The error: “Component Definition Is Missing Displayname (Reactdisplay-Name)” is becoming popular at the moment. This post will assist you in dealing with this error in a fast and convenient way. Let’s kick in interesting information below.      

When does the error: “Component Definition Is Missing Displayname (Reactdisplay-Name)” happen?

This error: “Component Definition Is Missing Displayname (Reactdisplay-Name)” will occur when you create and develop the react app. 

The “displayName” is not available mostly, so this error will display on your react app’s screen.       

Component definition is missing displayName (react/display-name)

From analyzing this error, we will come up with the main cause:

Displayname is not settled by users – The error is regularly caused by “displayName” which can not be determined precisely for giving a descriptive name to components for the React dev tools extension. 

How to fix this error?

Approach 1: Set “displayName”

As for this case, you need to set the “displayName” property for the component to fix this error. Next, you add “MyApp.displayName” = “MyApp” before you run the project. 

const MyApp = () => {
  return (
   <>
    <div>
<h1>Component definition is missing displayName</h1>
    </div>
  </>
  );
};
MyApp.displayName = 'MyApp';
export default MyApp;

After you set “displayName” above, the error is solved rapidly. 

Approach 2: Try to disable the ESlint rule

The next solution to deal with this error is to disable the Eslint rule. In this case, all you need to do is add a line of comment right above the component. 

// Eslint-disable-next-line react/display-name
const MyApp = () => {
  return (
   <>
    <div>
<h1>Component definition is missing displayName</h1>
    </div>
  </>
  );
};
export default MyApp;

As you can see, the line on the top of the component like “// Eslint-disable-next-line react/display-name” is added successfully. Finally, run the code and the error is fixed completely. 

Approach 3: Disable the react/displayName

To avoid this error, users might disable the react/displayName rule through your program. First of all, you open your “.eslintrc.js” file. Then, insert the “rules property” in the “module. exports”.

module.exports = {
  rules: {
    ....
    "react/display-name": "off",
  }
 }

By doing the double steps above, this error will be fixed effectively.
