Hi everyone!

This week, there is still a lot of content about signals, but it's the turn of Server Components to take over the discussions!

One week left to send your talk proposal to the CFP of React-Native-Connection (Paris - June 1st).

    WTF Is Code Extraction

    WTF Is Code Extraction

    MiΕ‘ko (Qwik) explains the advantages of co-locating server/client code in the same file and the limitations of the current Next.js model (export extraction): you can only declare one getServerSideProps function and you have to make use of ReturnType to inject the right data type into the client component. Function extraction and closure extraction offer a better developer experience.

    These techniques are not yet used in the React world today, but we can expect to see them appear in our frameworks soon. The Qwik team plans to decouple its code extraction from the framework. Tanner Linsley is collaborating with them and is already using this type of extraction on Bling, the toolkit that should power the upcoming TanStack Start framework.

    I think we can also include React Server Components in the category of techniques that allow to seamlessly mix server/client code: we should rather consider this solution when discussing the current limits of Next.js.

    React Server Components

    React Server Components

    After signals, it's the turn of Server Components to be in the spotlight this week. Dan Abramov triggered many discussions while looking for good mental models to explain the new feature. You'll have to dig into these discussions to find the analogies that speak to you the most.

    Server Components could also have unsuspected benefits: a communication layer for Electron threads or a flexible data-layer for static site generators.

      Surveyjs - Extensible JavaScript libraries for surveys and forms

      Extensible JavaScript libraries for surveys and forms

      SurveyJS is a set of open-source JavaScript form libraries that you can easily integrate into your web app. It lets you create and run multiple forms, retaining all sensitive data on your servers, or have your own self-hosted WYSIWYG form builder that non-tech users can use directly.

      You can also analyze survey results in custom-built dashboards, save your forms to PDF, or simply convert them to editable PDF files. It offers native support for React and Angular rendering and total freedom of choice as to the backend, because any server + database combination is fully compatible.
