TypeScript · Junior · Question 70 of 75

How do you check types in CI when a bundler (Vite, esbuild) already compiles TS without type checking?

✓Correct answer: Run tsc --noEmit as a separate step
2Bundlers always type-check
3Type checking isn't possible with bundlers

Explanation

Fast bundlers only strip types. A separate tsc run (or vue-tsc for Vue) catches type errors without producing files.
