yarn  workspace 开发示例

{
    "private": true,
    "workspaces": [
        "workspace-a",
        "workspace-b"
    ]
}

Note that the private: true is required! Workspaces are not meant to be published, so we’ve added this safety measure to make sure that nothing can accidentaly expose them.

After this file has been created, create two new subfolders named workspace-a and workspace-b. In each of them, create another package.json file with the following content:

{
    "name": "workspace-a",
    "version": "1.0.0",

    "dependencies": {
        "cross-env": "5.0.5"
    }
}

{
    "name": "workspace-b",
    "version": "1.0.0",

    "dependencies": {
        "cross-env": "5.0.5",
        "workspace-a": "1.0.0"
    }
}
