      All of these tweets seem fairly vague alone, but in aggregate they tell a larger story. This will be open source. I don't know when. I am the only one working on it (hopefully not for long). Happy to answer any questions.

          Are you planning to include any tool for API documentation? I've always thought it'd be cool if documentation were built into my package manager, e.g. `rome docs react` might let me browse the docs for a package right there in the terminal.

          npm already has a solution for that, man pages. It's a specific field in package.json. It could be a lot easier to automatically build and consume them though. Using existing standards is preferred, I wouldn't want to bifurcate the ecosystem unless it was substantially worth it.

          Does it have its own type system? Would be awesome for type aware linting or compiler optimizations

          It does. Not clear how far to actually go with it though. It's architecture is a combination of Flow + TypeScript with some additional concepts that allow it to represent non-type information for use in an optimizing compiler. Regardless, would want to interop with Flow + TS.
