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.

Example:

{
  "obfuscate": {
    "builder": "@russcarver/ngx-source-obfuscation:obfuscate",
    "options": {
      "files": [
        {
          "fileExtensions": ["js"],
          "filePatternsToExclude": ["polyfills"],
          "input": "dist",
          "output": "."
        }
      ]
    },
    "configurations": {
      "production": {
        "debugProtection": true,
        "debugProtectionInterval": true,
        "sourceMap": false
      }
    }
  }
}

Files options

1. fileExtensions (required). This is an array of strings representing exact, case-insensitive file extensions of files you want to obfuscate.
2. filePatternsToExclude (optional). This is an array of case-insensitive strings representing strings, that if found anywhere in the filename or extension (or combined aka: a full name.ext), will be excluded from obfuscation.
3. input (required). This is the relative input path in which to search for files. It will search 30 nested directories deep from this path.
4. output (required). This is the relative output path from the input path in which to place the obfuscated results.

If the output path refers to the same directory as the input path, then 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

Running the task
