@modular-scripts/workspace-resolver

This package encapsulates two functions:

1. resolveWorkspace - Searches the filesystem (at a given modular root) for workspace packages, returning a flat map of all packages found, with an additional type field containing the modular type (if present). An optional 2nd argument of target can be passed, which sets the working directory that workspaces should be resolved from. This can be useful when the modular root needs to be different to the current working directory, such as when modular convert or port happens.
2. analyzeWorkspaceDependencies - Analyzes package.json files for a set of workspace packages, returning a flat object for each package, listing out workspace inter-dependencies plus and mismatched dependencies. The dependencies are analyzed according to dependencies defined in package.json files. The resulting output intends to match the yarn v1 (classic) output for yarn workspaces info (1)

In most cases, the output of resolveWorkspace can be passed directly to analyzeWorkspaceDependencies.

(1) This package exists as a drop-in replacement for yarn workspaces info because the yarn command is not consistent across other versions of yarn.

Example

const [workspacePackages] = resolveWorkspace('path/to/modular/project/root')

/*
Map {
    "example-package": {
        path: 'packages/example-package',
        name: 'example-package',
        workspace: false,
        version: '1.0.0',
        modular: {
            type: 'package'
        },
        type: 'package',
        children: [],
        parent: null,
        dependencies: {
            'lodash': '10.0.0'
        }
    },
    ...
}
*/

const analyzed = analyzeWorkspaceDependencies(workspacePackages);

/*
{
  "example-package": {
    "location": "packages/example-package",
    "workspaceDependencies": ['another-package'],
    "mismatchedWorkspaceDependencies": []
  },
  "another-package": {
    "location": "packages/another-package",
    "workspaceDependencies": [],
    "mismatchedWorkspaceDependencies": ['mismatched-dep-one']
  },
