A node based JSON-RPC 2.0 server stub

JSON-RPC specification

• Uses node http currently to handle requests
• Includes method params validation
• Take a look at the example folder for implementation guide

Type Structure

{
  TypeName: {
    description: 'description of type',
    schema: {
      prop1: { type: Number },
      prop2: { type: String },
      ...
    }
  },
  ...
}

• TypeName should be capitalized
• schema follows structure from validate

Method Structure

{
  methodName: {
    description: 'method description',
    params: ['Type1',...],
    returns: ['Type2',...],
    exec: async (data) => {
      ...
    }
  },
  ...
}

• Types can be defined as in validate
• Types can as well be primitives such as

Number, String, Boolean, Array, Object

• TODO: treat array types with

Array<Type>

Usage

let http = require('http');

let RPC = require('rpc_stub');
// your methods
let methods = require('./methods');
// your types
let types = require('./types');
// authenticate
let authenticate = async (req) => {
  // request authentication code
}

let handler = new RPC(types, methods, authenticate); 
let server = http.createServer(handler.getListener());
const PORT = process.env.PORT || 9090;

server.listen(PORT);
console.log('listening on port',PORT);

TODO

• [x] Add parameter validation
• [ ] Add Unit Tests
• [ ] Add Response Validation
• [x] Add access control
