What is "/**/*" for files in package.json for react/electron?

Question

I am trying to create binary for a react electron application and I came across with this in package.json. What does **/* mean ?

   "build": {
    "appId": "com.com.com",
    "productName": "Prost",
    "files": [
      "build/**/*",
      "public/**/*",
      "src/images/**/*"
    ]
  },

Thanks

Answer 1

The ** means any directory - including sub directories.

The * Means any file.

so src/**/* means any file in any directory inside the src directory.

Answer 2

• dir/* - all files in directory,
• dir/*/* - all files in directory and nested directories (1 level deep),
• dir/**/* - all files in directory and all subdirectories.
