Browserslist-rs now uses static data to reduce binary size by over 1MB, improving memory use and performance for Rust-based frontend tools.
Get async animation frame context
npm install --save async-raf
When you want to get a value from requestAnimationFrame, instead of:
const area = await new Promise((resolve) => {
window.requestAnimationFrame(() => {
const { offsetWidth, offsetHeight } = someElement;
resolve(offsetWidth * offsetHeight);
});
});
You can use AsynRAF:
const area = await asyncRaf(() => {
const { offsetWidth, offsetHeight } = someElement;
return offsetWidth * offsetHeight;
});
// All callbacks will be execute inside `requestAnimationFrame()`
asyncRaf(() => {
// get some properties that causes page reflow
const { offsetWidth, offsetHeight } = someElement;
// return a value to be resolved.
return offsetWidth * offsetHeight;
});
// OR resolve it yourself
asyncRaf((resolve) => {
// get some properties that causes page reflow
const { offsetWidth, offsetHeight } = someElement;
// resolve the value.
resolve(offsetWidth * offsetHeight);
});
// OR use async callback
asyncRaf(async () => {
// get some properties that causes page reflow
const { offsetWidth, offsetHeight } = someElement;
const area = await calculateElementArea(offsetWidth, offsetHeight);
return area;
});
