Documentation

• Documentation
• Migrating to v0.5.x and beyond

Installation

yarn add ethers vue-dapp

If you want to support more wallet providers not only MetaMask, you should install respective packages to enable the dynamic import.

• Support WalletConnect

yarn add @walletconnect/web3-provider

• Support Coinbase Wallet

yarn add @coinbase/wallet-sdk

• Support Gnosis Safe

yarn add @gnosis.pm/safe-apps-provider @gnosis.pm/safe-apps-sdk

Quick Start

Step 1. Add plugin to your app:

import { VueDapp } from "vue-dapp";
const app = createApp(App);
app.use(VueDapp);
app.mount("#app");

Step 2. By default, VueDapp includes Mainnet and Goerli networks, but you can extend it to include other networks:

app.use(VueDapp, {
 autoConnect: true, // Automatically connect MetaMask wallet when the page is loaded
  networks: {
    80001: {
      chainId: ethers.utils.hexValue(80001),
      blockExplorerUrls: ['https://mumbai.polygonscan.com/'],
      chainName: 'Mumbai',
      rpcUrls: ['https://rpc-mumbai.maticvigil.com/'],
      nativeCurrency: {
        name: 'Mumbai',
        decimals: 18,
        symbol: 'MATIC',
      },
    },
    42161: {
      ...
    },
  },
});

Step 3. Add <vd-board /> to your App.vue and add a button to open the board:

<button @click="open">Connect Wallet</button>
<vd-board :connectors="connectors" dark />

Step 4. Construct your connectors and use composable functions in your scripts:

import {
  MetaMaskConnector,
  WalletConnectConnector,
  CoinbaseWalletConnector,
  useBoard,
} from "vue-dapp";

setup() {
  const { open } = useBoard();
  const infuraId = "";
  const connectors = [
    new MetaMaskConnector({
      appUrl: "http://localhost:3000",
    }),
    new WalletConnectConnector({
      qrcode: true,
      rpc: {
        1: `https://mainnet.infura.io/v3/${infuraId}`,
        4: `https://rinkeby.infura.io/v3/${infuraId}`,
      },
    }),
    new CoinbaseWalletConnector({
      appName: "Vue Dapp",
      jsonRpcUrl: `https://mainnet.infura.io/v3/${infuraId}`,
    }),
  ];
  return {
    connectors,
    open,
  };
}
