# @push.rocks/webdetector
detect different environments within the browser

## Install
To install `@push.rocks/webdetector`, you can use npm or yarn. Run the following command in your terminal:

```bash
npm install @push.rocks/webdetector --save
```
or if you prefer using yarn:
```bash
yarn add @push.rocks/webdetector
```

This package is designed to work in a browser environment.

## Usage
The `@push.rocks/webdetector` module provides a powerful toolset to detect various aspects of the user's browser environment, such as online status, platform type, and PWA (Progressive Web App) installation status. It leverages modern web technologies and observables for real-time detection and updates.

### Importing the Module
First, you need to import the module in your project using ESM syntax:

```typescript
import { WebDetector } from '@push.rocks/webdetector';
```

### Initializing WebDetector
To start utilizing WebDetector, you need to create an instance of it by passing configuration options. The most crucial option is the `checkOnlineUrl`, which is used to verify internet connectivity.

```typescript
const webDetector = new WebDetector({
  checkOnlineUrl: 'https://example.com', // URL to check online status
});
```

### Checking Online Status
WebDetector can check if the browser can reach the internet. This is not a mere online/offline status provided by the browser but a more reliable check that attempts to fetch a predetermined URL.

```typescript
async function checkOnlineStatus() {
  const isOnline = await webDetector.isOnline();
  console.log(`Online status: ${isOnline}`);
}
checkOnlineStatus();
```

### Observing Real-Time Online Status
WebDetector allows you to observe changes in online status in real-time, which is useful for applications that need to react to connectivity changes promptly.

```typescript
webDetector.startPeriodicChecks();
webDetector.onlineObservable.subscribe((state) => {
  console.log(`Current state: ${state}`);
});

// Remember to stop the periodic checks when they are no longer needed
webDetector.stopPeriodicChecks();
```

### Detecting the Platform
You can easily detect the user's platform (e.g., iOS, Android, Windows, etc.) using WebDetector.

```typescript
const platform = webDetector.platform.detectPlatform();
console.log(`Platform detected: ${platform}`);
```

### Checking PWA Installation Status
For Progressive Web Apps, it's vital to know if the user has installed the app. WebDetector provides a straightforward way to check this.

```typescript
const isPwaInstalled = webDetector.pwa.isInstalled();
console.log(`Is PWA Installed: ${isPwaInstalled}`);
```

### Comprehensive Observables Integration
`@push.rocks/webdetector` integrates seamlessly with observables provided by RxJS through `@pushrocks/smartrx`, making it easy to integrate with frameworks that use observables for state management.

### Conclusion
`@push.rocks/webdetector` is a versatile module that helps detect various aspects of the browser environment, offering tools for checking connectivity, platform type, and PWA installation status. By utilizing observables for real-time updates, it fits well into modern web application architectures.

Remember, the accurate detection and reaction to the user's environment enhance the user experience significantly, making `@push.rocks/webdetector` a valuable addition to your web development toolkit.
