React error Component definition is missing display name fix
Set the displayName property on the component to fix the "Component definition is missing display name" error, for example App.displayName = 'MyApp';. Alternatively, disable the ESLint rule for the line with the following comment - // eslint-disable-next-line react/display-name.
const App = () => {
return (
<div>
<h2>Hello world</h2>
</div>
);
};
// 设置显示名称
App.displayName = 'MyApp';
export default App;
forwardRefsThis error is usually caused when using React .
The displayName property is used to provide a descriptive name for the React devtools extension's component.
Alternatively, we can disable ESlint rules for a single line by placing a comment right above the ESlint error that occurs.
// eslint-disable-next-line react/display-name
const App = () => {
return (
<div>
<h2>Hello world</h2>
</div>
);
};
export default App;
This comment will disable the rule for a single line.
.eslintrc.jsAlternatively, we can disable a rule for the entire project by adding the property to the rules object of the file react/display-name.
module.exports = {
rules: {
"react/display-name": "off",
}
}
We can also disable the rule for a single file by adding the following comment at the top of the file.
/* eslint-disable react/display-name */
