Getting started

Network switcher provides a way for handling app network switching (both evm and cardano) chains.

Exports

{
  NetworkIcon
  NetworksDropdown,
  INetworkSwitcher,
  NetworkSwitcher,
  NetworkSwitcherContext,
  NetworkSwitcherContextProvider,
}

NetworkIcon

will render the passed network object icon by prop chainInfo which is type of INetworkOption.

this code snippet will render the current selected chain icon

import {
  NetworkIcon,
  NetworkSwitcherContext,
} from "@dcentralab/wc-network-switcher";

const { networkInfo } = useContext(NetworkSwitcherContext);
<NetworkIcon chainInfo={networkInfo} />;

NetworksDropdown

will render a list of networks staked over each other and highlight on the selected one.

it's internally used in NetworkSwitcher

import {
  NetworkIcon,
  NetworkSwitcherContext,
} from "@dcentralab/wc-network-switcher";

function NetworkSwitcher({ children }: INetworkSwitcher) {
  const { networksList } = useContext(NetworkSwitcherContext);
  return(
    <InlineModal
      onToggle={setDropdownOpened}
      closeOnContentClick
      content={<NetworksDropdown />}
    >
      {children}
    </InlineModal>)

NetworkSwitcherContextProvider

App should be wrapped with NetworkSwitcherContextProvider and used networks will be passed to it.

import { NetworkSwitcherContextProvider } from "@dcentralab/wc-network-switcher";

<NetworkSwitcherContextProvider networks={appNetworks}>
  <App />
</NetworkSwitcherContextProvider>;

NetworkSwitcher

the main UI component for switching network. located in header and been added to duf header beside the wallet connect component

Note: it's hidden on mobile

import { NetworkSwitcher } from "@dcentralab/wc-network-switcher";

<div className="duf-header-wallet-container">
  <NetworkSwitcher />
  {walletComponent}
  <ContextMenu links={menuLinks} rtl profileImage={profileImage} />
</div>;
