Dynamic require of "util" is not supported

[joeflateau]

I am attempting to write a script that uses node-usb to communicate with a GoPro camera. Node-usb calls require("util") internally. script kit/esbuild does not seem to like this.

// Name: import-gopro

import "@johnlindquist/kit";

import { WebUSB } from "usb";  // error here!

const devices = (
  await new WebUSB({ allowAllDevices: true }).getDevices()
).filter((d) => d.deviceClass === 6);

const device = await arg(
  "Choose a device",
  devices.map((device) => ({ name: device.productName, value: device }))
);

console.log({ device });

Dynamic/async import doesn't seem to help either

// Name: import-gopro

import "@johnlindquist/kit";

const { WebUSB } = await import("usb");

const devices = (
  await new WebUSB({ allowAllDevices: true }).getDevices()
).filter((d) => d.deviceClass === 6);

const device = await arg(
  "Choose a device",
  devices.map((device) => ({ name: device.productName, value: device }))
);

console.log({ device });

Hmm, this is working for me on last night's build: 1.32.2 (you can download it at scriptkit.com if you're not on the latest):

// Name: import-gopro

import "@johnlindquist/kit";

let { WebUSBDevice, getDeviceList }  = await npm("usb");

const devices = getDeviceList();

const device = await WebUSBDevice.createInstance(devices[0])

dev(device) // Show my webcam

Open import-gopro in Script Kit

Although the script you shared is throwing an "Error: initialize error: Error: Interface not found for address: 0" 🤷‍♂️ I have no idea why....

// Name: import-gopro

import "@johnlindquist/kit";

let { WebUSB }  = await npm("usb");

let customWebUSB = new WebUSB({
  // Bypass cheking for authorised devices
  allowAllDevices: true
});

// Throws an "Initialize error 🤷‍♂️"
let devices = await customWebUSB.getDevices();

I was able to make it work like this:

import "@johnlindquist/kit";
import type { WebUSB as WebUSBType } from "usb";
const { WebUSB } = await npm("usb");
const usb: WebUSBType = new WebUSB({ allowAllDevices: true });

kinda awkward but it works

[johnlindquist]

@joeflateau Here's what I recommend when typing npm

const { WebUSB }: typeof import("usb") = await npm("usb")

const usb = new WebUSB({
  allowAllDevices: true,
})

[joeflateau]

Nice!

[johnlindquist]

Oh, wait a sec, are you using the node-usb lib or the usb lib? The code is showing the usb lib, but the comment mentions node-usb...

[joeflateau]

Sorry for the confusion, I'm referring to the project published to npm as usb. (github repo is called node-usb)
