Readable boolean Allow reads on the socket when an fd is passed, otherwise ignored. Writable boolean Allow writes on the socket when an fd is passed, otherwise ignored. Returns: cket The newly created socket can be either a tcp socket or a streaming ipc endpoint, depending on what it connect. Event: 'close' Added in:.1.90 hadError boolean true if the socket had a transmission error. Emitted once the socket is fully closed. The argument hadError is a boolean which says if the socket was closed due to a transmission error. Event: 'connect' Added in:.1.90 Emitted when a socket connection is successfully established.

A cket is also a duplex stream, so it can paper be both readable and writable, and it is also an eventEmitter. A cket can be created by the user and used directly to interact with a server. For example, it is returned by eateConnection, so the user can use it to talk to the server. It can also be created by node. Js and passed to the user when a connection is received. For example, it is passed to the listeners of essay a 'connection' event emitted on a rver, so the user can use it to interact with the client. New cket(options) Added in:.3.4 Creates a new socket object. Options Object available options are: fd number If specified, wrap around an existing socket with the given file descriptor, otherwise a new socket will be created. AllowHalfOpen boolean Indicates whether half-opened tcp connections are allowed. See eateServer and the 'end' event for details.

Stening Added in:.7.0 boolean Indicates whether or not the server is listening for connections. XConnections Added in:.2.0 Set this mini property to reject connections when the server's connection count gets high. It is not recommended to use this option once a socket has been sent to a child with child_rk. F Added in:.9.1 Opposite of unref calling ref on a previously unrefed server will not let the program exit if it's the only server left (the default behavior). If the server is refed calling ref again will have no effect. Unref Added in:.9.1 Calling unref on a server will allow the program to exit if this is the only active server in the event system. If the server is already unrefed calling unref again will have no effect. Class: cket Added in:.3.4 This class is an abstraction of a tcp socket or a streaming ipc endpoint (uses named pipes on Windows, and unix domain sockets otherwise).

Handling - a complete guide

Sten( host: 'localhost plan port: 80, exclusive: true starting an ipc server as root may cause the server path to be inaccessible for unprivileged users. Using readableAll and writableAll will make the server accessible for all users. Sten(path, backlog, callback) Added in:.1.90 Start an ipc server listening for connections on the given path. Sten(port, host, backlog, callback) Added in:.1.90 Start a tcp server listening for connections on the given port and host. If port is omitted or is 0, the operating system will assign an arbitrary unused port, which can be retrieved by using dress. Port after the 'listening' event has been emitted. If host is omitted, the server will accept connections on the unspecified ipv6 address when ipv6 is available, or the unspecified ipv4 address otherwise. In most operating systems, listening to the unspecified ipv6 address may cause the rver to also listen on the unspecified ipv4 address.

Listening on a file descriptor is not supported on Windows. Sten(options, callback) Added in:.11.14 If port is specified, it behaves the same as sten(port, host, backlog, callback). Otherwise, if path is specified, it behaves the same as sten(path, backlog, callback). If none of them is specified, an error will be thrown. If exclusive is false (default then cluster workers will use the same underlying handle, allowing connection handling duties to be shared. When exclusive is true, the handle is not shared, and attempted port sharing results in an error. An example which listens on an exclusive port is shown below.

The actual length will be determined by the nurse os through sysctl settings such resume as tcp_max_syn_backlog and somaxconn on Linux. The default value of this parameter is 511 (not 512). All cket are set to so_reuseaddr (see socket(7) for details). The sten method can be called again if and only if there was an error during the first sten call or ose has been called. Otherwise, an err_server_already_listen error will be thrown. One of the most common errors raised when listening is eaddrinuse. This happens when another server is already listening on the requested port/path/handle.

One way to handle this would be to retry after a certain amount of time: server. On error (e) if (de 'eaddrinuse console. Log Address in use, retrying. setTimeout ose sten(port, host, 1000 sten(handle, backlog, callback) Added in:.5.10 Start a server listening for connections on a given handle that has already been bound to a port, a unix domain socket, or a windows named pipe. The handle object can be either a server, a socket (anything with an underlying _handle member or an object with an fd member that is a valid file descriptor.

Nnections Added in:.2.0Deprecated since:.9.7 The number of concurrent connections on the server. This becomes null when sending a socket to a child with child_rk. To poll forks and get current number of active connections use asynchronous tConnections instead. TConnections(callback) Added in:.9.7 Asynchronously get the number of concurrent connections on the server. Works when sockets were sent to forks.


Callback should take two arguments err and count. Sten Start a server listening for connections. A rver can be a tcp or an ipc server depending on what it listens. Possible signatures: sten(handle, backlog, callback) sten(options, callback) sten(path, backlog, callback) for ipc servers sten(port, host, backlog, callback) for tcp servers This function is asynchronous. When the server starts listening, the 'listening' event will be emitted. The last parameter callback will be added as a listener for the 'listening' event. All listen methods can take a backlog parameter to specify the maximum length of the queue of pending connections.

For a server listening on a pipe or unix domain socket, the name is returned as a string. Example: const server eateServer(socket) socket. End goodbyen ).on error (err) / handle errors here throw err; / grab an arbitrary unused port. Log opened server on dress don't call dress until the 'listening' event has been emitted. Ose(callback) Added in:.1.90 Stops the server from accepting new connections and keeps existing connections. This function is asynchronous, the server is finally closed when all connections are ended and the server emits a 'close' event. The writing optional callback will be called once the 'close' event occurs. Unlike that event, it will be called with an Error as its only argument if the server was not open when it was closed.

Rver is an eventEmitter with the following events: event: 'close' Added in:.5.0 Emitted when the server closes. Note that if connections exist, this event is not emitted until all connections are ended. Event: 'connection' Added in:.1.90 paperweight Emitted when a new connection is made. Socket is an instance of cket. Event: 'error' Added in:.1.90 Emitted when an error occurs. Unlike cket, the 'close' event will not be emitted directly following this event unless ose is manually called. See the example in discussion of sten. Event: 'listening' Added in:.1.90 Emitted when the server has been bound after calling sten. Dress Added in:.1.90 Returns the bound address, the address family name, and port of the server as reported by the operating system if listening on an ip socket (useful to find which port was assigned when getting an os-assigned address port: 12346, family.

are removed when the last reference to them is closed. Unlike unix domain sockets, windows will close and remove the pipe when the owning process exits. Javascript string escaping requires paths to be specified with extra backslash escaping such as: sten( in? Cwd 'myctl Class: rver Added in:.1.90 This class is used to create a tcp or ipc server. New rver(options, connectionListener) see eateServer(options, connectionListener).

The path is subject to the same naming conventions and permissions checks as would be done on file creation. If the unix domain socket (that is visible as a file system path) is created and used in conjunction with one of Node. Js' api abstractions such as eateServer, it will be unlinked as part of ose. On the other hand, if it is created and used outside of these abstractions, the user will need to manually remove. The same applies when the path was created by a node. Js api but the program crashes abruptly. In short, a unix domain socket once successfully created will be visible in the filesystem, and will persist until unlinked. On Windows, the local domain is implemented using a named pipe.

Stability: 2 - stable, the net module provides an asynchronous network api for creating stream-based. Tcp or, ipc servers ( eateServer ) and clients ( eateConnection friend ). It can be accessed using: const net require net ipc support the net module supports ipc with named pipes on Windows, and unix domain sockets on other operating systems. Identifying paths for ipc connections nnect, eateConnection, sten and nnect take a path parameter to identify ipc endpoints. On unix, the local domain is also known as the unix domain. The path is a filesystem pathname. It gets truncated to sizeof(sockaddr_n_path) - 1, which varies on different operating system between 91 and 107 bytes. The typical values are 107 on Linux and 103 on macOS.
