remote API for levelUP

LEVELNET

Remote API bindings for LevelUP

A replication of the LevelDB API on the client. Full API coverage using battle hardened mux-demux and dnode to provide the streaming RPC mechanism. Create a LevelUP instance, pass it to a Levelnet server function and get a duplex stream to pipe into. The client() function returns a stream which also has the full levelUP API integrated.

Another module, multilevel, exists and provides the same functionalityas levelnet - though levelnet uses dnode whereas multilevel uses rpc-stream. If in doubt use multilevel - it has been around longer and does some extra stuff that might be useful. I also changed levnet's API to match multilevel so you can just drop in either and they'll work.

  stream.pipe(lev).pipe(stream)
}
