A fairly substantial PR was accepted recently to integrate the typescript server as the language client for atom-ide: https://github.com/atom/ide-typescript

It appears the project isn't dead, but there aren't any Facebook maintainers working on it (and there haven't been for nearly a year).

Ok sorry, the atom-ide-ui package is dead. I’m not sure how the IDE features are split between the ui and individual language server packages
