Creating Plugins

There are many ways to extend verdaccio, currently we only support authentication plugins

Authentication Plugins

This section will describe how it looks like a Verdaccio plugin in a ES5 way. Basically we have to return an object with a single method called authenticate that will recieve 3 arguments (user, password, callback). Once the authentication has been executed there is 2 options to give a response to verdaccio.

OnError

Either something bad happened or auth was unsuccessful.

callback(null, false)

OnSuccess

The auth was successful.

groups is an array of strings where the user is part of.

 callback(null, groups);

Example

function Auth(config, stuff) {
  var self = Object.create(Auth.prototype);
  self._users = {};

  // config for this module
  self._config = config;

  // verdaccio logger
  self._logger = stuff.logger;

  // pass verdaccio logger to ldapauth
  self._config.client_options.log = stuff.logger;

  return self;
}

Auth.prototype.authenticate = function (user, password, callback) {
  var LdapClient = new LdapAuth(self._config.client_options);
  ....
  LdapClient.authenticate(user, password, function (err, ldapUser) {
    ...
    var groups;
     ...
    callback(null, groups);
  });
};

module.exports = Auth;
