Installation

Install

To install

npm install @cityofzion/neon-js

or

npm install @cityofzion/neon-core

This will give you the release that is compatible for the neo3 mainnet and testnet.

Note For most use-cases, we recommend neon-js. Do not use neon-js and neon-core in the same project. The classes are not cross-package compatible. See https://github.com/CityOfZion/neon-js/issues/850.

Node

Support policy is to support the maintenance and LTS versions of Node. At the time of writing, this is:

• Node 20
• Node 22

Web

Both neon-core and neon-js are packaged for the web. Use script tags:

<script src="https://unpkg.com/@cityofzion/neon-js@next"></script>

The library will be loaded under the variable Neon.
