Atomic sessions for Koa.
- Currently uses MongoDB.
- Atomic updates - don't butcher the entire session.
- Don't grab the session from the database unless necessary.
- Better error handling.
- Includes CSRF token handling
## Usage
```js
// create the app
var app = koa()
// attach the session to the app
var MongoDBSession = require('koa-atomic-session')(app, {
maxAge: '1 month'
})
// asynchronously attach the collection
// you should not start the app until you do this
require('mongodb').MongoClient.connect('mongodb://localhost', function (err, db) {
if (err) throw err
// set the collection
MongoDBSession.collection = db.collection('sessions')
// ensure indexes every time!
MongoDBSession.ensureIndex()
})
// use it in your app
app.use(function* (next) {
var session = yield this.session()
yield session.unset('user_id')
yield session.set('user_id', new ObjectID()).then(session.update)
})
```
## API
### var Session = Session(app, [options])
Options:
- `key` - cookie key
- `maxAge` - default to 14 days
### this.session().then( session => )
Grab the session from the database asynchronously.
### session.touch().then( session => )
Updates the new `expires` time.
### session\[command\](arguments...).then( => )
Change properties of the session.
See database-specific options below.
### session.update().then( => )
Updates all the properties of the `session` object after running a command.
Should always be added to a `.then()`.
```js
yield session.set('message', 'hello')
.then(session.update)
assert.equal(session.message, 'hello')
```
### session.destroy.then( => )
Destroys the session without creating a new one.
### session.regenerate.then( session => )
Creates a brand new session.
### var csrf = session.createCSRF()
Create a CSRF token.
### session.assertCSRF(csrf)
Assert that a CSRF token is valid.
## MongoDB API
### MongoDBSession.ensureIndex().then( => )
Adds indexes on the `expires` property so that expires are automatically set.
### MongoDBSession.collection =
Set the collection asynchronously.
You should set this collection before starting your app.
### session\[command\](arguments...).then( => )
Supports most MongoDB properties.
This uses [mongodb-next](https://www.npmjs.com/package/mongodb-next) internally.
Some commands that are supported are:
- `.set(key, value)``
- `.unset(key)`
- `.rename(name, newName)`
- `.pull()`
- `.addToSet()`
