TypeScript Development Standards

Type Safety

  • Strict Type Checking: Always enable and adhere to strict type checking. This helps catch errors early and improves code quality.
  • Prefer Type Inference: Allow TypeScript to infer types when they are obvious from the context. This reduces verbosity while maintaining type safety.
  • Avoid any: Do not use the any type unless absolutely necessary as it bypasses type checking. Prefer unknown when a type is uncertain and you need to handle it safely.
  • Use strict null checks (no null or undefined without explicit handling)
  • Use type guards and union types for robust type checking

Naming Conventions

  • Use PascalCase for types, interfaces, and classes
  • Use camelCase for variables, functions, and methods
  • Use UPPER_CASE for constants

Modern TypeScript Patterns

  • Use optional chaining (?.) and nullish coalescing (??)
  • Prefer const over let; never use var
  • Use arrow functions for callbacks and short functions
  • Avoid enums - they generate additional code at compile time, which increases the size of the final file. This can have a negative impact on the loading speed and performance of the app. Prefer union types or literal types instead.
