ANSI escape codes for manipulating the terminal

Package Exports

  • ansi-escape
  • ansi-escape/lib/colors
  • ansi-escape/lib/escapes

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ansi-escape) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Usage

var csi = require('ansi-escape')

console.log('1'.repeat(8))
console.log(
  csi
    // underline text
    .underline

    // red text
    .red

    // move cursor one line up
    .cursorUp

    // move cursor 2 cells forward
    .cursorForward(2)

    // the text to be escaped
    .escape('2'.repeat(4))
)
