prosemirror-dat demo broken?

[mgielda]

The prosemirror-dat demo does not work for me - during npm install I get:

[419] ./prosemirror.js + 62 modules 919 KiB {0} [built]
      | ./prosemirror.js 2.04 KiB [built]
      | ./schema.js 5.74 KiB [built]
      |     + 61 hidden modules
    + 409 hidden modules

Also, looking at package.json I see that the HTML filename is wrong, i.e. it says prosemirror.html but the file in the example is prosemirror-dat.html. I assume the example is not being tested / is obsolete?

[mgielda]

Ah, I see, it's definitely not obsolete, on the contrary it's brand-new ;)

Anyhow, forgot to day - thank you so much for these demos, super helpful. So just trying to be helpful by letting you know this one does not work, probably something small...

[dmonad]

It's sometimes hard to keep all these projects in-sync. I fixed the filename issue. But I can't reproduce the other issue.

In a fresh clone of yjs-demos I did: cd prosemirror-dat && npm i && npm start

If this still doesn't work for you, can you please report the npm version and the node version?

Hi, im having the same problem.

Thank you.

Hi @gremloon, I just installed node v12.18.1 with npm 6.14.5. Then I did the following.

git clone git@github.com:yjs/yjs-demos.git
cd yjs-demos/prosemirror-dat
npm i
npm start // working 🎉

And it is working for me. What am I doing differently?

I know it is painful to define exactly what you are doing. But I really can't debug this issue if I can't reproduce it. This is why the new Bug Forms now require you to fill out exactly what you are doing.

I also get the first error message:

This is normal. This is a problem with the native bindings for dat. Nothing that concerns Yjs.

I just can't reproduce the second error message.
