Configuration templates?

[jonathanconway]

Note: Similar goals might be achieved with this feature: Support for a workspace.js file. #6511.

I'm currently building a monorepo which has many apps.

This results in a lot of duplication in workspaces.json, as each app has pretty much the same configuration. It's tedious having to maintain this massive file and do find-replace operations every time I want to add a new application.

Could we consider some kind of templated configuration?

Maybe we could support a separate file called workspace.templates.json or similar, where we can define named templates, with mustache-style tags allowing values to be interpolated, and providing, say, an app object, which has info about the app being configured.

E.g.

{
  "my-template": {
    "projectType": "application",
    "root": "apps/{{ app.name }}",
    "sourceRoot": "apps/{{ app.name }}/src",
    ...
  }
}

Then that name can be used in workspaces.json to apply the template.

E.g.

{
  "version": 2,
  "projects": {
    "my-app": {
      "nx-template": "my-template"
    }
  }
}

Thanks for reading.
