hapi-auth-couchdb-cookie Build Status

hapi CouchDB Cookie authentication plugin, heavily inspired by hapi-auth-cookie.

CouchDB Cookie authentication provides authentication via a CouchDB. It checks the user credentials with a CouchDB and passes the Cookie from CouchDB to the user. All following requests can use the cookie for access. A validateFunc can be passed in, in case the cookie's content requires validation on each request. Note that cookie operates as a bearer token and anyone in possession of the cookie content can use it to impersonate its true owner.

Installation

npm install hapi-auth-couchdb-cookie --save

Usage

The Plugin works out of the box by just including it, if CouchDB runs on the default port. However, you can customize the behaviour with the properties noted below.

server.register(require('hapi-auth-couchdb-cookie'), function (err) {
  server.auth.strategy('session', 'couchdb-cookie', {});
});

Because this scheme decorates the request object with session-specific methods, it cannot be registered more than once.

Options

redirectTo

Type String | Default false

Optional login URI to redirect unauthenticated requests to. Note that using redirectTo with authentication mode 'try' will cause the protected endpoint to always redirect, voiding 'try' mode. To set an individual route to use or disable redirections, use the route plugins config ({ config: { plugins: { 'hapi-auth-couchdb-cookie': { redirectTo: false } } } }).

appendNext

Type String|Boolean | Default false

If true and redirectTo is true, appends the current request path to the query component of the redirectTo URI using the parameter name 'next'. Set to a string to use a different parameter name. Defaults to false.

getNextValue

Type function | Default undefined

If redirectTo and appendNext are true and it is a function, getNextValue gets called with the request object as the only parameter. It should return a String that is used as the value of either 'next' or the String set as appendNext in the url for the redirect.

redirectOnTry

Type Boolean | Default true

If false and route authentication mode is 'try', authentication errors will not trigger a redirection. Requires hapi version 6.2.0 or newer.

couchdbUrl

Type String | Default http://localhost:5984

URL of the CouchDB to authenticate to.

validateFunc

Type Function | Default function() {}

An optional session validation function used to validate the content of the session cookie on each request. Used to verify that the internal session state is still valid (e.g. user account still exists). The function has the signature function(session, callback) where:

  • session - is the session object set via request.auth.session.set().
  • callback - a callback function with the signature function(error, isValid, credentials) where:
    • error - an internal error.
    • isValid - true if the content of the session is valid, otherwise false.
    • credentials - a credentials object passed back to the application in request.auth.credentials. If value is null or undefined, defaults to session. If set, will override the current cookie as if request.auth.session.set() was called.

request.auth.session.authenticate(username, password, callback)

Call this to authenticate against CouchDB. Takes three params.

username

Type String | No default

The username to authenticate

password

Type String | No default

The password of the user to authenticate

callback

Type function | No default

Called when the authentication took place with to params:

  • error An optional error object containing the reason (most likely unauthenticated)
  • credentials The credentials from CouchDB

request.auth.session.clear()

Call this to clear authentication against CouchDB.
