JavaScript React Router 4 Basics Getting Started with React Router Installing React Router and Declaring Routes

Links must not point to "#". Use a more descriptive href or use a button instead

Getting this error. Why is that? That was after I added the Header component to the JSX in app.js.

1 Answer

Inside the Header.js component you should see something like this:

<header>
    <span className="icn-logo"><i className="material-icons">code</i></span>
    <ul className="main-nav">
      <li><a href="#">Home</a></li>
      <li><a href="#">About</a></li>
      <li><a href="#">Teachers</a></li>
      <li><a href="#">Courses</a></li>
    </ul>    
</header>

This error is being thrown by the href="#" in the link tags because create-react-app warns designers against bad practices. Designers usually use href="#" as placeholder for links but create-react-app warns us that we should change it to an actual route because it doesn't do anything and we might have made a mistake.
