js-message

Normalized JS & JSON Message and event Protocol for node.js, vanilla.js (plain old javascript), react.js, websockets, rest api's, node-ipc, and any other protocol that might use a js object and or a JSON string.

js-message allows for seamless conversion of JSON messages and events to JS objects for a normalized implementation on the server and in the client without needing to concern yourself with JSON intermediaries and custom parsers.

Things are just easier when you normalize them.

Creating a Message Object

For the browser you can do either an import with the path to make the first http request for your module, and have it cached for other scripts thereafter OR you can import it with the <script> tag upfront which automatically loads as defer so it doesn't interrupt the parser.

<script type="module" src='/path/to/module/js-message-vanilla.js' />

Both node and the browser now support import statements. If you use relative pathing you can use the same exact code from node in the browser without even transpiling much the less bundling.

    //works for browser natively AND node natively
    import { default as Message } from './node_modules/js-message/Message.js';
    //works for browser transpiled AND node natively
    import { default as Message } from 'js-message';

    var myMessage=new Message;
    myMessage.type='message or event type';
    myMessage.data.something='something';
    myMessage.data.stuff=[1,2,3,4,5]

    console.log(myMessage.JSON);

Creating a Message From JSON

    //works for browser natively AND node natively
    import { default as Message } from './node_modules/js-message/Message.js';
    //works for browser transpiled AND node natively
    import { default as Message } from 'js-message';

    //lets say we have the above example running on
    //a websocket server sending js-messages as JSON
    //
    //and lets say this is the client in the browser
    ws.on(
        'message',
        handleMessage
    );

    handleMessage(e){
        var message=new Message;
        message.load(e.data);

        console.log(message.type, message.data);
    }

Sending a Message Object via WebSocket

    //works for browser natively AND node natively
    import { default as Message } from './node_modules/js-message/Message.js';
    //works for browser transpiled AND node natively
    import { default as Message } from 'js-message';

    //client example, but works the same on server too!
    var ws=new WebSocket('ws://myawesomeWS:8000');

    var myMessage=new Message;
    myMessage.type='setUsername';
    myMessage.data.username='sideshow bob';

    ws.send(myMessage.JSON);
