TypeScript Skill (2025-2026 Edition)
This skill outlines the latest best practices for writing robust, performant, and type-safe TypeScript code, aligned with the 2025-2026 ecosystem (TypeScript 5.x and beyond).
🚀 Key Trends & Features (2025/2026)
- Native Speed: The transition to a Go-based compiler (native port) is underway (TS 7+), promising massive performance gains.
- Default Strictness: Modern projects treat
strict: trueas the absolute baseline. - Framework First: TS is now deeply integrated into frameworks (Next.js, Remix, NestJS) rather than an add-on.
🛠️ Configuration Best Practices (tsconfig.json)
Use strict defaults to prevent bugs before they happen.
