You should not use <Link> outside a <Router>

I'm trying to set up react-router in an example application, and I'm getting the following error:

You should not use <Link> outside a <Router>

My app is set up like so:

Parent component

const router = (
  <div className="sans-serif">
    <Router histpry={browserHistory}>
      <Route path="/" component={Main}>
        <IndexRoute component={PhotoGrid}></IndexRoute>
        <Route path="/view/:postId" component={Single}></Route>
      </Route>
    </Router>
  </div>
);

render(<Main />, document.getElementById('root'));

Child/Main component

export default () => (
  <div>
    <h1>
      <Link to="/">Redux example</Link>
    </h1>
  </div>
)

Any idea what I'm doing wrong here?

Here's a Sandbox link to demonstrate the problem.

Solution 1:

For JEST users

if you use Jest for testing and this error happen just wrap your component with <BrowserRouter>

describe('Test suits for MyComponentWithLink', () => {
it('should match with snapshot', () => {
const tree = renderer
  .create(
    <BrowserRouter>
      <MyComponentWithLink/>
    </BrowserRouter>
  )
  .toJSON();
 expect(tree).toMatchSnapshot();
 });
});

Solution 2:

I'm assuming that you are using React-Router V4, as you used the same in the original Sandbox Link.

You are rendering the Main component in the call to ReactDOM.render that renders a Link and Main component is outside of Router, that's why it is throwing the error:

You should not use <Link> outside a <Router>

Changes:

1. Use any one of these Routers, BrowserRouter/HashRouter etc..., because you are using React-Router V4.

2. Router can have only one child, so wrap all the routes in a div or Switch.

3. React-Router V4, doesn't have the concept of nested routes, if you wants to use nested routes then define those routes directly inside that component.

Check this working example with each of these changes.

Parent Component:

const App = () => (
  <BrowserRouter>
    <div className="sans-serif">
      <Route path="/" component={Main} />
      <Route path="/view/:postId" component={Single} />
    </div>
  </BrowserRouter>
);

render(<App />, document.getElementById('root'));

Main component from route

import React from 'react';
import { Link } from 'react-router-dom';

export default () => (
  <div>
    <h1>
      <Link to="/">Redux example</Link>
    </h1>
  </div>
)

Etc.
