UmiJS

# Load on demand

For performance reasons, we load modules and components on demand.

# Loading Components on Demand

Implemented through the umi/dynamic interface, such as:

import dynamic from 'umi/dynamic';

const delay = (timeout) => new Promise(resolve => setTimeout(resolve, timeout));
const App = dynamic({
  loader: async function() {
    await delay(/* 1s */1000);
    return () => <div>I will render after 1s</div>;
  },
});

# Loading Modules on Demand

Implemented by import(), such as:

import('g2').then(() => {
  // do something with g2
});
