TON Connect UI Vue

TonConnect UI Vue is a Vue UI kit for TonConnect SDK. Use it to connect your app to TON wallets via TonConnect protocol in Vue apps.

If you don't use Vue for your app, take a look at TonConnect UI and TonConnect UI React.

If you want to use TonConnect on the server side, you should use the TonConnect SDK.

You can find more details and the protocol specification in the docs.

Usage

Add TonConnectUIProvider

Add TonConnectUIProvider to the root of the app. You can specify UI options using props. // todo

All TonConnect UI hooks calls and <TonConnectButton /> component must be placed inside <TonConnectUIProvider>.

<template>
  <TonConnectUIProvider :options="options">
    <!-- Your app -->
  </TonConnectUIProvider>
</template>

<script>
import { TonConnectUIProvider } from '@townsquarelabs/ui-vue';

export default {
  components: {
    TonConnectUIProvider
  },
  setup(){
    const options = {
      manifestUrl:"https://<YOUR_APP_URL>/tonconnect-manifest.json",
    };
    return {
      options
    }
  }
}
</script>

Add TonConnect Button

TonConnect Button is universal UI component for initializing connection. After wallet is connected it transforms to a wallet menu. It is recommended to place it in the top right corner of your app.

<template>
  <header>
    <span>My App with Vue UI</span>
    <TonConnectButton/>
  </header>
</template>

<script>
import { TonConnectButton } from '@townsquarelabs/ui-vue';

export default {
  components: {
    TonConnectButton
  }
}
</script>

You can add class and :style props to the button as well. Note that you cannot pass child to the TonConnectButton. <TonConnectButton class="my-button-class" :style="{ float: 'right' }"/>

Use TonConnect UI hooks

useTonAddress

Use it to get user's current ton wallet address. Pass boolean parameter isUserFriendly to choose format of the address. If wallet is not connected hook will return empty string.

<template>
  <div v-if="address">
    <span>User-friendly address: {{ userFriendlyAddress }}</span>
    <span>Raw address: {{ rawAddress }}</span>
  </div>
</template>

<script>
import { useTonAddress } from '@townsquarelabs/ui-vue';

export default {
  setup() {
    const userFriendlyAddress = useTonAddress();
    const rawAddress = useTonAddress(false);

    return {
      userFriendlyAddress,
      rawAddress
    }
  }
}
</script>

useTonWallet

Use it to get user's current ton wallet. If wallet is not connected hook will return null.

See all wallet's properties // todo

<template>
  <div v-if="wallet">
    <span>Connected wallet: {{ wallet.name }}</span>
    <span>Device: {{ wallet.device.appName }}</span>
  </div>
</template>

<script>
import { useTonWallet } from '@townsquarelabs/ui-vue';

export default {
  setup() {
    const wallet = useTonWallet();

    return {
      wallet
    }
  }

}
</script>

useTonConnectModal

Use this hook to access the functions for opening and closing the modal window. The hook returns an object with the current modal state and methods to open and close the modal.

<template>
  <div>
    <div>Modal state: {{ state?.status }}</div>
    <button @click="open">Open modal</button>
    <button @click="close">Close modal</button>
  </div>
</template>

<script>
import { useTonConnectModal } from '@townsquarelabs/ui-vue';

export default {
  setup() {
    const { state, open, close } = useTonConnectModal();
    return { state, open, close };
  }
};
</script>

useTonConnectUI

Use it to get access to the TonConnectUI instance and UI options updating function.

    <div>

export default {
  name: 'Settings',
  setup() {
    const [tonConnectUI, setOptions] = useTonConnectUI();

    const onLanguageChange = (lang) => {
      setOptions({ language: lang as Locales });
    };

    const myTransaction = {
      validUntil: Math.floor(Date.now() / 1000) + 60, // 60 sec
      messages: [
        {
          address: "EQBBJBB3HagsujBqVfqeDUPJ0kXjgTPLWPFFffuNXNiJL0aA",
          amount: "20000000",
          // stateInit: "base64bocblahblahblah==" // just for instance. Replace with your transaction initState or remove
        },
        {
          address: "EQDmnxDMhId6v1Ofg_h5KR5coWlFG6e86Ro3pc7Tq4CA0-Jn",
          amount: "60000000",
          // payload: "base64bocblahblahblah==" // just for instance. Replace with your transaction payload or remove
        }
      ]
    }

    const sendTransaction = () => {
      tonConnectUI.sendTransaction(myTransaction);
    };

    return { onLanguageChange, sendTransaction };
  }
};
</script>

useIsConnectionRestored

Indicates current status of the connection restoring process. You can use it to detect when connection restoring process if finished.

<template>
  <div>
    <div v-if="!connectionRestored">Please wait...</div>
    <MainPage v-else />
  </div>
</template>

<script>
import { useIsConnectionRestored } from '@townsquarelabs/ui-vue';

export default {
  name: 'EntrypointPage',
  setup() {
    const connectionRestored = useIsConnectionRestored();
    return { connectionRestored };
  }
};
</script>

Add connect request parameters (ton_proof)

Use tonConnectUI.setConnectRequestParameters function to pass your connect request parameters.

This function takes one parameter:

Set state to 'loading' while you are waiting for the response from your backend. If user opens connect wallet modal at this moment, he will see a loader.

import { ref } from 'vue';
import { useTonConnectUI } from '@townsquarelabs/ui-vue';

const tonConnectUI = useTonConnectUI();

tonConnectUI.setConnectRequestParameters({
    state: 'loading'
});

or

Set state to 'ready' and define tonProof value. Passed parameter will be applied to the connect request (QR and universal link).

import { ref } from 'vue';
import { useTonConnectUI } from '@townsquarelabs/ui-vue';

const tonConnectUI = useTonConnectUI();

tonConnectUI.setConnectRequestParameters({
    state: 'ready',
    value: {
        tonProof: '<your-proof-payload>'
    }
});

or

Remove loader if it was enabled via state: 'loading' (e.g. you received an error instead of a response from your backend). Connect request will be created without any additional parameters.

import { ref } from 'vue';
import { useTonConnectUI } from '@townsquarelabs/ui-vue';

const tonConnectUI = useTonConnectUI();

tonConnectUI.setConnectRequestParameters(null);

You can call tonConnectUI.setConnectRequestParameters multiple times if your tonProof payload has bounded lifetime (e.g. you can refresh connect request parameters every 10 minutes).

import { ref } from 'vue';
import { useTonConnectUI } from '@townsquarelabs/ui-vue';

const tonConnectUI = useTonConnectUI();

// enable ui loader
tonConnectUI.setConnectRequestParameters({ state: 'loading' });

// fetch you tonProofPayload from the backend
const tonProofPayload: string | null = await fetchTonProofPayloadFromBackend();

if (!tonProofPayload) {
    // remove loader, connect request will be without any additional parameters
    tonConnectUI.setConnectRequestParameters(null);
} else {
    // add tonProof to the connect request
    tonConnectUI.setConnectRequestParameters({
        state: "ready",
        value: { tonProof: tonProofPayload }
    });
}

You can find ton_proof result in the wallet object when wallet will be connected:

import { ref, onMounted } from 'vue';
import { useTonConnectUI } from '@townsquarelabs/ui-vue';

const tonConnectUI = useTonConnectUI();

onMounted(() =>
    tonConnectUI.onStatusChange(wallet => {
        if (wallet.connectItems?.tonProof && 'proof' in wallet.connectItems.tonProof) {
            checkProofInYourBackend(wallet.connectItems.tonProof.proof, wallet.account);
        }
}));

Troubleshooting

Animations not working

If you are experiencing issues with animations not working in your environment, it might be due to a lack of support for the Web Animations API. To resolve this issue, you can use the web-animations-js polyfill.

Using npm

To install the polyfill, run the following command:

npm install web-animations-js

Then, import the polyfill in your project:

import 'web-animations-js';

Using CDN

Alternatively, you can include the polyfill via CDN by adding the following script tag to your HTML:

<script src="https://www.unpkg.com/web-animations-js@latest/web-animations.min.js"></script>

Both methods will provide a fallback implementation of the Web Animations API and should resolve the animation issues you are facing.
