sister ANSI

Ansi escape codes faster than you can say "Bam bam".

Installation

npm install sisteransi

Usage

const ansi = require('sisteransi');
// or const { cursor } = require('sisteransi');

const p = str => process.stdout.write(str);

// move cursor to 2, 1
p(ansi.cursor.to(2, 1));

// to up, one down
p(ansi.cursor.up(2)+ansi.cursor.down(1));

This is basically a slimmed down version of ansi-escapes. I've made a few minor tweaks and additions, for example the option to repeat more commands.
