Getting Started

The Javascript streaming client is a library that contains all the necessary dependencies to run not only in the browser, but also in Node.js environments.

Browser Usage

To use the library in your browser project simply include the library file in your HTML page as a script.

Node.js Usage

Since the window object is not available in Node.js, it will need to be mocked before we import the library.

1. Mock the window object before importing the library:

   if (typeof global.window === 'undefined') {
      var window = {
      navigator: { userAgent: "atmosphere.js" },
      document: {},
      location: {
      protocol: 'https:'},
      JSON: JSON
      };
      
      window.WebSocket = require("ws");
      window.EventSource = require("eventsource");
      window.XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
      
      global.window = window;
      global.location = window.location;
      global.WebSocket = window.WebSocket;
      global.EventSource = window.EventSource;
      global.navigator = window.navigator;
      global.document = window.document;
   }
   

2. Then import the library with require syntax:

   var Streamer = require("<path to the library>");

3. The library is ready for use in your Node.js project.
