I am trying to run the private chat example following the readme instructions but I see this error trying to install the client side

npm ERR! code ERESOLVE

I am using Node 18.15 and NPM 9.5 that are the current LTS versions for both. How to fix?

On the server side trying to run I see:

Node.js v18.15.0

      throw er; // Unhandled 'error' event
      ^

}

this is just an example since it keeps looping on this kind of error

I will take a look at into this issue 👍 !

[pawanmkr]

can you provide link to the instructions?

[haneenmahd]

I could reproduce several issues in the vue project. They are

• outdated npm packages
• not supported to the new ssl provider after node v16
• outdated eslint config

On the server side, it fails to connect to the port 6379 because you aren't running a Redis server. You have run it using the command redis-server. See Stackoverflow

Thanks @haneenmahd for the "not supported ..... after node v16" part. I don't have much time and wants to learn about private messaging. Didn't know about the error's cause. I can use it with 16 lts right now 👍 I hope going to fix in the near future.

[haneenmahd]

I'm gonna take a look into the example and let me do what I can do with it 😊!

[haneenmahd]

I have opened up a new PR fixing the docs and legacy provider bug. Hope it helps future devs checking out the example. FYI, you can fix the dependency installation by adding a -legacy-peer-deps flag while installing.

I've bumped the dependencies in cbf0362, it should now work properly on Node.js 18. Could you please check?

[haneenmahd]

@darrachequesne yes, it does work now! the dependencies are up-to-date.

[darrachequesne]

@haneenmahd awesome, thanks for the feedback 👍

I'm closing this now, please reopen if needed.
