TypeScriptstyle

TypeScriptstyle is a hypothetical coding standard for TypeScript projects that emphasizes readability, maintainability, and type safety. It describes recommended conventions for naming, typing, module organization, and project configuration to produce consistent and robust TypeScript code across teams.

Although not an official standard, TypeScriptstyle emerged in community discussions and sample repositories during the 2020s as an attempt to harmonize TypeScript usage beyond individual projects. It draws on patterns from popular style guides and adapts them to the typed nature of TypeScript.

Core principles include strict typing for public APIs, explicit return types, avoidance of any, and the use of strict null checks. The guide also favors clear module boundaries, descriptive naming, and consistent formatting. It encourages leveraging advanced TypeScript features such as discriminated unions and mapped types where appropriate.

Conventions cover file and folder organization, export patterns for public modules, and guidelines for documenting types and interfaces. Public APIs should be well documented with JSDoc-style comments, while internal code may rely more on inferred types when their intent is clear.

Tooling and adoption typically involve ESLint with TypeScript plugins, Prettier for formatting, and a strict tsconfig.json configuration. Proponents argue the style improves collaboration and maintenance, while critics note the potential for rigidity and slower onboarding in new projects.
