Is there an existing issue for this?

  • I have searched the existing issues

Current behavior

NestJS only compiles the main project when using the SWC compiler instead of compiling dependencies like it does with TSC.

Here is a minimum reproduction of a working repo with TSC: https://github.com/gabrielbull/nestjs-monorepo-tsc

Minimum reproduction code

https://github.com/gabrielbull/nestjs-monorepo-swc

Steps to reproduce

  1. yarn install
  2. yarn workspace project start

Expected behavior

NestJS should compile both project and lib with SWC like it does with TSC

Package version

10.4.0

NestJS version

10.3.10

Node.js version

20.12.0

In which operating systems have you tested?

  • macOS
  • Windows
  • Linux

I have provided my current workaround in the https://github.com/gabrielbull/nestjs-monorepo-swc repository using the command:

yarn workspace project start:workaround

Basically, only running SWC to compile the lib package manually. Here's what I'm basically doing:

swc --config-file .swcrc --out-dir ./dist --strip-leading-paths --extensions .js,.ts ../lib/src
nest start

It works, but it's annoying to have to use nodemon and custom scripts to replace NestJS built in scripts.
