Browser client

Create this client only after your server returns a connection ID and connection-scoped access token.

import { createDomain0Client } from 'domain0'

const client = createDomain0Client({
  baseUrl: '/api/domain0/',
  token: async () => getCurrentConnectionToken(),
})

The recommended baseUrl is a same-origin bridge in your application. That keeps browser requests first-party while the token remains bound to your exact origin. See the Next.js guide.

Usually, open the dialog

Pass this client to domain0.connectDomain(). The dialog selects the right provider and setup operation for the saved connection state.

const { connection } = await client.getConnection(connectionId)

if (connection.state === 'active') {
  console.log(`${connection.intent.domain} is connected`)
}
