Details

I've installed ts-node and converted my rspack.config.js file to a typescript file but I believe the docs are incorrect and ts support does not work with export default

documentation shows configuration object being exported using export = config I don't think that's valid ( vscode throws an error as well )

When I use export default config I receive

Configuration error:
- Unrecognized key(s) in object: 'default'

No response

Reproduce Steps

Create a rspack config using typescript
Build

I could help you solve the issue with a long conversation, but the simplest way is to use rspack.config.js.

If you want type checking with rspack.config.js, add @ts-check and @type {import('@rspack/cli').Configuration}.

https://www.rspack.dev/config/#type-checking

// @ts-check

/** @type {import('@rspack/cli').Configuration} */
const config = {
  entry: {
    main: './src/index.js',
  },
};
module.exports = config;

export = xxx is a valid syntax in typescript. The error you met is probably caused by an improper tsconfig.json.

we should support export default case in future, let me test whether #3222 fix it

@ICJR it's supported now, you can test on @rspack/cli@0.2.3-canary-bd53ec4-20230623050741
