Reactive XComponent API

Reactive XComponent is a javaScript client API that allows you to interact with microservices generated with XComponent software.

Install

install the latest version of the API:

npm : npm i reactivexcomponent.js --save

yarn : yarn add reactivexcomponent.js

Usage

Import in JS :

import xcomponent from 'reactivexcomponent.js';

Import in TS :

import { XComponent } from 'reactivexcomponent.js';
const xcomponent = new XComponent();

Set/Get LogLevel of the API :

import { LogLevel } from 'reactivexcomponent.js';

xcomponent.setLogLevel(LogLevel.DEBUG);
const logLevel = xcomponent.getLogLevel();

Connect to XComponent WebSocket Bridge :

const serverUrl = 'ws://localhost:443';

xcomponent.connect(serverUrl)
.then(connection => {
    // Here goes your code that uses the connection
});

Get the list of available APIs on the WebSocket Bridge :

connection.getXcApiList().then(apiList => {
    apiList.forEach(api => console.log('Available Api : ' + api));
});

Create a Session on a specific API :

const xcApiName = "HelloWorldApi.xcApi"

connection.createSession(xcApiName)
.then(session => {
    // Here goes your code that uses the session
});

Variables used in the following examples :

const componentName = "HelloWorld";
const stateMachineName = "HelloWorldManager";
const stateMachineResponse = "HelloWorldResponse";

const jsonMessage = { "Name": "Test" };
const messageType = "XComponent.HelloWorld.UserObject.SayHello";

Get the Snapshot using a Session :

session.getSnapshot(componentName, stateMachineName)
.then(snapshot => {
    snapshot.forEach(snapshotElement => console.log('Element : ' + snapshotElement));
});

Get StateMachine updates through an Observable using a Session :

const updates$ = session.getStateMachineUpdates(componentName, stateMachineResponse);

Send a message to all instances of a state machine using a Session :

// You can use the method canSend to check if the session is alowed the send this event to this state machine.
if (session.canSend(componentName, stateMachineName, messageType)) {
    session.send(componentName, stateMachineName, messageType, jsonMessage);
}

Send a message to a specific state machine instance using a StateMachineInstance or StateMachineRef :

stateMachineInstance.send(messageType, jsonMessage);
