用法
有了 Fuels 依赖设置，现在你可以创建一个连接到 Fuel 提供程序并检索给定钱包地址的基本资产余额的 React 组件。以下是如何实现的示例：
import { BN, Provider, Wallet } from "fuels";
import { useEffect, useState } from "react";
function App() {
const [balance, setBalance] = useState(0);
useEffect(() => {
async () => {
const provider = await Provider.create("https://devnet.fuel.network/v1/graphql");
const myWallet = Wallet.fromAddress("0x...", provider);
myWallet.getBalances().then((data) => {
setBalance(new BN(data[0].amount).toNumber());
});
}()
}, []);
return <div>My Balance: {balance}</div>;
}
export default App;CDN 用法（仅限浏览器）
为了快速测试或仅仅是玩玩，你可以直接从我们的 CDN 在你的 Web 应用程序中加载它。
<script type="module">
import {
Wallet,
Provider,
} from "https://cdnjs.cloudflare.com/ajax/libs/fuels/0.89.1/browser.mjs";
const exec = async () => {
const provider = await Provider.create(
"https://devnet.fuel.network/v1/graphql",
);
const { name } = provider.getChain();
console.log(name);
};
exec();
</script>
