CouchDB adapter for Lockit.

npm install lockit-couchdb-adapter

var adapter = require('lockit-couchdb-adapter');

The adapter automatically saves the necessary views to your CouchDB. You only need the connection string in your config.js.

exports.db = 'http://127.0.0.1:5984/';

adapter.save(name, email, pass, callback)

• name: String - i.e. 'john'
• email: String - i.e. '[email protected]'
• pass: String - i.e. 'password123'
• callback: Function - callback(err, user) where user is the new user now in our database.

The user object has the following properties

• _id: unique id from CouchDB
• _rev: revision from CouchDB
• password_scheme: pbkdf2
• iterations: pbkdf2 iterations
• name: name chosen during sign up
• email: email that was provided at the beginning
• roles: Array with roles a user has, default is ['user']
• type: document type for views, default is 'user'
• signupToken: unique token sent to user's email for email verification
• signupTimestamp: Date object to remember when the user signed up
• signupTokenExpires: Date object usually 24h ahead of signupTimestamp
• failedLoginAttempts: save failed login attempts during login process, default is 0
• derived_key: password hash generated by pbkdf2
• salt: salt generated by crypto.randomBytes()

  if (err) console.log(err);
  console.log(user);

  // add some new properties to our existing user
  user.newKey = 'and some value';
  user.hasBeenUpdated = true;

  // save updated user to db

    if (err) console.log(err);
    // ...
  });
});
