Microfrontends microservice

This is microfrontends microservice from Pip.Services library. It keeps a list of supported microfrontends 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 MicrofrontendV1 implements IStringIdentifiable {
    public id: string;
    public name: string;
    public description?: string;
    public path_prefix: string;
    public icon?: string;
    public type?: string;
    public remote_entry: string;
    public exposed_module: string;
    public element_name: string;
    public params?: { [key: string]: any };
}

interface IMicrofrontendsV1 {
    getMicrofrontends(correlationId: string, filter: FilterParams, paging: PagingParams): Promise<DataPage<MicrofrontendV1>>;

    getMicrofrontendById(correlationId: string, microfrontend_id: string): Promise<MicrofrontendV1>;

    createMicrofrontend(correlationId: string, microfrontend: MicrofrontendV1): Promise<MicrofrontendV1>;

    updateMicrofrontend(correlationId: string, microfrontend: MicrofrontendV1): Promise<MicrofrontendV1>;

    deleteMicrofrontendById(correlationId: string, microfrontend_id: string): Promise<MicrofrontendV1>;
}

Download

Right now the only way to get the microservice is to check it out directly from github repository

git clone [e-mail]:pip-services-content2/service-microfrontends-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: "service-microfrontends"
  description: "Microfrontends microservice"

- descriptor: "pip-services-commons:logger:console:default:1.0"
  level: "trace"

- descriptor: "service-microfrontends:persistence:file:default:1.0"
  path: "./data/microfrontends.json"

- descriptor: "service-microfrontends:controller:default:default:1.0"

- descriptor: "service-microfrontends:service:commandable-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": {
        ....
        "client-microfrontends-node": "^1.1.*",
        ...
    }
}

Inside your code get the reference to the client SDK

let sdk = new require('client-microfrontends-node');

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

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

Instantiate the client and open connection to the microservice

// Create the client instance
let client = sdk.MicrofrontendsHttpClientV1(config);

// Connect to the microservice
try {
    await client.open(null);
    // Work with the microservice
    ...
} catch (err) {
    console.error('Connection to the microservice failed');
    console.error(err);
}

Now the client is ready to perform operations

// Create a new microfrontend
let microfrontend = {
    id: 'my_app',
    name: 'My Microfrontend',
    product: 'My Samples'
};

let microfrontend = await client.createMicrofrontend(null, microfrontend);

// Get the list of microfrontends for 'My Samples' product
let page = await client.getMicrofrontends(
    null,
    {
        product: 'My Samples'
    },
    {
        total: true,
        skip: 0,
        take: 10
    }
);
