Reproduction repository

https://stackblitz.com/edit/node-ifch93?file=index.ts

Reproduction steps

Use documentation example with typescript https://mswjs.io/docs/getting-started/integrate/browser#configure-worker

// src/mocks/browser.js
import { setupWorker } from 'msw'
import { handlers } from './handlers'

// This configures a Service Worker with the given request handlers.
export const worker = setupWorker(...handlers)

Current behavior

Typescript throws multiple TS4094: Property 'SOMETHING' of exported class expression may not be private or protected.

Expected behavior

I expect typescript to be fine with that

@kettanaito I opened a PR to reuse the existing interface describing the class SetupWorkerApi. For me it is the only way to have it working on the consumer side (without the above workaround), but maybe you want to check the interface SetupWorkerApi is describing well enough the class SetupWorkerApi (at least TS it is matching according to TS)

@gduliscouet-ubitransport Adding the type annotation to the worker constant instead of using TypeScript inference allows me to output the definition file without errors.

import { setupWorker, type SetupWorkerApi } from 'msw';

export const worker:SetupWorkerApi = setupWorker(...[]);
