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:

Pip.Services3.Commons
Pip.Services3.Rpc

Add pip-services3-commons-dart, pip-services3-rpc-dart and pip_services_activities packages
import 'package:pip_services3_commons/pip_services3_commons.dart';
import 'package:pip_services3_rpc/pip_services3_rpc.dart';

import 'package:pip_services_activities/pip_services_activities.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
);
copied to clipboard
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
// ...
copied to clipboard
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...
}
copied to clipboard
// 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}
