TSConfig

This setting lets you specify a file for storing incremental compilation information as a part of composite projects which enables faster building of larger TypeScript codebases. You can read more about composite projects in the handbook.

The default depends on a combination of other settings:

• If outFile is set, the default is <outFile>.tsbuildinfo.
• If rootDir and outDir are set, then the file is <outDir>/<relative path to config from rootDir>/<config name>.tsbuildinfo For example, if rootDir is src, outDir is dest, and the config is ./tsconfig.json, then the default is ./tsconfig.tsbuildinfo as the relative path from src/ to ./tsconfig.json is ../.
• If outDir is set, then the default is <outDir>/<config name>.tsbuildInfo
• Otherwise, the default is <config name>.tsbuildInfo
