Permissions Guide for Bot Builders

Working with permissions in discord.js 14

Use the helpers discord.js exposes instead of juggling raw numbers. Everything below sticks to bigint so you avoid precision issues.

import { Client, GatewayIntentBits, PermissionsBitField } from 'discord.js';

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

const required = new PermissionsBitField([
  PermissionsBitField.Flags.ManageGuild,
  PermissionsBitField.Flags.ManageRoles,
]);

client.on('interactionCreate', async (interaction) => {
  if (!interaction.isChatInputCommand()) return;

  if (!interaction.memberPermissions?.has(required)) {
    return interaction.reply({
      content: 'You need Manage Guild + Manage Roles for this command.',
      ephemeral: true,
    });
  }

  // command logic...
});

await client.login(process.env.BOT_TOKEN);
