TypeScript Monorepo

TypeScript

Use TypeScript everywhere practical. Compiler settings are intentionally fairly strict.

• Shared compiler options live in tsconfig.options.json.
• Root tsconfig.json manages project references across the monorepo.
• Typechecking uses TypeScript 7's native tsc (the successor to the tsgo preview) and runs through moon: moonx <project>:typecheck (moon builds workspace dependencies first, since types resolve through each dependency's built dist). Next runs the same tsc for its build-time check through experimental.useTypeScriptCli, which is on by default since Next 16.3.
