Securing an Angular 6 / 7 app by hiding/obfuscating the code

If you have Angular 7+, you can make use @angular-builders/custom-webpack to utilize javascript-obfuscator. Note that I linked the custom-webpack for Angular 8+, assuming that you may have upgraded since a year ago. If you need an Angular 7 version, they have a link on that page to the Angular 7 compatible version of @angular-builders/custom-webpack

When you use Angular CLI to build production code, your code is already minified and uglified (by UglifyJS) as said in the Angular doc

The --prod meta-flag engages the following build optimization features. - Ahead-of-Time (AOT) Compilation: pre-compiles Angular component templates. - Production mode: deploys the production environment which enables production mode. - Bundling: concatenates your many application and library files into a few bundles. - Minification: removes excess whitespace, comments, and optional tokens. - Uglification: rewrites code to use short, cryptic variable and function names. - Dead code elimination: removes unreferenced modules and much unused code.

If you didn't get code objuscation, you may need to check your angular.json file and make sure it contains the following settings:

"configurations": {  "production": {    "optimization": true,
