 "desc": "<a href=\"#net_net_connect\"><code>net.connect()</code></a>, <a href=\"#net_net_createconnection\"><code>net.createConnection()</code></a>, <a href=\"#net_server_listen\"><code>server.listen()</code></a> and\n<a href=\"#net_socket_connect\"><code>socket.connect()</code></a> take a <code>path</code> parameter to identify IPC endpoints.\nOn Unix, the local domain is also known as the Unix domain. The path is a\nfilesystem pathname. It gets truncated to an OS-dependent length of\n<code>sizeof(sockaddr_un.sun_path) - 1</code>. Typical values are 107 bytes on Linux and\n103 bytes on macOS. If a Node.js API abstraction creates the Unix domain socket,\nit will unlink the Unix domain socket as well. For example,\n<a href=\"#net_net_createserver_options_connectionlistener\"><code>net.createServer()</code></a> may create a Unix domain socket and\n<a href=\"#net_server_close_callback\"><code>server.close()</code></a> will unlink it. But if a user creates the Unix domain\nsocket outside of these abstractions, the user will need to remove it. The same\napplies when a Node.js API creates a Unix domain socket but the program then\ncrashes. In short, a Unix domain socket will be visible in the filesystem and\nwill persist until unlinked.\nOn Windows, the local domain is implemented using a named pipe. The path must\nrefer to an entry in <code>\\\\?\\pipe\\</code> or <code>\\\\.\\pipe\\</code>. Any characters are permitted,\nbut the latter may do some processing of pipe names, such as resolving <code>..</code>\nsequences. Despite how it might look, the pipe namespace is flat. Pipes will\nnot persist. They are removed when the last reference to them is closed.\nUnlike Unix domain sockets, Windows will close and remove the pipe when the\nowning process exits.\nJavaScript string escaping requires paths to be specified with extra backslash\nescaping such as:\n<pre><code class=\"language-js\">net.createServer().listen(\n path.join('\\\\\\\\?\\\\pipe', process.cwd(), 'myctl'));\n</code></pre>",
