# Connex

Connex is the standard interface to connect dApps with VeChain blockchain and users. Aiming to help developers building decentralized applications.

# Installation

Installing connex into your web-based applications.

# Include in <script> tag

Just include the CDN link within a script tag. Connex will then be registered as a global variable.

<!-- install the latest v2 -->
<script src="https://unpkg.com/@vechain/connex@2" />


It's recommended when your project is a bit large.

npm i @vechain/connex
import Connex from '@vechain/connex'

# Setup

# Create a Connex object connects to VeChain mainnet

const connex = new Connex({
    node: 'https://mainnet.veblocks.net/', // veblocks public node, use your own if needed
    network: 'main' // defaults to mainnet, so it can be omitted here

# Connect to testnet

const connex = new Connex({
    node: 'https://testnet.veblocks.net/',
    network: 'test'

# Or connect to a private network

const connex = new Connex({
    node: '<the API url of your node>',
    // the genesis block of your private network
    network: {
        id: '0x...',

# Create Vendor module only

In some cases, e.g. the classic 'Buy me a coffee' (opens new window) demo, you don't need the ability to access the blockchain. You can opt-out Connex.Thor module, and just create Connex.Vendor module.

const vendor = new Connex.Vendor('main') // 'main','test' or genesis ID if it's private network

# Using in Node.js environment

This package, @vechain/connex is designed only working in browser, if you are interested running it in Node.js, try @vechain/connex-framework (opens new window).

# Playground

Package @vechain/connex-repl (opens new window) provides a quick way to try out connex interface.
