Quickly test your socket.io backend apps
Development Environment
VS Code
Use Remote Containers: Reopen in Container. This should use .devcontainer/devcontainer.json configuration to start up a development environment and open your workspace.
Start a local socket.io server on 8080 with cd dummy-server && npm install, then npm run dev.
You can start the client app locally with cd react-client-tool && npm install, then yarn start.
