Awesome
YAJRPC
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.
