I want to fetch Dynamic API routing after enter submit with input state. but I don't know how to pass state from react to getServerSideProps.
this is my code
export default function Home(props) {
const { data } = props;
const [input, setInput] = useState("");
const handlerChange = (event) => {
setInput(event.target.value);
};
const handlerSubmit = () => {
console.log(event.target.value);
setInput("");
};
return (
<input
type="text"
className="form-control"
placeholder="Group Name"
value={input}
onChange={handlerChange}
onKeyDown={(event) =>
event.key === "Enter" && handlerSubmit(event)
}
/>
)
export async function getServerSideProps() {
const res = await fetch(`http://localhost:3000/api/searchGroup/${input}`)
const data = await res.json()
return { props: { data } }
}
You could use a dynamic route instead to navigate to something like a /your-current-page/${input}
and you would then have access to the input value as a param in getServerSideProps as such:
export async function getServerSideProps({ params }) {
const { input } = params;
...
}
More info on this here
You should make the request with the updated input
value from the client-side instead inside the handlerSubmit
callback and save the data
to be rendered in a state variable (eg dataToRender
).
const getData = async (input) => {
const res = await fetch(`http://localhost:3000/api/searchGroup/${input}`)
return res.json()
}
export default function Home(props) {
const { data } = props;
const [dataToRender, setDataToRender] = useState(data);
const [input, setInput] = useState("");
const handlerChange = (event) => {
setInput(event.target.value);
};
const handlerSubmit = async (event) => {
setInput("");
const newData = await getData(event.target.value);
setDataToRender(newData);
};
return (
<input
type="text"
className="form-control"
placeholder="Group Name"
value={input}
onChange={handlerChange}
onKeyDown={(event) =>
event.key === "Enter" && handlerSubmit(event)
}
/>
)
}
As an alternative to the above, if you absolutely need to have the request in getServerSideProps
, then you can pass the input
value as a query parameter and read it from context.query.input
in getServerSideProps
.
// On the client-side
import { useRouter } from "next/router";
export default function Home(props) {
const router = useRouter()
const handlerSubmit = () => {
console.log(event.target.value);
setInput("");
router.push(`${router.pathname}?input=${event.target.value}`);
}
// Remaining code...
}
// On the server-side
export async function getServerSideProps(context) {
const res = await fetch(`http://localhost:3000/api/searchGroup/${context.query.input ?? 'default-value'}`)
const data = await res.json()
return { props: { data } }
