That’s exactly why we created our Babel plugin, when using it you’ll get class names that include the name you gave your component:
<div class="Sidebar__Button-KSdffgy oPwefl">
On top of that we set the displayName of the generated component too, which means in your React DevTools you’ll see the actual component name rather than just <div> or <Styled(Component)>.
To use the Babel plugin install it with npm install --save-dev babel-plugin-styled-components and then add it to your Babel configuration: (e.g. in your .babelrc)
plugins: ["styled-components"]
That’s it! Happy debugging 😊
Note that if you’re using create-react-app you cannot change the Babel configuration. I use and would recommend react-app-rewired to be able to change configurations without having to eject. We’ve also built react-app-rewire-styled-components which automatically integrates the styled-components Babel plugin for you!
