User Accounts Microservice

This is a user account management microservice from Pip.Services library.

• Registers users and creates their accounts
• Keeps key user descriptions and settings (about, location, language, theme, ...)

The microservice currently supports the following deployment options:

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

This microservice has optional dependencies on the following microservices:

• pip-services3-activities-node - to log user activities (signup, signin, change settings)

  • HTTP Version 1
  • Seneca Version 1

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.

class AccountV1 implements IStringIdentifiable {
    /* Identification */
    public id: string;
    public login: string;
    public name: string;

    /* Activity tracking */
    public create_time: Date;
    public active: boolean;

    /* User preferences */
    public time_zone: string;
    public language: string;
    public theme: string;

    /* Custom fields */
    public custom_hdr: any;
    public custom_dat: any;
}

interface IAccountsV1 {
    getAccounts(correlationId: string, filter: FilterParams, paging: PagingParams,
        callback: (err: any, page: DataPage<AccountV1>) => void): void;

    getAccountById(correlationId: string, id: string,
        callback: (err: any, account: AccountV1) => void): void;

    getAccountByLogin(correlationId: string, login: string,
        callback: (err: any, account: AccountV1) => void): void;

    getAccountByIdOrLogin(correlationId: string, idOrLogin: string,
        callback: (err: any, account: AccountV1) => void): void;

    createAccount(correlationId: string, account: AccountV1,
        callback: (err: any, account: AccountV1) => void): void;

    updateAccount(correlationId: string, account: AccountV1,
        callback: (err: any, account: AccountV1) => void): void;

    deleteAccountById(correlationId: string, id: string,
        callback: (err: any, account: AccountV1) => void): void;
}

Download

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

git clone git@github.com:pip-services-users/pip-services-accounts-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-services3-container:container-info:default:default:1.0"
  name: "pip-services-accounts"
  description: "User accounts microservice"

- descriptor: "pip-services3-commons:logger:console:default:1.0"
  level: "trace"

- descriptor: "pip-services-accounts:persistence:file:default:1.0"
  path: "./data/accounts.json"

- descriptor: "pip-services-accounts:controller:default:default:1.0"

- descriptor: "pip-services-accounts: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": {
        ....
        "pip-clients-accounts-node": "^1.0.*",
        ...
    }
}

Inside your code get the reference to the client SDK

var sdk = new require('pip-clients-accounts-node');

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

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

Instantiate the client and open connection to the microservice

// Create the client instance
var client = sdk.UsersHttpClientV1(config);

// Connect to the microservice
client.open(null, function(err) {
    if (err) {
        console.error('Connection to the microservice failed');
        console.error(err);
        return;
    }
    
    // Work with the microservice
    ...
});

Now the client is ready to perform operations

// Register a new user
client.createUser(
    null,
    { 
        name: 'Test User',
        email: 'somebody@somewhere.com'
    },
    function (err, user) {
        ...
    }
);

// Get the user account
client.getUserByEmail(
    null,
    'somebody@somewhere.com',
    function(err, user) {
    ...    
    }
);
