QUESTION
I have a component like the following:
...ANSWER
Answered 2021-Nov-12 at 10:34I suggest that you create a condtional wrapper component which takes data, error and loading as props in some form. It will check these values and return the children if data should be displayed.
This is how you would use it in any component:
QUESTION
I hope someone can shed light on this. Using the react Route component gave me this idea and I can't figure it out
The React component seems to render the children, but it also returns variables such as match. Here's an example of what I'm talking about:

I'll take a counter example to show you how you could do that:
QUESTION
I am trying to understand 'render props' in the official React tutorial. There I came across this:
...ANSWER
Answered 2021-Aug-05 at 06:58You must first understand why people came up with render props. Sometimes you want to create some reusable functionality, without any UI. There is no direct way to do this in react, because normally the components render something. So how do we create a component which renders nothing but still gives you some functionality? Here is an example of very simple render props:
QUESTION
Can someone explain in a bit more detailed way why using Render Props with React.PureComponent will generate a new value for the render prop in each render?
docs link: https://reactjs.org/docs/render-props.html#use-render-props-for-cross-cutting-concerns
...ANSWER
Answered 2021-May-07 at 20:27Because when React renders -> mouse => () is going to be a new reference every render.
The fix by placing inside another function renderTheCat, it's going to be the same.
Anther way of thinking of it (()=>{}) === (()=>{}) will always equal false. Were as renderTheCat === renderTheCat equals true.
QUESTION
I have a React component that should subscribe to a React Context and render some text. When the context updates the text should update, but when this update occurs I want to animate the component out with the old value and animate it in with the new value. I'm new to React Spring but figured that Transition in their Render-props API would do the trick here to fire animation events on mount and unmount respectively.
The From, Enter and Leave seem to work and the animations do play when the context changes, however it will change the contents of the context first, then render "Enter -> Leave" of the old element simultaneously as it renders "From -> Enter" on the new element, resulting in duplicated elements and incorrect text rendered when the "old element" is leaving.
My mind is telling me I need to make better use of lifetime-cycles to handle the duplicated elements and perhaps abstract the context value using props from the parent component rather than using the context value directly, but I could be dead wrong here.
So, my question is how do I get the Leave animation to play with the old text value and then play the Enter animation with the new text value and only have one element shown at a time?
Also, this is my first question here, so please let me know if I'm doing this wrong.

Answered 2020-Dec-10 at 09:28Bounced ideas solutions with a friend and we found a solution (mostly he found the solution to be honest).
Firstly, the rendering of correct data was a simple oversight by me, so instead of using data directly from context, we actually use the data we pass to the transition API.
QUESTION
I have a simple react component....
...ANSWER
Answered 2020-Aug-10 at 13:39A real react component needs to be a function or a class. You do not need to pass props for it to be a component.
The top example you gave is just a variable with some jsx inside, not a real component.

QUESTION
I'm using react-spring with the render-props API to set a background-size CSS property. The change is triggered whenever the background image changes. The thing is: the background image does not always load fast enough for the background size to change flawlessly.
Is there a way to delay the Spring until the background image is loaded, or do I have to preload all my background images beforehand?
There is a lot of background images that can be set to my object and they are quite large in size, so preloading them might take a lot of space in memory so it's not optimal in my case.
Here is my code:
...ANSWER
Answered 2020-Feb-13 at 13:11I have an idea you might use here. For img components there is a onLoad event handler. If you display an image with the same src hidden somewhere on the page. Then you can set a state when the image is finally loaded.
Then use this state to change the to property of the Spring component. Something like this:
