Details

While the following code runs as expected, the types for Compiler#run only show up if one imports rspack as a named import. Note: this is true in both ESM and CommonJS.

const rspack = require('@rspack/core')

const compiler = rspack(config)

compiler.run(...)

No response

Reproduce Steps

In an rspack project, try the following import scenarios

ESM, has types:

import { rspack } from '@rspack/core'

const configs = require('./path/to/config.js')

const compiler = rspack(configs)

ESM, no types:

import rspack from '@rspack/core'

const configs = require('./path/to/config.js')

const compiler = rspack(configs)

CommonJS, has types:

const { rspack } = require('@rspack/core')

const configs = require('./path/to/config.js')

const compiler = rspack(configs)

CommonJS, no types:

const rspack = require('@rspack/core')

const configs = require('./path/to/config.js')

const compiler = rspack(configs)
