node-simple-rpc

Very simpe and minimal library and examples for nodejs RPC via HTTP and JSON in study manner.

Concept

It is very simple to implement RPC library when a language and its library have its serializer (including serializable memory model) like JSON serializer and a simple network framework like HTTP client and server.

nodejs is very easy to implement a simple RPC library because,

Because of JSON.stringify and JSON.parse, we don't be worried about serialization.
Because of express and fetch, we don't be worried about how to carry them via network.

Please see details in lib directory.

Library

lib/proxy.js will make your interface to communicate with an actual method in server.
lib/rpc.js will export your server procedures to communicate with a proxy method in client.

Usage

Server

const rpc = require('./lib/rpc');
rpc(/* port-number = */ 3000, {
  add: (a, b) => a + b,
});

Client

const proxy = require('./lib/proxy')('http://localhost:3000')({
  add: (a, b) => 0,
});
proxy.add(10, 20).then(console.log);

Example
