Passing --project to ts-node when it's registered with nodemon

This command is used to run my server:1

nodemon
  -r ts-node/register
  -r tsconfig-paths/register
  --watch server/
  --watch shared/
  --ext ts,tsx,json
  --inspect-brk=24170
  ./server/index.ts

The problem is, I need ts-node to receive --project ./tsconfig-server.json rather than using the default tsconfig.json. Simply including it after the -r ts-node/register (or anywhere else) results in a bad option: --project error.

Using --exec 'node ./node_modules/ts-node/dist/bin.js --project ./tsconfig-amd.json' instead of -r ts-node/register works, but then the debugger fails to attach to the process. I assume that’s because it’s trying to attach to the nodemon process rather than the node process that nodemon starts?

But I cannot use the default tsconfig.json filename here, because VS Code does not support specifying an alternative tsconfig.json and the server config is not the one I want to use for viewing and editing the code

  1. The command is actually produced by VS Code per my .vscode/launch.json which looks like this: 
    {

    // Hover to view descriptions of existing attributes.

You need to pass the --project value trough the "TS_NODE_PROJECT" environment variable. I do it in my nodemon.json file

{
    "restartable": "rs",
    "ignore": [".git", "node_modules/**/node_modules", "src/client"],
    "verbose": true,
    "execMap": {
      "ts": "node --require ts-node/register/transpile-only --require tsconfig-paths/register"
    },
    "watch": ["src/server", "typing"],
    "env": {
      "NODE_ENV": "development",
      "TS_NODE_PROJECT": "src/server/tsconfig.json"
    },
    "ext": "js,json,ts"
}
