Project structure:

   test.ts
   tsconfig.json

// foo/test.ts

interface Foo {
    x: number;
}

export default Foo;

// foo/tsconfig.json 
{
    "compilerOptions": {
        "composite": true,
        "outDir": "../out/foo"
    },
    "include": [
        "*.ts"
    ]
}

// bar/test.ts

import Foo from '../foo/test';

// bar/tsconfig.json 
{
    "compilerOptions": {
        "composite": true,
        "outDir": "../out/bar"
    },
    "include": [
        "*.ts"
    ],
    "references": [
        {"path": "../foo"}
    ]
}
