At Slack, we use one JavaScript codebase to build a multi-threaded desktop application, routinely interacting with native code. Managing large JavaScript codebases is challenging - we need a guarantee that the individual pieces fit together. In the desktop world, a small mistake is likely to result in a crash. To that end, we adopted TypeScript and quickly learned to stop worrying and love the compiler. See an introduction and a detailed account of porting a large code base, learn why exactly TypeScript is so popular, what the downsides are, and how you would slowly adopt it in your development.
