Readme
:warning: This project is deprecated. We are no longer actively developing new features nor addressing issues. Read here for more info, and reach out if you are interested in taking over maintenance. We suggest looking into web3-react for a popular alternative to this project.
One line access to Web3 in your dApp.
npm install @openzeppelin/network
Import the library:
import { useWeb3Injected, useWeb3Network, useEphemeralKey } from '@openzeppelin/network/react';
Get Web3Context with React Hooks inside functional component:
const injected = useWeb3Injected();
const local = useWeb3Network('http://127.0.0.1:8545');
Use Web3Context
to get fresh data:
const { accounts, networkId, networkName, providerName, lib, connected } = web3Context;
Network.js will re-render component when network, accounts or connetion state change.
To use GSN with any hook specify GSN as an option, providing a signing key:
const local = useWeb3Network('http://127.0.0.1:8545', {
gsn: { signKey: useEphemeralKey() }
});
Import the library:
import { fromInjected, fromConnection } from '@openzeppelin/network';
Get Web3Context
:
const injected = await fromInjected();
const local = await fromConnection('http://127.0.0.1:8545');
To use GSN include a gsn
option, including a signing key:
const local = await fromConnection('http://127.0.0.1:8545', {
gsn: { signKey: ephemeral() }
});
Use Web3Context
to get fresh data immediately:
const { accounts, networkId, networkName, providerName, lib, connected } = web3Context;
Subscribe to events to get notified:
function updateNetwork(networkId, networkName) {}
function updateAccounts(accounts) {}
function updateConnection(connected) {}
web3Context.on(Web3Context.NetworkIdChangedEventName, updateNetwork);
web3Context.on(Web3Context.AccountsChangedEventName, updateAccounts);
web3Context.on(Web3Context.ConnectionChangedEventName, updateConnection);
Unsubscribe from events once you don't need them:
web3Context.off(Web3Context.NetworkIdChangedEventName, updateNetwork);
web3Context.off(Web3Context.AccountsChangedEventName, updateAccounts);
web3Context.off(Web3Context.ConnectionChangedEventName, updateConnection);
npx @openzeppelin/cli unpack gsn
