Applications microservice

This is applications microservice from Pip.Services library. It keeps a list of supported applications that are referenced from other content microservices.

The microservice currently supports the following deployment options:

  • Deployment platforms: Standalone Process, Seneca
  • External APIs: HTTP/REST, Seneca
  • Persistence: Flat Files, MongoDB

This microservice has no dependencies on other microservices.

Contract

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

class ApplicationV1 implements IStringIdentifiable {
    public id: string;
    public name: string;
    public description: string;
    public product: string;
    public copyrights: string;
    public min_ver: number;
    public max_ver: number;
}
 
interface IApplicationsV1 {
    getApplications(correlationId: string, filter: FilterParams, paging: PagingParams, 
        callback: (err: any, page: DataPage<ApplicationV1>) => void): void;
 
    getApplicationById(correlationId: string, application_id: string, 
        callback: (err: any, application: ApplicationV1) => void): void;
 
    createApplication(correlationId: string, application: ApplicationV1, 
        callback: (err: any, application: ApplicationV1) => void): void;
 
    updateApplication(correlationId: string, application: ApplicationV1, 
        callback: (err: any, application: ApplicationV1) => void): void;
 
    deleteApplicationById(correlationId: string, application_id: string,
        callback: (err: any, application: ApplicationV1) => void): void;
}

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-services-applications-node.git

Pip.Service team is working to implement packaging and make stable releases available for your as zip downloadable archieves.

Run

Add config.yaml file to the root of the microservice folder and set configuration parameters. As the starting point you can use example configuration from config.example.yaml file.

Example of microservice configuration

descriptor: "pip-services-container:container-info:default:default:1.0"
  name: "pip-services-applications"
  description: "Applications microservice"
 
descriptor: "pip-services-commons:logger:console:default:1.0"
  level: "trace"
 
descriptor: "pip-services-applications:persistence:file:default:1.0"
  path: "./data/applications.json"
 
descriptor: "pip-services-applications:controller:default:default:1.0"
 
descriptor: "pip-services-applications:service:http:default:1.0"
  connection:
    protocol: "http"
    host: "0.0.0.0"
    port: 8080

For more information on the microservice configuration see Configuration Guide.

Start the microservice using the command:

node run

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 Node.js then you should add dependency to the client SDK into package.json file of your project

{
    ...
    "dependencies": {
        ....
        "pip-clients-applications-node": "^1.1.*",
        ...
    }
}

Inside your code get the reference to the client SDK

var sdk = new require('pip-clients-applications-node');

Define client configuration parameters that match configuration of the microservice external API

// Client configuration
var config = {
    connection: {
        protocol: 'http',
        host: 'localhost', 
        port: 8080
    }
};

Instantiate the client and open connection to the microservice

// Create the client instance
var client = sdk.ApplicationsHttpClientV1(config);
 
// Connect to the microservice
client.open(null, function(err) {
    if (err) {
        console.error('Connection to the microservice failed');
        console.error(err);
        return;
    }
    
    // Work with the microservice
    ...
});

Now the client is ready to perform operations

// Create a new application
var application = {
    id: 'my_app',
    name: 'My Application',
    product: 'My Samples'
};
 
client.createApplication(
    null,
    application,
    function (err, application) {
        ...
    }
);
// Get the list of applications for 'My Samples' product
client.getApplications(
    null,
    {
        product: 'My Samples'
    },
    {
        total: true,
        skip: 0,
        take: 10
    },
    function(err, page) {
    ...    
    }
);
