Working with nuqs

Manage React state in URL query parameters with nuqs. Covers Suspense boundaries, parsers, clearing state, and deep-linkable dialogs.

Implement Working with nuqs

Manage React state in URL query parameters with nuqs for shareable filters, search, and deep-linkable dialogs.

Suspense Boundary Pattern

nuqs uses useSearchParams behind the scenes, requiring a Suspense boundary. Wrap nuqs-using components with Suspense via a wrapper component to keep the boundary colocated:

import { Suspense } from "react";

type SearchInputProps = {
  placeholder?: string;
};

// Public component with built-in Suspense
export function SearchInput(props: SearchInputProps) {
  return (
    <Suspense fallback={<input placeholder={props.placeholder} disabled />}>
      <SearchInputClient {...props} />
    </Suspense>
  );
}



"use client";

import { useQueryState, parseAsString } from "nuqs";

// Internal client component that uses nuqs
function SearchInputClient({ placeholder = "Search..." }: SearchInputProps) {
  const [search, setSearch] = useQueryState("q", parseAsString.withDefault(""));

  return (
    <input
      value={search}
      onChange={(e) => setSearch(e.target.value || null)}
      placeholder={placeholder}
    />
  );
}

This pattern allows consuming components to use SearchInput without adding Suspense themselves.

State to URL Query Params

Replace useState with useQueryState to sync state to the URL:

"use client";

import {
  useQueryState,
  parseAsString,
  parseAsBoolean,
  parseAsArrayOf,
} from "nuqs";

// String state (search, filters)
const [search, setSearch] = useQueryState("q", parseAsString.withDefault(""));

// Boolean state (toggles)
const [showArchived, setShowArchived] = useQueryState(
  "archived",
  parseAsBoolean.withDefault(false),
);

// Array state (multi-select)
const [tags, setTags] = useQueryState(
  "tags",
  parseAsArrayOf(parseAsString).withDefault([]),
);

Clear State

Set to null to remove from URL:

// Clear single param
setSearch(null);

// Clear all filters
function clearFilters() {
  setSearch(null);
  setTags(null);
  setShowArchived(null);
}

When using .withDefault(), setting to null clears the URL param but returns the default value.

Deep-Linkable Dialogs

Control dialog visibility with URL params for shareable links:

import { Suspense } from "react";

type DeleteDialogProps = {
  onDelete: (id: string) => Promise<void>;
};

// Public component with built-in Suspense
export function DeleteDialog(props: DeleteDialogProps) {
  return (
    <Suspense fallback={null}>
      <DeleteDialogClient {...props} />
    </Suspense>
  );
}



"use client";

import { useQueryState, parseAsString } from "nuqs";
import { AlertDialog, AlertDialogContent } from "@/components/ui/alert-dialog";

function DeleteDialogClient({ onDelete }: DeleteDialogProps) {
  const [deleteId, setDeleteId] = useQueryState("delete", parseAsString);

  async function handleDelete() {
    if (!deleteId) return;
    await onDelete(deleteId);
    setDeleteId(null);
  }

  return (
    <AlertDialog open={!!deleteId} onOpenChange={(open) => !open && setDeleteId(null)}>
      <AlertDialogContent>
        {/* Confirmation UI */}
        <Button onClick={handleDelete}>Delete</Button>
      </AlertDialogContent>
    </AlertDialog>
  );
}

Open the dialog programmatically:

// Open delete dialog for specific item
setDeleteId("item-123");

// Deep link: /items?delete=item-123

Opening Dialogs from Buttons

Use a trigger button to open the dialog:

function ItemRow({ item }: { item: Item }) {
  const [, setDeleteId] = useQueryState("delete", parseAsString);

  return (
    <Button variant="ghost" onClick={() => setDeleteId(item.id)}>
      Delete
    </Button>
  );
}
