Package Exports

api-consumption-layer

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (api-consumption-layer) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

API Consumption Layer

Package created to implement an abstract of consumption layer for RestAPI in Angular projects for equals or later versions to 7.

Stats

Why?

We know that angular is component oriented but over time and with project growth, if there is no basic design organization, it will get confusing and difficult to maintain. So in order to improve maintenance and start a project in a structured way, I created this package.

Install

Run the command: npm i api-consumption-layer --save

After install packege, you need to create a model and service, for example:

Model [product.model.ts]

 export  class  Product {
        id: number;
        name: string;
        description: string;
        providerId: number;
        subCategoriaId: number;
        unity: string;
        initialInventory: string;
        previousBalance: string;
        currentBalance: string;
        cost: string;
        price: string;
        status: number;
}

Service [product.service.ts]

import { Injectable } from '@angular/core';
import { CoreApiService } from 'api-consumption-layer';
import { Product  as Entity } from  '../models/product.model';

/* Path da API */
const resourceName:  string  =  'products';

@Injectable({
    providedIn:  'root'
})
export  class  ProductService {
    constructor(public  restApi:  CoreApiService<Entity>) {
        this.restApi.setResource(resourceName);
    }
}

You can use this service like this:

Component [CartComponent.ts]

import { Component, OnInit } from  '@angular/core';
import { ProductService } from  'src/app/services/product.service';
import { Product } from  'src/app/models/product.model';

@Component({
    selector:  'app-cart',
    templateUrl:  './cart.component.html',
    styleUrls: ['./cart.component.scss']
})

export  class  CartComponent  implements  OnInit {
    dataSource: Product[];
    isLoadingResults: boolean;

    constructor(private productService: ProductService) { }

    ngOnInit() {
        this.productService.restApi.get().subscribe(res  => {
            this.dataSource = res;
            console.log(this.dataSource);
            this.isLoadingResults =  false;
        }, err  => {
            console.log(err);
            this.isLoadingResults =  false;
        });
    }
}
