globalThis.XMLHttpRequest is not a constructor

I am trying to use wrangler deploy to deploy my app, but it keeps giving this error. I am not using XMLHttpRequest afaik. Dependencies:

"devDependencies": {
    "@types/express": "^4.17.20",
    "@types/node": "^20.8.7",
    "nodemon": "^3.0.1",
    "tsx": "^3.14.0",
    "typescript": "^5.2.2",
    "wrangler": "^3.14.0"
},
"dependencies": {
    "canvas": "^2.11.2",

Workers only support fetch, not XHR. You probably have a dependency using it. rollup-plugin-node-polyfills meowthinking

- that shouldn't be throwing it. It hasn't been updated for ~4 years. It sounds like you have some code which is trying to load the http NodeJS module.

I would assume express uses XHR/http then, do you know of any alternatives? They send interactions with my bot to my /interactions endpoint, after that I can handle it and respond Got the hono server working, but now publish is throwing a different error:

node_modules/@hono/node-server/dist/listener.js:25:30: ERROR: Could not resolve
  "node:stream/promises"

node_modules/@hono/node-server/dist/listener.js:25:30: ERROR: Could not resolve
  "node:stream/promises"

The package "node:stream/promises" wasn't found on the file system but is built into node. Are you trying to bundle for node? You can use "platform: 'node'" to do that, which will remove this error.

There is also this, but I don't know where to specify this option.

Can you show your imports in the Worker? There shoudn't be a @hono/node-server.

MrDiamond•8mo ago

Well I cant serve the server without it afaik Ok nvm, I just needed to export default app Uncaught TypeError: fs_1.default.readdirSync is not a function how much code do i need to replace??

kian•8mo ago

fs isn't available since Workers don't have a filesystem, there is no disk.

I switched to render so I don't have to deal with all these trade-offs
