No installation necessary! SamsokJS runs completely in the browsser, and need only be deployed as is. It can even run directly from the file system without a server.
Server side proxy
There is a dependency on Cheerio which is used to be able to process HTML data with jQuery-like syntax even in web worker threads (where the browser DOM is unavailable). Because Cheerio is a NodeJS module, it must be run through Browserify in order to be used in this project. The following syntax can be used to regenerate the cheerio.browserified.js file:
browserify index.js --standalone cheerio > cheerio.browserified.js
Also, at the time of writing (Dec 8th 2014) the following bug had to be manually patched to get Cheerio to run in browserified mode: https://github.com/cheeriojs/cheerio/issues/549
After patching the bug the code should also be minified using any minification library.
