Prerequisites

You need to have telegraf installed on your project to use that plugin.

See offical guide for more info. Once you have installed telegraf in your project, you can use telegraf-pagination.

Installing

Run one of these commands depending on what package manager you're using:

$ npm install telegraf-pagination

or

$ yarn add telegraf-pagination

Quick start

Default mode

const { Pagination } =  require('telegraf-pagination');

let data = [...]; // define data as an array

bot.start(async ctx => {
    let pagination = new Pagination({ data });
    let text = await pagination.text();
    let keyboard = await pagination.keyboard();
    ctx.reply(text, keyboard);

    pagination.handleActions(bot);
});

Lazy mode

const { Pagination } =  require('telegraf-pagination');

let data = [...]; // define data as an array

bot.start(async ctx => {
    let pagination = new Pagination({
        lazy: true, // switch lazy mode on
        data: (page, size) => data.slice((page-1)*size, page*size), // callback that returns items of the page. Can be asynchronous
        total: data.length // optional. can be useful when generating a header
    });
    let text = await pagination.text();
    let keyboard = await pagination.keyboard();
    ctx.reply(text, keyboard);

    pagination.handleActions(bot);
});

Full Example

const { Markup, Telegraf } = require("telegraf");
const { Pagination } = require("telegraf-pagination");

const TOKEN = "YOUR_BOT_TOKEN";
const bot = new Telegraf(TOKEN);

let fakeData = Array(10)
  .fill(0)
  .map((_, i) => ({
    id: i,
    title: `Item ${i + 1}`,
  }));

bot.command("pagination", async (ctx) => {
  const pagination = new Pagination({
    data: fakeData, // array of items
    header: (currentPage, pageSize, total) =>
      `${currentPage}-page of total ${total}`, // optional. Default value: 👇
    // `Items ${(currentPage - 1) * pageSize + 1 }-${currentPage * pageSize <= total ? currentPage * pageSize : total} of ${total}`;
    format: (item, index) => `${index + 1}. ${item.title}`, // optional. Default value: 👇
    // `${index + 1}. ${item}`;
    pageSize: 8, // optional. Default value: 10
    rowSize: 4, // optional. Default value: 5 (maximum 8)
    isButtonsMode: false, // optional. Default value: false. Allows you to display names on buttons (there is support for associative arrays)
    buttonModeOptions: {
      isSimpleArray: true, // optional. Default value: true. Enables/disables support for associative arrays
      titleKey: '' // optional. Default value: null. If the associative mode is enabled (isSimply: false), determines by which key the title for the button will be taken.
    },
    isEnabledDeleteButton: true, // optional. Default value: true
    onSelect: (item, index) => {
      ctx.reply(item.title);
    }, // optional. Default value: empty function
    messages: {
      // optional
      firstPage: "First page", // optional. Default value: "❗️ That's the first page"
      lastPage: "Last page", // optional. Default value: "❗️ That's the last page"
      prev: "◀️", // optional. Default value: "⬅️"
      next: "▶️", // optional. Default value: "➡️"
      delete: "🗑", // optional. Default value: "❌"
    },
    inlineCustomButtons: [
      Markup.button.callback('Title custom button', 'your_callback_name')
    ] // optional. Default value: null
  });

  pagination.handleActions(bot); // pass bot or scene instance as a parameter

  let text = await pagination.text(); // get pagination text
  let keyboard = await pagination.keyboard(); // get pagination keyboard
  ctx.replyWithHTML(text, keyboard);
});

bot.launch().then(() => {
  console.log("Bot is running");
});
