Quick answers
Q: Does luau2ts need Rojo installed?
A: No. luau2ts reads default.project.json directly; the Rojo binary is only needed if you also want to sync the Luau source into Roblox Studio.
Q: Can I run luau2ts and roblox-ts on the same project?
A: Yes. They go in opposite directions: roblox-ts compiles TS → Luau, luau2ts compiles Luau → TS. They can coexist in a build pipeline, although in practice you usually pick one direction as the source of truth and treat the other as generated.
Q: What Luau features are supported?
A: All upstream Luau conformance tests pass (53/53). Generics, type aliases, exact tables, type assertions, string-interpolation backtick literals, generalized iteration, --!strict, --!nonstrict are all supported.
Q: Does it emit JSX for Roact components?
A: No. The shape of Roact.createElement(component, props, children) is preserved verbatim. JSX is a roblox-ts-side feature.
