babel-plugin-emotion-rename

Automatically rename legacy emotion imports to new supported emotion versions

Demo repository with Webpack+Babel+React+Emotion11

How it works

• Scan all imports, try to rename legacy import from emotion / react-emotion to @emotion/css
• If it used styled, add additional new import @emotion/styled
• If the emotion.css is used within styled, swap with css method from @emotion/react

Compatibility:

• Legacy v9 to v11
• Some things may not be working, please checkout with caution!
• If you're using SSR, It's very recommended to also implement @emotion/css SSR integration as well for smoother migration

Known issues:

• If you import a variable from another file, and that variable is used within styled/css tagged template literal, then it's currently impossible to statically analyze and rename the import
