Engineering of the front end
The main purpose of front-end engineering is to improve the development efficiency and code quality, increase the maintainability of the project and reduce the difficulty of the later update iteration.
componentization
Componentization is the breaking up of UI pages into different parts. A page is made up of a large component, which in turn contains multiple medium-sized components, which in turn can contain multiple small parts. Each component is a complete unit of HTML, CSS, and JS.
modular
Modular tools include Webpack
The canonical
Whether the directory structure of the project is reasonable, and whether there is a unified positioning management of the project resources.
Improve team collaboration and code quality through code specifications, naming conventions, and front-end interface data specifications.
