ThemeBuilder will be the newest feature of CodeImage that’s allows to create custom themes for both CodeImage and CodeMirror6.

ThemeBuilder will be reachable at themes.codeimage.dev, but it will be also a standalone package that could be used to main CodeImage code (module federation or iframe)

Here’s the features that will be available:

• Authenticated users will be able to create their own themes and manage them in a dedicated section. Themes will be saved in a new backend service
• While creating a theme, you will be able to see also s preview for the CodeMirror theme code
• Themes in the future could be also published and be public for every user (💡featured page)
• CodeImage editor will have a new dedicated section in order to choose about custom or system themes.

Note we could move system themes in the backend

• Themes could be imported from json. Think about a VSCode/IntelliJ parsing in order to import automatically themes

This is an example of an existing ThemeBuilder by CodeSandbox https://sandpack.codesandbox.io/theme
