Answer 1

It’s troublesome to implement one by yourself. Fortunately, there are enough “giants’ shoulders” in the open source world to step on for us.

You can refer to other node open source libraries. For example, grunt and yo provide functions like 问答 in the project initialization function.

Let’s see how they achieve it?

• grunt: implemented through the prompt library, click the portal

• yo: Implemented through the Inquirer.js library, click on the portal

Attached is a screenshot of the yoinitialization project
