# Issues with tsc

tsc, the native TypeScript CLI, pretty much offers everything that we need to compile and bundle our TypeScript libraries. We opted for tsup due to tsc lacks of support for CSS imports, a requirement for enabling Chromatic's TurboSnap feature.

Given that either TurboSnap requirements or tsc CSS imports support change, we will reevaluate this decision.
