Nosql database that works in memory only inherits from abstract-nosql
npm install nosql-memdb+ events-ex: hooked eventable ability.
+ the modularization(feature plugin) with abstract-nosql
* nosql-stream: streamable ability. you need implement the AbstractIterator.
* nosql-encoding: key/value encoding ability.
- (broken changes) remove the streamable feature from buildin. this is a plugin now.
- (broken change) defaults to disable asBuffer option.
* pls use the getBuffer method to get as buffer.
+ Add the AbstractError and error code supports.
+ Add the synchronous methods supports.
* see abstract-nosql to more details.
``js
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!
