I have the following logic inside a react component where, I am rendering different component based on the boolean values. This peace of code is very difficult to understand. Are there anyways, I can simply that logic:
{isEnabled ? (
<>
{!loading ? (
<>
{items.length === 0 ? (
<>
<ComponentOne/>
<Container>
<img src={Image} alt="Image" />
</Container>
</>
) : (
<ComponentTwo/>
)}
</>
) : (
<div>
<LoadingComponent/>
</div>
)}
</>
) : (
<ComponentThree/>
)}
I'd probably split it up into seperate components and pass parameters down the component tree for example
{isEnabled ? <IsLoadingComponent loading={loading} items={items}> : <ComponentThree/>}
You might find it useful to split the component up into a "Loading" version and a "Loaded" version so you don't have to handle both states in the same component. Then the component basically just renders the "Loading" or "Loaded" version depending on the flag.
But even without that, you can at least make that easier to debug by using if/else if etc. and assigning to a temporary variable:
let comp;
if (isEnabled) {
if (loading) {
comp = <div>
<LoadingComponent/>
</div>;
} else if (items.length === 0) {
comp = <>
<ComponentOne/>
<Container>
<img src={Image} alt="Image" />
</Container>
</>;
} else {
comp = <ComponentTwo />;
}
} else {
comp = <ComponentThree />;
}
Then just
{comp}
where that nested conditional was.
I think you are making a simple thing very complicated. What we can do instead is that make use of "&&".
{ isEnabled && loading && <LoaderComponent /> }
{isEnabled && !items.length &&
<>
<ComponentOne/>
<Container>
<img src={Image} alt="Image" />
</Container>
</>
}
{isEnabled && items.length && <ComponentTwo/>}
{!isEnabled && <ComponentThree />}
