Analyzes the callback and code design modes in Node. js asynchronous programming, and node. js design modes The biggest selling point of NodeJS is the event mechanism and asynchronous IO, which is not transparent to developers. Developers need to write code in asynchronous mode to use this selling point, which has also

This article mainly introduces Node. the event-driven programming in js is explained in detail. This article mainly describes theoretical knowledge, such as what is event-driven programming, What Is closures, and how closures help asynchronous programming, if you need it, you can refer to the traditional programming model.

Node. js public platform development tutorial, node. js public How can nodejs be used to develop public platforms? Let's not talk about anything more. First, let's briefly introduce the basic principles of the public platform. The server is equivalent to a forwarding server. A terminal (such as a mobile phone or tablet

This article mainly introduces Node. in js, the event transmitter mode is used to implement event binding. This article also explains the basic knowledge of callback mode, transmitter mode, and event type. For more information, see Node, many objects launch events. For example, a TCP server will launch a "connect" event whenever a client requests a connection. Fo

It is easy to manually run the Node project on a computer, nodexx. javascript is done. If you want to run the Node project in the background, you cannot directly use the node command. However, it is easy to install the forever package. However, if a Node project is built on a remote server and cannot be started on its

This article mainly introduces Custom Event instances in node. js. A simple example. For more information, see the EventEmitter that inherits events, then you can register the event through the on; emit triggers the event and removeListener removes the event. A simple example is as follows: Var util = require ('util'); var Et = require ('events '). eventEmitter; function Ticker () {var self = this; s

device grantpt and set the permission to unlockpt from the device to unlock the corresponding master device to get the read/write from the device name (like/dev/pts/123) from the device, perform operations Therefore, a better pty library is encapsulated. You can use only one forkpty function to implement all the above functions. Write a node c ++ extension module and use the pty library to implement a terminal for Executing command lines from the dev
