Does cjstoesm get dependent sources from node_modules (am I using it correctly)?

[veikkoeeva]

I was using this module to try to solve a pesky Error: 'default' is not exported by node_modules\<xyz> problem. But it didn't go as planned, so in my desperation reaching here to double-check if this is a problem that in principle is what this module should solve. 🔢

As it may be that I do not understand correctly that if this module indeed would solve, at least in some cases, such problems. It looks to be these are because of UMD -> ES6 export changes, but I may be wrong. The other things are that I think I should also use @rollup/plugin-node-resolve to resolve paths. Is this right?

I have defined

import resolve from '@rollup/plugin-node-resolve';
import ts from "@wessberg/rollup-plugin-ts";
import {cjsToEsm} from "cjstoesm";

[...]

plugins: [    
    resolve({ browser: true, preferBuiltins: true }),
    ts({ transformers: [cjsToEsm()] })
  ]

Another thing is, does this plugin pick up also the dependencies that are referenced by the libraries imported by the code?

(That config is at https://github.com/veikkoeeva/erc1155sample/blob/main/web/rollup.config.js#L27 if it matters, and strangely there is a difference in output if I move it from baseConfig to the merge section, though it's not related to this module).
