    Hi all. About the form validation section of the react book (around page 210-220) does anyone know why we need a value state in the Field Component? I read a blog post on the React homepage and it says getDerivedStatesFromProps() should be used very rarely, if not at all. So why do we need a state there when a prop could work just as good?
    Where can I upgrade my book to the latest version? Because mine says Revision 36 - Supports React 16.3.0 (2018-04-02)
    In the first chapter for the voting app, I don’t see any code that imports the actual data from the seed file? Am I missing something?

    @TazzyG Hi Laurie, did you ever manage to solve your problem regarding "trouble with the components cookbook app, starting on page 169." It seems I have had it for a couple days already and I run out of all ideas... I tried with different node.js versions, node-gyp versions etc. No success.

    My problem on mac when running $ npm start from components-cookbook/ (book r39):
    Failed to compile. ./node_modules/react-styleguidist/lib/index.js Module build failed: Error: ENOENT: no such file or directory, scandir '/Users/maciej.gulak/projects/fullstack-react-code/advanced-components/components-cookbook/src/components/theme/node_modules/asn1.md/lib' at Array.map (<anonymous>) at Array.map (<anonymous>)
    Any ideas how to fix it?
    Generally, when I run $ npm run install-allI get lots of node-gyp error regarding fsevents..
    Maciej Gulak

    @gvlax OK, solved. Generally the issue is caused by react-scripts module that requires obsolete fsevents
    (after running $ npm i in the components-cookbook/ you can use a command $ npm ls fsevents to see its dependencies)

    Probably you can just update react-scripts OR do what I did to the components-cookbook/package.json file:
    I added there:

      "resolutions": {
        "fsevents": "1.2.9"

    (more about resolutions...)[https://github.com/rogeriochaves/npm-force-resolutions]

    then from a command line in components-cookbook/:

    $ npm i node-pre-gyp -D
    $ npm ls fsevents
    $ npx npm-force-resolutions
    $ npm ls fsevents
    $ npm start
    How to get the correct focuse for voice over in ios while navigating into new screen using stack navigator in react native ?

    It seems this place is dead. Everyone must have moved to Vue.js already ... :-/

    I first thought, "What became of react-native Navigator SceneConfigs?", when looking at URL at bottom of p742. http://facebook.github.io/react-native/releases/0.31/docs/navigator.html#configurescene It doesn't work. Tracked this down eventually as this:
    https://archive.reactnative.dev/docs/0.31/navigator#configurescene Why no redirects.. seems to be the correct .
    Navigator appeared under Components then. Couldn't find it now in (0.63).
    Then I saw this:
    react-navigation/react-navigation#1328 entitled Navigator is deprecated in RN 0.44.0 referring to this: https://reactnative.dev/docs/navigation
    But the issues thread is more useful.
    Why is there no errata content? There are tons of bad links in the book like this.
    Is the book no longer being maintained/updated?

    Hi Everyone
    I have recently started working in react & created application using react as front end. Can anyone suggest what can be used as backend to store data variables & files at cloud?
    2 replies
    I recommend Spring Boot.
    Sneh Malhotra
    I have already developed the frontend app now working for backend hence seeking advise. I coded for JSON server but is it good to have as a backend or something else?
    Or shall I go for MySQL or DynamoDb or MongoDB or Node js?
