This plugin automatically adds dataset(data-*) to every component rendered with styled-components using .attrs method for better debugging and (E2E) Testing. For documentations of styled-components please visit the styled-components official website.

Install the plugin as development dependencies:

npm install --save-dev babel-plugin-styled-components-dataset

Add the following line to your babel configuration:

{
  "plugins": ["styled-components-dataset"]
}

Note The plugin should always placed before babel-plugin-styled-components for now.

Example:

{
   "plugins": [
       "styled-components-dataset",
       [
           "styled-components",
           {
               "ssr": true,
               "displayName": false,
               "minify": true,
           }
       ]
   ]
}

The attrubute name to add.

Example:

in .babelrc

{
  "plugins": [["styled-components-dataset", { "key": "data-test-key" }]]
}

in path/to/TestComponent/index.js

const Container = styled.div`
  width: 100%;
`;

output:

const Container = styled.div.attrs({ 'data-test-key': 'TestComponent_Container' }).div`width: 100%`;
