Kurento JavaScript Tutorial

Kurento Client JavaScript demos

This project contains a set of simple applications built with JavaScript Kurento Client APIs (kurento-client-js and kurento-utils-js).

The source code of this project can be cloned from the GitHub repository.

Installation instructions

Be sure to have installed Node.js in your system:

curl -sL https://deb.nodesource.com/setup | sudo bash -
sudo apt-get install -y nodejs

Also be sure to have installed Bower in your system:

sudo npm install -g bower

Each demo is located in a single folder (e.g. kurento-hello-world, kurento-magic-mirror, and so on). For example, to launch the kurento-hello-world demo, run:

cd kurento-hello-world
bower install

An HTTP server is required for these demos. A very simple way of doing this is by means of a NodeJS server. This server can be installed as follows:

sudo npm install -g http-server

Then, in each demo folder execute this command:

http-server

Finally, open this URL in your browser: http://localhost:8080/

Take into account that demos with Generators (kurento-faceoverlay-generator, kurento-recorder-filter-generator, and so on) require co (generator based flow-control for nodejs). In these demos, the experimental JavaScript support must be enabled. In Chrome, this can done in this configuration page:

chrome://flags/#enable-javascript-harmony

After enabling this flag, you'll need to restart your browser.

Optional parameters

The demos accept some optional GET parameters given on the URL, you only need to add them to the query string in the same way you would add them to the Node.js executable on your command line:

http://example.com/index.html?ws_url=ws://example.org/kurento

All the demos accept the ws_url parameter to set the WebSocket Kurento MediaServer endpoint, other parameters specific to each demo can be found at the top of their index.js files.
