Creating a JSON file(MongoDb Collection) of User Info for a Node.js application that uses Bcrypt and passport for login - node.js

Question

I'll try and word this question as short and clear as possible. I have a node.js project that connects to a non local instance of MongoDB using mongoose. I have written code for a user to login using passport module. I create a JSON file as a users collection. When I go to sign in I get this error
throw "Not a valid BCrypt hash."
So If I wanted to just create a JSON file of Users to work with this how would I go about it? My end goal is to convert RDBMS to MongoDB. Just starting with the users table. I understand that if I was registering new users I could just make a function that would hash their password like
newUser.password= createHash(password)
var createHash = function(password){
return bCrypt.hashSync(password, bCrypt.genSaltSync(10), null);
}
or something along those lines. Summary: How do I make a JSON file of user info for MongoDB that'll work with bcrypt hash and passport?

Answer 1

var fs = require('fs');
var bc = require('bcrypt-nodejs')
fs.readFile('users.txt',function(err,data){
var x = [];
if(err) throw err;
var buf = new Buffer(data);
x = buf.toString();
x = JSON.parse(x);
//console.log(x);
for(var a in x){
x[a].password=createHash(x[a].password);
}
x = JSON.stringify(x);
fs.writeFile('users.txt',x,callback()); //or just push directly to db?
});
var createHash = function(password){
return bc.hashSync(password, bc.genSaltSync(10), null);
}
function callback(){
console.log('finished');
}
Just read in my User Info , Bcrypted the passwords and made a new file. Put it in Mongo. Hopefully this helps someone else. If anyone has a better solution for me I'd appreciate it.
