A super simple RPC, connect client and server with the least possible code!
NO dependency, NO schema, NO config, just define functions and CALL!
// On Server
const srpc = require('./server-node.js')
srpc() // start server
srpc.add = (x, y) => x + y
// -------------------------------------
// On Client
import srpc from './client-es.js'
srpc('http://localhost:11111/') // server endpoint
console.log(await srpc.add(1, 2)) // 3export functions to be called by clients
const srpc = require('./server-node.js')
srpc() // listen on port 11111 by default
// the following methods are exported
srpc.test = () => 'Hello, world!'
srpc.add = (x, y) => x + y
// function can be nested!
srpc.calc = {}
srpc.calc.sqrt = x => Math.sqrt(x)const srpc = require('./server-fc.js')
// the following methods are exported
srpc.test = () => 'Hello, world!'
srpc.add = (x, y) => x + y
srpc.calc = {}
srpc.calc.sqrt = x => Math.sqrt(x)
// entrance
exports.handler = srpc()call functions on server and get the return value
Add script to <head>
<script src="https://cdn.jsdelivr.net/gh/yzITI/srpc@main/client.js"></script>OR copy client-es.js into your ESM project:
import srpc from './client-es.js'// initialize with endpoint
srpc('http://localhost:11111/')
// just call the functions!
srpc.test() // Promise -> 'Hello, world!'
srpc.add(1, 2) // Promise -> 3
srpc.calc.sqrt(2) // Promise -> 1.4142135623730951const srpc = require('./client-node.js')
// initialize with endpoint
srpc('https://matrix.yzzx.org/srpc')
srpc.test() // Promise -> 'Hello, world!'
srpc.add(1, 2) // Promise -> 3
srpc.calc.sqrt(2) // Promise -> 1.4142135623730951The following request and response model are used with http POST method and 'Content-Type': 'application/json'.
Request {
N: 'function.name', // function name
A: [1, 2, 3] // args in order
}
Response {
R: {} // return value
}
// Context data model used in hooks
Context {
N, A, R,
IP: String, // request IP
F: Function
}// node-srpc
srpc(hooks = {
before: Context => {}, // abort if assign Context.R
after: Context => {}
}, port = 11111)
// fc-srpc
srpc(hooks = {
before: Context => {}, // abort if assign Context.R
after: Context => {}
