MessageTemplates Microservice Client SDK for Dart

This is a Dart client SDK for pip-services-msgtemplates 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-content/pip-clients-msgtemplates-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 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);
}

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 = 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}
