Writing to files in Node.js

I've been trying to find a way to write to a file when using Node.js, but with no success. How can I do that?

There are a lot of details in the File System API. The most common way is:

const fs = require('fs');

fs.writeFile("/tmp/test", "Hey there!", function(err) {
if(err) {
return console.log(err);
}
console.log("The file was saved!");
});

// Or
fs.writeFileSync('/tmp/test-sync', 'Hey there!');
