Angular Setup

Create a target in your angular.json file. Like the one shown bellow. Other targets like lint or build are located in the same place.

Important make sure your levels of obfuscation and performance is suitable for your project! The default parameters are most likely not what you want.

{
  "obfuscate": {
    "builder": "@rcarver/ngx-source-obfuscation:obfuscate",
    "options": {
      "files": [
        {
          "glob": "main*.js",
          "input": "www",
          "output": "www"
        }
      ],
      "sourceMap": true,
      "sourceMapMode": "separate"
    },
    "configurations": {
      "production": {
        "debugProtection": true,
        "debugProtectionInterval": true,
        "sourceMap": false
      }
    }
  }
}

Files are obfuscated in-place (existing files are modified). A Live Demo of the obfuscation library https://obfuscator.io/ is provided by the author of the library. A list of available configuration options can be found here
