Creating Socket Client Connections
So far in this chapter, weâve explored the server side of Node sockets. Here weâll write a client program in Node to receive JSON messages from our net-watcher-json-service program. Weâll start with a naive implementation, and then improve upon it through the rest of the chapter.
Open an editor and insert this:
