现在 src/loading.tsx
可以统一定义全局所有页面级别在懒加载时的 loading 动画,如果你需要每个页面不同的话,在这里面判断一下吧。
比如:
// .umirc.ts
routes: [
{ path: '/docs', component: 'docs', loading: 'A' },
]
// src/loading.tsx
import { ReactNode } from 'react'
import { useRouteProps } from 'umi'
const map: Record<string, ReactNode> = {
A: <div>A loading</div>, // or import a component, don't use async import
}
export default function Loading() {
const props = useRouteProps()
const fallback = (
<div>fallback loading</div>
)
if (props?.loading) {
return map[props.loading] || fallback
}
return fallback
}
你提到的在每个页面下新增 loading.tsx
文件来预加载,现在约定式路由里每个文件都会被视为一个路由路径,添加 loading.tsx
就变成 /loading
的路由了,所以这种方式是做不到的,比如 nextjs 也只能在 app dir 而不是 pages dir 去新增各种约定文件的设定。
另外现在绝大多数用户使用的是配置式路由,自己根据配置调整下或者根据 location.path
判断下条件渲染吧。
