@bheftel Hi Brannon, please review this PR when you have time. Also let me know if you need more context!

Hey @zaowang-ms - this looks reasonable to me, but you're right that I don't have a lot of context. @ornj probably has more context, and that is probably more important than familiarity with typescript syntax.

Hi Brannon, thanks for reviewing it although I guess it can be a bit too much to review as we are introducing a brand-new project in this repo. As we discussed above, it would be muchly appreciated if @ornj has any contextual comments or thoughts on this PR.

General comments:

• Please review your code and documentation for things like spelling errors
• I see a bunch of variation in indentation, line breaks, etc. Suggest adding a formatter to keep things consistent. It might seem like a silly thing but it makes code easy to read and easier to contribute to.
• Consider adding a linter. I don't know what the cool kids use these days but way back when I was partial to eslint.

Hi @ornj , thanks for the careful reviews. I have made correspond changes and I think feedbacks from your side helped increase the codebase a lot. Could you take a look and see if there are any other changes needed?

Also, I think I may need a separate PR to create a shared Readme.md and also make some modifications on the release json. Once all that are done, we're good to release it.
