# Maintainers Wanted

This project was originally intended to be only consumed by my NG applications. 
I'm now working full-time on React related project only and it's been a while since I did look into Angular related code.

However, since there are now several people relying on this small and simple package, I'm looking for volunteers to actiely look after this project.
If anyone is interested, please reply into [this ticket](https://github.com/andreasonny83/angular2-cookie-law/issues/63).

## Installation

1.  Install the component using `npm`
1.  angular2-cookie-law depends on the Angular animations module in order to be able to do more advanced transitions. If you want these animations to work in your app, you have to install the `@angular/animations` module and include the `BrowserAnimationsModule` in your app.

```bash
  # To get the latest stable version and update package.json file:
  $ npm install angular2-cookie-law@6 @angular/animations --save
  ```

or `yarn` with:

```bash
  $ yarn add angular2-cookie-law @angular/animations
  ```

## Setup

angular2-cookie-law class is an Angular module therefore,
it needs to be registered in the modules array (encouraged way):

```js
// app.module.ts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { CookieLawModule } from 'angular2-cookie-law';
import { AppComponent } from './app.component';

@NgModule({
  declarations: [ AppComponent ],
  imports: [
    BrowserModule,
    BrowserAnimationsModule, // BrowserAnimationsModule is required
    CookieLawModule // import Angular's CookieLaw modules
  ],
  bootstrap: [ AppComponent ]
})
export class AppModule { }
```

## Usage

Use the component anywhere around your application:

```js
// app.component.ts
import { Component } from '@angular/core';

@Component({
  selector: 'app',
  template: `
    <cookie-law></cookie-law>
  `
})
export class AppComponent  { }
```

## Example

```js
// app.component.ts
import { Component } from '@angular/core';

@Component({
  selector: 'app',
  template: `
    <h1>
      Hello World!
    </h1>

<cookie-law></cookie-law>
  `
})
export class AppComponent  { }
```
