I. Introduction to Vue.js

Vue (pronounced/vju $>/, similar to view) is a progressive framework for building user interfaces. Unlike other large frameworks, Vue is designed to be applied layer by layer from the bottom up. Vue's core library focuses only on the view layer, which is not only easy to get started, but also easy to integrate with third-party libraries or existing projects. Vue, on the other hand, is perfectly capable of providing drivers for complex single-page applications when used in conjunction with modern toolchains and various supporting libraries.

Note: Everyone must put npm and cnpm in the same directory; mine is in

"C:\Program Files\nodejs\node_global", everyone remember to switch to the installation directory if there is a problem, and put npm and cnpm in the same directory to avoid errors.
