{ "compilerOptions": { "rootDir": "src" "target": "es3", } }
Használat:
tsc
A fordító programot, paraméterek nélkül hívjuk.
Van egy paraméter, amit beállítófájl mellett is megadhatunk: --watch, vagy röviden -w.
A célokról itt olvashat többet:
A beállítások felsorolása:
{ "compilerOptions": { "target": "es3", "watch": true, "lib": ["dom", "es2017"] } }
{ "rootDir": ["src"] }
A rootDir helyett használható a rootDirs, amelynek tömböt kell megadnunk, így több könyvtár is megadható.
A forrás az src a cél a public könyvtár:
{ "compilerOptions": { "rootDir": "src", "outDir": "public" } }
Egy komplexebb megoldás:
{ "compilerOptions": { "rootDir": "src", "target": "es5", "strict": true, "watch": true } }
A tsc parancs képes generálni --init tsconfig fájl, amelyben lesz néhány alapbeállítás, és még több megjegyzésbe.
tsc --init

Az include nem fordítókapcsoló. Ezért nem írjuk a compilerOptions-ba. Használata hasonló a rootDir kapcsolóhoz.
