使用 lerna 和 yarn 构建 monorepo 项目

When coupled together, Lerna and Yarn Workspaces can ease and optimize the management of working with multi-package repositories.
Lerna makes versioning and publishing packages to an NPM Org a painless experience by providing helpful utility commands for handling the execution of tasks across multiple packages.
Yarn Workspaces manages our dependencies. Rather than having multiple node_modules directories, it intelligently optimizes the installing of dependencies together and allows for the cross-linking of dependencies in a monorepo. Yarn Workspaces provide tools, like Lerna, the low-level primitives it needs to manage multi-package repositories.

# lerna.json
"npmClient": "yarn",
"useWorkspaces": true,

"workspaces": ["packages/*"]

lerna create @hello-js/saysomething

lerna create @hello-js/sayhelloworld

lerna add @hello-js/saysomething --scope @hello-js/sayhelloworld

yarn workspace @hello-js/sayhelloworld start

yarn run demo:start
