Advanced ANSI formatting tool for Node.js
ansi.js is a module for Node.js that provides an easy-to-use API for
writing ANSI escape codes to
Stream instances. ANSI escape codes are used to do
fancy things in a terminal window, like render text in colors, delete characters,
lines, the entire window, or hide and show the cursor, and lots more!
$ npm install ansi
var ansi =cursor =// You can chain your calls forever:cursor// Set font color to redbg // Set background color to grey// Write 'Hello World!' to stdoutbg // Reset the bgcolor before writing the trailing \n,// to avoid Terminal glitches// And a final \n to wrap things up// Rendering modes are persistent:cursor// You can use the regular logging functions, text will be green:console// To reset just the foreground color:cursorfgconsole// to go to a location (x,y) on the console// note: 1-indexed, not 0-indexed:cursor// to clear the current line:cursor// to go to a different column on the current line:cursor// Clean up after yourself!cursor
