Including a specific module in rollup build

Question

I'm using Rollup to build a UMD version of my module.

This rollup.config.js successfully builds my module, without including @tensorflow/tfjs:

import path from 'path';
import commonjs from '@rollup/plugin-commonjs';
import { nodeResolve } from '@rollup/plugin-node-resolve';

export default {
  input: "dist/tmp/index.js",
  output: {
    file: "dist/umd/index.js",
    format: 'umd',
    name: 'Foo',
    globals: {
      '@tensorflow/tfjs': 'tf',
    }
  },
  context: 'window',
  external: ['@tensorflow/tfjs'],
}

However, I rely on a second module (tensor-as-base64) that I do want to include in the bundle. I cannot figure out how to include that specific module.

From a lot of googling it seems like I need to use @rollup/plugin-commonjs and @rollup/plugin-node-resolve, but I can't find any examples for how to scope the includes to a specific folder under node_modules. I've tried something like this:

import commonjs from '@rollup/plugin-commonjs';
import { nodeResolve } from '@rollup/plugin-node-resolve';

export default {
  input: "dist/tmp/index.js",
  output: {
    file: "dist/umd/index.js",
    format: 'umd',
    name: 'Foo',
    globals: {
      '@tensorflow/tfjs': 'tf',
    }
  },
  context: 'window',
  external: ['@tensorflow/tfjs'],
  plugins: [
    nodeResolve({
    }),
    commonjs({
      include: [/tensor-as-base64/],
      namedExports: {
        'tensor-as-base64': ['tensorAsBase64'],
      },
    }),
  ]
};

This seems to just hang with no output.

Any tips on how to include a single specific module from the node_modules folder (and ignore everything else in that folder)?

Update 1

I tried this config:

export default {
  input: "dist/tmp/index.js",
  output: {
    file: "dist/umd/index.js",
    format: 'umd',
    name: 'Foo',
    globals: {
      '@tensorflow/tfjs': 'tf',
    }
  },
  context: 'window',
  external: ['@tensorflow/tfjs'],
  plugins: [
    nodeResolve({
      resolveOnly: [
        /^(?!.*(@tensorflow\/tfjs))/,
      ],
    }),
  ],
})

This produces the following output:

dist/tmp/index.js → dist/umd/index.js...
[!] Error: 'default' is not exported by ../../node_modules/tensor-as-base64/dist/index.js, imported by dist/tmp/upscale.js

Which is accurate in that tensor-as-base64 does not export default.

After including the commonjs plugin, it gets into an infinite loop. I think that's where I'm missing some bit of configuration.

I should add that this is a monorepo, so maybe there's an issue with node_modules being at the root of the folder?
