  • Let me critique your site's FE perf
    5 projects | | 21 Jan 2022
    Your JS bundle size is really inflated because of React, I suspect you could move to Preact and drastically reduce your overall JS package. I haven't done this with Next.js before, but it looks like there is some good reading out there on the subject.
  • Why you have to use className in React, but not in Preact?

  • Preact Async Rendering
    2 projects | | 5 Jan 2022
    Bear in mind that this is still under review by the Preact team but if you need it desperately like us, feel free try out the preact-async package on npm. I'm hoping that Preact team will accept this change and get it into the main package.

  • Vala reactive programming
    2 projects | | 6 Dec 2021
    I've been doing some web programming using preact these last weeks and one of the things that impressed the most was the way logic and UI are split in code. When doing functional components this is specially explicit. Your function returns whatever should be displayed by the component and receives a props object containing all the information the components need to render. A component rerenders when some of its props are changed, either because an external component made changes or in response to an event.

    Preact is a "Fast 3kB alternative to React with the same modern API". It's smaller than React but shares most of it's features (Hooks, Context), so you can write normal React code but benefit from better performance.
  • Don't Optimize Your React App, Use Preact Instead
    4 projects | | 1 Nov 2021
    A few months ago, I wrote an article based on optimizing react loading time, and most of the reader's comments were to try Preact to get default optimization. So I decided to try preact with the same app used for the previous article. Let's first get an intro about Preact.
