trouble with modules in repl - node.js

Question

i am having a hell of time trying to set up a custom repl app. I did a bunch of googling and managed to wrange the code below and got a working repl shell.
script.js
const repl = require("repl")
function evaluate(command, context, filename, callback) {
callback(null, command)
}
repl.start({
prompt: ": ",
eval: evaluate
});
so after getting this prototype working i decided to add a module to split the routing of the command processing. I made a tracker.js module and required it in my script.js
tracker.js
export default class Tracker {
static Process(command) {
console.log(command)
}
}
script.js added the require statement.
const repl = require("repl")
const Tracker = require("./tracker")
function evaluate(command, context, filename, callback) {
callback(null, command)
}
repl.start({
prompt: ": ",
eval: evaluate
});
after i reran this i got an error saying,
SyntaxError: Unexpected token 'export'

so i went back to google and found some tips saying to add type:module to the package.json. so i did this and reran and now i get this error,
ReferenceError: require is not defined in ES module scope, you can use import instead
This file is being treated as an ES module because it has a '.js' file extension and 'C:\Users\e212034\repository\repl\package.json' contains "type": "module". To treat it as a CommonJS script, rename it to use the '.cjs' file extension.

i tried changing the module to .mjs no luck. i tried changing the type to commonjs and the module to .cjs no luck on either.
any ideas on how to resolve this issue?
