@emotion/sheet

What is @emotion/sheet?

The @emotion/sheet package is part of the Emotion library, which is a popular CSS-in-JS library that allows developers to write CSS styles with JavaScript. The @emotion/sheet package provides a low-level utility for managing style sheets. It is used internally by Emotion to insert styles into the DOM, but it can also be used directly for more control over how styles are inserted.

What are @emotion/sheet's main functionalities?

Creating and inserting a style sheet

This feature allows you to create a new style sheet and insert CSS rules into it. The 'speedy' option enables faster insertion of rules by using CSSOM APIs.

{"import { StyleSheet } from '@emotion/sheet';\nconst sheet = new StyleSheet({ speedy: true });\nsheet.insert('.css-12345 { color: hotpink; }');"}

Flushing styles

This feature allows you to remove all rules from the style sheet. This can be useful for cleaning up styles in server-side rendering or during hot module replacement in development.

{"import { StyleSheet } from '@emotion/sheet';\nconst sheet = new StyleSheet({ speedy: true });\nsheet.insert('.css-12345 { color: hotpink; }');\nsheet.flush();"}
