I am trying to make a random string picker with a text document that splits at every line.
However, when I try to run it, it says that data.split is not a function.
fs.readFile('list.txt', function(err, data){
if(err) throw err;
var lines = data.split('\n');
var rand = [Math.floor(Math.random()*lines.length)];
var rlist = lines[rand]
})
As stated in the documentation:
The callback is passed two arguments (err, data), where
datais the contents of the file. If no encoding is specified, then the raw buffer is returned.
A raw buffer is just an array, and JavaScript arrays don't have the split function. So you need to specify an encoding to get the text result.
fs.readFile('list.txt', 'utf8', ...)
