angular-rest

Angular2 HTTP client to consume RESTful services. Built on @angular/http with TypeScript.
Note: Production Ready! (Well tested)

Installation

npm install git+https://github.com/Dmitry-Gorbenko/angular-rest --save

Example

import {Http, Request, Response} from '@angular/http';
import {HttpClient, RESTClient, Client, GET, PUT, POST, DELETE, Headers, Path, Body, Query, Produces, MediaType} from 'angular-rest';

import {Todo} from './models/Todo';
import {SessionFactory} from './sessionFactory';

@Injectable()
@Client({
    serviceId: 'todo-service',
    baseUrl: 'http://localhost:3000/api/',
    headers: {
        'content-type': 'application/json'
    }
})
export class TodoClient extends RestClient {

    constructor(http:Http){
        super(<HttpClient>http);
    }

    protected requestInterceptor(req: Request):void {
        if (SessionFactory.getInstance().isAuthenticated) {
            req.headers.append('jwt', SessionFactory.getInstance().credentials.jwt);
        }
    }
    
    protected responseInterceptor(res: Observable<Response>): Observable<any> {
        // do anything with responses
        return res;
    }

    @Get("todo/")
    @Timeout(2000) //In milliseconds
    @Produces(MediaType.JSON)
    public getTodos( @Query("page") page:number, @Query("size", {default: 20}) size?:number, @Query("sort") sort?: string): Observable<Todo[]> { return null; };

    @Get("todo/{id}")
    @Timeout(2000) //In milliseconds
    @Map(resp => new Todo(resp.json()))
    public getTodoById( @Path("id") id: number): Observable<Todo>{ return null; };

    @Post("todo")
    @Timeout(2000) //In milliseconds
    @Headers({
        'content-type': 'application/json'
    })
    public postTodo( @Body todo: Todo): Observable<Response> { return null; };

    @Put("todo/{id}")
    @Timeout(2000) //In milliseconds
    public putTodoById( @Path("id") id: string, @Body todo: Todo): Observable<Response> { return null; };

    @Delete("todo/{id}")
    @Timeout(2000) //In milliseconds
    public deleteTodoById( @Path("id") id: string): Observable<Response> { return null; };

}

Using it in your component

app.module.ts

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    HttpModule
  ],
  providers: [
    TodoClient
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

todo.component.ts

@Component({
  selector: 'to-do',
})
export class ToDoCmp {

  constructor(private todoClient: TodoClient) {
  }
  
  //Use todoClient
}

API Docs

RESTClient

Methods:

• getServiceId(): string: returns the serviceId of the RestClient
• getBaseUrl(): string: returns the base url of RestClient
• getDefaultHeaders(): Object: returns the default headers of RestClient in a key-value pair

Class decorators:

• @Client(args:{serviceId?: string, baseUrl?: string, headers?: any})

Method decorators:

• @Get(url: String)
• @Post(url: String)
• @Put(url: String)
• @Patch(url: String)
• @Delete(url: String)
• @Head(url: String)
• @Headers(headers: Object)
• @Map(mapper:(resp : any)=>any)
• @OnEmit(emitter:(resp : Observable<any>)=>Observable<any>)
• @Timeout(timeout: number)

Parameter decorators:

• @Path(name: string, value?:any|{value?:any})
• @Query(name: string, value?:any|{value?:any,format?:string})
• @Header(name: string, value?:any|{value?:any,format?:string})
• @Body

Collection Format

Determines the format of the array if type array is used. (used for @Query and @Header) Possible values are:

• Format.CSV - comma separated values foo,bar.
• Format.SSV - space separated values foo bar.
• Format.TSV - tab separated values foo\tbar.
• Format.PIPES - pipe separated values foo|bar.
• Format.MULTI - corresponds to multiple parameter instances instead of multiple values for a single instance foo=bar&foo=baz. This is valid only for parameters in "query" or "formData".

Default value is Format.CSV.
