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
});
