How to get rid of a query string

Question

SOLVED

I have a kinda stupid issue. I can't get rid of the query string,. Once I put it into the history, I can't find how to remove it.

I have a React app with navigation (Universal Router). I don't believe it is related to the library I use, but rather to a bad use of the URL and History API.

I have a list of users, and each has a number. I have an input form to enter the number. I append this as a query string in the form /users?nb=1 . This url is submitted to a resolver that searches in an array of paths. The action code corresponding to the /users path has a function that reads if a query string is present. If yes, extract the number and push the new path /users/1 . This almost works: I push in fact /users/1?nb=1 ..

Note: I can of course directly push /users/1 without a query string but this is an exercise.

What is the trick?? [EDIT]: override the key search:""

1- the emitting function, creates the query string

function handleSubmit(e) {
    e.preventDefault();
    let query = Object.fromEntries(new FormData(e.currentTarget));
    const {pathname, search} = window.location 
    const qstring = new URLSearchParams(search);
    for (const k in query){ qstring.append(k, query[k])};
    history.push({ pathname, search: "?" + qstring });
  }

1b - vs a "normal" link

const handleClick = (e) => {
    e.preventDefault();
    history.push({ pathname: e.target.pathname });
  };

2- the conditional path (for the query string)

const searchString = new URLSearchParams(window.location.search);
const id = searchString.get("nb");
if (id) { return { redirect: `/users/${id}` } }

3- the resolving

const page = await router.resolve({ pathname: location.pathname });
if (page.redirect) {
    return history.push({ pathname: page.redirect, search: "" });
 }                                                  ^^^!
return render(<React.StrictMode>{page}</React.StrictMode>, root);

The pb is solved by adding search:"" which removes the trailing query string.

Answer 1

So as @Ouroborus showed, you just need to add search:'' in the returned url from the resolver to override the previous query string:

history.push({pathname: page.redirect, search:""})
