method Socket.prototype.ref

Usage in Deno

import { Socket } from "node:net";



Socket.prototype.ref(): this

Opposite of unref(), calling ref() on a previously unrefed socket will not let the program exit if it's the only socket left (the default behavior). If the socket is refed calling ref again will have no effect.

Return Type

this

The socket itself.
