rpclibrary is a websocket on steroids!
npm i rpclibrary
import {Backend, Frontend} from 'rpclibrary'
const echo = (x) => x
const server = new Backend.RPCServer(20000, [{
name: 'HelloWorldRPCGroup',
exportRPCs: () => [
echo, //named function variable
function echof(x){ return x }, //named function
{
name: 'echoExplicit', //describing object
call: async (x) => x
}
]
}])
const client = new Frontend.RPCSocket(20000, 'localhost')
client.connect().then(async () => {
const r0 = await client['HelloWorldRPCGroup'].echo('Hello')
const r1 = await client['HelloWorldRPCGroup'].echof('World')
const r2 = await client['HelloWorldRPCGroup'].echoExplicit('RPC!')
console.log(r0,r1,r2) //Hello World RPC!
})
rpclibrary offers a special type of call that can be used with callbacks
import {Backend, Frontend, Utils} from 'rpclibrary'
const callbacks:Map<string, Function> = new Map()
const server = new Backend.RPCServer(20000, [{
name: 'HelloWorldRPCGroup',
exportRPCs: () => [
function triggerCallbacks(...messages){ callbacks.forEach(cb => cb.apply({}, messages)) },
{
name: 'subscribe',
hook: async (callback) => {
const resp = Utils.makeSubResponse()
callbacks.set(resp.uuid, callback);
return resp
}
},{
name: 'unsubscribe',
call: async (uuid) => { callbacks.delete(uuid) }
}
]
}])
const client = new Frontend.RPCSocket(20000, 'localhost')
client.connect().then(async () => {
const res = await client['HelloWorldRPCGroup'].subscribe(async (...args:any) => {
console.log.apply(console, args)
/* close the callbacks once you're done */
await client['HelloWorldRPCGroup'].unsubscribe(res.uuid)
client.unhook(res.uuid)
})
await client['HelloWorldRPCGroup'].triggerCallbacks("Hello", "World", "Callbacks")
})
