Description
Hello everyone!
I'm not quite sure that this is really a bug or if I am missing a simple configuration option but I googled for 1.5 hours and came up with nothing:
TypeScript Version: 3.0.0-dev.20180619
Search Terms: Stale error, watch mode, saved file, closed file
Code
File a.ts:
import test from './b';
test(4, 5);File b.ts:
function test(x: number, y: number) {
return x + y / 5;
}
export
6657
default test;tsconfig.json:
{
"compilerOptions": {
"module": "commonjs",
"noEmit": true,
"strict": true,
"watch": true
}
}Expected behavior:
When running tsc on console, everything is fine. When one of the parameter types in b.ts is changed to string, the running compiler (in watch mode) should now show an error, becuase test is called with 2 numbers.
Actual behavior:
Errors only show up when compiler is restarted or when a.ts is saved.
