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:

Contract

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

class AccountV1 implements IStringIdentifiable {
  /* Identification */
  String id;
  String login;
  String name;
  
  /* Activity tracking */
  DateTime create_time;
  bool deleted;
  bool active;

  /* User preferences */
  String about;
  String time_zone;
  String language;
  String theme;

  /* Custom fields */
  var custom_hdr;
  var custom_dat;
}

abstract class IAccountsV1 {
  Future<DataPage<AccountV1>> getAccounts(
      String correlationId, FilterParams filter, PagingParams paging);

  Future<AccountV1> getAccountById(String correlationId, String id);

  Future<AccountV1> getAccountByLogin(String correlationId, String login);

  Future<AccountV1> getAccountByIdOrLogin(String correlationId, String idOrLogin);

  Future<AccountV1> createAccount(String correlationId, AccountV1 account);

  Future<AccountV1> updateAccount(String correlationId, AccountV1 account);

  Future<AccountV1> deleteAccountById(String correlationId, String accountId);
}

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-dart.git

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

Run

Add config.yaml file to the root of the microservice folder and set configuration parameters.

For more information on the microservice configuration see Configuration Guide.

Start the microservice using the command:

dart ./bin/run.dart

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 dart, then get references to the required libraries:

Add pip-services3-commons-dart, pip-services3-rpc-dart and pip-services_accounts packages

import 'package:pip_services3_commons/pip_services3_commons.dart';
import 'package:pip_services3_rpc/pip_services3_rpc.dart';

import 'package:pip_services_accounts/pip_services_accounts.dart';

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

// Client configuration
var httpConfig = ConfigParams.fromTuples(
	"connection.protocol", "http",
	"connection.host", "localhost",
	"connection.port", 8080
);

Instantiate the client and open connection to the microservice

// Create the client instance
var client = AccountsHttpClientV1(config);

// Configure the client
client.configure(httpConfig);

// Connect to the microservice
try{
  await client.open(null)
}catch() {
  // Error handling...
}       
// Work with the microservice
// ...

Now the client is ready to perform operations

// Create a new account
final ACCOUNT = AccountV1(
    id: '1',
    login: 'user1@conceptual.vision',
    name: 'Test User 1',
    deleted: false
);

    // Create the account
    try {
      var account = await client.createAccount('123', ACCOUNT);
      // Do something with the returned account...
    } catch(err) {
      // Error handling...     
    }

// Get the account
try {
var account = await client.getAccountByLogin(
    null,
    'somebody@somewhere.com');
    // Do something with account...

    } catch(err) { // Error handling}
