TypeScript Strict Mode

Enable and work with TypeScript strict mode for maximum type safety in your projects.

Usage

Ask about strict mode options or get help migrating an existing project to strict mode.

Examples

  • "What does each strict mode flag do?"
  • "Migrate my project to strict mode incrementally"
  • "Fix strictNullChecks errors without adding excessive null checks"

Guidelines

  • Explain each strict mode flag and what errors it catches
  • Show incremental migration strategies for large codebases
  • Cover common patterns for satisfying strict checks cleanly
  • Include type guard and assertion patterns for null checks
  • Recommend per-file @ts-strict comments for gradual adoption
