Use morse code rhythm to awake something.
When a front-end project on production, there are functions that still need to be invisible — unless certain conditions were reached. We can call these functions as “experiment function”. In many ways, people use a switch or some keyword to turn these functions on, and Rhyke use its own idea — using morse code gesture rhythm.
Rhyke comes from “rhythm” and “awake”, which means “Awake something by rhythm”.
Inside RhykeJS, it listens mouse or touch events from the user defined area. By setting dashTime, it understands how long dose a click means “short signal” or “long signal”, and translates them into string . and - rhythm. Once the input rhythm matches the defined rhythm, something will be triggered.

yarn add rhyke
RhykeJS was built in umd, you can use it in different way:
- ES6 modules
import Rhyke from 'rhyke'- CommonJS
const Rhyke = require('rhyke')- Web broswer
<script src="rhyke.js"></script>
<script>
const Rhyke = window.Rhyke
</script>The Rhyke instance is a constructor, you must use new operator to get initialization.
const rhyke = new Rhyke({
el: 'body',
rhythm: '...---...',
matching (rhyArr) {
// get user input rhythm array
// such as [".", ".", "-", "-", "-", "."]
},
matched () {
// trigger when rhythm matched
},
unmatched () {
// trigger when rhythm unmatched
},
onTimeout () {
// trigger when timeout
}
})Rhyke accepts one object as its options:
defaultOptions = {
// morse code listening area
el: 'body',
// define your rhythm, use "." as dots and "-" as dashes
rhythm: '...',
// how long from "dot" to "dash"
dashTime: 400,
// timeout for resetting input
timeout: 2000,
// RhykeJS uses mouse event in default; once the page was in mobile mode,
// you should set `tabEvent` to `true`, then RhykeJS would use touch event in replace.
tabEvent: false,
// get user input rhythm array
matching: () => {},
// trigger when rhythm matched
matched: () => {},
// trigger when rhythm unmatched
unmatched: () => {},
// trigger when timeout
onTimeout: () => {}
}Once the matched or unmatched triggered, you may want to remove the event listener of the element you bind:
matched () {
// something was awoke
rhyke.removeListener()
}MIT
