I wasn't sure on a title for this issue, but I can better explain it here. I have a custom hook that is relying on some information. Part of the information must rely on an async call.
I have three situations happening.
- Tried conditionally rendering the custom hook, but react does not like that due to rendering more hooks on a different render.
- The custom hook is only mounting once and not passing in the updated information it needs.
- I tried passing the dependency to the custom hook and it causes an infinite loop.
Here is a small example of what I'm doing.
Custom Hook:
export function useProducts(options){
const [products, setProducts] = useContext(MyContext)
useEffect(() => {
// only gets called once with `options.asyncValue` === null
// needs to be recalled once the new value is passed in
const loadProducts = async () => {
const data = await asyncProductReq(options)
setProducts(data)
}
loadProducts()
}, []) // if I pass options here it causes the infinite loop
return [products, setProducts]
}
Inside function calling:
export function(props){
const [asyncValue, setValue] = useState(null)
useEffect(() => {
const loadValue = async () => {
const data = await asyncFunc()
setValue(data)
}
loadValue()
}, []}
const options = {...staticValues, asyncValue}
const [products] = useProducts(options)
return (
<h2>Hello</h2>
)
}
I know that I need to pass the options to be a dependency, but I can't figure out why it's causing an infinite reload if the object isn't changing once the async call has been made inside the func.
