in the past two days, I was reading the official website of vue. At the beginning, I looked at the documentation of the instructions for the use of the vue.js file. I felt that it was easy to understand. But seeing Vue-router and Vuex made me look confused. What else does vue-cli do? there is also a need to install node.js. It was agreed that it would be simple to use the framework. It feels so complicated.
question:
what is vue-cli for?
do you have to use Vue-router and Vuex? Can"t I introduce vue.js directly into the page
