✅ Viability Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

⭐ Suggestion

Allow tsc --build --noEmit, the relevant types can be emitted to the tsbuildinfo for incremental building. This is very useful to allow type checking only for projects using project references and working with a bundler. e.g. A create-vue project, which currently has to resort to hackery such as vue-tsc --noEmit -p tsconfig.vitest.json --composite false which is not as accurate as type checking each project individually.

📃 Motivating Example

tsc --build --noEmit is now supported, allowing to only run type checking for projects using project references that don't also build types using tsc.

💻 Use Cases

Type checking only, for projects using other build tools than tsc but still using project references for each of configuration.

Commencez par étudier la gestion existante de tsc --build pour les références de projets et la génération incrémentielle de tsbuildinfo ; l’issue ne nomme aucun fichier ni test spécifique. Le travail est considéré comme terminé lorsque tsc --build --noEmit effectue la vérification des types sans émettre de types, tout en enregistrant les informations pertinentes pour les builds incrémentiels.
