express-rethinkdb-store
A (currently basic) implementation of a RethinkDB Session Store.
It's a complete rewrite based on express-session-rethinkdb
.
Usage
Install and save Package with
npm install --save express-rethinkdb-store
then, assuming your express
app is in app
const session = require("express-session")
const RethinkStore = require("express-rethinkdb-store")
const store = new RethinkStore()
app.use(session({
secret: "supersecret",
cookie: "connect.sid",
store: store,
resave: false,
saveUninitialized: false
}))
Features
- Completely written in ES6 / ES.next
- Highly readable (See RethinkStore.js)
- Data is loaded directly from database, so no stale data in a local cache
- A cache utilizing RethinkDBs changefeeds is on the roadmap
- RethinkDB can't natively expire documents, so we remove expired sessions automatically after
flushInterval
milliseconds (60s by default). When a session gets requested it's expiry is automatically checked and, if expired, the session is removed.
API
Example with default values
new RethinkStore({
connectionOptions: {}, // See: https://www.rethinkdb.com/api/javascript/#connect
table: "session", // Session table
sessionTimeout: 86400000, // Session timeout in milliseconds
flushInterval: 60000 // Interval to delete expired sessions from database
})
Internals
callback_decorator
Used to wrap the modern async/await functions (async functions that return a promise instead of using callbacks).
// ES.next Syntax!
class RethinkStore extends session.Store {
@callback_decorator
async destroy(sid) {
await r.table(this.table).get(sid).delete()
}
}
After decoration destroy
accepts a second parameter cb
. This is required because express-session
uses
callback-style
