Upon transitioning from material-ui v3 to v4, it was observed that the react component/function names were included in the class attribute within the HTML.
Is this normal? Could this potentially cause issues when trying to override class properties with new styles that are not being applied?
Furthermore, is there a way to remove these component names?
The component names include: WrapperComponent, withRouter, CustomerDetailsContainer, and others.
Material-UI utilizes a unique class name generator to create distinct class names for styled components in order to achieve style isolation. The prefix of the class name varies depending on the current environment.
jss is utilizedTo observe the change in class name prefix, you can simulate different environments by adjusting process.env.NODE_ENV at the start of your program.
// Set to "production" to view the difference in class name prefix
process.env.NODE_ENV = "development";
class App extends React.Component {
static displayName = "MyAmazingApp";
render() {
const { classes } = this.props;
return <div className={classes.root}>Hello world</div>;
}
}
const styles = {
root: {
backgroundColor: "grey"
}
};
const AppWithRouter = withRouter(App);
const MyApp = withStyles(styles)(AppWithRouter);
console.log(AppWithRouter.displayName); // withRouter(MyAmazingApp)-root-1
Generated class name for the element in development:
withRouter(MyAmazingApp)-root-1
In a production environment:
