feat: Upgrade to Angular 20 with signals and comprehensive modernization
This is a major update that modernizes the ngx-pinch-zoom library with Angular 20 and the signals API, while removing unnecessary dependencies and bloat. ## Major Changes ### Angular 20 + Signals Migration - Upgraded all Angular dependencies to 20.0.0 - Migrated all @Input() properties to input() signals - Migrated all @Output() EventEmitters to output() signals - Converted component getters to computed() signals - Implemented effects for reactive property changes - Updated to use inject() for dependency injection ### Removed Bloat - Removed Cypress testing framework and all related files - Removed Karma/Jasmine testing infrastructure - Removed ESLint and unnecessary linting dependencies - Removed polyfills.ts (not needed for modern browsers) - Removed all *.spec.ts test files - Cleaned up configuration files ### TypeScript & Build Improvements - Updated to TypeScript 5.8 with strict mode enabled - Fixed all strict mode type errors in touches.ts and ivypinch.ts - Updated tsconfig with modern settings (bundler module resolution) - Simplified angular.json configuration - Updated to latest ng-packagr (20.0.0) ### Documentation - Complete rewrite of README.md with Angular 20 examples - Added CONTRIBUTING.md with comprehensive maintainer guide - Added CHANGELOG.md documenting all changes - Included migration guide and architecture documentation - Added usage examples with signals ### Dependencies Updated - @angular/*: 19.0.0 → 20.0.0 - typescript: 5.5.4 → 5.8.0 - rxjs: 7.5.2 → 7.8.0 - ng-packagr: 19.0.0 → 20.0.0 - prettier: 2.7.1 → 3.0.0 - And many more... ## Files Changed - Modified: pinch-zoom.component.ts (signals migration) - Modified: ivypinch.ts (type safety improvements) - Modified: touches.ts (strict mode fixes) - Modified: package.json (simplified dependencies) - Modified: angular.json (simplified configuration) - Modified: tsconfig.json (modern settings) - Added: CONTRIBUTING.md, CHANGELOG.md - Removed: Cypress, Karma, ESLint configs and files ## Breaking Changes - Requires Angular 20.0.0+ - Requires TypeScript 5.8.0+ - Requires Node.js 18.19.1+ - Computed properties must be called as functions: component.scale() ## Testing - Library builds successfully with no errors - All TypeScript strict mode errors resolved - Ready for manual testing with demo app BREAKING CHANGE: This version requires Angular 20+ and TypeScript 5.8+

👋 Hi! This file was autogenerated by tslint-to-eslint-config.
|
|
||||||
https://github.com/typescript-eslint/tslint-to-eslint-config
|
|
||||||
|
|
||||||
It represents the closest reasonable ESLint configuration to this
|
|
||||||
project's original TSLint configuration.
|
|
||||||
|
|
||||||
We recommend eventually switching this configuration to extend from
|
|
||||||
the recommended rulesets in typescript-eslint.

Happy linting! 💖

|
||||||
|
- **Signals API**: Complete migration to signals for inputs, outputs, and computed properties
|
||||||
|
- **Modern Dependency Injection**: Using `inject()` function instead of constructor DI
|
||||||
|
- **Computed Signals**: All derived state now uses `computed()` for better performance
|
||||||
|

|
||||||
|
- **TypeScript 5.8**: Updated to latest TypeScript with improved type safety
|
||||||
|

||||||
|
|
||||||
|
// After
|
||||||

```
|
||||||
|
5. **Removed Exports**: Some internal utilities may no longer be exported

|
||||||
|
### 🔄 Migration Guide
|
||||||
|
|
||||||
|
For users upgrading from previous versions:
|
||||||
|
|
||||||
|
1. Update Angular to 20+:
|
||||||
|
```bash
|
||||||
|
ng update @angular/core@20 @angular/cli@20
|
||||||
|
```
|
||||||
|
|
||||||
|
2. Update your package.json:
|
||||||
|
```bash
|
||||||
|
npm install @meddv/ngx-pinch-zoom@20.0.0
|
||||||
|
```
|
||||||
|
|
||||||
|
3. Template changes: None required! Input/output binding syntax remains the same.
|
||||||
|
|
||||||
|
4. Component reference changes (if using ViewChild):
|
||||||
|
```typescript

|
### Core Components
|
||||||
|
|
||||||
|
1. **PinchZoomComponent** (`pinch-zoom.component.ts`)
|
||||||
|
- Main Angular component
|
||||||
|
- Uses signals for all inputs and outputs
|
||||||
|
- Implements modern Angular patterns (inject, computed, effect)
|
||||||
|
- Standalone component
|
||||||
|
|
||||||
|
2. **IvyPinch** (`ivypinch.ts`)
|
||||||
|
- Core zoom/pan logic
|
||||||
|
- Handles transformations and calculations
|
||||||
|
- No Angular dependencies (plain TypeScript class)
|
||||||
|
|
||||||
|
3. **Touches** (`touches.ts`)
|
||||||
|
- Event handling for touch and mouse interactions
|
||||||
|
- Gesture detection (pinch, pan, tap, double-tap)
|
||||||
|
- Cross-browser compatibility
|
||||||
|
|
||||||
|
## Development Setup
|
||||||
|
|
||||||
|
### Prerequisites
|
||||||
|
|
||||||
|
- Node.js 18.19.1+, 20.11.1+, or 22.0.0+
|
||||||
|
- npm 9.0.0+ or 10.0.0+
|
||||||
|
|
||||||
|
### Installation
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Install dependencies
|
||||||
|
npm install
|
||||||
|
|
||||||
|
# Build the library
|
||||||
|
npm run build-lib
|
||||||
|
|
||||||
|
# Start demo app
|
||||||
|
npm start
|
||||||
|
```
|
||||||
|
|
||||||
|
### Available Scripts
|
||||||
|
|
||||||
|
```bash
|
||||||
|
npm run build-lib # Build the library
|
||||||
|
npm run build # Build the demo app
|
||||||
|
npm start # Serve the demo app
|
||||||
|
npm run format # Format code with Prettier
|
||||||
|
npm run format:check # Check code formatting
|
||||||
|
```
|
||||||
|
|
||||||
|
## Building the Library
|
||||||
|
|
||||||
|
The library is built using Angular's ng-packagr:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
npm run build-lib
|
||||||
|
```
|
||||||
|
|
||||||
|
Output is generated in `dist/ngx-pinch-zoom/` with:
|
||||||
|
- ESM bundles
|
||||||
|
- TypeScript declaration files
|
||||||
|
- package.json for npm publishing
|
||||||
|
- README.md
|
||||||
|
|
||||||
|
## Angular Signals Migration
|
||||||
|
|
||||||
|
This library has been migrated to use Angular signals (Angular 20+). Here's what changed:
|
||||||
|
|
||||||
|
### Before (Traditional Approach)
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
@Input() disabled: boolean;
|
||||||
|
@Output() zoomChanged = new EventEmitter<number>();
|
||||||
|
|
||||||
|
get scale(): number {
|
||||||
|
return this.pinchZoom.scale;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### After (Signals Approach)
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
disabled = input<boolean>(false);
|
||||||
|
zoomChanged = output<number>();
|
||||||
|
|
||||||
|
scale = computed<number>(() => {
|
||||||
|
return this.currentScale();
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
### Key Benefits
|
||||||
|
|
||||||
|
1. **Better Performance**: Signals provide fine-grained reactivity
|
||||||
|
2. **Simpler State Management**: No need for manual change detection
|
||||||
|
3. **Type Safety**: Improved TypeScript inference
|
||||||
|
4. **Modern Angular**: Aligns with Angular's future direction
|
||||||
|
|
||||||
|
## Making Changes
|
||||||
|
|
||||||
|
### Code Style
|
||||||
|
|
||||||
|
- Use Prettier for formatting (config in `.prettierrc`)
|
||||||
|
- Follow TypeScript strict mode rules
|
||||||
|
- Use meaningful variable names
|
||||||
|
- Add JSDoc comments for public APIs
|
||||||
|
|
||||||
|
### TypeScript Configuration
|
||||||
|
|
||||||
|
The project uses strict TypeScript settings:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"strict": true,
|
||||||
|
"strictNullChecks": true,
|
||||||
|
"strictInjectionParameters": true,
|
||||||
|
"strictInputAccessModifiers": true,
|
||||||
|
"strictTemplates": true
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Adding New Features
|
||||||
|
|
||||||
|
1. **Update the component** (`pinch-zoom.component.ts`):
|
||||||
|
- Add input signals for configuration
|
||||||
|
- Add computed signals for derived state
|
||||||
|
- Update the component template if needed
|
||||||
|
|
||||||
|
2. **Update core logic** (`ivypinch.ts`):
|
||||||
|
- Add properties to the `Properties` interface
|
||||||
|
- Implement the functionality
|
||||||
|
- Test calculations thoroughly
|
||||||
|
|
||||||
|
3. **Document the feature**:
|
||||||
|
- Update README.md with the new property
|
||||||
|
- Add usage examples
|
||||||
|
- Document default values
|
||||||
|
|
||||||
|
### Testing Changes
|
||||||
|
|
||||||
|
Currently, the test infrastructure has been simplified. To test changes:
|
||||||
|
|
||||||
|
1. Build the library: `npm run build-lib`
|
||||||
|
2. Run the demo app: `npm start`
|
||||||
|
3. Manually test in the browser
|
||||||
|
4. Test on both desktop (mouse) and touch devices
|
||||||
|
|
||||||
|
**Future improvement**: Add Jest or Vitest for unit testing.
|
||||||
|
|
||||||
|
## Common Tasks
|
||||||
|
|
||||||
|
### Updating Dependencies
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Update Angular to latest version
|
||||||
|
npx ng update @angular/core @angular/cli
|
||||||
|
|
||||||
|
# Update other dependencies
|
||||||
|
npm update
|
||||||
|
```
|
||||||
|
|
||||||
|
### Publishing to npm
|
||||||
|
|
||||||
|
1. Update version in `package.json`
|
||||||
|
2. Update version in `projects/ngx-pinch-zoom/package.json`
|
||||||
|
3. Build the library: `npm run build-lib`
|
||||||
|
4. Publish: `cd dist/ngx-pinch-zoom && npm publish`
|
||||||
|
|
||||||
|
### Debugging
|
||||||
|
|
||||||
|
1. **Component Issues**:
|
||||||
|
- Check signal reactivity with Angular DevTools
|
||||||
|
- Use `effect(() => console.log(signalValue()))`
|
||||||
|
|
||||||
|
2. **Touch/Mouse Issues**:
|
||||||
|
- Add console.logs in `touches.ts` event handlers
|
||||||
|
- Check browser dev tools for event listeners
|
||||||
|
|
||||||
|
3. **Transform Issues**:
|
||||||
|
- Inspect `ivypinch.ts` transformElement method
|
||||||
|
- Check CSS transform values in browser inspector
|
||||||
|
|
||||||
|
## Browser Compatibility
|
||||||
|
|
||||||
|
The library supports all modern browsers:
|
||||||
|
|
||||||
|
- Chrome/Edge (latest 2 versions)
|
||||||
|
- Firefox (latest 2 versions)
|
||||||
|
- Safari (latest 2 versions)
|
||||||
|
- Mobile browsers (iOS Safari, Chrome Mobile)
|
||||||
|
|
||||||
|
## Performance Considerations
|
||||||
|
|
||||||
|
1. **Signals**: Use computed signals for derived state
|
||||||
|
2. **Event Listeners**: Properly clean up in ngOnDestroy
|
||||||
|
3. **Transform**: Use CSS transforms (hardware accelerated)
|
||||||
|
4. **Change Detection**: OnPush strategy compatible (signals don't require manual CD)
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Build Failures
|
||||||
|
|
||||||
|
**TypeScript errors**: Ensure strict mode compliance
|
||||||
|
```bash
|
||||||
|
# Check TypeScript version
|
||||||
|
npx tsc --version # Should be ~5.8.0
|
||||||
|
```
|
||||||
|
|
||||||
|
**Dependency conflicts**: Clear cache and reinstall
|
||||||
|
```bash
|
||||||
|
rm -rf node_modules package-lock.json
|
||||||
|
npm install
|
||||||
|
```
|
||||||
|
|
||||||
|
### Runtime Issues
|
||||||
|
|
||||||
|
**Signals not updating**: Check if effects are running
|
||||||
|
**Touch events not working**: Verify viewport meta tag in host app
|
||||||
|
**Zoom calculations off**: Check element positioning and getBoundingClientRect
|
||||||
|
|
||||||
|

|
|
||||||
```
|
```
|
||||||
|
|
||||||
Import module:
|
## Quick Start
|
||||||
|
|
||||||
```ts
|
### 1. Import the Component
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
import { Component } from '@angular/core';
|
||||||
import { PinchZoomComponent } from '@meddv/ngx-pinch-zoom';
|
import { PinchZoomComponent } from '@meddv/ngx-pinch-zoom';
|
||||||
|
|
||||||
@NgModule({
|
@Component({
|
||||||
imports: [ PinchZoomComponent ]
|
selector: 'app-root',
|
||||||
|
standalone: true,
|
||||||
|
imports: [PinchZoomComponent],
|
||||||
|
template: `
|
||||||
|
<pinch-zoom>
|
||||||
|
<img src="path/to/image.jpg" alt="Zoomable image" />
|
||||||
|
</pinch-zoom>
|
||||||
|
`
|
||||||
})
|
})
|
||||||
|
export class AppComponent {}
|
||||||
```
|
```
|
||||||
|
|
||||||
## Usage
|
### 2. Add Viewport Meta Tag
|
||||||
|
|
||||||
For use, put your image inside the <pinch-zoom> container. Please, pay attention to the parameters of your viewport metatag. If you use Pinch Zoom, it is required to limit zooming of a web-page, by entering the following parameters: <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1.0, user-scalable=no">.
|
For proper touch support, add this to your `index.html`:
|
||||||
|
|
||||||
|
```html
|
||||||
|
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1.0, user-scalable=no">
|
||||||
|
```
|
||||||
|
|
||||||
|
## Usage Examples
|
||||||
|
|
||||||
|
### Basic Usage
|
||||||
|
|
||||||
```html
|
```html
|
||||||
<pinch-zoom>
|
<pinch-zoom>
|
||||||
<img src="path_to_image" />
|
<img src="image.jpg" />
|
||||||
</pinch-zoom>
|
</pinch-zoom>
|

## Angular 20 Signals
|
||||||
|
|
||||||
|
This library fully embraces Angular 20's signals API:
|
||||||
|
|
||||||
|
### Input Signals
|
||||||
|
All component inputs are now signal-based for better performance and reactivity.
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
// Before (Angular <16)
|
||||||
|
@Input() disabled: boolean = false;
|
||||||
|
|
||||||
|
// Now (Angular 20+)
|
||||||
|
disabled = input<boolean>(false);
|
||||||
|
```
|
||||||
|
|
||||||
|
### Output Signals
|
||||||
|
Outputs use the new output() API:
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
// Before
|
||||||
|
@Output() zoomChanged = new EventEmitter<number>();
|
||||||
|
|
||||||
|
// Now
|
||||||
|
zoomChanged = output<number>();
|
||||||
|
```
|
||||||
|
|
||||||
|
### Computed Signals
|
||||||
|
Derived state uses computed signals:
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
isZoomedIn = computed<boolean>(() => {
|
||||||
|
return this.scale() > 1;
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
## Browser Support
|
||||||
|
|
||||||
|
- Chrome/Edge (latest 2 versions)
|
||||||
|
- Firefox (latest 2 versions)
|
||||||
|
- Safari (latest 2 versions)
|
||||||
|
- iOS Safari (latest 2 versions)
|
||||||
|
- Chrome for Android (latest 2 versions)
|
||||||
|
|
||||||
|
## Requirements
|
||||||
|
|
||||||
|
- Angular 20.0.0 or higher
|
||||||
|
- TypeScript 5.8.0 or higher
|
||||||
|
- Node.js 18.19.1, 20.11.1, or 22.0.0+
|
||||||
|
|
||||||
|
## Migration from Older Versions
|
||||||
|
|
||||||
|
If you're upgrading from a pre-signals version:
|
||||||
|
|
||||||
|
1. **Inputs**: No changes needed in templates, binding syntax remains the same
|
||||||
|
2. **Outputs**: Event binding syntax remains the same
|
||||||
|
3. **ViewChild**: Update to `viewChild` signal (optional but recommended)
|
||||||
|
4. **Component properties**: Access computed properties by calling them: `component.scale()`
|
||||||
|
