Common middleware practices

Delay update loading

When the response is very fast, the loading status will flash once, which will bring a bad experience to the user. Delaying the loading update can make the loading status display after a period of time. If the response is completed within this period, it will not appear. Loading status. Let's implement a middleware with delayed update loading.

const delayLoadingMiddleware =
(delayTimer = 1000) =>
async (ctx, next) => {
//Control loading by yourself
ctx.controlLoading();

//Delay updates for a specific time
const timer = setTimeout(() => {
ctx.update({ loading: true });
}, delayTimer);
await next();
ctx.update({ loading: false });
clearTimeout(timer);
};

useRequest(methodInstance, {
middleware: delayLoadingMiddleware()
});
