Yet another JSON RPC (Client)

Example

let Yajrpc = require('yajrpc')
let rpc = new YajRPC({
  url: 'http://localhost:8332',
  user: process.env.RPCUSER,
  pass: process.env.RPCPASSWORD
})
 
// 1 call
rpc.call('func1', [1, 2, 3], (err, result) => {
    // ...
})
 
// batched request
rpc.batch([{
    method: 'func1',
    params: [1, 2, 3],
    callback: (err, result) => {
        // ...
    }
}, ...], function (err) { ... })

The batch method is remarkably useful in high-performance applications when used with tools like qup:

let qup = require('qup')
let Yajrpc = require('yajrpc')
 
let client = new Yajrpc({
  url: process.env.RPC,
  user: process.env.RPCUSER,
  pass: process.env.RPCPASSWORD
})
 
// group RPC calls into batches of RPCBATCHSIZE, with a maximum of RPCCONCURRENT batches simultaneously
let q = qup((batch, callback) => {
  client.batch(batch, callback)
}, process.env.RPCCONCURRENT, process.env.RPCBATCHSIZE)
 
function rpc (method, params, callback) {
  q.push({ method, params, callback })
}
 
rpc('func1', [1, 2, 3], ...)

See yajrpc/qup for a pre-made equivalent of the above.
