Does this skill help with existing projects?

Yes, it includes a guide for incrementally upgrading existing projects by adding strict flags and fixing errors step-by-step.

What is the core principle of this TypeScript skill?

The core principle is zero tolerance for 'any' types, requiring every value to have an explicit, meaningful type to prevent runtime errors.

How does it handle array indexing safety?

It enables the 'noUncheckedIndexedAccess' flag, which forces the compiler to treat array access as potentially undefined, requiring explicit checks.

What version of ECMAScript does it target?

The provided template defaults to ES2022, providing a modern environment for both language features and library support.

Developer Tools

Enforces maximum type safety and zero-tolerance for 'any' types through a pre-configured, strict TypeScript environment.

About

The TypeScript Strict Configuration skill provides a battle-tested blueprint for developers who prioritize code quality and runtime reliability. It automates the setup of a 'zero-tolerance for any' policy by pre-configuring all essential strictness flags, including strictNullChecks, noImplicitAny, and noUncheckedIndexedAccess. Beyond providing a production-ready tsconfig.json template, the skill offers robust implementation patterns for type guards, catch variables, and safe array access, ensuring your TypeScript codebase remains resilient, self-documenting, and free from common runtime errors.
