@openzeppelin/contracts-ui-builder-react-core
This package provides core React Context providers and hooks for the OpenZeppelin Contracts UI Builder ecosystem. It centralizes the management of global wallet state, active network selection, active adapter instances, and the consumption of adapter-specific UI capabilities (like facade hooks and UI context providers).
It is a foundational package intended to be used by the main @openzeppelin/contracts-ui-builder-app application and can also be leveraged by exported standalone applications to ensure consistent wallet and adapter integration patterns.
Core Responsibilities
- Adapter Instance Management: Provides
AdapterProvider which maintains a registry of ContractAdapter instances, ensuring only one instance exists per network configuration (singleton pattern).
- Global Wallet/Network State Management: Provides
WalletStateProvider which builds upon AdapterProvider to manage:
- The globally selected active network ID and its corresponding
NetworkConfig.
- The active
ContractAdapter instance for this global network and its loading state.
- The
EcosystemSpecificReactHooks (facade hooks) provided by the active adapter.
- Orchestration of rendering the active adapter's UI context provider (e.g.,
WagmiProvider for EVM adapters), which is crucial for the functionality of facade hooks.
- Consistent State Access: Exports consumer hooks
useAdapterContext() and useWalletState() for components to access this managed state and functionality.
Key Exports
- Providers:
AdapterProvider: Manages adapter instances. Requires a resolveAdapter prop to fetch/create adapters.
WalletStateProvider: Manages global active network/adapter/wallet state. Requires a getNetworkConfigById prop and is typically nested within an AdapterProvider.
- Contexts (Primarily for advanced use or typing):
AdapterContext
WalletStateContext
- Hooks:
useAdapterContext(): To access AdapterProvider's getAdapterForNetwork function.
useWalletState(): To access global state like activeNetworkId, activeAdapter, walletFacadeHooks, and the setActiveNetworkId dispatcher.
- Types:
AdapterProviderProps
WalletStateProviderProps
AdapterContextValue, AdapterRegistry
WalletStateContextValue
Installation
This package is typically used as a workspace dependency (e.g., "@openzeppelin/contracts-ui-builder-react-core": "workspace:^") within the Contracts UI Builder monorepo.
It has peer dependencies on react and react-dom, and direct dependencies on @openzeppelin/contracts-ui-builder-types and @openzeppelin/contracts-ui-builder-utils.
Usage Example (Application Setup)
import {
AdapterProvider,
WalletStateProvider,
} from '@openzeppelin/contracts-ui-builder-react-core';
import { getAdapter, getNetworkById } from './core/ecosystemManager';
function AppRoot() {
return (
<AdapterProvider resolveAdapter={getAdapter}>
<WalletStateProvider
initialNetworkId="ethereum-mainnet" // Optional: Set a default active network
getNetworkConfigById={getNetworkById}
>
{/* Your application components that can now use useWalletState() */}
</WalletStateProvider>
</AdapterProvider>
);
}
Consuming Global State in Components
import { useWalletState } from '@openzeppelin/contracts-ui-builder-react-core';
function MyWalletComponent() {
const {
activeNetworkId,
activeNetworkConfig,
activeAdapter,
isAdapterLoading,
walletFacadeHooks,
setActiveNetworkId,
} = useWalletState();
if (isAdapterLoading || !activeAdapter) {
return <p>Loading wallet information...</p>;
}
const accountInfo = walletFacadeHooks?.useAccount ? walletFacadeHooks.useAccount() : null;
const isConnected = accountInfo?.isConnected;
return (
<div>
<p>Current Network: {activeNetworkConfig?.name || 'None'}</p>
<p>Wallet Connected: {isConnected ? 'Yes' : 'No'}</p>
{/* Further UI using adapter or facade hooks */}
</div>
);
}
This package aims to decouple the builder application logic from the direct management of adapter instances and their UI contexts, promoting a cleaner and more maintainable architecture.
