans-Regular.ttf
        OpenSans-SemiBold.ttf

   images/
        logo/
            logo.png
            logo.ai
            logo.psd
            icon.png
            icon.psd

        mockups/
            ... images not used in the app ...

   audios/
       new-message.mp3
  • app.json:

"assetBundlePatterns": [
      "./assets/fonts/GrandHotel.ttf",
      "./assets/fonts/OpenSans-Bold.ttf",
      "./assets/fonts/OpenSans-Italic.ttf",
      "./assets/fonts/OpenSans-Light.ttf",
      "./assets/fonts/OpenSans-Regular.ttf",
      "./assets/fonts/OpenSans-SemiBold.ttf",
      "./assets/images/logo/logo.png",
      "./assets/images/logo/icon.png",
      "./assets/audios/new-message.mp3"
]

Another question

Is it possible to simplify the array using patterns? I mean, how can I do, for example, to match all the .png files over the assets/images/logo/ folder? (including possible subdirectories)
