    level-live-stream

    Stream live changes from levelup.

    Build Status

    Works just like LevelUp#readStream except instead of ending, it will stay open and stream changes to the database as they are inserted!

    Just like the couchdb changes feed, but for any arbitrary range of keys!

    see also, level-livefeed for the same idea, but with a streams2 api.

     
    var level = require('level')
     
    level('/tmp/level-live-stream', 
      {createIfMissing: true}, function (err, db) {
     
      var liveStream = require('level-live-stream')(db)
     
      liveStream
        .on('data', console.log)
     
      setInterval(function () {
        db.put('time', new Date().toString())
     
      }, 1000)
     
    })
     

    You can also attach liveStream as a method to the db like below. This will allow multilevel clients to use db.liveStream().

    var LiveStream = require('level-live-stream');
     
    // attach the `liveStream` method using `install`
    LiveStream.install(db);
     
    // then invoke the method using the `db` instance
    db.liveStream()
      .on('data', console.dir);

    options

    LiveStream(db, {
      tail: true,   //follow
      old : true,   //get old records from data base
                    //if old=false you will only get live updates
      min : loKey,  //lowest key in range
      max : hiKey,  //highest key in range
      reverse: true //stream in reverse (only applies to old records)
    })
