Settings Microservice #

This is a settings microservice from Pip.Services library. It manages system settings separated by individual sections. Each section contains multiple key-value parameter pairs.

The microservice currently supports the following deployment options:

  • Deployment platforms: Standalone Process
  • External APIs: HTTP/REST
  • 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.

class SettingsSectionV1 implements IStringIdentifiable {
  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);

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-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.

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: "pip-services-settings"
  description: "Settings microservice"

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

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

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

- descriptor: "pip-services-settings:service:http:default:1.0"
    protocol: "http"
    host: ""
    port: 8080

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 and pip_clients_settings packages

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

Define client configuration parameters that match configuration of the microservice 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();

// Configure the client

// Connect to the microservice
  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
// Get section parameters
var parameters = client.getSectionById(
