node compat: parseArgs doesn't support default option

[sigmaSd]

Version: Deno 1.40.5

import { parseArgs } from "node:util";

const parsedArgs = parseArgs({
  options: { hello: { type: "string" } },
  allowPositionals: true,
});

console.log(parsedArgs);

node a.js --args hello a

{ values: [Object: null prototype] { hello: 'a' }, positionals: [] }

deno run a.js --args hello a

error: Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'execArgv')

the above is already tracked by #22363

But the behavior is still not the same

import { parseArgs } from "node:util";

const parsedArgs = parseArgs({
  args: [],
  options: {
    handler: {
      type: "string",
      default: "hello",
    },
  },
});

console.log(parsedArgs.values.handler);

Running with not arguments

deno -> undefined
nodejs -> hello

Fix underway: #22363 #22405

I see , but there behaviour is still missing some parts:

import { parseArgs } from "node:util";

const parsedArgs = parseArgs({
  args: [],
  options: {
    handler: {
      type: "string",
      default: "hello",
    },
  },
});

console.log(parsedArgs.values.handler);

Running with no arguments

deno -> undefined
nodejs -> hello

I guess its just missing support for default

[shadowspawn]

The support for defaults was added in: nodejs/node#44631
