Hi guys, can we type the variable ? Like php : public bool isTrue. Doing the same with shouldShowHeart : const bool shouldShowHeart ?

Hey Micka,

Unfortunately, you can't. See syntax of "const" statement: https://developer.mozilla.o... - it just "%name% = %value%". We're talking about simple variables here with "const"... in your PHP example you're talking about class properties :) And fairly speaking you don't need to typehint "const" because you can set its value only once. If you need a bool const - set a bool value and that's it. You will be 100% sure it's bool further in the code as you can't re-set it because it's a constant.

Cheers!

Hey guys!

So we can pass a prop from rep_log_react.js to RepLogApp, but what's the right way to pass that prop from our twig template to rep_log_react.js?

I did it with this in my controller:


        return $this->render('lift/index.html.twig', array(
            'leaderboard' => $this->getLeaders($replogRepo, $userRepo),
            'shouldShowHeart' => true,
        ));

This in my template:


        <div id="lift-stuff-app" data-should-show-heart={{shouldShowHeart}}></div>

And this in rep_log_react.js:


const shouldShowHeart = document.querySelector('#lift-stuff-app').dataset.shouldShowHeart;

render(
    <RepLogApp withHeart={shouldShowHeart}/>,
    document.getElementById('lift-stuff-app')
);

That works, but it doesn't look hipster enough to belong in the React world. Is there a better way?

Thanks!

Hey Dan_M!

but it doesn't look hipster enough to belong in the React world

Haha! Well done :). There are actually a bunch of different ways to do this - I was just having this conversation with several people this past week. We do talk about this WAY later in the tutorial - see https://symfonycasts.com/screencast/reactjs/server-pass-props and the chapter before it (for a bit of the setup).

In that chapter, we simply set a global variable. But, other options include - setting data- attributes (like you've done) and creating a special <script type="text/json" id="my-original-data"> and then reading and decoding that JSON. That last one actually came out as the "subtle" winner from my talks this pas week... though they are all approximately the same as far as security goes, etc.

So, long way of saying - your way isn't so un-hipster actually ;). Though you can (and we show this in that other chapter) do some cool stuff where you use the ...spread operator so that you don't need to grab each piece of data and manually do the attribute={var} way of setting things.

Cheers!
