Doesn't seem to work with monorepos

I am trying to convert https://github.com/vega/vega/tree/master/packages/vega-util, which is a package in a monorepo and already has typings. Running npx ts-migrate-full packages/vega-util from the root results in the following logs and no changes to the files. Am I using the tool incorrectly or is it not intended for my use case?

Welcome to TS Migrate! :D

This script will migrate a frontend folder to a compiling (or almost compiling) TS project.

It is recommended that you take the following steps before continuing...

1. Make sure you have a clean git slate.
   Run `git status` to make sure you have no local changes that may get lost.
   Check in or stash your changes, then re-run this script.

2. Check out a new branch for the migration.
   For example, `git checkout -b dominik--ts-migrate` if you're migrating several folders or
   `git checkout -b dominik--ts-migrate-vega-util` if you're just migrating packages/vega-util.

3. Make sure you're on the latest, clean master.
   `git fetch origin master && git reset --hard origin/master`

4. Make sure you have the latest npm modules installed.
   `npm install` or `yarn install`

If you need help or have feedback, please file an issue on Github!

Set a custom path for the typescript compiler. (It's an optional step. Skip if you don't need it. Default path is ./node_modules/.bin/tsc.):
Your default tsc path is ./node_modules/.bin/tsc.

[Step 4 of 4] Checking for TS compilation errors (there shouldn't be any).

./node_modules/.bin/tsc -p packages/vega-util/tsconfig.json

All done!

The recommended next steps are...

1. Sanity check your changes locally by inspecting the commits and loading the affected pages.

2. Push your changes with `git push`.

3. Open a PR!

@domoritz your tsconfig.json file doesn’t include src and test files. That’s why the ts-migrate cannot change any files (we’re getting a list of the files to convert from tsconfig). Try to include src and test files to the tsconfig.json file of the vega-util package:

"include": [
  "src", "test"
],

and run ts-migrate once again from the root.

@domoritz I’m not aware of any of these tools 😦 https://github.com/typescript-cheatsheets/react/blob/master/docs/migration/from-js.md#automated-js-to-ts-conversion here is a good list of the existing tools, but as far as I know, none of them doing this.
