A Profile
Vue CLI is a complete system based on Vue.js rapid development, there are several independent parts.
. 1 the CLI ( @vue/cli) is a global installation package npm, provided in the terminal vue command. (Vue create, vue serve, etc.)
2 CLI service ( @vue/cli-service) is a development environment dependent. It is a npm package locally installed at each @vue/cliproject you create. CLI service is built on top of webpack and webpack-dev-server's.
3 CLI plug-in is optional functionality to your Vue project npm package, such as Babel / TypeScript translation, ESLint integration, unit testing and end-to-end testing.
(For example, when you create a project manual, Vue Cli 3 adds @ vue / cli-plugin-babel, @ vue / cli-plugin-eslint, @ vue / cli-plugin-unit-jest and other plug-ins)
