commonjs

small pieces that can work independently. You can then assemble or reorganize these blocks of code (like Lego) and create a variety of different applications from the same set of modules.Since the module is very useful, there have been several attempts to add module functionality to JavaScript in history. Today, two modular systems are being used on a wide scale. CommonJS (CJS) is used in the history of node. js. The ESM (EcmaScript module) is an upd

Module specification of COMMONJS The relationship between node and browser, as well as the organization of the COMMONJS, the ECMAScriptNode uses COMMONJS's modules specification to realize a set of modular system, so first look at the COMMONJS module specification.Commonjs The module definition is very simple, mainly divided into module reference, module definit

modular specifications have been introduced to address the need for asynchronous, modular programming on the browser side, and the core principle is to load modules asynchronously by dynamically loading script and event snooping; __ AMD and CMD are the most representative of the two works corresponding to Require.js and Sea.js, the main difference is the time to rely on the declaration and dependency loading, where require.js by default in the declaration, sea.js respected lazy loading and on-d

I previously in the "Front end of the environment from the beginning to give up" this article spit, Webpack can write COMMONJS format require synchronization syntax, can write the AMD format require callback syntax, There is also a require.ensure, and webpack own definition of require.include, plus ES6 import grammar, so many will not confuse people. This article will be to comb the characteristics of these require, and in what scenarios are used.COMM

Use require to load jslite, Zepto, and jquery methods, which are the same type of libraries so they are loaded, and here is an instance.Requirejs Reference instance methodThe goal of Requirejs is to encourage the modularity of code, which uses a script loading step that differs from the traditional Extend-jslite.jsDefine ([' Lib/jslite '], function (a) {"Use strict";Window. Jslite = JsliteIf ' $ ' or ' jQuery ' isn't yet defined, point them to ' jslite '' $ ' in window | | (window.$ = jslite)' J

This article mainly introduces Node. module mechanism learning notes in js. This article describes CommonJS module specifications, Node module implementation process, module call stack, packages, and NPM. For more information, see Javascript, no one once considered it a programming language. In the Web 1.0 era, this scripting language is mainly used for Form Verification and webpage special effects. It was not until the Web 2.0 era that front-end engi

This article mainly introduces require. js in-depth understanding, require. js features. This article describes require. javaScript and CommonJS are compatible, CDN rollback, cyclic dependency, BaseUrl, and JSONP. For more information, see Require. js is my favorite Javascript programming method. It can reduce code to zero and facilitate management. The Require. js Optimizer can help us to scatter a large application into multiple small applications,

"Cyclic loading" (circular dependency) means that the execution of a script relies on the B script, while the execution of the B script relies on a script. A.js var b = require (' B '); B.js var a = require (' a '); In general, "cyclic loading" means strong coupling, which, if poorly handled, can also result in recursive loading that prevents the program from executing and should therefore be avoided. But in fact, this is very difficult to avoid, especially the complex dependencie

Require. js: a deep understanding of require. js features Now, Require. js is my favorite Javascript programming method. It can reduce code to zero and facilitate management. The Require. js Optimizer can help us to scatter a large application into multiple small applications, connect them through dependencies, and finally combine them during compilation and packaging. These reasons prompted us to use require. js. So, let's take a look at the awesome features of require. js! Compatible with

line, the entire product from scratch, are to be controlled by the pipeline, in the assembly line we can manage the product." ”In addition, Gulp is built through a task for the entire development process.WebpackWebpack is now the most popular modular management and packaging tool for front-end resources. It can package many loose modules according to dependencies and rules into front-end resources that meet the deployment of the production environment. You can also code-separate modules that ar

Webpack can write the COMMONJS format of the Require synchronization syntax, you can write the require callback syntax in AMD format, There is also a require.ensure, and webpack own definition of require.include, plus ES6 import grammar, so many will not confuse people.
