Integrate Vanilla JS application

In this tutorial, you will learn how to integrate a vanilla JS application with the Arcana Auth SDK to enable user onboarding and signing of blockchain transactions via the embedded Web3 Arcana wallet.

Note

Refer to these code samples for integrating your React/Next.js or Vue application with the Arcana Auth SDK:

React
Vue

Try Auth Example

Prerequisites

Developers must first log into the Arcana Developer Dashboard: https://dashboard.arcana.network
Use the dashboard to register and configure application settings for using the Auth SDK. Click on the Auth tab in the dashboard. Configure the application settings as per the required user onboarding experience. Choose and configure from a list of supported authentication mechanisms:
- Discord
- GitHub
- Google
- Twitch
- Twitter
Tip

You may be required to configure additional details depending on the choice of authentication mechanisms. For example, if the application wants to enable users to onboard using the Google social authentication then the developer must set up and specify the clientID for Google OAuth.

For details, see how to configure one or more social logins.
Save the App Address assigned to the application. It is displayed on the dashboard application page and required to instantiate the AuthProvider while integrating the application.

Steps

Integrating your application with the Auth SDK is simple!

Follow these two steps:

Step 1: Install Auth SDK

npm

npm install --save @arcana/auth

yarn

yarn add @arcana/auth

CDN

<script src="https://cdn.jsdelivr.net/npm/@arcana/auth"></script>
<script src="https://unpkg.com/@arcana/auth"></script>

Step 2: Initialize the Auth SDK

Import Arcana Auth SDK and create a 'new' AuthProvider. During instantiation of the AuthProvider, specify the unique App Address value assigned to your application after registering and configuring using the dashboard. Also, specify the Arcana wallet visibility mode via the alwaysVisible parameter.

const { AuthProvider } = window.arcana.auth // From CDN
//or
import { AuthProvider, CHAIN } from '@arcana/auth' //From npm

const appAddress = '445007f942f9Ba718953094BbeeeeeB9484cAfd2' // App Address Example

const auth = new AuthProvider(`${appAddress}`, {
  position: 'left', // defaults to right
  theme: 'light', // defaults to dark
  alwaysVisible: false, // defaults to true which is Full UI mode
  chainConfig: {
    chainId: CHAIN.POLYGON_MAINNET,
    rpcUrl: '',
  },
})

Initialize the newly instantiated AuthProvider.

try {
  await auth.init()
} catch (e) {
  // Handle exception case
}

Before you call any other Auth SDK functions, make sure initialization function is successful.

// After successful initialization, use AuthProvider functions
// For e.g., if you are building user login UI, when user
// chooses to log in via UI, call loginWithSocial function.

const arcanaProvider = await auth.loginWithSocial('google')

// If you are using ethers, you can access provider as shown below:

const provider = new ethers.providers.Web3Provider(arcanaProvider)

// If you are using web3js, then access the provider as shown below:

const provider = new Web3(arcanaProvider)

Caution

The application must wait until the initialization is complete, before invoking any of the other Auth SDK functions such as triggering user login, encryption/decryption, obtaining public keys, etc.

That is all!

You have successfully integrated your application with the Auth SDK and can invoke any supported functions.

What's Next?

After integrating with the Arcana Auth SDK, an application can onboard users through social authentication and passwordless login. The application users can utilize the embedded Arcana wallet to sign blockchain transactions, transfer or send blockchain tokens, etc.
