Configure Swap Widget with TonConnectUI

To integrate our Swap Widget into your application , follow these steps to configure and set up the widget using the @swap-coffee/ui-sdk and @tonconnect/ui.

​
1. Create a Configuration File

First, create a configuration file to manage your settings for TonConnect and the Swap Widget. This file will include the manifestUrl for the TonConnect manifest and other configuration parameters. Here’s an example configuration file named config.js: 
import { THEME } from "@tonconnect/ui";

// TonConnect manifest URL
const manifestUrl = "https://swap.coffee/tonconnect-manifest.json";

// TonConnect configuration
export const tonConnectConfig = {
    /**
     * The URL of the TonConnect manifest file.
     * This manifest provides details about the TonConnect application and its settings.
     * This URL should point to a JSON file located in the public folder of your project.
     *
     * @type {string}
     */
    manifestUrl: manifestUrl,

    /**
     * User interface preferences for TonConnect.
     * This allows customization of the appearance of the TonConnect UI.
     *
     * @type {Object}
     * @property {string} theme - The theme of the TonConnect UI. Values include 'DARK' and 'LIGHT'.
     */
    uiPreferences: {
        theme: THEME.DARK
    },
};

// Swap Widget configuration
export const swapWidgetConfig = {
    /**
     * Theme setting for the Swap Widget.
     * Determines the visual style of the widget.
     *
     * @type {string}
     */
    theme: 'dark',

    /**
     * The connection method used for integrating the Swap Widget.
     * Defines how the widget interacts with the wallet for transactions.
     *
     * Options:
     * - 'tonConnect' (most common): Uses TonConnect for seamless wallet integration.
     * - 'payload': A custom method that bypasses TonConnect and requires manual payload configuration for wallet interactions.
     *
     * @type {string}
     */
    injectionMode: 'tonConnect',

    /**
     * Locale setting for the Swap Widget.
     * Defines the language and regional settings for the widget.
     *
     * @type {string}
     */
    locale: 'en',

    /**
     * Configuration for TonConnect manifest in the Swap Widget.
     * This setting tells the widget where to find the TonConnect manifest.
     *
     * @type {Object}
     * @property {string} url - The URL of the TonConnect manifest.
     */
    tonConnectManifest: {
        url: manifestUrl
    }
};
This configuration file allows you to customize both the TonConnect UI and the Swap Widget. Make sure that the manifestUrl points to the correct location of the TonConnect manifest file in your public folder to ensure proper integration and functionality.

​
2. createSwapWidget properties (via TonConnect injection mode)

When using the TonConnect injection mode, the createSwapWidget function accepts several configuration properties that allow you to customize the widget’s appearance, behavior, and connection settings.

​
Container Selector (string):

  • The CSS selector for the HTML element where the Swap Widget will be rendered.
Example: '#swap-widget-component'

​
Configuration Object (object):

This object contains the settings to customize the Swap Widget:
  • theme (string): Defines the visual theme of the widget.
Options: 'light', 'dark', 'coffee'
  • locale (string): Specifies the language and regional settings for the widget.
Options: 'zh', 'ua', 'ru', 'en', 'es', 'fr', 'fa'
  • tonConnectManifest (object): Configuration for the TonConnect manifest.
    • url (string): The URL pointing to the TonConnect manifest. This manifest contains details about the TonConnect application and its settings.
  • tonConnectUi (TonConnectUI instance): An instance of TonConnectUI for managing wallet connections and interactions.

​
injectionMode (string):

  • Specifies the connection method to be used for wallet interactions.
Example: 'tonConnect'

​
3. createSwapWidget usage

import { createSwapWidget } from '@swap-coffee/ui-sdk';
import { TonConnectUI } from '@tonconnect/ui';
import { swapWidgetConfig } from './config'; // Configuration file

createSwapWidget('#swap-widget-component', {
    // Provide the container selector where the Swap Widget will be rendered
    ...swapWidgetConfig,  // Spread the existing Swap Widget configuration

    // Pass the initialized TonConnectUI instance for TonConnect integration
    tonConnectUi: tonConnectUiInstance,
});

​
Configure Swap Widget with Payload Injection

To integrate our Swap Widget into your application, follow these steps to configure and set up the widget using the @swap-coffee/ui-sdk with Payload Injection Mode.

​
1. Create a Configuration File

First, create a configuration file to manage your settings for the Swap Widget. This file will include the configuration parameters required for the Payload connection method. Here’s an example configuration file named config.js: 
// Swap Widget configuration
export const swapWidgetConfig = {
    /**
     * Theme setting for the Swap Widget.
     * Determines the visual style of the widget.
     *
     * @type {string}
     */
    theme: 'dark',

    /**
     * The connection method used for integrating the Swap Widget.
     * Defines how the widget interacts with the wallet for transactions.
     *
     * Options:
     * - 'tonConnect' (most common): Uses TonConnect for seamless wallet integration.
     * - 'payload': A custom method that bypasses TonConnect and requires manual payload configuration for wallet interactions.
     *
     * @type {string}
     */
    injectionMode: 'payload',

    /**
     * Locale setting for the Swap Widget.
     * Defines the language and regional settings for the widget.
     *
     * @type {string}
     */
    locale: 'en',
};
This configuration file allows you to customize the Payload Injection Mode for the Swap Widget. The injectionMode parameter is set to 'payload', indicating that the widget will bypass TonConnect and use a custom method for handling wallet interactions.

​
2. Payload Connection Configuration Structure for Swap Widget

To configure the Payload connection for the swap.coffee widget, you need to define the payload object. This object contains all necessary parameters for establishing a manual wallet connection.
Here is an example configuration (payload.js): 
export const payloadConnectionExampleConfig = {
     /**
     * The wallet's metadata that is used to authenticate the wallet connection.
     * This includes the wallet address and the relevant signatures for secure communication.
     *
     * @type {object}
     */
    wallet_meta: {
        /**
         * The address of the wallet, which is used for identifying the wallet in the transaction.
         *
         * @type {string}
         * @example "0:e82b785a9f11c271ce0418a921aa3fa255a98f6cff88be610b8ce2df66ed3ba6"
         */
        address: "0:e82b785a9f11c271ce0418a921aa3fa255a98f6cff88be610b8ce2df66ed3ba6",
    },

    /**
     * The verification data required for confirming the wallet connection.
     * This object contains the public key and the wallet's state initialization data,
     * along with a proof signature to ensure secure communication.
     *
     * @type {object}
     */
    verify: {
        /**
         * The public key of the wallet. This is used to authenticate the wallet in the connection process.
         *
         * @type {string}
         * @example "a4e1e6811b634985c82132c636fc7fbfef831bbfcf1593dc35f8291fe2c4af2c"
         */
        public_key: "a4e1e6811b634985c82132c636fc7fbfef831bbfcf1593dc35f8291fe2c4af2c",
