Version 2 will likely be available soon with a huge performance improvement. The API stays exactly as it is now. The only thing that changes is the WebRTC implementation. I switched from wrtc to node-datachannel. node-datachannel is much lighter and faster compared to wrtc.

You can test it today:

 npm i @geckos.io/client@dev @geckos.io/server@dev

CMake 3.15 or higher is required. You are running version 3.7.2

I get these errors installing on CentOS 7. I'm using nvm for my node install. Any ideas?

Do you have CMake >= 3.15?

jdspugh Mar 8, 2021

Yes

# cmake --version
cmake3 version 3.17.5

CMake suite maintained and supported by Kitware (kitware.com/cmake).

For others who want to know, it can be installed on CentOS 7 using:

# yum install cmake3
# sudo alternatives --install /usr/local/bin/cmake cmake /usr/bin/cmake 10 --slave /usr/local/bin/ctest ctest /usr/bin/ctest --slave /usr/local/bin/cpack cpack /usr/bin/cpack --slave /usr/local/bin/ccmake ccmake /usr/bin/ccmake --family cmake
# sudo alternatives --install /usr/local/bin/cmake cmake /usr/bin/cmake3 20 --slave /usr/local/bin/ctest ctest /usr/bin/ctest3 --slave /usr/local/bin/cpack cpack /usr/bin/cpack3 --slave /usr/local/bin/ccmake ccmake /usr/bin/ccmake3 --family cmake
# sudo alternatives --config cmake
There are 2 programs which provide 'cmake'.

  Selection    Command
-----------------------------------------------
   1           cmake (/usr/bin/cmake)
*+ 2           cmake (/usr/bin/cmake3)
Enter to keep the current selection[+], or type selection number: 2

I was using nvm to manage my nodejs versions. I switched to "n" and it gets past the npm command not found error now.

In version 2,also please implement the ability of client to run on node(useful for simulating multiple clients while developing game and also for stress-testing geckos.io server). If it is already supported ,please mention in the README . https://github.com/murat-dogan/node-datachannel/blob/master/examples/client-server/client.js provides an example which can be helpful to you for starting.

It seems cmake >= 3.15 is not the only dependency. I installed GnuTLS, libnettle, gmplib, and OpenSSL, with no luck.

My Dockerfile:

FROM node:14.15.0

When running npm i --save @geckos.io/server@dev I get this error:

I managed to get the installation working with this Dockerfile. However, The connection does not seem to be established between client/server

Edit: I#m using the same Dockerfile for both client and server, with a different port. I'm using --network=host when running the containers.

Another edit: There is no error message. The client does not seem to reach the "onConnect()" callback.

hi @yandeu
I am trying to update my project to version 2, but I am getting this error at runtime:

any idea what I'm doing wrong? The code worked fine with the older version.

Edit: NVM i solved it, it was actually parcel that was conflicting with a polyfill - in case it helps someone in the future.
