Nrwl Nx build for production missing node modules bundle

I have a Nrwl Nx repo with different apps (angular, nodejs with express) and shared libs inside. The repo was created with the nx cli and I want to build for production one of the express apps.

nx build:production myexpressapp

The bundle I get is very nice and runs if I run it (with pm2) from where it was built (dist folder). However, if I get it to production, the node modules are missing and the app does not start. If I copy the node_modules folder above the one with the built dist it works as well.

But I would very much like either of:

I tried using "vendorChunk":true in my production build options but nothing changes.

Any thoughts?

If you're missing the node_modules folder entirely, you need to add the generatePackageJson option to your project.json

Like so:

"targets": {
    "build": {
      "executor": "@nrwl/webpack:webpack",
      "options": {
        "outputPath": "...",
        "main": "...",
        "tsConfig": "...",
        "assets": [...],
        "generatePackageJson": true,
        "target": "node",
        "compiler": "tsc"
      },
    ...

Looking at angular.json (or workspace.json), if your builder is @nrwl/node:build, under options, set externalDependencies to none, like so:

{
  "projects": {
    "api": {
      "architect": {
        "build": {
          "builder": "@nrwl/node:build",
          "options": {
            "externalDependencies": "none"
            ...

You may experience errors like:

ERROR in ...
Module not found: Error: Can't resolve 'some-modules' in ...

Just keep installing what its complaining about, until it stops.
