Settings Microservice Client SDK for Dart

This is a Dart client SDK for pip-services-settings microservice.

Download

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

git clone [e-mail]:pip-services-infrastructure/pip-services-settings-dart.git

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

Contract

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

class SettingsSectionV1 implements IStringIdentifiable {
  @override
  String id;
  ConfigParams parameters;
  DateTime update_time;

  SettingsSectionV1({String id, ConfigParams parameters, DateTime update_time});

  void fromJson(Map<String, dynamic> json);
  Map<String, dynamic> toJson();
}


abstract class ISettingsClientV1 {
  Future<DataPage<String>> getSectionIds(String correlationId, FilterParams filter, PagingParams paging);
  Future<DataPage<SettingsSectionV1>> getSections(String correlationId, FilterParams filter, PagingParams paging);
  Future<ConfigParams> getSectionById(String correlationId, String id);
  Future<ConfigParams> setSection(String correlationId, String id, ConfigParams parameters);
  Future<ConfigParams> modifySection(String correlationId, String id, ConfigParams updateParams, ConfigParams incrementParams);
}

Use

The easiest way to work with the microservice is to use client SDK.

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 = SettingsHttpClientV1(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

var parameters = ConfigParams.fromTuples([
                    'myapp', ConfigParams.fromTuples([
                      'theme', 'blue',
                      'language', 'en'
                    ])
                 ]);

// Sets section parameters
client.setSection(
    null,
    '123',
    parameters
);

// Get section parameters
var parameters = client.getSectionById(
    null,
    '123'
);
