yarn 和 npm

  • yarn 速度更快（并行和离线缓存）
  • lock 版本 （与package-lock.json）

yarn.lock

  • 如package-lock.json 开发过程中不应删除重建 应当及时提交
  • yarn 过程根据yarn.lock的依赖树安装及拷贝package 且对与package.json不一致的依赖进行更新
  • 使用 yarn upgrade 根据package.json对依赖进行升级 并更新yarn.lock

yarn 和 yarn install

yarn install is used to install all dependencies for a project. This is most commonly used when you have just checked out code for a project, or when another developer on the project has added a new dependency that you need to pick up.
If you are used to using npm you might be expecting to use —save or —save-dev. These have been replaced by yarn add and yarn add —dev. For more information, see the yarn add documentation.

Running yarn with no command will run yarn install, passing through any provided flags.
