Frequently Asked Questions
What are the essential tsconfig.json options?
The core settings are target (JS output version, e.g., ES2020/ESNext) and module (module system, e.g., ESNext/CommonJS). Strongly recommend enabling strict mode for full type safety. Also set outDir and rootDir.
What does strict mode include?
strict: true enables: strictNullChecks, noImplicitAny, strictFunctionTypes, strictBindCallApply, noImplicitThis, and alwaysStrict. These catch common bugs and improve code quality significantly.
How to choose target and module?
Target determines JS syntax level: ES5 for old browsers, ES2020/ESNext for modern features. Module determines module system: CommonJS for Node.js, ESNext for frontend, ESNext+esModuleInterop for libraries.
