Very lightweight (0.39kb minified and gzipped), no dependencies Countdown Timer that provides a simple API to get various time formats

npm install countdown-js

or clone directly from this repository

See the demo file for an example.

Create an index.js file

var Countdown = require('countdown-js')

// setup end datetime for timer
var ten_days = 1000 * 60 * 60 * 24 * 10
var end = new Date(new Date().getTime() + ten_days)

var timer = Countdown.timer(end, function(timeLeft) {
  console.log(timeLeft)
  console.log(timeLeft.days)
  console.log(timeLeft.hours)
  console.log(timeLeft.minutes)
  console.log(timeLeft.seconds)
}, function() {
  console.log("Countdown Finished!")
})

Run uglify-js to minify your file and browserify on your index.js so it can be run in the browser

npm install -g uglify-js browserify
uglifyjs ./index.js -o index.min.js -c -m | browserify -g uglifyify ./index.min.js > bundle.js

Include your bundle.js in your code right before the closing </body> tag so it doesn't need to wait for DOM.ready signal.

<script src="./bundle.js"></script>

Fork the repository and clone it

Set up the development environment

npm install

After making changes run the following from the root countdown.js folder to test the demo and ensure it still works

uglifyjs ./index.js -o dist/countdown.min.js -c -m | browserify -g uglifyify demo/js/index.js > demo/js/bundle.js

Make any changes, update test/*.js files as appropriate.

Before committing run npm run test to ensure all tests pass
