| net.createConnection(options[, connectionListener]) | A factory method, which returns a new 'net.Socket' and connects to the supplied address and port. |
| net.createConnection(path[, connectListener]) | Creates unix socket connection to path. The connectListener parameter will be added as an listener for the 'connect' event. A factory method which returns a new 'net.Socket'. |
| net.createConnection(port[, host][, connectListener]) | Creates a TCP connection to port on host. If host is omitted, 'localhost' will be assumed. The connectListener parameter will be added as an listener for the 'connect' event. Is a factory method which returns a new 'net.Socket'. |
| net.createServer([options][, connectionListener]) | Creates a new TCP server. The connectionListener argument is automatically set as a listener for the 'connection' event. |
| net.isIP(input) | Tests if input is an IP address. Returns 0 for invalid strings, returns 4 for IP version 4 addresses, and returns 6 for IP version 6 addresses. |
| net.isIPv4(input) | Returns true if input is a version 4 IP address, otherwise returns false. |
| net.isIPv6(input) | Returns true if input is a version 6 IP address, otherwise returns false. |
| new Buffer(buffer) | Copies the passed buffer data onto a new Buffer instance. |
| new Buffer(size) | Allocates a new buffer of size octets. Note, size must be no more than kMaxLength. Otherwise, a RangeError will be thrown here. |
| new Buffer(str[, encoding]) | Allocates a new buffer containing the given str. encoding defaults to 'utf8'. |
| new net.Socket([options]) | Construct a new socket object. |
| newListener | This event is emitted any time a listener is added. When this event is triggered, the listener may not yet have been added to the array of listeners for the event. |
| nextTick(callback) | Once the current event loop turn runs to completion, call the callback function. |
| on(event, listener) | Adds a listener to the end of the listeners array for the specified event. No checks are made to see if the listener has already been added. Multiple calls passing the same combination of event and listener will result in the listener being added multiple times. Returns emitter, so calls can be chained. |
| once(event, listener) | Adds a one time listener for the event. This listener is invoked only the next time the event is fired, after which it is removed. Returns emitter, so calls can be chained. |
| os.arch() | Returns the operating system CPU architecture. Possible values are "x64", "arm" and "ia32". |
| os.cpus() | Returns an array of objects containing information about each CPU/core installed: model, speed (in MHz), and times (an object containing the number of milliseconds the CPU/core spent in: user, nice, sys, idle, and irq). |
| os.endianness() | Returns the endianness of the CPU. Possible values are "BE" or "LE". |
| os.EOL | A constant defining the appropriate End-of-line marker for the operating system. |
| os.freemem() | Returns the amount of free system memory in bytes. |
| os.hostname() | Returns the hostname of the operating system. |
| os.loadavg() | Returns an array containing the 1, 5, and 15 minute load averages. |
| os.networkInterfaces() | Get a list of network interfaces. |
| os.platform() | Returns the operating system platform. |
| os.release() | Returns the operating system release. |
| os.tmpdir() | Returns the operating system's default directory for temp files. |
| os.totalmem() | Returns the total amount of system memory in bytes. |
| os.type() | Returns the operating system name. |
| os.uptime() | Returns the system uptime in seconds. |
| path.basename(p[, ext]) | Return the last portion of a path. Similar to the Unix basename command. |
| path.dirname(p) | Return the directory name of a path. Similar to the Unix dirname command. |
| path.extname(p) | Return the extension of the path, from the last '.' to end of string in the last portion of the path. If there is no '.' in the last portion of the path or the first character of it is '.', then it returns an empty string. |
| path.format(pathObject) | Returns a path string from an object, the opposite of path.parse above. |
| path.isAbsolute(path) | Determines whether path is an absolute path. An absolute path will always resolve to the same location, regardless of the working directory. |
| path.join([path1][, path2][, ...]) | Join all arguments together and normalize the resulting path. |
| path.normalize(p) | Normalize a string path, taking care of '..' and '.' parts. |
| path.parse(pathString) | Returns an object from a path string. |
| path.relative(from, to) | Solve the relative path from from to to. |
| path.resolve([from ...], to) | Resolves to to an absolute path. |
| removeAllListeners([event]) | Removes all listeners, or those of the specified event. It's not a good idea to remove listeners that were added elsewhere in the code, especially when it's on an emitter that you didn't create (e.g. sockets or file streams). Returns emitter, so calls can be chained. |
| removeListener | This event is emitted any time someone removes a listener. When this event is triggered, the listener may not yet have been removed from the array of listeners for the event. |
| removeListener(event, listener) | Remove a listener from the listener array for the specified event. Caution: changes array indices in the listener array behind the listener. removeListener will remove, at most, one instance of a listener from the listener array. If any single listener has been added multiple times to the listener array for the specified event, then removeListener must be called multiple times to remove each instance. Returns emitter, so calls can be chained. |
| server.address() | Returns the bound address, the address family name and port of the server as reported by the operating system. |
| server.close([callback]) | finally closed when all connections are ended and the server emits a 'close' event. |
| server.getConnections(callback) | 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. |
| server.listen(handle[, callback]) | The handle object can be set to either a server or socket (anything with an underlying _handle member), or a {fd: |
| server.listen(options[, callback]) | The port, host, and backlog properties of options, as well as the optional callback function, behave as they do on a call to server.listen(port, [host], [backlog], [callback]) . Alternatively, the path option can be used to specify a UNIX socket. |
| server.listen(path[, callback]) | Start a local socket server listening for connections on the given path. |
| server.listen(port[, host][, backlog][, callback]) | Begin accepting connections on the specified port and host. If the host is omitted, the server will accept connections directed to any IPv4 address (INADDR_ANY). A port value of zero will assign a random port. |
| server.ref() | Opposite of unref, calling ref on a previously unrefd server will not let the program exit if it's the only server left (the default behavior). If the server is refd calling ref again will have no effect. |
| server.unref() | 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 unrefd calling unref again will have no effect. |
| setgid(id) | Sets the group identity of the process. (See setgid(2).) This accepts either a numerical ID or a groupname string. If a groupname is specified, this method blocks while resolving it to a numerical ID.This function is only available on POSIX platforms (i.e. not Windows, Android). |
| setgroups(groups) | Sets the supplementary group IDs. This is a privileged operation, meaning you need to be root or have the CAP_SETGID capability.This function is only available on POSIX platforms (i.e. not Windows, Android). |
| setMaxListeners(n) | By default EventEmitters will print a warning if more than 10 listeners are added for a particular event. This is a useful default which helps finding memory leaks. Obviously not all Emitters should be limited to 10. This function allows that to be increased. Set to zero for unlimited. |
| setuid(id) | Sets the user identity of the process. (See setgid(2).) This accepts either a numerical ID or a username string. If a username is specified, this method blocks while resolving it to a numerical ID.This function is only available on POSIX platforms (i.e. not Windows, Android). |
| socket.address() | Returns the bound address, the address family name and port of the socket as reported by the operating system. Returns an object with three properties, e.g. { port: 12346, family: 'IPv4', address: '127.0.0.1' }. |
| socket.connect(path[, connectListener]) | Opens the connection for a given socket. If port and host are given, then the socket will be opened as a TCP socket, if host is omitted, localhost will be assumed. If a path is given, the socket will be opened as a unix socket to that path. |
| socket.connect(port[, host][, connectListener]) | Opens the connection for a given socket. If port and host are given, then the socket will be opened as a TCP socket, if host is omitted, localhost will be assumed. If a path is given, the socket will be opened as a unix socket to that path. |
| socket.destroy() | Ensures that no more I/O activity happens on this socket. Only necessary in case of errors (parse error or so). |
| socket.end([data][, encoding]) | Half-closes the socket. i.e., it sends a FIN packet. It is possible the server will still send some data. |
| socket.pause() | Pauses the reading of data. That is, 'data' events will not be emitted. Useful to throttle back an upload. |
| socket.ref() | Opposite of unref, calling ref on a previously unrefd socket will not let the program exit if it's the only socket left (the default behavior). If the socket is refd calling ref again will have no effect. |
| socket.resume() | Resumes reading after a call to pause(). |
| socket.setEncoding([encoding]) | Set the encoding for the socket as a Readable Stream. |
| socket.setKeepAlive([enable][, initialDelay]) | Enable/disable keep-alive functionality, and optionally set the initial delay before the first keepalive probe is sent on an idle socket. enable defaults to false. |
| socket.setNoDelay([noDelay]) | Disables the Nagle algorithm. By default TCP connections use the Nagle algorithm, they buffer data before sending it off. Setting true for noDelay will immediately fire off data each time socket.write() is called. noDelay defaults to true. |
| socket.setTimeout(timeout[, callback]) | Sets the socket to timeout after timeout milliseconds of inactivity on the socket. By default net.Socket do not have a timeout. |
| socket.unref() | Calling unref on a socket will allow the program to exit if this is the only active socket in the event system. If the socket is already unrefd calling unref again will have no effect. |
| socket.write(data[, encoding][, callback]) | Sends data on the socket. The second parameter specifies the encoding in the case of a string--it defaults to UTF8 encoding. |
| umask([mask]) | Sets or reads the process's file mode creation mask. Child processes inherit the mask from the parent process. Returns the old mask if mask argument is given, otherwise returns the current mask. |
| uptime() | Number of seconds Node has been running. |
