Ts-node: I'm trying to use ts-node with standard-things/esm. I cannot get it to work.

[Texlo-Dev]

Hi,
So I decided to switch to TypeScript today. In my revious node setup, I was using https://github.com/standard-things/esm for ESM import/export, as Node doesn't support it yet. When trying to run my start script with ts-node -r esm mrFox.ts, I get an error, like so:

import { token } from "./config.json";
       ^

SyntaxError: Unexpected token {
    at new Script (vm.js:79:7)
    at Object.m._compile (/usr/lib/node_modules/ts-node/src/index.ts:439:23)
    at Module._extensions..js (internal/modules/cjs/loader.js:700:10)
    at Object.require.extensions.(anonymous function) [as .ts] (/usr/lib/node_modules/ts-node/src/index.ts:442:12)

This seems to be a result of esm not loading? not sure.
Please help, I would like to be able to use esm with node and ts-node.

In the README of that module it says you need to load it before ts-node.

It does? Where?

Given that you probably have to do something like node -r esm -r ts-node/register.

@blakeembrey your solution worked, thanks!

For some reason, when i run this command more than once, i receive different results. First time is fine, but subsequent times require me to go to another branch and come back which seems very odd. Any suggestions?

I just needed to disable the cache as outlined in the options docs https://github.com/standard-things/esm#options

ESM_DISABLE_CACHE=true TS_NODE_PROJECT=scripts/tsconfig.json node -r esm -r ts-node/register scripts/index.ts
