changes-feed

Basic changes-feed implementation that runs on top of leveldb

npm install changes-feed

build status

Usage

var changes = require('changes-feed')
var feed = changes(db) // db is a levelup
 
feed.createReadStream({live:true})
  .on('data', function(data) {
    console.log('someone appended:', data)
  })
 
feed.append('hello')

API

feed.append(value)

Append a new value to the changes feed. The value should be a string or buffer

stream = feed.createReadStream([options])

Stream out entries from the log. Per default this will stream out all entries. Options include:

{
  live: true,   // keep the stream open,
  since: number // only get changes >number
}

A stream data object looks like this

{
  change: number, // incrementing change number
  value: value    // the value appended
}
