Isomorphic-Rpc

Exposes a Javascript object that maps all methods to RPC calls using Promises"

Web3.js Has Some Issues

• Mostly it's huge
• It doesnt follow the spec (i.e. spec has eth_getBlockByHash, web3 has only getBlock)
• It randomly prints some values as hex string ("0x1234") while others com back as number and for some odd reason block.difficulty is returned as a string of decimal digits (lol WAHT?)
• New RPC methods like getProof are not supported (in web3 or other libraries) until each piece of software in the chain publishes a feature update to support it.

Solution

Using Ecmascript's new Proxy functionality you can create an object such that when you call a missing method on it, it instead calls a "handler" function that has access to the method name called.

The library uses this to automatically create an RPC request from any method name given. So any brand new or experimental RPC method your client software supports will be exposed.

Extremely Lightweight

The module is 37 lines of code. There is only 1 dependency (which branches into 3 small packages). It enables the library to be:

Isomorphic

The use of this library should work identically in both Node and all desktop/mobile Browsers (except Internet Explorer)

Also

This should probably work on all Javascript RPC applications because of its agnosticism to the actual methods being called.

But I haven't tried that yet so let me know!
