Edit: as indicated by commenter, this solution has a problem. printResolver could be made into an array, but using top solution is much easier

A synchronous print function that also works with pipes aka FIFO's, using Async/await. Make sure you always call "print" with "await print"

let printResolver;
process.stdout.on('drain', function () {
    if (printResolver) printResolver();
});

async function print(str) {
    var done = process.stdout.write(str);
    if (!done) {
        await new Promise(function (resolve) {
            printResolver = resolve;
        });
    }
}
