BYTEHIDE SHIELD FOR ANGULAR
Angular Obfuscator
Protect your Angular application against reverse engineering, copying, and tampering. ByteHide Shield integrates with the Angular build to obfuscate your compiled output.
Get started
Angular
npm install @bytehide/angular-shield --save-dev
// After ng build, add to package.json scripts:
"build:prod": "ng build && angular-shield --token YOUR_TOKEN"Add the Shield package as a post-build step. After Angular's production build, Shield protects the bundle output automatically.
Full setup guide in the docsFree to use with a ByteHide account
The first time Shield runs, it asks for a project token that connects it to your account. The package is free.

How to obfuscate an Angular application
Angular compiles to a JavaScript bundle for the browser. Shield protects that output. Three steps.
Step 01
Install the Angular plugin
Add @bytehide/angular-shield as a dev dependency.
Step 02
Add a post-build step
Add the Shield obfuscation step after ng build, with your project token.
Step 03
Build for production
Run ng build for production. Shield protects the bundle output automatically.
Why obfuscate
Why obfuscate Angular code
Angular compiles your application into JavaScript bundles for the browser. Your components, services, and logic ship in that output, readable.
- Your services hold the logic worth protectingAngular services centralize business logic, authentication, and API calls. In the compiled bundle, that logic is readable without obfuscation.
- Enterprise Angular apps are high-value targetsAngular is common in enterprise applications, where the frontend often carries significant proprietary logic. That makes obfuscation more important, not less.
- A readable bundle exposes your architectureWithout obfuscation, your Angular app's structure and logic can be studied and replicated.
Example
See Angular obfuscation in action
Obfuscation is easier to understand when you see it. Here is a small Angular service before and after Shield protects the compiled output.
import { Injectable } from '@angular/core';
@Injectable({ providedIn: 'root' })
export class AuthService {
private apiKey = 'ByteH1de!2026';
isAuthenticated(token: string): boolean {
return token === this.apiKey;
}
}var _0xb3=['f4a1','8c2e','d71f'];function _0x2a(t){var _s=0;while(1)switch(_s){
case 0: _0xb3[1]=_dec(0x1a); _s=1; break;
case 1: return t===_0xb3[0];
}}var _0x5f=function(){this._0x9c=_dec(0x2b);};
_0x5f.prototype._0x7d=function(_0xe){return _0x2a(_0xe);};
module.exports=_0x5f;Same behavior, unreadable result. The compiled bundle reveals nothing about your services or business logic.
What it covers
What ByteHide Shield protects in your Angular build
Shield applies its protection to the JavaScript bundles Angular produces. Here is what that covers.
- Your service logicThe functions, classes, and algorithms in your Angular services become unreadable in the shipped bundle. The behavior is identical, the logic is not legible.
- Your strings and endpointsAPI endpoints, keys, messages, and configuration values are encrypted, so they cannot be read by scanning the compiled bundle.
- Your control flowThe structure of your logic is reshaped so the program flow cannot be followed, even after the bundle is beautified.
- Your bundle, every buildProtection runs as part of your build pipeline, so every release ships obfuscated automatically. There is no manual step to forget.
Your services carry the most value. Shield protects them in the build that ships.
Build
Angular obfuscation: what to protect and what to exclude
Angular's build produces several kinds of files. Some carry your application logic and should be protected. Others should stay untouched.
- Angular CLI generates bundles in distng build outputs main, polyfills, runtime, and chunk files in the dist folder. Shield protects the bundles that carry your application logic.
- Shield excludes the files that should stay untouchedThe Angular plugin automatically excludes files like polyfills, runtime, and vendor, which should not be obfuscated for compatibility.
- Production builds, not developmentObfuscation is applied to production builds. Development builds stay readable for debugging.
Protect what carries your logic. Leave the platform files alone.
Free tool vs Shield
Free obfuscator vs ByteHide Shield
For a quick test of a single JavaScript file, the free online obfuscator is enough. For a real Angular application, ByteHide Shield protects the whole build.
ByteHide Shield
Production-grade protection
The free online tool obfuscates single JavaScript files. ByteHide Shield protects a full Angular application, built into your pipeline.
