v4-rc.1 notes (breaking changes)

Using v4-rc.1​

First, you need to install peer dependencies:

npm install @emotion/react@^11.10.0 @emotion/styled@^11.10.0 styled-system@^5.1.5 @styled-system/should-forward-prop@^5.1.5

Install the package through npm or yarn:

Only the core package is available as version 4.0.0-rc.1

npm install @desygna/desygna-core@4.0.0-rc.1

Improvements​

Type-safety on theme variables​

You can define your theme as a type definition, which will allow you to create components that are fully type-safe using your custom theme tokens. With this approach, you only need to include a few files to achieve this functionality.

By having a theme.ts file that defines your custom theme and a desygna.d.ts file that provides type definitions for the Desygna library, you can get typings in your code editor (such as VS Code). This means that your editor will provide autocomplete suggestions and type-checking for your custom theme properties, making it easier and faster to write type-safe components.

/**
 *

 * you need to have a theme.ts file for your custom theme and a desygna.d.ts file
