Sometimes you need to temporarily disable CSS transitions. For example, when you want to change light/dark color-schemes and don't want a flashy transition.

That's why I created the withoutTransition method. This method has the following features:

Temporarily disable CSS transitions for the duration of the function call
Utilizes several methods choosing the best one based on the clients browser

Method Definition

let timeoutAction;
let timeoutEnable;
 
// Perform a task without any css transitions
export const withoutTransition = (action: () => any) => {
  // Clear fallback timeouts
  clearTimeout(timeoutAction);
  clearTimeout(timeoutEnable);
 
  // Create style element to disable transitions
  const style = document.createElement("style");
  const css = document.createTextNode(`* {
     -webkit-transition: none !important;
     -moz-transition: none !important;
     -o-transition: none !important;
     -ms-transition: none !important;
     transition: none !important;
  }`);
  style.appendChild(css);
 
  // Functions to insert and remove style element
  const disable = () => document.head.appendChild(style);
  const enable = () => document.head.removeChild(style);
 
  // Best method, getComputedStyle forces browser to repaint
  if (typeof window.getComputedStyle !== "undefined") {
    disable();
    action();
    window.getComputedStyle(style).opacity;
    enable();
    return;
  }
 
  // Better method, requestAnimationFrame processes function before next repaint
  if (typeof window.requestAnimationFrame !== "undefined") {
    disable();
    action();
    window.requestAnimationFrame(enable);
    return;
  }
 
  // Fallback
  disable();
  timeoutAction = setTimeout(() => {
    action();
    timeoutEnable = setTimeout(enable, 120);
  }, 120);
};

Method Usage

withoutTransition(() => {
  /* Your code here... */
});

You can see a full example of this method in action inside my article about disabling CSS transitions when changing color-schemes
