What options works best for you?

If you think the defaults does not work well for you, please post here to tell us which devices it doesn't work well, and also which settings does work well. Many thanks!

Options

All parameters are optional:

• sensitivity - Specifies the minimum value for wheelDelta for it to register as a valid scroll event. Because the tail of the curve has low wheelDelta values, this will stop them from registering as valid scroll events.

• delay - Threshold for the amount of time between mouse wheel events for them to be deemed separate.

• inertiaDecay - Inertia event may be no more than this percents smaller that previous event.

This is not working well for me. I tried with default and some custom settings, it is being registered multiple times instead of once when I scroll with trackpad on Macbook in Chrome. I tested the same with old library and there is no issue. Only one event is detected as it should. With your library, multiple events are detected.

I used this https://lethargy-ts.vercel.app/ to test again, and I can see blue dots on top of the curve and a few after that, and some at the end of the curve.

I tried a few settings but it makes scrolling super stutterish in Edge

It seems it detects a lot of false inertial positives

Defaults worked well for me on windows but I noticed for my particular project on Mac I had to increase the sensitivity. These values seemed to work great on the devices I tested on.

import UAParser from 'ua-parser-js'; let isMac = parser.getResult().os.name.toLowerCase() === 'mac os'; const Lethargy = require('exports-loader?type=commonjs&exports=single|this.Lethargy!lethargy/lethargy'); const lethargy = new Lethargy(isMac ? 7 : 1, 50, .2);
