To scaffold a TypeScript library with namespace-module conventions, use a tool that automates creating the src/lib/<name>/ structure, including implementation files, barrel exports, and test files, while outlining package.json and tsconfig updates.

TypeScript library file naming conventions should use _.ts for the namespace module, __.ts for the barrel export, _.test.ts for tests, and _.test.fixture.ts for shared test fixtures to maintain a consistent project structure.

Configuring package.json imports and tsconfig paths for a new TypeScript package requires wiring exports to match the namespace-module structure, ensuring the build configuration correctly resolves the barrel files and implementation modules.

Yes, you can scaffold both simple TypeScript libraries with one implementation file and complex libraries with multiple implementation files, automatically generating a barrel export file when needed to manage the module structure.

The best way to reduce boilerplate when creating a TypeScript package is to use a scaffolding tool that enforces a consistent project structure, automating file naming, export barrels, and build configuration according to documented conventions.

Barrel exports, designated by __.ts files, are needed in TypeScript libraries to aggregate multiple module exports into a single entry point, simplifying imports and ensuring the namespace-module conventions are properly maintained.
