rpc-buddy v1.2.6

RPC Buddy

RPC Buddy allows me to automatically expose back-end Javascript methods for use by browser frontend code.

Never again do I have to write a single line of "fetch" code!!

I attach this single class to my Express setup, specify which classes and methods to expose and BAM! My methods are accessible! On the frontend, I just import a dynamically generated client and start making direct identical calls to my methods.

An Example

Say I have a backend class like so:

class someClass
{
  static someFunction(p1, p2, p3)
  {
    return p1 + ", " + p2 + ", " + p3;
  }
}

I integrate RPC Buddy with Express and specify which methods to expose like so:

const rpcBuddy = require('./RPC_Buddy');
const someClass = require('./someClass');

new rpcBuddy
(
  expressApp, 
  '/serverUrl', '/clientUrl', // backend endpoints
  [someClass], // classes to expose
  [{name: "someClass.someFunction"}] // class methods to expose
);

In my browser code I can, straight away, make backend calls like so:

import someClass from "/clientUrl?class=someClass";

window.onload = main;
async function main()
{
  const res = await someClass.someFunction("one", "two", "three");
  alert(res); // will show "one, two, three"
}
