16c057d: Breaking Change: Performance Optimization for
styled
When a component is wrapped in
styled
, Linaria needs to determine if that component is already a styled component. To accomplish this, the wrapped component is included in the list of variables for evaluation, along with the interpolated values used in styles. The issue arises when a wrapped component, even if it is not styled, brings along a substantial dependency tree. This situation is particularly evident when usingstyled
to style components from third-party UI libraries.To address this problem, Linaria will now examine the import location of the component and check if there is an annotation in the
package.json
file of the package containing the components. This annotation indicates whether the package includes other Linaria components. If there is no such annotation, Linaria will refrain from evaluating the component.Please note that this Breaking Change solely affects developers of component libraries. In order for users to style components from your library, you must include the
linaria.components
property in the library'spackage.json
file. This property should have a mask that covers all imported files with components. Here's an example of how to specify it:"linaria": { "components": "**/*" }
