ts-node should not be default when --import flag is present #2157
Description
- Versions: [email protected], [email protected]
nodemon -v: 2.0.20- Operating system/terminal environment (powershell, gitshell, etc): Mac / VS Code shell
- Using Docker? What image: No
- Command you ran:
cross-env IS_LOCAL=true \"NODE_OPTIONS=--import ./register-hooks.js\" IS_RUNNING_LOCALLY=true BASEPLATE_ENV=dev PORT=7601 nodemon --signal SIGINT backend/Server.ts --watch backend --watch migrations --watch frontend --watch docs --ext tsx,ts,js,md,mdx,ejs
See related f7816e4 and #2083. In NodeJS 20, it's possible to customize loader hooks via both the --loader and --import flags, but nodemon currently only accounts for the --loader hook
Expected behaviour
When the --import NODE_OPTIONS flag is present, ts-node should not be the default program to execute .ts and .tsx files.
Actual behaviour
When the --import NODE_OPTIONS flag is present, ts-node is the default program to execute .ts and .tsx files. Note that this can be worked around by creating a nodemon.json file with the following:
{
"execMap": {
"ts": "node",
"tsx": "node"
}
}Steps to reproduce
- Create a
.register.mjsfile that uses https://github.com/node-loader/node-loader-babel to compile typescript files
import { register } from 'node:module';
register("@node-loader/babel", import.meta.url);- Run a typescript program with nodemon:
"NODE_OPTIONS=--import ./register.mjs" nodemon main.tsNote the error that occurs:
sh: ts-node: command not found
[nodemon] failed to start process, "ts-node" exec not found
