See https://github.com/mharju/vim-fiddle for a similar project (but I believe Mac only).

• Selenium
• Vim with python 2 support (check with :python print "hello")
• The selenium Python driver (included)
• For jslint integration, a working jslint command (on my system, I use node.js + npm install jslint -g)
• A web server to host the fiddles (for instance apache)

• A "fiddle" consists of a index.html file and a code.js file
• When either file is saved, vimfiddler refreshes the browser (via selenium)
• jslint integration, hit F4 to jslint the current file.

• Unpack vimfiddler in ~/public_html (or use a symbolic link)
• You need Selenium Server from http://seleniumhq/download/
• On my system, the command selenium starts the selenium server. If your system is different, edit fiddler.vim
• On my system, the command jslint starts jslint, if your system is different, edit fiddler.vim.
• Edit fiddler.vim to use a different browser. The default is *firefox. Use *googlechrome to use Chrome.

• Start vim

• In Vim:

  :source fiddler.vim
  :StartSeleniumServer
  :StartSeleniumClient
  :OpenFiddle example
  
  or
  
  :NewFiddle
  Name: <enter fiddle name>
  Use template: default

• When either code.js or index.html is saved, Vim will tell selenium to refresh the page.
