What is WyzthWeb?

Wyzth Web - Developer Document

WyzthWeb aims to deliver a unified, seamless development experience influenced by Ethereum's Web3 implementation. We have taken the core ideas and expanded upon it to unlock the functionality of TRON's unique feature set along with offering new tools for integrating DApps in the browser, Node.js and IoT devices.

Compatibility

• Version built for Node.js v6 and above
• Version built for browsers with more than 0.25% market share

You can access either version specifically from the dist folder.

WyzthWeb is also compatible with frontend frameworks such as:

• Angular
• React
• Vue.

You can also ship WyzthWeb in a Chrome extension.

Installation

Node.js

npm install wyzthweb

or

yarn add wyzthweb

Browser

First, don't use the release section of this repo, it has not updated in a long time.

Then easiest way to use WyzthWeb in a browser is to install it as above and copy the dist file to your working folder. For example:

cp node_modules/wyzthweb/dist/WyzthWeb.js ./js/wyzthweb.js

so that you can call it in your HTML page as

<script src="./js/wyzthweb.js"><script>

Testnet

Shasta is the official Tron testnet. To use it use the following endpoint:

https://api.shasta.trongrid.io

Get some Shasta WYZ at https://www.trongrid.io/shasta and play with it. Anything you do should be explorable on https://shasta.tronscan.org

Your local private network for heavy testing

You can set up your own private network, running Tron Quickstart. To do it you must install Docker and, when ready, run a command like

docker run -it --rm \
  -p 9090:9090 \
  -e "defaultBalance=100000" \
  -e "showQueryString=true" \
  -e "showBody=true" \
  -e "formatJson=true" \
  --name tron \
  trontools/quickstart

Creating an Instance

First off, in your javascript file, define WyzthWeb:

const WyzthWeb = require('wyzthweb')

The easiest way to instantiate wyzthWeb is to run

const wyzthWeb = new WyzthWeb({
    fullHost: 'https://api.trongrid.io',
    privateKey: '...'
})

but you can continue to use the old way:

const wyzthWeb = new WyzthWeb(fullNode, solidityNode, eventServer, privateKey)

Valid alternatives are:

const wyzthWeb = new WyzthWeb({
    fullHost: 'https://api.trongrid.io',
    eventServer: 'https://api.someotherevent.io'
  },
  privateKey: '...'
)

where fullHost defines fullNode and solidityNode while the eventServer is specified, and the privateKey is passed separately.

const wyzthWeb = new WyzthWeb({
    fullNode: 'https://api.trongrid.io',
    solidityNode: 'https://api/somesolidity.io'
    eventServer: 'https://api.somevent.io',
    privateKey: '...'
  }
)

similar to the old approach

A full example

The better way to understand how to work with Tron is to clone the MetaCoin example and follow the instructions at https://github.com/Tronbox-boxes/metacoin-box

Recent History

2.3.1

• Adds support for not-tld domain, like http://localhost
• Improve the new format, allow passing the privateKey as a property in the option object

2.3.0

• Introduces new format to instantiate wyzthWeb, passing an options object instead that fullNode, solidityNode and eventServer as separate params
• Fixes bug in _watch which causes an ethernal update of the since parameter
