🚨 Fix "global is not defined" Error in Angular 15+ – Step-by-Step Guide
🚨 **Fix "global is not defined" Error in Angular 15+ – Step-by-Step Guide**
In this tutorial, I’ll show you how to fix the **"Uncaught ReferenceError: global is not defined"** issue that may arise in Angular 15+ projects, especially when working with libraries that expect Node.js-like environments (e.g., WebSockets, STOMP.js). Follow these steps to add the necessary polyfills and configure your Angular project for seamless execution.
### Steps:
1. **Install the required polyfill packages**:
To provide polyfills for `global` and `process` in a browser environment, install the `global` and `process` packages.
```bash
npm install global process --save
```
2. **Update `package.json`**:
Add the following entry in your `package.json` file to include the polyfills in the browser environment.
```json
"browser": {
"global": "global",
"process": "process/browser"
}
```
3. **Update `angular.json`**:
In the `angular.json` file, add the polyfills reference in the `polyfills` section to ensure they are included in the build process.
```json
"polyfills": [
"zone.js",
"src/polyfills.ts"
]
```
4. **Create or update `polyfills.ts`**:
In your `src` directory, create a `polyfills.ts` file with the following content to define `global`:
```typescript
// src/polyfills.ts
(window as any).global = window;
```
5. **Ensure `polyfills.ts` is included in `tsconfig.app.json`**:
Lastly, update your `tsconfig.app.json` to include `polyfills.ts` in the `files` array.
```json
"files": [
"src/main.ts",
"src/polyfills.ts"
]
```
After these steps, your Angular 15+ project will recognize `global` and `process`, resolving the error and allowing your app to run smoothly.
