I recommend to use racer-model-rpc instead of the current package
Racer/Derby plugin for enabling RPC
After adding the plugin:
racer.use(require('racer-rpc'));
Use it below API:
On server:
// With callback
var backend = racer.createBackend(...);
backend.rpc.on('rpc-with-callback', function (arg1, arg2, cb) {
arg1 === 'arg1' // true
arg2 === 'arg2' // true
cb(null, 'arg3', 'arg4');
});
// Without callback
backend.rpc.on('rpc-without-callback', function (arg1, arg2) {
arg1 === 'arg1' // true
arg2 === 'arg2' // true
});
On client:
// With callback
model.call('rpc-with-callback', 'arg1', 'arg2', function (err, arg3, arg4) {
arg3 === 'arg3' // true
arg4 === 'arg4' // true
});
// Without callback
model.call('rpc-withour-callback', 'arg1', 'arg2');
