Then, create a directory on the VM where you wish to store/run the websocket. Sudo ln -s /usr/bin/nodejs /usr/local/bin/node Install Node/npm (node package manager) sudo apt-get install nodejs npm #install node/npm content from http and https sources is frowned upon), and in this case, the 'wss' protocol is preferred. In addition, if your site runs on an https connection, then the websocket also needs to be encrypted. ![]() The documentation – and it is excellent – for setting up a local client + server is already available in the 'ws' repository however, I found that figuring out a production-level/cloud VM setup required collating multiple guides. The simplest way to get real-time chat up and running was to use a Node package called 'ws' to set up a websocket-server (written in Javascript, of course), and then write a client in any language we wish to (in our case, Dart). ![]() ![]() Given the current state of the world, supporting features such as collaborative editing and real-time chat became almost essential to TunePad's long term success.Īll modern browsers support websockets and a lot of progress has been made since the time socket.io was the only option. The purpose of this guide is to help someone setup a secure websocket server on any Ubuntu VM (AWS/Linode/Digital Ocean/Azure etc.).
