How to migrate an existing NestJS app into an Nx monorepo (apps not linking properly)

[soonyubi]

Hi, I’m trying to migrate an existing NestJS application into an Nx monorepo setup.

I’ve already set up a new Nx workspace using npx create-nx-workspace, and then tried moving my existing NestJS app into the apps/ directory. However, I’m having issues where the apps (and libs) are not connecting or recognizing each other properly — for example, import paths or shared modules aren’t resolving as expected.

Here’s what I’m looking for:
• Best practices for migrating an existing standalone NestJS app to Nx
• A reference or guide I can follow for the correct project structure
• Possible reasons why apps might not be linked correctly (e.g., project.json, tsconfig.base.json, or dependency issues)

If anyone has experience with this or can share tips, I’d really appreciate it!

Thanks in advance 🙏
