- * Template Socket.IO Use Middleware for uibuilder.
- *
- * NOTES & WARNINGS:
- * 1) This function is called when a client sends a "packet" if data to the server.
- * 2) Failing to either return or call `next()` will mean that your clients will never be able to get responses.
- * 3) An error in this function will probably cause Node-RED to fail to start at all.
- * 4) You have to restart Node-RED if you change this file.
- * 5) If you call `next( new Error('blah') )` The error is sent back to the client and further proessing of the incoming msg stops.
- *
- * Allows you to process incoming data from clients.
- *
- * @see also https://cheatsheetseries.owasp.org/cheatsheets/HTML5_Security_Cheat_Sheet.html#websocket-implementation-hints
- *
- * @param {*} msg The msg send by a client (Socket.IO calls it a "packet")
- * @param {function} next The callback to hand off to the next middleware
