Module) Stability: 5-locked Node has a simple module loading mechanism. The files and modules in node correspond one to one. For example, foo. js loads the circle. js module in the same

node. JS has built-in cluster functionality under the v0.6.0 version, as a cluster module for multi-core processing of nodejs, and easier scripting for a load-balanced cluster.The script references the other person's material, builds a server.js (because the virtual machine

requires you to explicitly invoke HTTP. The Clientrequest.end () method indicates that the data has been sent. Whenever Clientrequest.write () is called, the data is immediately uploaded (not cached), but the server will not respond to your data request before the Clientrequest.end () call. You can bind the data event of a stream with clientrequest.write () so that it can be sent to the server in the form of a stream. This can be a good idea, for example, when you need to send a file on your ha

This article mainly introduces the simple getting started course of Nodejs (1): module mechanism. This article describes the basic knowledge of the module, module loading, and Package content, if you need it, you can refer to the JavaScript specification (ECMAScript) without defining a complete set of standard libraries that can be applied to most programs. Commo

Let's go to the manual to see:It was clearly written to return an object.Then look at the Util module,Nonsense no oh more say, first a little bit of code:/** * Created by Leigood on 2016/8/13.*/varHTTP = require (' http ');varurl = require (' URL '));varUtil = require (' util '));varServer = Http.createserver (function(req,res) {Res.writehead (200,{"Content-type": "Text/plain"});//Plain, let him format the output of the dataRes.write (Util.inspect (Ur

empty.You can also write a string to a buffer that already exists. Buffer.write () writes the string to the location specified in buffer. If there is enough space at the beginning of the specified buffer, the entire string will be written. Otherwise, the tail of the string is truncated so that its size can be placed in buffer. In both cases, buffer.write () returns a number that indicates how many bytes were successfully written. For UTF-8 strings, if a full character cannot be written to buffe

This article mainly introduces Node. js module loading details. This article describes how to load core modules, file modules, directory modules, and file Loading modules, for more information, see JavaScript, one of the most frequently used programming languages in the world. It is a common language in the Web world and used by all browsers. JavaScript was born

exports is the property of the modules. In node, a file is a module that mounts the method as a property on the exports object to define how the export will be exported:Math.jsExports.add = function () {var sum = 0, i = 0, args = arguments, L = args.length;while (I return sum;};In another file, after we introduce the module through the Require () method, we can

refers to a Non-core module and is not a path-type identifier. It is a special kind of file module, which may be a file or package form. This type of module lookup is the most time-consuming and the slowest in all ways.2). File positioningFrom the optimization strategy of cache loading, the process of path analysis, file location and compile execution is not nee

As mentioned above, the command line of NodeJS and the "Hello, World" of the Web version are mentioned ". The command line directly executes the hello. js file, and the requirehttp module is required for the Web version. The http module is provided by NodeJS itself. We know that each module corresponds to a

When it comes to components, JavaScript does not have this feature. Many functions of Javascript in the past were implemented by different vendors. Components have the following features: . JavaScript does not have a module system. There is no native support for confined scope or dependency management. . JavaScript does not have a standard library. There are no file system APIs in the core library, but these will be available after html5 :). . JavaScr

interface, such as Web server or database. JavaScript does not have a package management system. Dependencies cannot be loaded and installed automatically. Hence the advent of the COMMONJS (http://www.commonjs.org) specification, which aims to build a JavaScript ecosystem that includes Web servers, desktops, command-line tools, and browsers. COMMONJS has developed some specifications to address these issues, and node.
