XDC3 - XinFin JavaScript API

This is the XinFin [JavaScript API][docs] which connects to the Generic JSON RPC spec.

You need to run a local or remote Ethereum node to use this library.

Please read the [documentation][docs] for more.

Installation

Node

npm install xdc3

Yarn

yarn add xdc3

Meteor

Note: works only in the Browser for now. (PR welcome).

meteor add ethereum:xdc3

In the Browser

Use the prebuild dist/xdc3.min.js, or build using the [xdc3.js][repo] repository:

npm run-script build

Then include dist/xdc3.js in your html file. This will expose XDC3 on the window object.

Usage

// in node.js
var Web3 = require('xdc3');
 
var web3 = new Web3('ws://localhost:8546');
console.log(web3);
> {
    eth: ... ,
    shh: ... ,
    utils: ...,
    ...
}

Additionally you can set a provider using web3.setProvider() (e.g. WebsocketProvider)

web3.setProvider('ws://localhost:8546');
// or
web3.setProvider(new Web3.providers.WebsocketProvider('ws://localhost:8546'));

There you go, now you can use it:

web3.eth.getAccounts()
.then(console.log);

Usage with TypeScript

Type definitions are maintained at DefinitelyTyped by others. You can install them with

npm install --dev @types/web3.js

You might need to install type definitions for bignumber.js and lodash too.

And then use web3.js as follows:

import Web3 = require("xdc3"); // Note the special syntax! Copy this line when in doubt!
const web3 = new Web3("ws://localhost:8546");

Please note: We do not support TypeScript ourselves. If you have any issue with TypeScript and web3.js do not create an issue here. Go over to DefinitelyTyped and do it there.

Building

Requirements

• Node.js
• npm

sudo apt-get update
sudo apt-get install nodejs
sudo apt-get install npm

Building (gulp)

Build only the web3.js package

npm run-script build

Or build all sub packages as well

npm run-script build-all

This will put all the browser build files into the dist folder.

Testing (mocha)

npm test
