Many of the libraries we use (including React) already have type definitions available.
Sentry’s first Typescript Pull Request: https://github.com/getsentry/sentry/pull/13786
One downside to relying on the type definitions in DefinitelyTyped is that occasionally the library types are not written by the maintainers. Instead, community users contribute types, and because of that some types are missing or incorrectly defined. We encountered this with the versions of ECharts and Reflux we were using. Our solution here was to add additional type definitions in our code.
In addition, our fantastic tools team introduced a slackbot that would allow us to track progress on demand. Seeing the number go up every day was a big motivator in the final stages, so much so it’s something we’ll likely to use again. You can find the early versions of that bot here.
