Questions
What is tsconfig.json?
tsconfig.json is the configuration file for the TypeScript compiler. It specifies compiler options like target JavaScript version, module system, strict type checking, and which files to include or exclude from compilation.
What does the strict option do?
The strict flag enables a set of strict type-checking options including strictNullChecks, strictFunctionTypes, strictBindCallApply, strictPropertyInitialization, noImplicitAny, noImplicitThis, and alwaysStrict.
What target should I set in tsconfig.json?
Set target to match your minimum runtime environment. Use "es2022" or "esnext" for modern Node.js, "es2020" for broad browser support, and "es2015" if you need to support older environments. The target determines which JavaScript features are downleveled.
What is the difference between module and moduleResolution?
The "module" option sets the output module format (commonjs, esnext, nodenext). The "moduleResolution" option controls how TypeScript finds imported files. Use "nodenext" for both when targeting modern Node.js projects.
Can I extend a shared tsconfig from this generator?
Yes. The generated file can serve as a base config. Other tsconfig files can extend it using the "extends" field, e.g., "extends": "./tsconfig.base.json", and override specific options.
