2. Quote API Hooks: Contains hooks that allow your application to interact with the quote API, facilitating the discovery of efficient trading routes, akin to what's offered by 1inch.
3. Sui-coin-list API Hooks: Includes hooks to interact with the sui-coin-list API, simplifying the process of fetching coin data from Sui.

Installation

To install the @umi-ag/swap-widget library, run the following command in your project's root directory:

npm install @umi-ag/swap-widget
# or yarn
yarn add @umi-ag/swap-widget
# or pnpm
pnpm add @umi-ag/swap-widget

Usage

Swap Interface

import { UmiSwapWidget } from "./components/Swap";
import { JsonRpcProvider, mainnetConnection } from "@mysten/sui.js";

function App() {
  const { currentAccount, currentWallet } = useWalletKit();
  const provider = new JsonRpcProvider(mainnetConnection);

  /**
   * You need to pass these props to the UmiSwapWidget component:
   *
   * type SwapWidgetProps = {
   *    accountAddress?: string;
   *    wallet?: {
   *       signAndExecuteTransactionBlock: (p: any) => Promise<any>;
   *    } | null;
   *    provider?: JsonRpcProvider;
   *    partnerPolicyObjectId?: string;
   * };
   */

  return (
    <>
      <UmiSwapWidget
        accountAddress={currentAccount?.address}
        wallet={currentWallet}
        provider={provider}
        partnerPolicyObjectId="0x1234....abcde"
      />
    </>
  );
}

export default App;

Hooks

Or you can use the hooks directly:

import { useBalance, useCoinList, useQuoteApi } from "@umi-ag/swap-widget";

const balances = useBalance({
  chain, // default to Sui
  provider: props.provider, // JsonRpcProvider
  accountAddress: props.accountAddress, // string
});

const coinList = useCoinList({
  chain,
});

const quote = useQuoteApi({
  chain,
  quoteQuery,
});

These hooks use swr internally, so you can access the data and error like this:

const { data: balances, error: balanceError } = useBalance({
  chain,
  provider: props.provider,
  accountAddress: props.accountAddress,
});

For the detail of QuoteQuery, please refer to Umi SDK

These hooks will handle fetching data from the quote and sui-coin-list APIs, respectively, and will return the data and any error that occurs during the fetch.
