SyntaxError: Unexpected token 'export' when starting production build of Node+Express+Socket app with TURBOREPO (monorepo)

[HenriqueRamos13]

Summary

I'm facing an issue when trying to run my Node.js + Express + Socket.io application in production. The app works perfectly in development mode using turbo dev, but when I try to build and start the application in production using npm run build && npm start, I encounter the following error:

@indoor/[email protected] start
> node dist/index.js

/Users/user/dev/indoor/packages/mysql-database/src/index.ts:1
export * from "./prisma";
^^^^^^

Additional Context:

The apps/dashboard app, which is a Next.js app, works fine in both development and production. The problem only occurs in the apps/live-stats-node app when trying to start the production build or when i ran npm run build && npm start inside the app/live-stats directory

I have tried several solutions but haven't been able to resolve this issue. Any help would be greatly appreciated.

edit: I tried to change tsup config, set type: module in package.json and always get some error.

Express.js isn't able to consume TypeScript directly, which is a limitation of Just-In-Time packages. The Next.js application can handle it since it's using webpack or Turbopack for bundling, but Express.js doesn't have a bundler. You may want to switch to a Compiled Package.
