Adds support for baseUrl overwrite using TS_NODE_BASEURL environment variable.

First off, thanks for this library! It seems that several people are running into a case where they need to change the baseUrl to get this working after running tsc. So far most of the solutions look to be either:

1. Creating a bootstrap js file for the sole purpose of changing baseUrl
2. Extending tsconfig.json to extend the orginal tsconfig.json and then set baseUrl based on that

It seems like the simplest solution would be to allow changing the baseUrl via environment variable instead of either of the above options.

Good job, really looking forward for this update.

ts-node allows specifying overrides within your tsconfig.json; it might make sense for tsconfig-paths to detect a ts-node hook and grab the compiler options from there.

{
  "ts-node": {
    "compilerOptions": {
      "baseUrl": "overridden for ts-node"
    }
  },
  "compilerOptions: {
    "baseUrl": "this one is used by tsc"
    // ...
}

// detect ts-node and get options
process[Symbol.for('ts-node.register.instance')].config.options

Seems like some ppl find this useful so I will merge it.

However there seems to be some merge conflicts that needs attending to first.

Hi,

Any updates on this?
This PR is very useful. Without this env var, we are forced to either use any of the workarounds mentioned by the OP or use a third-party package like tscpaths or tsc-alias. This feature is more convenient than these workarounds and keeps our dependency tree less crowded.

I'd appreciate it if you could merge/release this as soon as possible.

[jonaskello]

If someone could resolve the conflicts a merge would be possible.

I am willing to contribute but I don't have write access to this repository. Do you want me to submit a new PR?

[jonaskello]

@information-security Yes, please make a new PR.
