connect-arango

ArangoDB session store for Connect.

## Notes

Requires that database is created.

Installation

via npm:

$ npm install github:carlitux/connect-arango

Options

hash (optional) Hash is an object, which will determine wether hash the sid in arango, since it's not undefined, means sid will be hashed
hash.salt Salt will be used to hash the sid in arango, default salt is "connect-arango"
hash.algorithm Hash algorithm, default algorithm is "sha1"
db An object with url and databaName fields url default to: http://localhost:8529 you can use http://user:pass@localhost:8529
collection Collection (optional, default: sessions)
stringify If true, connect-arango will serialize sessions using JSON.stringify before setting them, and deserialize them with JSON.parse when getting them. (optional, default: true). This is useful if you are using types that ArangoDB doesn't support.
serialize Custom hook for serializing sessions to arangoDB. This is helpful if you need to modify the session before writing it out.
unserialize Custom hook for unserializing sessions from ArangoDB. This can be used in scenarios where you need to support different types of serializations (e.g., objects and JSON strings) or need to modify the session before using it in your app.
clear_interval The amount of milliseconds to wait between session accesses to clear expired sessions.
ttl ttl value in milliseconds used with clear_interval

The second parameter to the ArangoStore constructor is a callback which will be called once the database is ready.

Example

With express4:

var session = require('express-session');
var ArangoStore = require('connect-arango')(session);

app.use(session({
    secret: settings.cookie_secret,
    store: new ArangoStore({
      db : settings.db,
    })
  }));

With express<4:

var express = require('express');
var ArangoStore = require('connect-arango')(express);

app.use(express.session({
    secret: settings.cookie_secret,
    store: new ArangoStore({
      db: settings.db
    })
  }));

With connect:

var connect = require('connect');
var ArangoStore = require('connect-arango')(connect);

Removing expired sessions

Since ArangoDB does not have a TTL entry for documents, this is done using an AQL query in the session store. Every time a session is accessed, it will clear expired sessions, but only if it has passed more than clear_interval milliseconds (default 60 seconds) between each access.
