index.js

client.on("ready", function (readyClient) {
    // Discord Player Initialization
	const { Player } = require("discord-player");
	const player = new Player(readyClient);
});
 
client.on("interactionCreate", async (interaction) => {
    if (interaction.isAutocomplete()) {
        // Handling autocomplete requests
        ...
        await command.autocompleteRun(interaction);
    } else if(interaction.isChatInputCommand()){
        // Handling chat slashCommand  requests
        ...
        await command.execute(interaction);
    }
});

play.js

import { useMainPlayer } from 'discord-player';
 
async function autocompleteRun(interaction) {
    const player = useMainPlayer();
    const query = interaction.options.getString('query', true);
    const results = await player.search(query);
 
    // Returns a list of songs with their title
    return interaction.respond(
        results.tracks.slice(0, 10).map((t) => ({
            name: t.title,
            value: t.url,
        })),
    );
}
 
async function execute(interaction) {
    const player = useMainPlayer();
    const query = interaction.options.getString('query');
    const searchResult = await player.search(query, { requestedBy: interaction.user });
 
    if (!searchResult.hasTracks()) {
        // Check if we found results for this query
        await interaction.reply(`We found no tracks for ${query}!`);
        return;
    } else {
        await player.play(interaction.member.voice.channel, searchResult, {
            nodeOptions: {
                metadata: interaction.channel,
                // You can add more options over here
            },
        });
    }
    await interaction.reply({ content: `Loading your track(s)"}` });
