normalize-time

normalizer for time values, given a start time and duration

normalize-time

This is a normalizer for time-based stuff. The module is a function that takes 4 arguments:

  • start time
  • duration
  • min
  • max

min and max are optional, and wil default to 0 and 1 respectively.

It returns a function that takes a single param, time

npm install normalize-time
var tnorm = require('normalize-time');
var time = new Date().getTime();
var duration = 3000;
 
var normalize = tnorm(time, duration)
 
for(var t = time; t < time + duration){
    console.log(normalize(t));
    t = new Date().getTime();
}

What we have done here is created a function that will normalize 3 seconds of time to values between zero and one. We could have passed min and max values to normalize between any two values.
