@stylin/ts-loader

Webpack loader for type auto-generation.

Installation

npm install --save-dev @stylin/ts-loader

In webpack configuration file, place @stylin/ts-loader after @stylin/msa-loader in modules/rules section.

webpack.config.js

module.exports = {
  module: {
    rules: [{
      test: /\.scss$/i,
      use: [
        `@stylin/ts-loader`,
        `@stylin/msa-loader`,
        {loader: MiniCssExtractPlugin.loader}, // it can be `style-loader`
        {loader: `css-loader`, options: {modules: true}},
        `sass-loader`, // optional
      ],
    }],
  }
}

Options

You can customize the generated type names. By default, they are equal:

 propsType: (componentName: string) => `${componentName}Props`
 styledPropsType: (componentName: string) => `Styled${componentName}Props`,

The generated interfaces for User component will be:

💅 *.scss.d.ts

export interface UserProps extends ComponentProps<'div'> {
  status: 'online' | 'busy' | 'offline'
}

export const User: FC<UserProps>

Optional property

For optional component properties, add a question mark as you do in typescript:

/**
  @tag: input
  @component: Input
  disabled?: true
*/

⚠ Webpack watcher

Webpack in watch mode keeps tracking file changes only if it is in the dependency graph. It means if you create a file that is not imported in your application code source, webpack will not track it and will not generate types for it. Before starting coding a new component, first of all, import it into your code and then begin implementation.
