NPM Version NPM Downloads Node

Implementation of the session storage in Apache Cassandra as an extension of the express-session middleware. This version has been fully updated to ES6 and Node.js >= 6.0.0. For backwards compatibility, use older versions of the package.

Installation

$ npm install [-g] cassandra-store

Options

{
    "table": "sessions",
    "client": null,
    "clientOptions": {
        "contactPoints": [ "localhost" ],
        "keyspace": "tests",
        "queryOptions": {

   sid text,
   session text,
   expires timestamp,
   PRIMARY KEY(sid)
);
