delayRender() ​

ts

With delayRender you can make sure that the render waits until you are ready. This is useful for building page transitions.

Important ​

If you call delayRender you need to call ready/remove or the render will never happen

Example ​

js
import { onRequest } from 'crelte';
import { animate } from 'motion';

onRequest(async req => {
    if (req.origin !== 'click' && req.origin !== 'manual') return;

    const delay = req.delayRender();

    await animate(plane, { x: '0%' });

    // wait until the new page is ready to be rendered
    // if the render was cancelled we return
    if (await delay.ready()) return;

    await animate(plane, { x: '100%' });
});

Returns ​

DelayRender
