var testFolder = '/zip_file\ /sit1_Wave2_Settlement_afx_formula\ \

var fs = require('fs');
fs.readdir(testFolder, (err, files) => {
files.forEach(file => {
console.log(file);
});
})
I need to read a file contents, if i execute the above code it shows an error.
files.forEach(function(file) {
^
TypeError: Cannot read property 'forEach' of undefined
You should check for errors before trying to read the files, and then check to see if the files object is defined, like this:
fs.readdir(testFolder, (err, files) => {
if (err) throw err;
if (files){
files.forEach(file => {
console.log(file);
});
} else {
console.log('no files found')
}
});
