Project Documentation

Filegen.js

shouldCopy()

FileGen.prototype.shouldCopy = function(cb) {
     if(fs.existsSync(this.moduleName)){
         console.log(this.moduleName+' is already exists.');
         readline.question('Do you want to overwrite it ?? (Y / N):', function(answer){
             readline.close();
             answer = answer.toLowerCase();
             var yes = ['y','yes'];
             if(yes.indexOf(answer)!== -1){
                 return cb(true);
             } else {
                 return cb(false);
             }
         });
     } else{
         readline.close();
         return cb(true);
     }
};

This function search for the existence of given Module name. then :

• If module is not exists then it returns true as callback
• If module exists then it informs to the user and ask for overwrite
  • if user replies with yes then it returns true as callback
  • if user replies with no (any thing else, except - 'y', 'yes', 'Y', 'YES') then it returns false as callback

fs.existsSync()

fs.existsSync() does not use a callback.

Readline

readline.question(question, function(answer){
    console.log(`Thank you for your valuable feedback: ${answer}`);
    rl.close(); 
})

It prints a question to console to reply from user.
