preact v10.2.0 Release Notes

Release Date: 2020-01-07 // over 4 years ago

  • 🚀 Happy belated New Years to everybody 🎉 We hope you enjoyed the holidays and had some time off to recharge 👍 Our very first release in 2020 brings two new features and the usual round of bug fixes 💯

    🆕 New useErrorBoundary hook

    👀 There is a new hook called useErrorBoundary which allows you to catch errors that are thrown by any child components. It's essentially the hook version of componentDidCatch.

    // 1. parameter is null or the error that was caught// 2. paremeter can be called to reset the stateconst [err, reset] = useErrorBoundary();// Optional: You can pass a callback function that will// be executed when an error occurs:const [err] = useErrorBoundary(() =\> callMeMaybe());

    Usage example:

    // Example component that will throw an error on renderconst SomeComponent = () =\> { throw new Error("fail"); };const App = props =\> { const [err] = useErrorBoundary(); if (err) { return \<p\>Something went wrong...\</p\>; } else { return \<SomeComponent /\>; } };

    0️⃣ Lazy works with non-default export

    0️⃣ This PR was one of the smallest ones, but something that makes working with different kind of lazy loaded modules a lot easier. Previously lazy would always use the default export of the imported module. With this change it's now possible to use it with any export.

    // Look ma, no default exportconst LazyFoo = lazy(() =\> import("./Foo").MyComponent);

    🍱 On top of that we have the usual round of bug fixes. We'd like to thank everyone who reported them and helped us make Preact even better. Thank you so much!! 👍
