Nice!!!

I have used this technique for 2 past React projects before ✌️✌️✌️

I used a global hook state manager that I created (github.com/devhammed/use-global-hook) then renders my custom Material UI Dialog component near routes in App.js then all I have to do is to call the showModal action (I use React.useReducer) whenever I need to:

showModal({
  title: "Hello",
  content: (<Typography>Hi</Typography>),
  actions: [] // buttons
})

Cool!

Cool, can you share some examples for your implementation?

Hammed Oyedele • Sep 17 '20

The implementation is almost the same with the one in this post but I used use-global-hook instead of context (though it uses context under the hood too).

Hi there! Nice solution. It throws an error when you click in either cancelo or accept button of the dialog...

Auto answering this.... changing this line solves the problem.

<DialogTitle id="alert-dialog-title">{title ? title : ""}</DialogTitle>

This is actually a really cool way to handle confirmations. The only minor problem is, when you press "agree" or "cancel", dialog content disappears just before the exit animation of the dialog completes. It creates some sort of a flickering effect. You need to watch carefully to see it, but if your exit animation duration is higher, you will end up with an empty dialog slowly fading away :)

Other than that, real cool way for confirmations and simple info dialogs!

So here is the fix of "flickering" effect which was caused by resetting the state before dialog is faded out.

Taras Dymkar • Jun 10 '20

Yeah, I'm not sure but looks like to solve this issue you need to reset confirmationState on material-ui`s Dialog onExited callback. And on close/submit just set "open" prop to false.

I know it's a bit late but thanks for the post, I found it really helpful! I was wondering whether or not using this service across multiple components would trigger a rerender for any component using the context any time a component called the confirm function and it seemed like it did. I added a useCallback around the openConfirmation declaration (with a setConfirmationState dependency) and it seemed to do the trick. Can anyone verify that this is the right way to go about this?

Thanks, clear and concise. I’d like to try this.

I literally just made an account to say you're incredible, and your tutorial is flawless. Thank you <3

Hello! If I try to nest the children props inside the Provider instead of passing it as a prop it return a TypeError: PromiseReject called on non-object. Anyone have an idea why??

Tabrez Basha • Sep 17 '20

Is it possible to dynamically change the content of the dialog?
Example sandbox (will be ugly, but just for an example): codesandbox.io/s/neat-dialogs-fork...

Basically, I would like to know if this kind of API would suit for a proper Modal.
