node-bcat

Pipe to the browser utility, 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.

example

> npm install -g bcat

> cat somefile | bcat

// redirect error stream also
> node index.js 2>&1 | bcat

Want to see something moving too?

test.js:

setInterval(function () {
	console.log(1)
}, 1000)
