service-processstates-node v1.0.0

Process states microservice

This is process states microservice from Pip.Services library. It stores customer process states internally or in external PCI-complient service like Paypal

The microservice currently supports the following deployment options:

• Deployment platforms: Standalone Process, Seneca
• External APIs: HTTP/REST, Seneca
• Persistence: Flat Files, MongoDB

This microservice has no dependencies on other microservices.

Contract

Logical contract of the microservice is presented below. For physical implementation (HTTP/REST, Thrift, Seneca, Lambda, etc.), please, refer to documentation of the specific protocol.

    public line1: string;
    public line2?: string;
    public city: string;
    public postal_code?: string;
    public postal_code?: string;

    getStateById(correlationId: string, state_id: string): Promise<ProcessStateV1>;

    createState(correlationId: string, state: ProcessStateV1): Promise<ProcessStateV1>;

Download

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

git clone git@github.com:pip-services-integration2/service-processstates-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-processstates"
  description: "ProcessStates microservice"

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

- descriptor: "service-processstates:persistence:file:default:1.0"
  path: "./data/process_states.json"

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

- descriptor: "service-processstates: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-processstates-node": "^1.0.*",
        ...
    }
}

Inside your code get the reference to the client SDK

let sdk = new require('client-processstates-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 active connection to the microservice

// Create the client instance
let client = sdk.ProcessStatesHttpClientV1(config);

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

// Work with the microservice
...

Now the client is ready to perform operations

// Create a new process_state
let process_state = {
    customer_id: '1',
    type: 'visa',
    number: '1111111111111111',
    expire_month: 1,
    expire_year: 2021,
    first_name: 'Bill',
    last_name: 'Gates',
    billing_address: {
        line1: '2345 Swan Rd',
        city: 'Tucson',
        postal_code: '85710',
        country_code: 'US'
    },
    ccv: '213',
    name: 'Test State 1',
    saved: true,
    default: true,
    state: 'ok'
};

process_state = await client.createState(
    null,
    process_state
);

// Get the list of process_states on 'time management' topic
let page = await client.getStates(
    null,
    {
        customer_id: '1',
        state: 'ok'
    },
    {
        total: true,
        skip: 0,
        take: 10
    }
);
