    I have started a new series at webup.org/blog called React Patters. It is intended to cover non-trivial component patterns in React.

    Here is the first post React Patterns: A Component with Unknown Content Variants

    Hi everyone, I want to announce that the xlsx-renderer v2.4.0 has been released.
    That introduce 2 new features that kick the functionality off :) Give it a review, we are very, very curious what do you think about our library ;)
    In React hooks, is there a way to call api and do calculations before rendering the chart?. It happens only after render, any thoughts on this?

    Hey everyone, I made a startup landing page template. Let me know what you think? Github: https://github.com/jkytoela/next-startd / Live: https://next-startd.vercel.app/

    @5P4RK3R make your chart component render only when data is fetched successfully
    use conditional rendering, like isSuccess && <Chart />
    If you prefer to not render your entire page (Imo is bad for user experience), just level up to your entire component isSuccess ? <Page /> : null
    Guilherme Samuel
    In these examples isSuccess is a state value that's set as true when your fetch is successful

    Hi Everyone,

    Error: Couldn't find a style target. How to fix it?

    I had a CSR app and now implemented Server-Side Rendering (SSR) with React, and get this error

    Error: Couldn't find a style target. This probably means that the value for the 'insert' parameter is invalid

    Get this error when I run the server and try to access the page.
    Tech sack in use: nodejs, reactjs, antdesign, babel and webpack.
    I already tried a lot of solutions from StackOverflow and other sources, nothing helped! Please, help me to solve it.

    Thank you!

    Hey There,
    I have been trying to run my react application on a subdirectory .
    I am using a load balancer (ALB) to and redirecting my application on "directory" from "https://mydomain/directory".
    But static file of the build was not being found by my application

    1. added direcctory on package.json. "homepage": "/directory"
    2. added basename on react-router-dom

    in my networks index.html is looking for ".#####/directory/static/js" and css in the same way

    i am only able to run my react build by redirecting static request to my react build, but this is not the good solution because i want to run 3 applications on my ALB and this will cause me change my assets folder name manually in the build, obviously don't want to do that.
    I have been applying multiple solutions but couldn't find a proper solution please someone help in this.😑

    Hey All,

    Hi there, I'm newbie here and React.js. Recently I implemented NES emulator on TypeScript/React.js. Please check it out! (Still WIP and some codes are still messy though)

    Hi good morning, I would like to have some feedback about this https://github.com/Markcial/inducer
    Is it already done elsewhere? Is there something that can be done better?
    Can I get the TS compiler to be able to type hint the actions?
    Can i have a partial shape for the state but not making it all optional?


    Hello, I am new with React and I face some issues. After I add onClick attribute to execute function it does not execute. Maybe anyone can advise me why it is so ?

    Hi everyone!
    To learn hooks, I wrote a Carousel component with support for touch, mouse dragging, lazy loading, pinch to zoom, thumbnails, modal and keyboard navigation.
    The source code is at https://github.com/yifaneye/react-gallery-carousel.
    The live demo is at https://yifanai.com/rgc.
    I would love to hear your feedback and recommendations! :)
    Thank you in advance!

    The most complete javascript cheat sheet and resource compilation you can find online!
    I didn’t get far, but that cheat sheet has bad info. Scoping is not determined by the keyword constructor; var, let, and const can all be globally defined as well as block-scoped. The context in where they are defined is pertinent to their characteristics.

    Thx for your feedback, I modifed that, even if I'm not completly sure that's wrong.

    but that cheat sheet has bad info
    You know, it took me 8 hours to write, so obviously let me know what other I can improve...


    Nice work. Keep it up. I’d recommend using MDN as opposed to W3Schools. Also, the for-loop, instead of statements labeling what those statements are (control/setup, condition expression, iteration/stepwise expression).

    How to pass a geojson object with setState
    I have a message Error: Objects are not valid as a React child (found: object with keys {type, coordinates}). If you meant to render a collection of children, use an array instead.
    How can I fix it
    Hello guys.. I have a pretty niche question I feel like for CRA development.
    I use the proxy feature of CRA to point to a domain, however, the IP attached to the domain changed, forcing me to change DNS. I know DNS takes a while to propagate, however, I know for a fact everything is propagated correctly because the website now works correctly everywhere, except when using it with the CRA proxy.
    I'm just curious if anyone knows of a way to reset http cache within NPM (or wherever this is stored, because I'm not entirely sure).
