# or pnpm install @tronweb3/tronwallet-adapter-vue-hooks @tronweb3/tronwallet-abstract-adapter @tronweb3/tronwallet-adapters

Usage

@tronweb3/tronwallet-adapter-vue-hooks uses Provide / Inject in Vue to maintain a shared data. So developers need to wrap App content within the WalletProvider.

You can provide a onError callback to handle various errors such as WalletConnectionError, WalletNotFoundError.

Here is a Demo project;

<script setup>
    import { defineComponent, h } from 'vue';
    import { WalletProvider, useWallet } from '@tronweb3/tronwallet-adapter-vue-hooks';
    import { TronLinkAdapter } from '@tronweb3/tronwallet-adapters';
    const tronLink = new TronLinkAdapter();

    const adapters = [tronLink];

    function onConnect(address) {
        console.log('[wallet hooks] onConnect: ', address);
    }
    function onDisconnect() {
        console.log('[wallet hooks] onDisconnect');
    }

    const VueComponent = defineComponent({
        setup() {
            // Here you can use `useWallet` API
            const { wallet, connect, signMessage, signTransaction } = useWallet();
            return () =>
                h('div', [
                    h('div', { style: 'color: #222;' }, `Current Adapter: ${(wallet && wallet.adapter.name) || ''}`),
                ]);
        },
    });
</script>

<template>
    <WalletProvider :adapters="adapters" @connect="onConnect" @disconnect="onDisconnect">
        <VueComponent />
    </WalletProvider>
</template>

`WalletProvider`

WalletProvider and useWallet work together. WalletProvider use provide() in Vue to provide a shared state. useWallet use inject() to get the shared state. Developers need to wrap application components with WalletProvider.

<html>
    <WalletProvider>/* here is application components */</WalletProvider>
</html>
<script setup>
    import { useWallet, WalletProvider } from '@tronweb3/tronwallet-adapter-vue-hooks';
</script>

Props

adapters:

Required: false
Type: Adapter[]
Default: [ new TronLinkAdapter() ]

Used to specify what wallet adapters are supported. All wallet adapters can be imported from @tronweb3/tronwallet-adapters package or their standalone package.

Example

<template>
    <WalletProvider :adapters="adapters">/* here is application components */</WalletProvider>
</template>
<script setup>
    import { useWallet, WalletProvider } from '@tronweb3/tronwallet-adapter-vue-hooks';
    import { TronLinkAdapter } from '@tronweb3/tronwallet-adapters';
    const adapters = [new TronLinkAdapter()];
</script>

autoConnect

Required: false
Type: boolean
Default: true

Whether connect to the specified wallet automatically after a wallet is selected.

disableAutoConnectOnLoad

Required: false
Type: boolean
Default: false

localStorageKey

Required: false
Type: string
Default: tronAdapterName

Specified the key used to cache wallet name in localStorage. When user select a wallet, applications will cache the wallet name to localStorage.

Events

You can provide event handlers for listen adapter events, such as connect,disconnect,accountsChanged. Available events and their types are as follows:

readyStateChanged: (readyState: 'Found' | 'NotFound') => void: Emits when current adapter emits readyStateChanged event.
connect: (address: string) => void: Emits when current adapter emits connect event.
disconnect: () => void: Emits when current adapter emits disconnect event.
accountsChanged: (newAddress: string; preAddress?: string) => void: Emits when current adapter emits accountsChanged event.
chainChanged: (chainData: unknow) => void: Emits when current adapter emits chainChanged event.
error: (error) => void: Emits when occurs error in methods calls.

An event named adapterChanged is also avaliable to get noticed when selected adapter is changed.

adapterChanged: (adapter: Adapter | undefined) => void: Called when current adapter is changed.

Here is an example:

```html
<template>
    <WalletProvider :adapters="adapters" @accountsChanged="onAccountsChanged">/* here is application components */</WalletProvider>
</template>
<script setup>
    import { useWallet, WalletProvider } from '@tronweb3/tronwallet-adapter-vue-hooks';
    import { TronLinkAdapter } from '@tronweb3/tronwallet-adapters';
    const adapters = [new TronLinkAdapter()];

    function onAccountsChanged(curAddress, preAddress) {}
</script>
```
