Practical overview

When it fits

Use it when building JavaScript software that needs Web3 interaction with Aion, especially when working with the documented AVM contract bindings.

Who it is for

  • JavaScript developers building applications that interact with the Aion network.
  • Developers working with AVM contracts who need method bindings, read-only calls, transactions, gas estimates or event logs.

Documented uses

  • Add Aion Web3 functionality to a Node.js application.
  • Build a browser bundle for use in an HTML-based application.
  • Create an interface from an AVM contract ABI and use it to call contract methods.
  • Request past AVM contract event logs or estimate gas for a method.
Before you choose

Requirements & limits

  • The README recommends Node.js 10.x or later and npm 6.x or later; other versions are not thoroughly tested according to the project.
  • The documented browser path produces dist/web3.min.js with Browserify, while the Node.js example initializes Web3 with an HTTP provider.
  • AVM binding notes say automatic binding is not included and warn that Java/JavaScript float conversion can change precision.
  • The repository identifies its license as GPL-3.0.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install Aion WEB3 in a Node.js project

Add the Aion Web3 package to a project using the README's documented npm setup.

Before you start

  • Node.js; version 10.x or later is recommended.
  • npm; version 6.x or later is recommended.

Steps

  1. Install the package with the command below.

    Documented command
    npm install --save aion-web3

  2. In Node.js code, require aion-web3 and create a Web3 instance with an HTTP provider.

Expected outcome

The project has the library installed and the README's documented pattern for initializing a Web3 instance.

Guide limitations

  • Other Node.js and npm versions may work, but the README says they have not been thoroughly tested.
  • The example provider URL is localhost; the README does not establish a network endpoint for other environments.

Prepare the browser bundle

Build the documented JavaScript bundle for inclusion in an HTML file.

Before you start

  • Node.js; version 10.x or later is recommended.
  • npm; version 6.x or later is recommended.

Steps

  1. Install the repository dependencies with the command below.

    Documented command
    npm install

  2. Run the command below to produce dist/web3.min.js.

    Documented command
    npm run browserify

  3. Include the generated file in the HTML file.

Expected outcome

A browser bundle is produced at `dist/web3.min.js` for inclusion in a web page.

Guide limitations

  • Other Node.js and npm versions may work, but the README says they have not been thoroughly tested.
