The best IDE for TypeScript

/**
 * We convert a `tsconfigFilePath` to a project in a background process
 * However because we might have files edited in main server memory the background process would need to query the master for *current* file contents
 * This can be slow (and can cause nasty deadlocks).
 * So we use this this `projectDataLoader` to load all the data upfront in the server memory and push it down to the worker
