Applications microservice #

This is applications microservice from Pip.Services library. It keeps a list of supported applications that are referenced from other content microservices.

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), please, refer to documentation of the specific protocol.

class ApplicationV1 implements IStringIdentifiable {
  String id;
  MultiString name;
  MultiString description;
  String product;
  String group;
  String copyrights;
  String url;
  String icon;
  int min_ver;
  int max_ver;
}

abstract class IApplicationsClientV1 {
  Future<DataPage<ApplicationV1>> getApplications(
      String correlationId, FilterParams filter, PagingParams paging);

  Future<ApplicationV1> getApplicationById(String correlationId, String applicationId);

  Future<ApplicationV1> createApplication(String correlationId, ApplicationV1 application);

  Future<ApplicationV1> updateApplication(
    String correlationId,
    ApplicationV1 application,
  );

  Future<ApplicationV1> deleteApplicationById(String correlationId, String applicationId);
}

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-content/pip-services-applications-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_applications packages

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

import 'package:pip_services_applications/pip_services_applications.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 = ApplicationsHttpClientV1(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 application
final APPLICATION = ApplicationV1.fromMap({
    id: 'my_app',
    name: 'My Application',
    product: 'My Samples'
});

    // Create the application
    try {
      var application = await client.createApplication('123', APPLICATION);
      // Do something with the returned application...
    } catch(err) {
      // Error handling...     
    }
// Get the list of applications for 'My Samples' product
try {
var page = await client.getApplications(
    null,
    {
        product: 'My Samples'
    },
    {
        total: true,
        skip: 0,
        take: 10
    });
    // Do something with page...

    } catch(err) { // Error handling}

Examples for Applications Microservice #

This is applications microservice from Pip.Services library. It keeps a list of supported applications that are referenced from other content microservices.

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

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

Instantiate the service

persistence = ApplicationsMemoryPersistence();
persistence.configure(ConfigParams());

controller = ApplicationsController();
controller.configure(ConfigParams());

service = ApplicationsHttpServiceV1();
service.configure(httpConfig);

var references = References.fromTuples([
    Descriptor('pip-services-applications', 'persistence', 'memory',
        'default', '1.0'),
    persistence,
    Descriptor('pip-services-applications', 'controller', 'default',
        'default', '1.0'),
    controller,
    Descriptor(
        'pip-services-applications', 'service', 'http', 'default', '1.0'),
    service
]);

controller.setReferences(references);
service.setReferences(references);

await persistence.open(null);
await service.open(null);

Instantiate the client and open connection to the microservice

// Create the client instance
var client = ApplicationsHttpClientV1(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 application
final APPLICATION = ApplicationV1.fromMap({
    id: 'my_app',
    name: 'My Application',
    product: 'My Samples'
});

    // Create the application
    try {
      var application = await client.createApplication('123', APPLICATION);
      // Do something with the returned application...
    } catch(err) {
      // Error handling...     
    }
// Get the list of applications for 'My Samples' product
try {
var page = await client.getApplications(
    null,
    {
        product: 'My Samples'
    },
    {
        total: true,
        skip: 0,
        take: 10
    });
    // Do something with page...

    } catch(err) { // Error handling}

In the help for each class there is a general example of its use. Also one of the quality sources are the source code for the tests.
