npm i -D vite-plugin-sass-dts
For version 1.3.27 or later, please use the latest sass-embedded package; we have confirmed that it does not work with the sass package.
| Parameter | Type | Description |
|---|---|---|
| enabledMode | string[] | Create d.ts files for css modules of file extension css, sass, scss included in the project at build time.Valid enumerations 'development' and 'production'. By default it is enabled only for development.We recommend that you turn off the flag once you have created the d.ts file, as it will take a long time to build. (default [development]) |
| global.generate | boolean | Outputs the common style set in additionalData of preprocessorOptions as a global type definition file. |
| global.outputFilePath | string | Specify the file that outputs the global common style with an absolute path.Relative paths will be supported. |
| typeName.replacement | string | (fileName: string) => string | Type name can be changed to any value. (default is the classname key as a string. e.g. theClassName: 'theClassName';) |
| exportName.replacement | string | (fileName: string) => string | Export name can be changed to any value. (default is 'classNames'. e.g. declare const classNames: { ... };) |
| outputDir | string | An absolute path to the output directory. If undefined, declaration files will be generated in the source directories. `) |
| sourceDir | string | An absolute path to your source code directory. The plugin will replace this path with outputDir option when writing declaration files. `) |
| esmExport | boolean | Specify dts export type. If enabled, going to use ESM style export export default .... Otherwise export = .... |
| prettierFilePath | string | Specify the path to the prettier configuration file. |
| useNamedExport | boolean | Output also in named export.(default: false) |
| legacyFileFormat | boolean | Use legacy file naming format. If true, generates *.scss.d.ts (legacy). If false, generates *.d.scss.ts (TypeScript 5 compatible). (default: false) |
import { defineConfig } from 'vite'
import sassDts from 'vite-plugin-sass-dts'
// https://vitejs.dev/config/
export default defineConfig({
plugins: [sassDts()],
})
You can create a dts file by saving the scss file during development. You can check the usage example when the following options are set. Prepare the vite.config.ts file with the following options and start it in development mode.
[vite.config.ts]
import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
import sassDts from 'vite-plugin-sass-dts'
import path from 'path'
export default defineConfig({
css: {
preprocessorOptions: {
scss: {
additionalData: `@use "@/styles" as common;`,
importer(...args) {
if (args[0] !== '@/styles') {
return
}
return {
file: `${path.resolve(__dirname, './src/assets/styles')}`,
}
},
},
},
},
plugins: [
react(),
sassDts({
enabledMode: ['development', 'production'],
global: {
generate: true,
outputFilePath: path.resolve(__dirname, './src/style.d.ts'),
},
sourceDir: path.resolve(__dirname, './src'),
outputDir: path.resolve(__dirname, './dist'),
}),
],
})
npm run dev
Then save the following file ...
[src/assets/styles/_index.scss]
.row {
display: flex;
}
[src/App.module.scss]
.header-1 {
background-color: common.$primary;
&.active {
background-color: black;
}
}
.input {
@media (min-width: 768px) {
max-width: 370px;
}
}
Saving the scss file creates a d.ts file in the outputDir hierarchy.
Note: if
outputDiris not set, declaration files are output to the same directory as the source files.
TypeScript 5 Compatibility: By default, declaration files are generated in the format
*.d.scss.ts(e.g.,App.module.d.scss.ts) which is compatible with TypeScript 5's module resolution. To use the legacy format*.scss.d.ts, setlegacyFileFormat: truein the plugin options.
[dist/App.module.d.scss.ts]
import globalClassNames, { ClassNames as GlobalClassNames } from './style.d'
declare const classNames: typeof globalClassNames & {
readonly 'header-1': 'header-1'
readonly active: 'active'
readonly input: 'input'
}
export = classNames
The optional global type definition is output to the output path of the common style specified in the options.
[src/style.d.ts]
declare const classNames: {
readonly row: 'row'
}
export = classNames

This is a simple calculator app - a replica of the iOS Calculator. It is built using React, styled with CSS modules, and leverages the useState and useEffect hooks for state management and side effects.
