Example

function initializeTelesunBot() {
  // Initialize your bot with the provided token.
  const telesun = new Telesun.connectBot("<your-bot-token>");

  // Default handler for any incoming messages.
  telesun.use((ctx) => ctx.reply("Welcome to our service!"));

  // Handler for the `/start` command.
  telesun.start((ctx) => {
    ctx.reply("Welcome! Ready to explore?");
  });

  // Specific handler for text messages containing "hello".
  telesun.hears("hello", (ctx) =>
    ctx.reply("Hello there! How can I assist you today?")
  );

  // Handler for incoming photos.
  telesun.photo((ctx) => ctx.replyWithPhoto({ photo: "<photo-url|photo-id>" }));

  // Inline query handler.
  telesun.on("inline_query", (ctx) => {
    ctx.answerInlineQuery({
      results: [], // Specify the results array
      inline_query_id: ctx.inlineQuery.id, // Correctly reference inline_query_id
    });
  });
}

function demonstrateAdvancedFeatures() {
  // Advanced setup with spreadsheet connection and memory services.
  const telesun = new Telesun.connectBot("<your-bot-token>")
    .connectToSpreadSheet("<your-spreadsheet-id>")
    .temporaryMemory(CacheService)
    .permanentMemory(PropertiesService);

  telesun.on("message", (ctx) => {
    // Handling message updates.
    const update = ctx.update.message; // Correct method to access the message update.

    // Clearing a specified sheet.
    ctx.sheet("Sheet1").clear();

    // Preparing for the next interaction stage.
    ctx.setStage("message");

    // Sending an email notification.
    ctx.sendEmail(
      "email@example.com", // Use a placeholder or generic email for examples.
      "Telesun V2-beta Released",
      "We're excited to announce the release of Telesun V2-beta. Join us in enhancing and refining the documentation."
    );

    // Setting a temporary session value (with a default lifespan of 10 minutes).
    ctx.setTSessionValue("key", "value");
  });
}

Getting started

💊 Telegram token

To use the Telegram Bot API, you first have to get a bot account by chatting with BotFather.

BotFather will give you a token, something like 123456789:AbCdfGhIJKlmNoQQRsTUVwxyZ.

🚀 Launch Your First Gif Inline Query Bot

Welcome to this exciting tutorial where we'll embark on the journey of creating a Gif Inline Query bot. This isn't just any bot; it's your gateway to integrating the dynamic and fun world of GIFs right into any chat. Picture this: users type, scroll, and BAM! - an endless stream of GIFs at their fingertips. And guess what? We're tapping into the vast universe of GIPHY API to power our search for those perfect GIFs.

Features to Get Excited About:

• Instant Gratification: Just by mentioning the bot's username in the text area, you'll unleash a world of trending GIFs, loading automatically to greet the user.
• Search on the Fly: As users start typing their queries, our bot springs into action, fetching GIFs that match their search terms in real time.
• Infinite Scrolling Magic: As users delve deeper, scrolling through the GIFs, more and more GIFs magically appear, ensuring the fun never ends.

💪 Ready to dive in? I sure am. Let's get this show on the road and create a bot that brings smiles, laughs, and a whole lot of GIFs to any conversation.

Setup Guide

Get Started

• Create an App Script Project: Watch Tutorial
• Import Telesun Libraries: Learn How
• Craft Your Bot: Begin Here

Activate Inline Queries with Bot Father

1. Type /mybots to Bot Father.
2. Choose your bot.
3. Navigate to Bot Settings > Inline Mode.
4. Enable it.

Step 1: create your first function

create a function, name it anything you like, but for production purposes, the function name must be doPost.

function doPost() {
  // Bot initialization with your token.
  const telesun = new Telesun.connectBot("<your-bot-token>");

  // handles inline_query updates.
  telesun
    .on("inline_query", (ctx) => {
      // Your code here.
    })
    .longPolling(); // Maintains open connection for new updates.
}

Step 2: Integrate GIPHY API

Now, let's secure our API key from GIPHY API to access trending and search endpoints. Below is how we fetch GIFs:

// Fetch GIFs from Giphy, tailored by your query.
function fetchGifs(
  apiKey,
  query,
  offset = 0,
  limit = 20,
  rating = "g",
  lang = "en"
) {
  let baseUrl = "https://api.giphy.com/v1/gifs"; // Base endpoint.
  const queryParams = `api_key=${apiKey}&limit=${limit}&offset=${offset}&rating=${rating}&lang=${lang}`;

  // Adjust endpoint based on query presence.
  baseUrl += query
    ? `/search?q=${encodeURIComponent(query)}&${queryParams}`
    : `/trending?${queryParams}`;

  const response = UrlFetchApp.fetch(baseUrl); // Fetch the data.
  const json = JSON.parse(response.getContentText()); // Parse the JSON.
  return json.data; // Return the GIFs.
}

Step 3: Sending Inline Query Results

To respond to inline queries, our bot employs the answerInlineQuery method. This essential method requires parameters such as an array of results and the inline_query_id.

Each result object must include crucial details like type, id, gif_url, and thumbnail_url.

// Function to format GIFs for Telegram inline query response
function formatGifsForInlineQuery(gifs) {
  return gifs.map((gif) => ({
    type: "gif",
    id: gif.id,
    gif_url: gif.images.fixed_height.url,
    thumbnail_url: gif.images.fixed_height_small_still.url,
  }));
}

Step 4: Answering the Inline Query

function doPost() {
  // Initialize the bot with your token.
  const telesun = new Telesun.connectBot("<your-bot-token>");

  // Handle inline_query updates.
  telesun
    .on("inline_query", (ctx) => {
      const inline_query = ctx.inlineQueryUpdate();
      const query = inline_query.query;
      const offset = parseInt(inline_query.offset, 10) || 0; // Parse the offset, defaulting to 0 if absent.
      const apiKey = "<your-giphy-api-key>";
      const limit = 20; // Determine the number of results to fetch.

      // Fetch GIFs based on the user's query and the current offset.
      const gifs = fetchGifs(apiKey, query, offset, limit);
      const results = formatGifsForInlineQuery(gifs);

      // Reply to the inline query with the fetched results and set the next offset.
      const nextOffset = offset + limit;

      ctx.answerInlineQuery({
        results,
        inline_query_id: inline_query.id,
        next_offset: nextOffset.toString(),
      });
    })
    .longPolling(); // Maintain the connection for incoming updates.
}

Step 5: Making Our Code Production-Ready

Integrate the parameter e into both doPost(e) and handleWebhook(e) to elevate our code for production.

function doPost(e) {
  // Initialize the bot with your token.
  const telesun = new Telesun.connectBot("<your-bot-token>");

  // Handle inline_query updates.
  telesun
    .on("inline_query", (ctx) => {
      const inline_query = ctx.inlineQueryUpdate();
      const query = inline_query.query;
      const offset = parseInt(inline_query.offset, 10) || 0; // Parse the offset, defaulting to 0 if absent.
      const apiKey = "<your-giphy-api-key>";
      const limit = 20; // Determine the number of results to fetch.

      // Fetch GIFs based on the user's query and the current offset.
      const gifs = fetchGifs(apiKey, query, offset, limit);
      const results = formatGifsForInlineQuery(gifs);

      // Reply to the inline query with the fetched results and set the next offset.
      const nextOffset = offset + limit;

      ctx.answerInlineQuery({
        results,
        inline_query_id: inline_query.id,
        next_offset: nextOffset.toString(),
      });
    })
    .handleWebhook(e);
}

Our GIF inline query bot is now primed for launch. The upcoming section will guide you through deploying your project to the world.

📡 Deploying Your Gif Inline Query Bot

Ready to bring your bot to life? Just follow these simple steps:

• Ensure your primary script is named code.gs.
• Verify that doPost(e) is set as your main function.

Next, deploy your code to obtain the Web App URL. Not sure how? Watch this quick guide:

After deploying your code and securing your Web App URL, execute the following:

function SetWebhook() {
  new Telesun.connectBot("<your-bot-token>").setWebhook({
    url: "<your-web-app-url>",
  });
}

🌠 That's it! Dive in and enjoy interacting with your bot. 🎉
