require('dotenv').config();
const { Client, GatewayIntentBits } = require('discord.js');
const axios = require('axios');

const client = new Client({ intents: [GatewayIntentBits.Guilds, GatewayIntentBits.GuildMessages, GatewayIntentBits.MessageContent] });

client.once('ready', () => {
  console.log(`Logged in as ${client.user.tag}!`);
});

client.on('messageCreate', async (message) => {
  if (message.author.bot) return;

  if (message.content.startsWith('!bard')) {
    const query = message.content.replace('!bard', '').trim();

    if (!query) {
      message.channel.send('Please provide a prompt for Bard.');
      return;
    }

    try {
      const response = await axios.post(
        'https://bard.googleapis.com/v1/creations:generate',
        { prompt: query },
        {
          headers: {
            'Authorization': `Bearer ${process.env.BARD_API_KEY}`,
            'Content-Type': 'application/json',
          },
        }
      );

      const bardResponse = response.data.response;
      message.channel.send(bardResponse);
    } catch (error) {
      console.error('Error fetching Bard response:', error);
      message.channel.send('Sorry, I could not fetch a response from Bard.');
    }
  }
});

client.login(process.env.DISCORD_TOKEN);
