Installation

First of all you need a telegram bot, if you don't know to how to create a telegram bot please check this link.

Step 1:

Install the module:

npx nuxi module add nuxt-telegram-auth

Step 2:

You need grab bot token from telegram, you can get your bot's token from Bot_Father:

Then add your nuxt.config.ts file:

runtimeConfig: {
  TELEGRAM_TOKEN: "my_fancy_bot_token",
}

also you need allow your domain on Bot_Father otherwise you will get "Invalid Domain" error.

After that you can use TelegramLoginWidget component:

<template>
  <div>
    <div>
      <div v-if="session.loggedIn">
        <NuxtLink @click="logout" to="/">Logout</NuxtLink>
        <a>Hey you are logged in!</a>
        <p>Session: {{ session }}</p>
      </div>
      <div v-else>
        <TelegramLoginWidget telegram-login="my_bot" @callback="testCallback" />
      </div>
    </div>
  </div>
</template>

<script setup>
const { clearSession, session } = useUserSession();
const logout = () => clearSession();
const testCallback = (user) => {
  console.log("Custom callback function: ",user);
};
</script>

telegram-login value should be your bot's name.

@callback emit is optional.
