Jobs must be idempotent! If the process crashes before job has calledback, it will be rerun the next time it's started, for consistency!

Stability

Stable: Expect bugfixes.

Example

vardb=require('levelup')('/tmp/level-trigger-example')varSubLevel=require('level-sublevel');SubLevel(db)//MUST install sublevel.varTrigger=require('level-trigger')vartrigDb=Trigger(db,'example',function(ch){//optionally index the job with a different key.//if there are two jobs with the same key,//it will only be triggered once.returnch.key},function(value,done){//call done when job is done.done()}})//if you want, start the trigger in batch mode.//this will process all the keys in the input db.//otherwise, jobs will be processed whenever a key is inserted!if(require('optimist').argv.batch)trigDb.start()
