Contract #

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

class MessageTemplateV1 implements IStringIdentifiable {  
  String id;  
  String name;
  String from;
  MultiString subject;
  MultiString text;
  MultiString html;
  String status;
}

class MessageTemplateStatusV1 {
  static final New = 'new';
  static final Writing = 'writing';
  static final Translating = 'translating';
  static final Verifying = 'verifying';
  static final Completed = 'completed';
}

abstract class IMessageTemplatesV1 {
  Future<DataPage<TemplateV1>> getTemplates(
      String correlationId, FilterParams filter, PagingParams paging);

  Future<TemplateV1> getTemplateById(String correlationId, String id);

  Future<TemplateV1> getTemplateByIdOrName(String correlationId, String idOrName);

  Future<TemplateV1> createTemplate(String correlationId, TemplateV1 msgtemplate);

  Future<TemplateV1> updateTemplate(String correlationId, TemplateV1 msgtemplate);

  Future<TemplateV1> deleteTemplateById(String correlationId, String msgtemplateId);
}

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_msgtemplates packages

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

import 'package:pip_services_msgtemplates/pip_services_msgtemplates.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 = TemplatesHttpClientV1(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 msgtemplate
final TEMPLATE = MessageTemplateV1(
    id: '1',
    name: 'template1',
    from: null,
    subject: MultiString({ 'en': 'Text 1' }),
    text: MultiString({ 'en': 'Text 1' }),
    html: MultiString({ 'en': 'Text 1' }),
    status: MessageTemplateStatusV1.Completed);

    // Create the msgtemplate
    try {
      var msgtemplate = await client.createTemplate('123', TEMPLATE);
      // Do something with the returned msgtemplate...
    } catch(err) {
      // Error handling...     
    }
// Get the msgtemplate
try {
var msgtemplate = await client.getTemplateByIdOrName(
    null,
    'template1');
    // Do something with msgtemplate...

    } catch(err) { // Error handling}
