Basic changes-feed implementation that runs on top of leveldb
npm install changes-feed
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')
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
}
