TypeScript References Yarn Workspaces Sync Utility

This library ensures that project references in TypeScript tsconfig.js files are automatically kept up to date in a project using Yarn 2 workspaces.

Running this script will:

• Add a list of all packages in the workspaces to the root tsconfig.json for the "references" attribute:

{
  "references": [
    {
      "path": "workspaces/apps"
    },
    {
      "path": "workspaces/docs"
    },
    {
      "path": "workspaces/templates"
    },
    {
      "path": "workspaces/templates-lib"
    }
  ]
}

• Update all the "references" in the tsconfig.json for all packages in the workspace so that it includes all the packages that it declares as a dependency in package.json.

Usage

Install as development dependency using

npm i @goldstack/utils-typescript-references --save-dev
-- or
yarn add -D @goldstack/utils-typescript-references

Add a script to your package.json

{
  "scripts": {
    "fix-typescript-references": "utils-typescript-references"
  }
}

Run the script using

npm run fix-typescript-references
-- or
yarn fix-typescript-references

Options

The following parameters can be passed when invoking the script:

--help

Shows a reference of all available options:

$ utils-typescript-references --help
Options:
  --help                 Show help                                     [boolean]
  --version              Show version number                           [boolean]
  --skipPackages         Only update project references in the root tsConfig
                                                                       [boolean]
  --skipRoot             Skip updating project references in project root
                         tsConfig                                      [boolean]
  --excludeInReferences  Exclude specific packages from being referenced by
                         other packages                                  [array]
  --excludeInRoot        Exclude specific packages from being referenced in the
                         root tsConfig                                   [array]
  --tsConfigName         Names of tsConfig files to be updated           [array]

--tsConfigName

Provide one or more name of tsconfig.json files in projects across the monorepo that should be updated.

$ utils-typescript-references --tsConfigName tsconfig.json --tsConfigName tsconfig.build.json

Defaults to tsconfig.json

This helpful for monorepos where for instance the tsconfig.build.json builds the modules that are exported from the package, and thus should be run when you are building using tsc -b. In this case the tsconfig.json can be set up to type check only (no emit) and have a manually inserted reference to tsconfig.build.json for running tsc -b.

Note that once any --tsConfigName is provided, the default tsconfig.json is not updated any more. In order to continue updating tsconfig.json along with any custom configuration files, simply provide it as an extra option:

$ utils-typescript-references --tsConfigName tsconfig.build.json --tsConfigName tsconfig.json

This option can also be used if the tsconfig.json file is not in the root of packages (e.g. in the src/ folder). In that case, provide an option as follows:

$ utils-typescript-references --tsConfigName src/tsconfig.json --tsConfigName tsconfig.json

--excludeInReferences

Will prevent certain packages from being added to the references of other projects in the monorepo.

$ utils-typescript-references --excludeInReferences @myproject/packageA --excludeInReferences @myproject/PackageB

The above will cause @myproject/packageA and @myproject/packageB not to be inserted as referenced in all other packages of the monorepo.

--excludeInRoot

Will prevent certain packages from being added to the references section of the root tsconfig.json file.

$ utils-typescript-references --excludeInRoot @myproject/packageA --excludeInRoot @myproject/PackageB

--skipPackages

Will skip updating the references in tsconfig.json files for all packages in the project.

$ utils-typescript-references --skipPackages

--skipRoot

Will skip updating the references in the tsconfig.json file for the project root.

$ utils-typescript-references --skipRoot

Limitations

• The root tsconfig.json file needs to be a vanilla JSON document (so no comments)

If these limitations or anything else are an issues, please raise a ticket in GitHub for the Goldstack Monorepo.
