bcat

node-bcat

Pipe to browser utility, this is (sort of a) a bcat clone in javascript. Very useful for log tail fun :)

node-bcat features auto scrolling (with enable/disable), ansi to html coloring (--ansi) and behavior and color customization.

This module uses RC to manage its configuration, so in addition to command line arguments you may save your favorite configuration in .bcatrc. Also, you should take a look at scat which pipes javascript into your browser or hcat that pipes html into your browser.
