Creating a MonoRepo with NPM Workspaces

NPM Workspaces was introduced in NPM 7 and is a generic term that refers to the set of features in the npm CLI that provides support for managing multiple packages from your local filesystem, from within a singular top-level root package.

The first thing you need to do in order to create a monorepository is to create a root package.json file, which should contain the following code:

{
  "name": "web-creator",
  "private": true,
  "workspaces": [
    "packages/*"
  ]
}

We need to specify that web-creator will be private (only the root), and we need to specify the workspaces where our packages will live, which is on "packages/*"; the * means that we will include any directory that exists under the packages folder.
