loader converter can convert various types of resources into JavaScript modules. In this way, any resource can be a module that Webpack can handle.
Intelligent parsingWebpack has an intelligent parser that can handle almost any third-party library, regardless of whether they are in the form of CommonJS, AMD or ordinary JS files. Even when loading dependencies, the dynamic expression require ("./templat
resources are incrementally loaded to the browser side, how to organize these fragmented code and resources in the development environment, and ensuring that they load and update quickly and gracefully on the browser side requires a modular system that is the ideal modular system that the front-end engineers have been exploring for years.This paper needs some basic concepts of Gulp and Webpack, and has a certain understanding of the use of Gulp and W

It ' s quite common to make a mistake while developing your webpack configuration. A simple typo can cost you hours of development time.

modularity of static resources has spawned a new module packager.I tried to extend the existing Module packager, but it failed to achieve all the goals.The objectives are as follows:1. Split the dependency tree into chunks to enable on-demand loading.2. Keep the initial load time low3. Each static resource can be a module4. Ability to set third-party libraries as modules5. Features that each part of the packager can be customized almost.6. Suitable for large projects.What's the difference betwe

The advantage of this is that the third-party library can be packaged as a CDN without being affected by the common.js that can be frequently changed.Use
