tsconfig.json

// https://www.typescriptlang.org/tsconfig#extends
// The configuration from this file is loaded first, then overridden by those in the inheriting config file. But path-based compiler options (outDir, outFile, rootDir, include, exclude, files) are resolved from the config file they're found in. They cannot be extended (https://github.com/microsoft/TypeScript/issues/29172).
