TonConnect UI Vue

Introduction

TonConnect UI Vue is a library that provides components and context for integrating TonConnect UI in your Vue.js applications. This README will guide you through the setup and usage of the library.

Installation

To install the library, use your preferred package manager:

npm install ton-ui-vue @tonconnect/ui
# or
yarn add ton-ui-vue @tonconnect/ui

Setup

1. Import and Create the TonConnectUIProvider

In your main.ts, import the necessary functions and contexts from ton-ui-vue, and create the TonConnectUIProvider with your manifest URL.

import { createApp } from 'vue';
import App from './App.vue';
import {
    createTonConnectUIProvider,
    TonConnectUIContext,
    TonConnectUIOptionsContext
} from 'ton-ui-vue';

const { tonConnectUI, setOptions } = createTonConnectUIProvider({
    manifestUrl: 'https://gist.githubusercontent.com/siandreev/75f1a2ccf2f3b4e2771f6089aeb06d7f/raw/d4986344010ec7a2d1cc8a2a9baa57de37aaccb8/gistfile1.txt'
});

const app = createApp(App);

app.provide(TonConnectUIContext, tonConnectUI);
app.provide(TonConnectUIOptionsContext, setOptions);

app.mount('#app');

2. Using the Connect Button

To use the connect button in your components, follow these steps:

1. Import the TonConnectButton component in your script setup.
2. Use the TonConnectButton component in your template.

Example Component

Create a component or use the TonConnectButton in an existing component as shown below:

<script setup lang="ts">
import { TonConnectButton } from 'ton-ui-vue';
</script>

<template>
    <div>
        <TonConnectButton />
    </div>
</template>

3. Full Example

Below is a complete example combining the setup and usage of the connect button:

main.ts

import { createApp } from 'vue';
import App from './App.vue';
import {
    createTonConnectUIProvider,
    TonConnectUIContext,
    TonConnectUIOptionsContext
} from 'ton-ui-vue';

const { tonConnectUI, setOptions } = createTonConnectUIProvider({
    manifestUrl: 'https://gist.githubusercontent.com/siandreev/75f1a2ccf2f3b4e2771f6089aeb06d7f/raw/d4986344010ec7a2d1cc8a2a9baa57de37aaccb8/gistfile1.txt'
});

const app = createApp(App);

app.provide(TonConnectUIContext, tonConnectUI);
app.provide(TonConnectUIOptionsContext, setOptions);

app.mount('#app');

App.vue

<template>
    <div id="app">
        <TonConnectButton />
    </div>
</template>

<script setup lang="ts">
import { TonConnectButton } from 'ton-ui-vue';
</script>

4. Using useSendTransaction Composable

The useSendTransaction composable allows you to send transactions using the TonConnect UI in a flexible and dynamic way. You can add multiple transaction messages with specific addresses and amounts, manage the transaction state, and handle user actions.

Example Usage

<template>
  <div>
    <div v-for="(message, index) in messages" :key="index">
      <input v-model="message.address" placeholder="Enter address" />
      <input v-model="message.amount" placeholder="Enter amount" />
    </div>
    <button @click="addMessage('', '')">Add Message</button>
    <button @click="sendTransaction" :disabled="sending">
      Send Transaction
    </button>
    <p v-if="error">{{ error.message }}</p>
  </div>
</template>

<script setup lang="ts">
import { useSendTransaction } from '@/composables/useSendTransaction';

const { sendTransaction, sending, error, messages, addMessage, clearMessages } = useSendTransaction();

// Initialize with an empty message to start with
addMessage('0:b2a1ecf5545e076cd36ae516ea7ebdf32aea008caa2b84af9866becb208895ad', '100000000');
addMessage('0:a1b2c3d4e5f678901234567890abcdef1234567890abcdef1234567890abcdef', '200000000');
</script>

API

• sendTransaction(): Sends the transaction messages stored in the messages array.
• addMessage(address: string, amount: string): Adds a new transaction message to the messages array.
• clearMessages(): Clears all transaction messages from the messages array.
• messages: A reactive array containing the transaction messages.
• sending: A reactive boolean indicating if the transaction is currently being sent.
• error: A reactive error object that holds any errors encountered during the transaction process.

TonConnect UI Vue Integration for Nuxt 3

Step-by-Step Guide

Create a Plugin

Create a file named ton-with-vue.ts inside the plugins directory:

// plugins/ton-with-vue.ts
import {
  createTonConnectUIProvider,
  TonConnectUIContext,
  TonConnectUIOptionsContext,
  TonConnectButton,
} from "ton-ui-vue";

export default defineNuxtPlugin((nuxtApp) => {
  const { tonConnectUI, setOptions } = createTonConnectUIProvider({
    manifestUrl:
      "https://gist.githubusercontent.com/siandreev/75f1a2ccf2f3b4e2771f6089aeb06d7f/raw/d4986344010ec7a2d1cc8a2a9baa57de37aaccb8/gistfile1.txt",
  });

  nuxtApp.vueApp.component("TonConnectButton", TonConnectButton);
  nuxtApp.vueApp.provide(TonConnectUIContext, tonConnectUI);
  nuxtApp.vueApp.provide(TonConnectUIOptionsContext, setOptions);
});

This updated README now includes the documentation for the useSendTransaction composable, providing a clear example of how to use it alongside the existing TonConnect UI components and setup instructions.
