Using packages

In order to use a package we should add it as a dependency on the package.json file. The yarn command is:

yarn workspace @application/<Application Name> add @packages/<Package Name>@1.0.0

Commands

Boostrap

Bootstrap the packages in the current Lerna repo. Installs all of their dependencies and links any cross-dependencies. The flag --use-workspaces Enables integration with Yarn Workspaces

$ yarn bootstrap

Build

lerna exec will take any command and run it over all of the different packages. This command instructs Babel to run in parallel over every package, pulling from the /src folder and compiling into the /lib folder. We don’t want to include any stories in the compiled output. Using --root-mode upward is the special sauce to using Yarn workspaces. This tells Babel the node_modules are located in the root instead of nested inside each of the individual packages. This prevents each package from having the same node_modules and extracts them up to the root.

$ yarn build
