Download

Right now the only way to get the microservice is to check it out directly from github repository

git clone [email protected]:pip-services-ecommerce2/service-purchaseorders-node.git

Pip.Service team is working to implement packaging and make stable releases available for your as zip downloadable archieves.

Run

Add config.yml file to the root of the microservice folder and set configuration parameters. As the starting point you can use example configuration from config.example.yml file.

Example of microservice configuration

- descriptor: "pip-services-container:container-info:default:default:1.0"
  name: "service-purchaseorders"
  description: "PurchaseOrders microservice"

- descriptor: "pip-services-commons:logger:console:default:1.0"
  level: "trace"

- descriptor: "service-purchaseorders:persistence:file:default:1.0"
  path: "./data/purchase_orders.json"

- descriptor: "service-purchaseorders:controller:default:default:1.0"

- descriptor: "service-purchaseorders:service:http:default:1.0"
  connection:
    protocol: "http"
    host: "0.0.0.0"
    port: 8080

For more information on the microservice configuration see Configuration Guide.

Start the microservice using the command:

node run

Use

The easiest way to work with the microservice is to use client SDK. The complete list of available client SDKs for different languages is listed in the Quick Links

If you use Node.js then you should add dependency to the client SDK into package.json file of your project

{
    ...
    "dependencies": {
        ....
        "client-purchaseorders-node": "^1.0.*",
        ...
    }
}

Inside your code get the reference to the client SDK

let sdk = new require('client-purchaseorders-node');

Define client configuration parameters that match configuration of the microservice external API

// Client configuration
let config = {
    connection: {
        protocol: 'http',
        host: 'localhost', 
        port: 8080
    }
};

Instantiate the client and open connection to the microservice

// Create the client instance
let client = sdk.PurchaseOrdersHttpClientV1(config);

// Connect to the microservice
await client.open(null);

// Work with the microservice
    ...

Now the client is ready to perform operations

// Create a new purchase_order
let purchase_order = {
    id: '1',
    customer_id: '1',
    currency_code: 'USD',
    total: 100,
    state: PurchaseOrderStateV1.New,
    items: [{
        price: 40,
        product_id: 'product-1',
        product_name: 'product name 1',
        quantity: 2,
        total: 80,
        description: 'desctiption for product 1',
    },
    {
        price: 20,
        product_id: 'product-2',
        product_name: 'product name 2',
        quantity: 1,
        total: 20,
        description: 'desctiption for product 2',
    }]
};

purchase_order = await client.createOrder(
    null,
    purchase_order
);

// Get the list of purchase_orders
let page = await client.getOrders(
    null,
    {
        customer_id: '1',
        state: 'new'
    },
    {
        total: true,
        skip: 0,
        take: 10
    }
);
