@tronweb3/tronwallet-adapter-vue-hooks

@tronweb3/tronwallet-adapter-vue-hooks provides a useWallet() hook which will make it easy to "Connect Wallet" and listen to the state change for developers.

Installation

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

Whether automatically connect to current selected wallet after the page is loaded when autoConnect enabled. If you don't want to connect the wallet when page is first loaded, set disableAutoConnectOnLoad: true.

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>
```
