TypeScript Style Guide Review

When reviewing TypeScript code, check against these sections. For full rules and examples, see google-ts-styleguide.md.

1. Source File Structure

• File order: copyright, @fileoverview, imports, implementation
• Use named exports only — no default exports
• Use ES6 modules — no namespace, no require()
• Prefer namespace imports for large APIs, named imports for frequently used symbols
• No mutable exports (export let) — use getter functions instead
• See google-ts-styleguide.md § 3. Source file structure

2. Variables & Literals

• const by default, let when reassigned, never var
• One variable per declaration
• Single quotes for strings, template literals for concatenation
• No Array() or Object() constructors
• See google-ts-styleguide.md § 4. Language features
