The net module gives us access to lower-level socket systems and even to local InterProcess Communication (IPC) schemes that we can use. IPC schemes are communication strategies that allow us to talk between processes. Processes don't share memory, which means that we have to communicate through other means. In Node.js, this usually means three different strategies, and they all depend on how quickly and how tightly coupled we want the systems to be. These three strategies are as follows:
- Unnamed pipes
- Named pipes/local domain sockets
- TCP/UDP sockets
First, we have unnamed pipes. These are one-way communication systems that are not seen on the filesystem and are shared between a parent and a child process. This means that a ...
