Example
var streamable = require('nosql-stream')
var eventable = require('events-ex/eventable')
var MemDB = eventable(streamable(require('nosql-memdb')))
var db = MemDB()
//eventable ability:
db.on('put', function(key, value){
console.log('put:', key, value)
})
db.open()
db.put('name', 'Yuri Irsenovich Kim')
db.put('dob', '16 February 1941')
db.put('spouse', 'Kim Young-sook')
db.put('occupation', 'Clown')
//streamable ability:
db.readStream()
.on('data', console.log)
.on('close', function () { console.log('Show\'s over folks!') })
Note in this example we're not even bothering to use callbacks on our .put()
methods even though they are async. We know that MemDOWN operates immediately so the data will go straight into the store.
Running our example gives:
{ key: 'dob', value: '16 February 1941' }
{ key: 'name', value: 'Yuri Irsenovich Kim' }
{ key: 'occupation', value: 'Clown' }
{ key: 'spouse', value: 'Kim Young-sook' }
Show's over folks!
