Jobs Microservice Client SDK for Dart #

This is a Dart client SDK for pip-services-jobs 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-infrastructure/pip-clients-jobs-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 NewJobV1 {
  String type;
  String ref_id;
  num ttl;
  dynamic params;
}

class JobV1 implements IStringIdentifiable {
  // Job description
  String id;
  String type;
  String ref_id;
  dynamic params;

  // Job control
  DateTime created;
  DateTime started;
  DateTime locked_until;
  DateTime execute_until;
  DateTime completed;
  num retries;
}

abstract class IJobsV1 {
  Future<JobV1> addJob(String correlationId, NewJobV1 newJob);

  Future<JobV1> addUniqJob(String correlationId, NewJobV1 newJob);

  Future<DataPage<JobV1>> getJobs(
      String correlationId, FilterParams filter, PagingParams paging);

  Future<JobV1> getJobById(String correlationId, String jobId);

  Future<JobV1> startJobById(String correlationId, String jobId, num timeout);

  Future<JobV1> startJobByType(
      String correlationId, String jobType, num timeout, num maxRetries);

  Future<JobV1> extendJob(String correlationId, String jobId, num timeout);

  Future<JobV1> abortJob(String correlationId, String jobId);
  
  Future<JobV1> completeJob(String correlationId, String jobId);

  Future<JobV1> deleteJobById(String correlationId, String jobId);

  Future deleteJobs(String correlationId);

  Future cleanJobs(String correlationId);
}

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 = JobsHttpClientV1(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 job
final JOB = NewJobV1(
    type: 't1', ref_id: 'obj_0fsd', ttl: 1000 * 60 * 60 * 3, params: null);

    // Create the job
    try {
      JobV1 job1 = await client.addJob('123', JOB);
      // Do something with the returned job...
    } catch(err) {
      // Error handling...     
    }
// Get the job
try {
var job = await client.getJobByid(
    null,
    job1.id);
    // Do something with job...

    } catch(err) { // Error handling}

Examples for Jobs Microservice #

This is the jobs microservice. It keeps list of working jobs.

The service allows you to manage tasks in those cases when the generation (statement) of the task is performed in a separate microservice, and direct execution is implemented in one way or another.

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 = JobsHttpClientV1(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 job
final JOB = NewJobV1(
    type: 't1', ref_id: 'obj_0fsd', ttl: 1000 * 60 * 60 * 3, params: null);

    // Create the job
    try {
      JobV1 job1 = await client.addJob('123', JOB);
      // Do something with the returned job...
    } catch(err) {
      // Error handling...     
    }
// Get the job
try {
var job = await client.getJobByid(
    null,
    job1.id);
    // Do something with job...

    } 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.
