preact-async-route

Deprecation notice

preact-x supports Lazy component, which can be used as shown here. Prefer using the Lazy component along with Suspense instead of this package.

This package is still useful for preact versions < 10

<AsyncRoute> provides similar props to return a lazily loaded component either as a Promise resolving to the component or return the component in a callback.

<AsyncRoute> also has a loading props, to which you can pass a component to be shown while the component is being lazily loaded.
