I was trying to add a command handler (or a command folder)

I haven't tried to add commands inside the folder, but everytime I try to run the code, it says:

"Cannot access 'client' before initialization"

I get the error itself, but I don't know what to do about it. It might refer to adding the code too early, but I have tried multiple times.

The Full index.js file is here:

const { REST, Routes, Collection } = require('discord.js');
const Token = process.env.TOKEN
const ClientID = process.env.CLIENT_ID
const fs = require('node:fs');
const path = require('node:path');

require('dotenv').config();
const dotenv = require('dotenv');

const commandsPath = path.join(__dirname, 'commands');
const commandFiles = fs.readdirSync(commandsPath).filter(file => file.endsWith('.js'));


for (const file of commandFiles) {
    const filePath = path.join(commandsPath, file);
    const command = require(filePath);
    // Set a new item in the Collection with the key as the command name and the value as the exported module
    if ('data' in command && 'execute' in command) {
        client.commands.set(command.data.name, command);
    } else {
        console.log(`[WARNING] The command at ${filePath} is missing a required "data" or "execute" property.`);
    }
}

client.commands = new Collection();


const commands = [
  {
    name: 'ping',
    description: 'Get the latency/ping of the bot.',
  },
];

const rest = new REST({ version: '10' }).setToken(process.env.TOKEN);

(async () => {
  try {

    console.log('Started refreshing application (/) commands.');

    await rest.put(Routes.applicationCommands(process.env.CLIENT_ID), { body: commands });

    console.log('Successfully reloaded application (/) commands.');
  } catch (error) {
    console.error(error);
  }
})();


const express = require("express");
const app = express()
const { Client, GatewayIntentBits } = require('discord.js');
const client = new Client({ intents: [GatewayIntentBits.Guilds] });

client.on('ready', () => {
  console.log(`Candy is running, Logged in as ${client.user.tag}!`);
  client.user.setPresence({
        status: "online",  //You can show online, idle....
        activity: {
            name: "Using slash commands",  //The message shown
            type: "LISTENING" //PLAYING: WATCHING: LISTENING: STREAMING:
        }
    });
});

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

  if (interaction.comsmandName === 'ping') {
    const ping = await interaction.reply({ content: 'Pinging...', fetchReply: true });
    interaction.editReply(`Roundtrip latency: ${ping.createdTimestamp - interaction.createdTimestamp}ms`);
  }
});

 
client.login(process.env.TOKEN);

I first tried to rearrange "client.commands = new Collection();" after the:

const commandsPath = path.join(__dirname, 'commands');
const commandFiles = fs.readdirSync(commandsPath).filter(file => file.endsWith('.js'));

It still had the same error, so I putted it more to the bottom, but it still didn't work.

So, I tried to move the commands folder inside the source/src folder. But it still printed out the error.

CodePudding user response：

"Cannot access 'client' before initialization"

The error tells that the client you are trying to access (in the first if block: initialize.js:25) should be initialised before in other words, move the lines along with the required imports before that if block:

//..

const { Client, GatewayIntentBits } = require('discord.js');
const express = require("express");

// ..

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

client.commands = new Collection();


//..rest of the code

Note: the code is omitted for brevity

Edit: To prevent this systematically, you might want to use
