Why Your React Components Aren't Rendering (And How to Fix It)

Now react components wont render for various reasons.

---

The most common reason is because you arent exporting it.

Lets say you make a component called App.jsx but you forgot to export function App()

The most common way to render this is using export default

An example: export default FunctionName;

You can choose to export your function at the very bottom of your file, or inline at the top. Using an inline export is often cleaner because you don't have to remember to add it at the end.

for example:

export default function App() {
  return(
    <div id="App">
      <header>
        <h1>No need to use export default FunctionName; at the end</h1>
      </header>
      <main>
        <article>
          <p>This is because you can export default then make the function so you dont need it at the end</p>
        </article>
      </main>
    </div>
  );
}

Another common cause is your function isnt returning anything or you forgot to add return

for single JSX code you can do: return SingleLineJsxCode; ( REPLACE SingleLineJsxCode WITH Your Single lined JSX code )

for multi-line JSX code you can do:

return(
  <div id="App">
    {/* Your Jsx Code Here*/}
  </div>
);

once you have that in your react component's functions then it can render correctly

It can also be because your code errored in the component before the render.

Make sure to check your output and fix errors.
