Tiny function to invoke a callback after the browser renders the next frame

Table of Contents


This project uses node and npm. Go check them out if you don't have them locally installed.

$ npm install --save afterframe
+ afterframe@0.0.0

Then with a module bundler like rollup or webpack, use as you would anything else:

// using ES6 modules
import afterFrame from "afterframe";

// using CommonJS modules
var afterFrame = require("afterframe");

The UMD build is also available on unpkg:

<script src=""></script>

You can find the function on window.afterFrame.


Inspired by Nolan Lawson's blog on measuring layout

import afterFrame from "afterframe";


// Do some work...

afterFrame(() => {

afterFrame currently relies on requestAnimationFrame and MessageChannel so support starts at IE10 and above.

Examples & Demos

Sample CodePen demonstrating usage of afterFrame

Example function wrapping afterFrame in a Promise:

let promise = null;
function afterFrameAsync() {
  if (promise === null) {
    promise = new Promise((resolve) =>
      afterFrame((time) => {
        promise = null;

  return promise;



Invoke the given callback after the browser renders the next frame


  • callback Function The function to invoke after the browser renders the next frame. The callback function is passed one argument, a DOMHighResTimeStamp similar to the one returned by, indicating the point in time when afterFrame() starts to execute callback functions.
