Convert between keyboard keycodes and keynames and vice versa.


Simple map of keyboard codes.

$ component install timoxley/keycode
var keycode = require('keycode');
document.addEventListener('keydown', function(e) {
  console.log("You pressed", keycode(e))

keycode tries to make an intelligent guess as to what you're trying to discover based on the type of argument you supply.


Returns the name of the key associated with this event.

document.body.addEventListener('keyup', function(e) {
  console.log(keycode(e)) // prints name of key 

Due to the keypress event being weird,keycodecurrently does not support the keypress event, but this should not be an issue as keydown and keyup work perfectly fine.


Returns the lowercase name of a given numeric keycode.

keycode(13) // => 'enter' 


Returns the numeric keycode for given key name.

keycode('Enter') // => 13 
// keycode is not case sensitive 
keycode('eNtEr') // => 13 

Common aliases are also supplied:

> for (var alias in keycode.aliases) { console.log(alias, keycode(keycode(alias))) }
ctl ctrl
pause pause/break
break pause/break
caps caps lock
escape esc
pgup page up
pgdn page up
ins insert
del delete
spc space

Key code/name maps are available directly as and keycode.names respectively.

keycode.names[13] // => 'enter'['Enter'] // => 13
