# Eccenca Message Bus for inter-component and in-app communications

`ecc-messagebus` exports a normal rxmq.js instance but with a set of additional functions.

For convenience it also exports `Rx` so that we can use a fixed `Rx` version in all components.

## Using Rx

```js

import {Rx} from 'ecc-messagebus';

var source = Rx.Observable.just(42);

var subscription = source.subscribe(

  function (x) {

    console.log(`Next: ${x}');

  },

  function (err) {

    console.log(`Error: ${err}`);

  },

  function () {

    console.log('Completed');

  });

// => Next: 42

// => Completed

```

## Using request-response

Request-response pattern can be used like so:

```js

import rxmq from 'ecc-messagebus';

// ...

// get channel

const channel = rxmq.channel('yourChannel');

// subscribe to topic

channel.subject('someTopic').subscribe(({data, replySubject}) => {

    // ...

    // use envelop.reply to send response

    replySubject.onNext({some: 'response'});

    replySubject.onCompleted();

});

// ...

// initiate request and handle response as a promise

channel.request({

    topic: 'someTopic',

    data: {test: 'test'},

    timeout: 2000

})

.subscribe((data) => {

    // work with data here

    // ...

},

(err) => {

    // catch and handle error here

    // ...

});

```
