typescript with ts-node and ESM support about mocha-examples HOT 7 OPEN

@jordansexton Thank you so much, that worked for me!

package.json

{
	"type": "module"
}

tsconfig.json

{
	"compilerOptions": {
		"module": "esnext",
		"moduleResolution": "node",
	}
}

.mocharc.json

{
	"node-option": [
		"experimental-specifier-resolution=node",
		"loader=ts-node/esm"
	]
}

from mocha-examples.

FWIW, here's a configuration for Mocha, TypeScript, and ESM that finally worked for me:

"node-option": ["experimental-specifier-resolution=node", "loader=ts-node/esm"] was the clincher.

Thanks to all of you here, it helped me a lot :-)

I would simply add that one requirement is to use mocha@9 ([email protected] for me) as I was on mocha@8 and I was getting following error :

TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts"

from mocha-examples.

Thanks. Time permitting I'll send a pull request with a sample. Till then, I'm subscribed to this thread and can answer questions.

I'm looking for a solution on this as well

Hi everyone else from search results.

This only works on node 16, haven't been able to get it to work on 18 or 20.

Newer nodes don't like, and don't need(?) the "experimental-specifier-resolution=node",
