I use trpc to fetch this. But how do I prevent it from fetch at first mount and remove the loading state. I just want the loading to load when i start the input typing - without using my own defined isLoading state.

In mobx it would be very easy. Since you're using hooks, make it more or less like this:
import React, { useState } from "react";
import { api } from "../utils/api";

interface ResultPropsType {
input: string,
}

const Results = (props: ResultPropsType) => {
const searchSomething = api.surau.searhSomething;

const { data, isLoading } = searchSomething.useQuery({
name: props.input,
});

return (
{isLoading ? (
<div>Loading...</div>
) : (
<div>
{data?.map((item) => {
return (
<div key={item.id}>
<div>{item.name}</div>
</div>
);
})}
</div>
)}
);
};

const Test = () => {
const [input, setInput] = useState<string>("");

return (
<div>
<input type="text" onChange={(e) => setInput(e.target.value)} />
{ input.length > 0 ? <Results input={input} /> : null }
</div>
);
};

export default Test;
import React, { useState } from "react";
import { api } from "../utils/api";

interface ResultPropsType {
input: string,
}

const Results = (props: ResultPropsType) => {
const searchSomething = api.surau.searhSomething;

const { data, isLoading } = searchSomething.useQuery({
name: props.input,
});

return (
{isLoading ? (
<div>Loading...</div>
) : (
<div>
{data?.map((item) => {
return (
<div key={item.id}>
<div>{item.name}</div>
</div>
);
})}
</div>
)}
);
};

const Test = () => {
const [input, setInput] = useState<string>("");

return (
<div>
<input type="text" onChange={(e) => setInput(e.target.value)} />
{ input.length > 0 ? <Results input={input} /> : null }
</div>
);
};

export default Test;

Thanks a lot. That was pretty simplešŸ«”

Just add {enabled: !!input} to query

Ok i've added that something like that before, but not working. Maybe I put the wrong state there.
