GitHub - ericflo/node-jsonrpc: JSON-RPC client and server

This is a JSON-RPC server and client library for node.js <http://nodejs.org/>, the V8 based evented IO framework. Firing up an efficient JSON-RPC server becomes extremely simple: var rpc = require('jsonrpc'); function add(first, second) { return first + second; } rpc.expose('add', add); rpc.listen(8000, 'localhost'); And creating a client to speak to that server is easy too: var rpc = require('jsonrpc'); var sys = require('sys'); var client = rpc.getClient(8000, 'localhost. node-jsonrpc. This module makes it easy to process and respond to JSON-RPC (v1.0) messages. JSON-RPC is an extremely simple format to communicate between the client (for example browser) and the host (server). It's an easy way to run functions server side by providing the server the function name that needs to be executed and the params alongside with it. Server runs this function and returns the results for it node-jsonrpc2. JSON-RPC 2.0 server and client library, with HTTP (with Websocket support) and TCP endpoints. This fork is a rewrite with proper testing framework, linted code, compatible with node 0.8.x and 0.10.x, class inheritance, and added functionalities. Tools. Check jsonrpc2-tools for some nice additions to this module. Instal I am trying to call json-rpc call through request module of nodejs. json-rpc call is in following format. curl --user myusername --data-binary '{jsonrpc: 1.0, id:curltest, method: getreceivedbyaddress, params: [1D1ZrZNe3JUo7ZycKEYQQiQAWd9y54F4XZ, 6] }' -H 'content-type: text/plain;' http://127.0.0.1:8332

  1. JSON-RPC 2.0 doesn't define any transport-specific issues, since transport and RPC are independent. V1.0 defined that exceptions must be raised if the connection is closed, and that invalid requests/responses must close the connection (and raise exceptions). Named parameters added (see Example below
  2. In this tutorial we will build an API using Node.js and Express that retrieves data from Bitcoin Core. This tutorial is meant to be a starter for anyone looking to create Bitcoin applications wit
  3. Creating a Remote Node Server: Getting Started with Node.js: We can get stared by creating a new directory and then initializing npm (which was installed with Node). You will be asked to fill out a few items for the project such as the name, author, etc. These are completely optional, but recommended as best practice. Keep most items as their.
  4. JSON-RPC Server. Geth supports all standard web3 JSON-RPC APIs. You can find documentation for these APIs on the Ethereum Wiki JSON-RPC page. JSON-RPC is provided on multiple transports. Geth supports JSON-RPC over HTTP, WebSocket and Unix Domain Sockets. Transports must be enabled through command-line flags
  5. As such, the last piece is to implement a http server. This is the point where most of us would have wished to use express, but we don't want that, so we're going to use the http module that ships with node, and implement a very simple routing table around it. And, as expected, let's go ahead and create our server.js file. This is the file that sort of binds everything together, so we'll go.
  6. rpc-websockets is built on Node.js and supports both LTS and Current versions. Use the free OSS edition in order to implement and manage your own WebSocket server instances, or subscribe for our Pro plan and have us manage your instances and provide you with management of your methods, events and notifications on an easy-to-use Web Management portal

JSON-RPC is a HTTP- and/or raw TCP socket-based interface for communicating with Kodi. It replaces the deprecated HTTP API, and offers a more secure and robust mechanism in the same format. It is based upon the JSON-RPC 2.0 specification. Each method in the interface can have different security needs which means one client may be allowed to only control playback while another can only read and. Proxy client-server for Ethereum node using JSON-RPC interface. Why? Mostly popular cryptocurrencies usually are forks of Bitcoin and all of them support Bitcoin protocol for communication with their full nodes. Ethereum go hard by own way and made own API for that. This library is a proxy to Ethereum node which implement many API methods like in bitcoind. Also it have signals like blocknotify. If you are already happily connected to your Ethereum node, then you can skip the rest of the Providers section. This provider handles interactions with an HTTP or HTTPS based JSON-RPC server. endpoint_uri should be the full URI to the RPC endpoint such as 'https://localhost:8545'. For RPC servers behind HTTP connections running on port 80 and HTTPS connections running on port 443 the port. JSON-RPC and REST belong to Remote Procedure Call (RPC) category of the tech stack. Zalando, ScoreBeyond, and Eyasys are some of the popular companies that use REST, whereas JSON-RPC is used by Qurami, eleme, and TelebidPro. REST has a broader approval, being mentioned in 13 company stacks & 20 developers stacks; compared to JSON-RPC, which. The web3.js library is an Ethereum Javascript API which connects using the generic JSON-RPC spec.
