* Angular 14 (ngx-chat 0.14.x)
* Angular 13 (ngx-chat 0.13.x)

### Installation and usage

These instructions require Angular 12.

First install ngx-chat and its dependencies via npm:

```bash
npm install --save @pazznetwork/ngx-chat @xmpp/client@~0.9.2 @angular/cdk@~14.0.5
```

After that, import ngx-chat in your root module:

```
@NgModule({
    ...
    imports: [
        ...
        NgxChatModule.forRoot(),
        BrowserAnimationsModule, // alternatively NoopAnimationsModule 
    ],
    ...
})
```

Add the `ngx-chat`-component at the end of your root component template:

```html

<ngx-chat></ngx-chat>
``` 

You are now ready to go. You will not see anything until you log in. Log in via `ngx-chat` wherever you want (e.g. in a component or a
service)
by injecting `ChatService` and calling `login`:

```
constructor(@Inject(CHAT_SERVICE_TOKEN) chatService: ChatService) {
    chatService.logIn({
        domain: 'ngx-chat.example',
        service: 'wss://ngx-chat.example:5280/websocket',
        password: 'password',
        username: 'someuser',
    });
}
```

Add the following to polyfills.ts:
```
/***************************************************************************************************
 * APPLICATION IMPORTS
 */
(window as any).global = window;
```

*Optional*: body padding when roster list is expanded

Add css styling like the following to your main styles.css if you want to resize your main content when the roster is expanded.

```css
body {
    transition-property: padding-right;
    transition-duration: 0.4s;
    padding-right: 0;
}

body.has-roster {
    padding-right: 14em;
}
```

### Documentation

Below you will find some instructions to getting
started. [Have a look at the wiki for more FAQ's and abstract documentation.](https://github.com/pazznetwork/ngx-chat/wiki)

For a api, architecture and code overview checkout our [**
compo**doc documentation](https://pazznetwork.github.io/ngx-chat-ghpages/documentation/).

### FAQ

**Q: Which browsers are supported?**  
A: It is tested in Chrome, Safari and Firefox.

**Q: Does ngx-chat work with self-signed certificates?**  
A: Yes, if the following criteria are met:

* the certificate has to be trusted by the browser you are using. Chrome uses the operating system trust store for certificates while
  Firefox has a custom implementation.
* the common name (CN) matches the uri of the service you are connecting to

**Q: Can ngx-chat be used without the UI?**  
A: Yes. Inject the chat service via `@Inject(CHAT_SERVICE_TOKEN) public chatService: ChatService`, login via `logIn` and start sending
messages via the `sendMessage` method.

**Q: My question is not answered**  
A: [No problem, feel free to raise an issue](https://github.com/pazznetwork/ngx-chat/issues/new).


## Get Involved

### Development

**WARNING**
Pay attention to your imports in the testing app:
`'@pazznetwork/ngx-chat'` instead
of `'../../../projects/pazznetwork/ngx-chat/src/lib/services/adapters/xmpp/plugins/multi-user-chat.plugin'`

**Pull requests are welcome!**

The source code for ngx-chat can be found in the `projects/pazznetwork/ngx-chat` folder. The demo application is in the `src` folder in the
project root.

```bash
# clone this repository
git clone git@github.com:pazznetwork/ngx-chat.git
cd ngx-chat

# install dependencies
npm install

# build the library continuously
ng build @pazznetwork/ngx-chat --watch

# (in another terminal) build the sample app continuously
# will run the demo application on
# http://localhost:4200
ng serve
```

### Build the plugin

`npm run build-lib`

### Test the integration of your project with the plugin

`$fileOutDirPath` is your `npm run build` out-dir path

`npm install $fileOutDirPath`

### Run the plugin tests

`npm run test:once`

### Committing

For clean and standardised commit messages we use commit lint, for the format see: https://www.conventionalcommits.org/en/v1.0.0/.

### Releasing

`npm run build-lib` is necessary because otherwise creates a package with ngcc and throws on publish the following error:  
`trying to publish a package that has been compiled by ngcc`

```bash
# increment version number in projects/pazznetwork/ngx-chat/package.json
VERSION=0.14.13 # change accordingly
npm run changelog
git add .
git commit -m "docs: release $VERSION"
git tag v$VERSION
git push origin master --tags
./push-release.sh
```
