Option to lint entire workspace and/or to prevent running apps with tslint errors

I just switched from create-react-app-typescript (which is now deprecated) to CRA 2.1.1 with TypeScript support. There are two gaps I'm trying to address.

I followed the VSCode setup instructions for create-react-app-typescript and it's working great to find lint errors in files that I'm currently editing. But I can't figure out how to lint my entire project, including files that aren't currently open in VSCode, whenever I load my workspace or change a file that might impact other files. Is there a way to do this by default?

The second thing I'm missing from other non-CRA projects is the ability to block npm start if there are lint errors. This comment from @WorldMaker pointed to typescript-tslint-plugin as the missing tslint support in CRA 2.x. Can typescript-tslint-plugin force CRA 2.x's npm start to report lint errors, just like it will for "compiler" errors that are caught by Babel?

This sounds like a good use case for a task: https://code.visualstudio.com/Docs/editor/tasks

The tslint-plugin-extension includes a task problem matcher you can use for a tslint task: https://github.com/Microsoft/vscode-typescript-tslint-plugin
