@nice-labs/typed-css-modules

Creates TypeScript definition files from CSS Modules .css files.

If you have the following css,

/* locals.css */

.local {
}
.local-1 {
}

typed-css-modules creates the following .d.ts files from the above css:

/* locals.css.d.ts */
interface ILocals {
  'local': string;
  'local-1': string;
  [name: string]: string;
}
declare const locals: ILocals;
export = locals;

So, you can import CSS modules' class or variable into your TypeScript sources:

/* app.ts */
import * as locals from './locals.css';
console.log(locals.local);
console.log(locals['local-1']);

API

npm install -D @nice-labs/typed-css-modules

import * as fs from 'fs';
import { promisify } from 'util';
import { getModuleTokens, createTypeHint } from '@nice-labs/typed-css-modules';

const readFile = promisify(fs.readFile);

async function main() {
  const source = await readFile('locals.css');
  const tokens = await getModuleTokens(source); // ["local", "local-1"]
  const typeHint = createTypeHint(tokens); // d.ts file content
}

main();
