level-rpc v0.3.1

level-rpc

Super fast rpc mechanism for LevelUp

Status

• [X] stringify
• [X] parse
• [X] string encoding
• [ ] buffer encoding
• [ ] rpc server
• [ ] rpc client
• [ ] db#get(key, cb)
• [ ] db#put(key, value, cb)
• [ ] db#del(key, cb)
• [ ] db#batch(opts, cb)
• [ ] db#create*Stream()
• [ ] db#approximateSize()

Motivation

multilevel is nice but slow and doesn't support binary data. Instead of going after feature parity first this module is all about speed and binary support, feature parity with levelup will come later.
