typescript-satisfies-operator

What problem does it solve?

This Skill helps TypeScript developers keep literal types when validating values, avoiding unwanted type widening that occurs with standard type annotations.

Core Features & Use Cases

• Preserve literal types in object literals by using the satisfies operator for type validation without changing the inferred type.
• Compare with colon annotations and as const to understand when to prefer each approach in real-world codebases.
• Use case: when constructing a config object that should remain a narrow union type for precise autocomplete and safety.

Quick Start

Create a TypeScript snippet that demonstrates validating an object with satisfies to preserve a literal type and contrasts it with a colon-annotated version.
