Full stack To Do App

I am wondering if I am meant if I have been sending data to my database correctly when considering React. I choose not to use useEffect here as the fetch request isn't effecting the component.

Is it right to not use it here?

const handleSubmit= (e)=>{

    const item =  {
        id:Math.random()*1000,
        text:inputText,
        complete:false
    }

    e.preventDefault()
    setNewItem([...newItem,item

    ])
    setInputText('')
//custom fetch hook
    UseFetch("/api/addOne", "POST", item) }

Plus any other feedback would be welcome
