Introduction, installation and use of nodejs yarn

1 Introduction

Front-end development often needs to work with the back-end at the same time. Without the back-end, server communication and data acquisition for page rendering cannot be performed. The Node.js server written in Javascript, for front-end developers, can avoid the cost of learning server scripting language, and can build a complete and efficient Web service in a short time. NPM (Node Package Manager) came into being as a dependency package manager of Node.js, and YARN was designed and developed for some of the not-so-good parts of NPM.
