The ARN Client is a JavaScript API to include into your website to leverage Arianee web3 services, such as:

• Authentication: wallet connect, web3 modal, JWT signing
• Conditions: check if some token-based or database-based (or both) conditions are true. Includes NFT tag checks and whitelisting.
• NFT: simpler APIs for conditions (token gating, whitelists…), get NFT info (metadata).
• Data: read/write data stored in a project-specific, server-side database.
• Tracking: configure gathering of client-side events
• Internationalization (i18n): get translations of message keys.
• Logging to debug ARN behavior.

Setup

ARN Client is a library that requires a JavaScript runtime, so you’ll need to install Node.js then make sure to have a package.json describing your project (if you have none, create one), notably that it requires the ARN client packages, like below:

{
  "name": "myproject",
  "version": "0.1.0",
  "dependencies": {
		**"@arianee/arn-client": "^2.2.18",
    "@arianee/arn-types": "^2.2.18",**  
    "@wagmi/core": "1.0.6",  
****  }
}

Then you can run npm install.

<aside> 💡 ARN libraries are published are also available as beta/pre-release (suffixed with -staging-x) or alpha/under development (suffixed with -develop-x). It is recommended to use production versions only, however. Using staging or develop versions can imply bugs or breaking changes.

Creating the client

Import the [ArnClient](<https://arianee.github.io/arn/packages/arn-client/docs/classes/ArnClient.html>) class and instantiate through an [ArnClientFactory](<https://arianee.github.io/arn/packages/arn-client/docs/interfaces/ArnClientFactory.html>). Most of the time you’ll use an ArnHttpClientFactory because you’ll want to connect to an ARN Server:

const clientFactory = new ArnHttpClientFactory();

In any case, you’ll need to provide a configuration to provide to that client factory:

const arnClient = clientFactory.create(config);

Below is described how you can get such config.
