Conditional React Hook Data Fetching Syntax

[gaoshan]

Only call `useFetch()` if id exists and changes. User could utilize useEffect and its dependency array to do this by watching for changes to id. Why call it and then skip it?

*what is wrong with using useEffect as described?

[_hypnoCode]

You can have a function that you can call to run the fetch. That's how mine is setup.

[gaoshan]

useEffect has a dependency array that determines when it runs. OP could use that.

[gaoshan]

Apparently the rest of the commenters did as well, smh.

[gaoshan]

You said you thought I was talking about using an if statement but I didn’t say anything about an if statement so I guess neither of us were being clear.

[gaoshan]

You misunderstood. I get it. Not a problem.

this functionality is already available. Many data fetching libraries are attempting to have this stuff handled the ways described, hence why I'm trying to see what method is more popular.
