});how to export fs.readFile
var fs = require('fs');
module.exports = {
parseFile: function(file_path, callback) {
fs.readFile(file_path.toString(), 'utf-8', function(err, data) {
if (err) return callback(err);
callback(null, data);
});
}
}
// much shorter version
exports.parseFile = function(file_path, callback) {
fs.readFile(file_path.toString(), 'utf-8', callback);
