yjs throws error when using @remix-run/dev 1.16.0

[anton-g]

What version of Remix are you using?

1.16.0

Are all your remix dependencies & dev-dependencies using the same version?

• Yes

Steps to Reproduce

Version 1.16.0 of @remix-run/dev breaks yjs. It works fine for 1.15.0 of @remix-run/dev.

I didn't know how to add a test for this specific case, but here's a CodeSandbox with reproduction: https://codesandbox.io/p/github/anton-g/remix-yjs-error/main

Steps to recreate from scratch:

➜ npx create-remix@latest
? Where would you like to create your app? ./yjs-example
? What type of app do you want to create? Just the basics
? Where do you want to deploy? Choose Remix App Server if you're unsure; it's easy to change deployment
targets. Remix App Server
? TypeScript or JavaScript? TypeScript
? Do you want me to run `npm install`? Yes

➜ npm i yjs

Add the following to the top of _index.js:

import * as Y from 'yjs'

const ydoc = new Y.Doc()

Run the app (npm run dev) and refresh the page.

Expected Behavior

New yjs Doc created successfully on page load.

Actual Behavior

Client crashes with error:

caught TypeError: Cannot read properties of undefined (reading 'isTTY')

@anton-g what future flags do you have enabled in remix.config.js?

[pcattori]

Might be related to #6259

[anton-g]

@anton-g what future flags do you have enabled in remix.config.js?

Just the defaults from create-remix:

  future: {
    v2_errorBoundary: true,
    v2_meta: true,
    v2_normalizeFormMethod: true,
    v2_routeConvention: true,
  },

Turning them off doesn't seem to make a difference.

We just published version 1.17.1-pre.0 which includes #6562 (a possible fix). If you'd like to take it for a test run please try it out and let us know what you think!

@anton-g Closing this as I can't reproduce this locally (tried with 1.15, 1.16 & 1.17) & the CodeSandbox you linked is working fine as well

[anton-g]

@MichaelDeBoey Tried with 1.17.1-pre.0 and seems to be working now! Great job! 🙌

[MichaelDeBoey]

@anton-g to be clear: when trying to reproduce this, it was already working in 1.15
