Mole-RPC is a tiny transport agnostic JSON-RPC 2.0 client and server which can work both in NodeJs, Browser, Electron etc.

This is EventEmitter based tranport but there are [many more transports](https://www.npmjs.com/search?q=keywords:mole-transport). 

## Usage example

```js

const MoleClient = require('mole-rpc/MoleClient');

const MoleServer = require('mole-rpc/MoleServer');

const EventEmitterTransportClient = require('mole-rpc-transport-eventemitter/TransportClient');

const EventEmitterTransportServer = require('mole-rpc-transport-eventemitter/TransportServer');

const EventEmitter = require('events');

async function main() {

  const emitter = new EventEmitter();

  await runServer(emitter);

  await runClients(emitter);

}

async function runServer(emitter) {

  const server = new MoleServer({

    transports: [

      new EventEmitterTransportServer({

        emitter,

        inTopic: 'fromClient1',

        outTopic: 'toClient1'

      }),

      new EventEmitterTransportServer({

        emitter,

        inTopic: 'fromClient2',

        outTopic: 'toClient2'

      })

    ]

  });

  server.expose({

    getGreeting(name) {

      return new Promise((resolve, reject) => {

        setTimeout(() => {

            resolve(`Hi, ${name}`);

        }, 1000);

      });

    }

  });

}

async function runClients(emitter) {

  const client1 = new MoleClient({

    transport: new EventEmitterTransportClient({

      emitter,

      inTopic: 'toClient1',

      outTopic: 'fromClient1'

    })

  });

  const client2 = new MoleClient({

    transport: new EventEmitterTransportClient({

      emitter,

      inTopic: 'toClient2',

      outTopic: 'fromClient2'

    })

  });

  console.log('FROM CLIENT 1', await client1.callMethod('getGreeting', 'User1'));

  console.log('FROM CLIENT 2', await client2.callMethod('getGreeting', 'User2'));

}

main();

```
