Sample ts-node project with ESM

Created this project with the purpose of having a template for typescript node projects with ES modules working.

Key takeaways

I had some issues when trying to make this work, they were mainly my fault but I would like to have them documented so that no one else have to go through this as well.

• add "type":"module" to your package.json
• Add at least the following keys to your tsconfig.json:

  "compilerOptions": {
    "module": "ESNext",
    "moduleResolution": "NodeNext"
  },
  "ts-node": {
    "esm": true
  },

• Make sure you have nodemon and ts-node installed as Dev deps. Note ts-node version should be higher than 10.8

    npm i -D nodemon ts-node

  I had some issues with this, I think I had an outdated version of ts-node that was causing conflicts and giving me ERR_UNKNOWN_FILE_EXTENSION errors.

• Make sure the imports you use end with .js (even if they are .ts). Note the file extension of imports in index.ts .

  With "moduleResolution":"NodeNext" in tsconfig.json the import should autocomplete properly when using vscode's auto-import suggestion

• baseUrl from tsconfig.json is not working with ts-node + esm , so import should be all relative when using this configuration
