Environment configuration of Angular CLI
Foreword: Angular8 develops Pinduoduo webapp from basic to actual combat
Prepare one: Angular CLI environment configuration
step: node -> NPM / CNPM -> Angular CLI
Install node.js
1. Log in to the Node.js page: https://nodejs.org/en/
2. Download LTS (the maintenance time is relatively long)
Note: The purpose of installing node.js is to use npm to manage the packages that the project depends on
The role and difference between npm and cnpm
npm roleFor details, see: Summary of common functions of npm .
Personal understanding: When doing a huge project, you need a lot of packages, such as three packages abc, package a needs to depend on more packages, package b needs to depend on more packages, and package c needs to depend on more packages. Such a layer is nested one after another, which will cause trouble in the later operation of the project and version upgrade, but you can use npm to download the corresponding package to make it easier to manage later.
cnpmThe functions of cnpm and npm are similar. Due to the network environment (slow network speed or slow download, etc.), cnpm is used as an alternative package management tool.
