# Alfresco Angular 2 Components core
## Prerequisites
Before you start using this development framework, make sure you have installed all required software and done all the
necessary configuration, see this [page](https://github.com/Alfresco/alfresco-ng2-components/blob/master/PREREQUISITES.md).
## Install
```sh
npm install --save ng2-alfresco-core
```
## Main components and services
### Components
- Context Menu directive
- Material Design directives
- [mdl]
- [alfresco-mdl-button]
- [alfresco-mdl-menu]
- [alfresco-mdl-tabs]
### Services
- **LogService**, log service implementation
- **NotificationService**, Notification service implementation
- **AlfrescoApiService**, provides access to Alfresco JS API instance
- **AlfrescoAuthenticationService**, main authentication APIs
- **AlfrescoTranslationService**, various i18n-related APIs
- **ContextMenuService**, global context menu APIs
## Alfresco Api Service
Provides access to initialized **AlfrescoJSApi** instance.
```ts
export class MyComponent implements OnInit {
constructor(private apiService: AlfrescoApiService) {
}
ngOnInit() {
let nodeId = 'some-node-id';
let params = {};
this.getAlfrescoApi().nodes
.getNodeChildren(nodeId, params)
.then(result => console.log(result));
}
}
```
**Note for developers**: _the TypeScript declaration files for Alfresco JS API
are still under development and some Alfresco APIs may not be accessed
via your favourite IDE's intellisense or TypeScript compiler.
In case of any TypeScript type check errors you can still call any supported
Alfresco JS api by casting the instance to `any` type like the following:_
```ts
let apiService: any = this.authService.getAlfrescoApi();
apiService.nodes.addNode('-root-', body, {});
```
## Notification Service
The Notification Service is implemented on top of the Angular 2 Material Design snackbar.
Use this service to show a notification message, and optionaly get feedback from it.
```ts
import { NotificationService } from 'ng2-alfresco-core';
export class MyComponent implements OnInit {
constructor(private notificationService: NotificationService) {
}
ngOnInit() {
this.notificationService.openSnackMessage('test', 200000).afterDismissed().subscribe(() => {
console.log('The snack-bar was dismissed');
});
}
}
```
```ts
import { NotificationService } from 'ng2-alfresco-core';
export class MyComponent implements OnInit {
constructor(private notificationService: NotificationService) {
}
ngOnInit() {
this.notificationService.openSnackMessageAction('Do you want to report this issue?', 'send', 200000).afterDismissed().subscribe(() => {
console.log('The snack-bar was dismissed');
});
}
}
```
## Context Menu directive
_See **Demo Shell** or **DocumentList** implementation for more details and use cases._
```html
```
```ts
@Component({
selector: 'my-component
})
export class MyComponent implements OnInit {
menuItems: any[];
constructor() {
this.menuItems = [
{ title: 'Item 1', subject: new Subject() },
{ title: 'Item 2', subject: new Subject() },
{ title: 'Item 3', subject: new Subject() }
];
}
ngOnInit() {
this.menuItems.forEach(l => l.subject.subscribe(item => this.commandCallback(item)));
}
commandCallback(item) {
alert(`Executing ${item.title} command.`);
}
}
```
## Authentication Service
The authentication service is used inside the [login component](../ng2-alfresco-login) and is possible to find there an example of how to use it.
```ts
import { NgModule, Component } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { CoreModule, AlfrescoSettingsService, AlfrescoAuthenticationService } from 'ng2-alfresco-core';
@Component({
selector: 'alfresco-app-demo',
template: `
Authentication failed to ip {{ ecmHost }} with user: admin, admin
ECM
Authentication successfull to ip {{ ecmHost }} with user: admin, admin
your token is {{ tokenEcm }}
BPM
Authentication successfull to ip {{ bpmHost }} with user: admin, admin
your token is {{ tokenBpm }}
`
})
class MyDemoApp {
authenticated: boolean = false;
ecmHost: string = 'http://localhost:8080';
bpmHost: string = 'http://localhost:9999';
tokenBpm: string;
tokenEcm: string;
constructor(public alfrescoAuthenticationService: AlfrescoAuthenticationService,
private alfrescoSettingsService: AlfrescoSettingsService) {
alfrescoSettingsService.ecmHost = this.ecmHost;
alfrescoSettingsService.bpmHost = this.bpmHost;
alfrescoSettingsService.setProviders('ALL');
}
ngOnInit() {
this.login();
}
login() {
this.alfrescoAuthenticationService.login('admin', 'admin').subscribe(
token => {
this.tokenBpm = this.alfrescoAuthenticationService.getTicketBpm();
this.tokenEcm = this.alfrescoAuthenticationService.getTicketEcm();
this.authenticated = true;
},
error => {
console.log(error);
this.authenticated = false;
});
}
}
@NgModule({
imports: [
BrowserModule,
CoreModule.forRoot()
],
declarations: [MyDemoApp],
bootstrap: [MyDemoApp]
})
export class AppModule {
}
platformBrowserDynamic().bootstrapModule(AppModule);
```
## AlfrescoTranslationService
In order to enable localisation support you will need creating a `/resources/i18n/en.json` file
and registering path to it's parent `i18n` folder:
```ts
class MainApplication {
constructor(private translateService: AlfrescoTranslationService) {
translateService.addTranslationFolder('app', 'resources');
}
}
```
Service also allows changing current language for entire application.
Imagine you got a language picker that invokes `onLanguageClicked` method:
```ts
class MyComponent {
constructor(private translateService: AlfrescoTranslationService) {
}
onLanguageClicked(lang: string) {
this.translateService.use('en');
}
}
```
It is also possible providing custom translations for existing components by overriding their resource paths:
```ts
class MyComponent {
constructor(private translateService: AlfrescoTranslationService) {
translateService.addTranslationFolder(
'ng2-alfresco-login',
'i18n/custom-translation/alfresco-login'
);
}
}
```
**Important note**: `addTranslationFolder` method redirects **all** languages to a new folder, you may need implementing multiple languages
or copying existing translation files to a new path.
## Renditions Service
* getRenditionsListByNodeId(nodeId: string)
* createRendition(nodeId: string, encoding: string)
* getRendition(nodeId: string, encoding: string)
* isRenditionAvailable(nodeId: string, encoding: string)
## Build from sources
Alternatively you can build component from sources with the following commands:
```sh
npm install
npm run build
```
## Build from sources
Alternatively you can build component from sources with the following commands:
```sh
npm install
npm run build
```
### Build the files and keep watching for changes
```sh
$ npm run build:w
```
## Running unit tests
```sh
npm test
```
### Running unit tests in browser
```sh
npm test-browser
```
This task rebuilds all the code, runs tslint, license checks and other quality check tools
before performing unit testing.
### Code coverage
```sh
npm run coverage
```
