Network selector

If your application can switch between Mainnet and Testnet networks you may want to add the network selector widget to the navigation bar.

Network selector set up

Define an array with the list of networks your application supports:

export const NETWORKS = ['Mainnet', 'Testnet'];

Create a state value to store the current network. For example, with useState() hook, but you can use any other method.

const [network, setNetwork] = useState<string>(NETWORKS[1]);

Define a networkSettings object with the list of networks, the current network, and a callback method to handle network selection by the user. Add this object to the topBarSettings prop in the <ClickUI> component:

const networkSettings = {
  networks: NETWORKS,
  currentNetwork: network,
  onNetworkSwitch: (n: string) => { setNetwork(n); },

Customize the network icons

You can also specify your custom icons for each of the networks:

import mainnetIcon from './assets/ico-mainnet.svg'
import testnetIcon from './assets/ico-testnet.svg'

const NETWORKS = [
  { title: 'Mainnet', icon: mainnetIcon },
  { title: 'Testnet', icon: testnetIcon }
