Nodejs check file exists, if not, wait till it exist

Question

I\'m generating files automatically, and I have another script which will check if a given file is already generated, so how could I implement such a function:

f

Here is the solution:

// Wait for file to exist, checks every 2 seconds
function getFile(path, timeout) {
    const timeout = setInterval(function() {

        const file = path;
        const fileExists = fs.existsSync(file);

        console.log('Checking for: ', file);
        console.log('Exists: ', fileExists);

        if (fileExists) {
            clearInterval(timeout);
        }
    }, timeout);
};
