Activities Microservice Client SDK for Dart

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

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-clients-activities-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 PartyActivityV1 implements IStringIdentifiable {
  /* Identification */
  String id;
  String org_id;

  /* Identification fields */
  DateTime time;
  String type;
  ReferenceV1 party;

  /* References objects (notes, goals, etc.) */
  ReferenceV1 ref_item;
  List<ReferenceV1> ref_parents;
  ReferenceV1 ref_party;

  /* Other details like % of progress or new status */
  StringValueMap details;
}

class ReferenceV1 implements IStringIdentifiable {
  String id;
  String type;
  String name;
}

abstract class IActivitiesV1 {
  Future<DataPage<PartyActivityV1>> getPartyActivities(
      String correlationId, FilterParams filter, PagingParams paging);

  Future<PartyActivityV1> logPartyActivity(String correlationId, PartyActivityV1 activity);

  Future<List<PartyActivityV1>> batchPartyActivities(String correlationId, List<PartyActivityV1> activities);

  Future deletePartyActivities(String correlationId, dynamic filter);
}

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 = ActivitiesHttpClientV1(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 activity
final ACTIVITY = PartyActivityV1({
        type: 'signup',
        party: {
            id: '123',
            name: 'Test User'
        }
});

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

// Get the list of activities for 'My Samples' product
var now = new Date();
try {
var page = await client.getPartyActivities(
    null,
    {
        party_id: '123',
        from_time: new Date(now.getTime() - 24 * 3600 * 1000),
        to_time: now
    },
    {
        total: true,
        skip: 0,
        take: 10
    });
    // Do something with page...

    } catch(err) { // Error handling}
