There are two examples of tsconfig.json presented on the official website of TypeScript,—one with "files" property, another one with "include" and "exclude" properties specified:
Using the
"files"property{ "compilerOptions": { // irrelevant }, "files": [ "core.ts", "sys.ts", "types.ts", "scanner.ts", "parser.ts", "utilities.ts", "binder.ts", "checker.ts", "emitter.ts", "program.ts", "commandLineParser.ts", "tsc.ts", "diagnosticInformationMap.generated.ts" ] }Using the
"include"and"exclude"properties{ "compilerOptions": { // irrelevant }, "include": [ "src/**/*" ], "exclude": [ "node_modules", "**/*.spec.ts" ] }
So, basically, "files" is used to specify separate files directly by their path, while "include" and "exclude" is used to target collections or groups of files or folders etc.
