useLocation is a React hook that returns the current location object, which contains information about the current URL including pathname, search parameters, hash, and navigation state. It’s re-exported from react-router v7.
Always import useLocation from @tailor-platform/app-shell, not from react-router directly. AppShell manages its own router instance, and importing from the wrong package will cause the hook to return incorrect values.

​
Usage

import { useLocation } from '@tailor-platform/app-shell';

const MyComponent = () => {
  const location = useLocation();

  return <div>Current path: {location.pathname}</div>;
};

​
Signature

const location: Location = useLocation();

interface Location {
  pathname: string;      // Current URL path (e.g., "/orders/123")
  search: string;        // Query string (e.g., "?tab=details&sort=asc")
  hash: string;          // URL hash (e.g., "#section")
  state: any;           // State passed via navigate() or Link
  key: string;          // Unique key for this location
}

​
Examples

​
Access Current Path

import { useLocation } from '@tailor-platform/app-shell';

const Breadcrumbs = () => {
  const location = useLocation();
  const paths = location.pathname.split('/').filter(Boolean);

  return (
    <nav>
      {paths.map((path, index) => (
        <span key={index}>
          {index > 0 && ' / '}
          {path}
        </span>
      ))}
    </nav>
  );
};

​
Access Query Parameters

import { useLocation } from '@tailor-platform/app-shell';

const ProductList = () => {
  const location = useLocation();
  const searchParams = new URLSearchParams(location.search);
  
  const category = searchParams.get('category') || 'all';
  const sortBy = searchParams.get('sort') || 'name';

  return (
    <div>
      <h1>Products - Category: {category}</h1>
      <p>Sorted by: {sortBy}</p>
    </div>
  );
};

​
Track Navigation State

Access state passed from the previous page: 
import { useLocation, useNavigate } from '@tailor-platform/app-shell';

// Source page
const OrderList = () => {
  const navigate = useNavigate();
  
  const createOrder = () => {
    navigate('/orders/new', {
      state: { returnTo: '/orders', filter: 'pending' }
    });
  };

  return <button onClick={createOrder}>Create Order</button>;
};

// Destination page
const NewOrderPage = () => {
  const location = useLocation();
  const navigate = useNavigate();
  const { returnTo, filter } = location.state || {};

  const handleCancel = () => {
    if (returnTo) {
      navigate(returnTo);
    } else {
      navigate('/orders');
    }
  };

  return (
    <div>
      <h1>New Order</h1>
      <button onClick={handleCancel}>Cancel</button>
      {filter && <p>Will return to {filter} orders</p>}
    </div>
  );
};

​
Conditional Rendering Based on Path

import { useLocation } from '@tailor-platform/app-shell';

const Header = () => {
  const location = useLocation();
  const isOrdersPage = location.pathname.startsWith('/orders');

  return (
    <header>
      <h1>My App</h1>
      {isOrdersPage && <OrderFilters />}
    </header>
  );
};

​
Highlight Active Navigation Items

import { useLocation, Link } from '@tailor-platform/app-shell';

const Navigation = () => {
  const location = useLocation();

  const navItems = [
    { path: '/dashboard', label: 'Dashboard' },
    { path: '/orders', label: 'Orders' },
    { path: '/products', label: 'Products' },
  ];

  return (
    <nav>
      {navItems.map((item) => (
        <Link
          key={item.path}
          to={item.path}
          style={{
            fontWeight: location.pathname === item.path ? 'bold' : 'normal',
            color: location.pathname === item.path ? 'blue' : 'black',
          }}
        >
          {item.label}
        </Link>
      ))}
    </nav>
  );
};

​
Sync UI with URL

import { useLocation, useNavigate } from '@tailor-platform/app-shell';
import { useEffect, useState } from 'react';

const TabbedView = () => {
  const location = useLocation();
  const navigate = useNavigate();
  const searchParams = new URLSearchParams(location.search);
  const activeTab = searchParams.get('tab') || 'details';

  const setActiveTab = (tab: string) => {
    const newParams = new URLSearchParams(location.search);
    newParams.set('tab', tab);
    navigate(`${location.pathname}?${newParams.toString()}`);
  };

  return (
    <div>
      <div>
        <button onClick={() => setActiveTab('details')}>Details</button>
        <button onClick={() => setActiveTab('history')}>History</button>
        <button onClick={() => setActiveTab('notes')}>Notes</button>
      </div>
      
      {activeTab === 'details' && <DetailsTab />}
      {activeTab === 'history' && <HistoryTab />}
      {activeTab === 'notes' && <NotesTab />}
    </div>
  );
};

​
Analytics and Tracking

import { useLocation } from '@tailor-platform/app-shell';
import { useEffect } from 'react';

const Analytics = () => {
  const location = useLocation();

  useEffect(() => {
    // Track page view
    analytics.track('page_view', {
      path: location.pathname,
      search: location.search,
    });
  }, [location.pathname, location.search]);

  return null;
};

​
Scroll Restoration

import { useLocation } from '@tailor-platform/app-shell';
import { useEffect, useRef } from 'react';

const ScrollManager = () => {
  const location = useLocation();
  const prevLocation = useRef(location);

  useEffect(() => {
    // Scroll to top on route change (unless hash is present)
    if (location.pathname !== prevLocation.current.pathname) {
      if (!location.hash) {
        window.scrollTo(0, 0);
      }
    }
    prevLocation.current = location;
  }, [location]);

  return null;
};

​
Working with Search Parameters

​
Using URLSearchParams

import { useLocation } from '@tailor-platform/app-shell';

const FilteredList = () => {
  const location = useLocation();
  const params = new URLSearchParams(location.search);
  
  // Get single value
  const category = params.get('category');
  
  // Get multiple values
  const tags = params.getAll('tag');
  
  // Check if param exists
  const hasSort = params.has('sort');
  
  // Get all params as object
  const allParams = Object.fromEntries(params.entries());

  return (
    <div>
      <p>Category: {category}</p>
      <p>Tags: {tags.join(', ')}</p>
      <p>Has sort: {hasSort.toString()}</p>
      <pre>{JSON.stringify(allParams, null, 2)}</pre>
    </div>
  );
};

​
Updating Query Parameters

import { useLocation, useNavigate } from '@tailor-platform/app-shell';

const SearchFilters = () => {
  const location = useLocation();
  const navigate = useNavigate();

  const updateFilter = (key: string, value: string) => {
    const params = new URLSearchParams(location.search);
    params.set(key, value);
    navigate(`${location.pathname}?${params.toString()}`);
  };

  const removeFilter = (key: string) => {
    const params = new URLSearchParams(location.search);
    params.delete(key);
    navigate(`${location.pathname}?${params.toString()}`);
  };

  return (
    <div>
      <input
        type="text"
        onChange={(e) => updateFilter('search', e.target.value)}
        placeholder="Search..."
      />
      <button onClick={() => removeFilter('search')}>Clear</button>
    </div>
  );
};

​
Common Patterns

​
Create a Custom Hook for Query Params

import { useLocation } from '@tailor-platform/app-shell';
import { useMemo } from 'react';

function useQueryParams() {
  const location = useLocation();
  
  return useMemo(
    () => new URLSearchParams(location.search),
    [location.search]
  );
}

// Usage
const MyComponent = () => {
  const params = useQueryParams();
  const tab = params.get('tab') || 'default';
  
  return <div>Active tab: {tab}</div>;
};

​
Preserve Query Params on Navigation

import { useLocation, useNavigate } from '@tailor-platform/app-shell';

const ProductCard = ({ productId }) => {
  const location = useLocation();
  const navigate = useNavigate();

  const viewProduct = () => {
    // Preserve existing query params when navigating
    navigate(`/products/${productId}${location.search}`);
  };

  return <button onClick={viewProduct}>View Product</button>;
};
