I am working on a bot i made a roast command i am getting this error
internal/modules/cjs/loader.js:1089
throw new ERR_REQUIRE_ESM(filename, parentPath, packageJsonPath);
^
Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: C:\Users\acer\Documents\test\node_modules\node-fetch\src\index.js
require() of ES modules is not supported.
require() of C:\Users\acer\Documents\test\node_modules\node-fetch\src\index.js from C:\Users\acer\Documents\test\commands\roast.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from C:\Users\acer\Documents\test\node_modules\node-fetch\package.json.

this is my roast.js
const random = require("something-random-on-discord").Random
const oneLinerJoke = require('one-liner-joke');
const fetch = require('node-fetch')
const Discord = require('discord.js')
module.exports = {
name : 'roast',
description : 'roasts a user',
async execute(message, args){
if (!args[0]) return message.channel.send('Invalid Format')
const mentionedMember = message.guild.mentions.member.first();
if (!mentionedMember) return message.channel.send('User not found')
let msg = await message.channel.send('Setting a roast...')
fetch('http://evilinsult.com/generate_insult.php?lang=en&type=json')
.then(res => res.json())
.then(json => {
message.channel.send(json.insult)
});
}
}
this is my main.js
// Import the discord.js module
const Discord = require('discord.js');
const fs = require('fs');
// Create an instance of a Discord client
const client = new Discord.Client();
client.commands = new Discord.Collection();
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));
const prefix = "$"
/**
* The ready event is vital, it means that only _after_ this will your bot start reacting to information
* received from Discord
*/
client.on('ready', () => {
console.log('I am ready!');
});
client.on('message', message => {
if (!message.content.startsWith(prefix) || message.author.bot) return;
const args = message.content.slice(prefix.length).trim().split(/ +/);
const command = args.shift().toLowerCase();
if(command === 'pingg'){
client.commands.get('pingg').execute(message, args);
}
if(command === 'roast'){
client.commands.get('roast').execute(message, args);
}
if (!client.commands.has(command)) return;
try {
client.commands.get(command).execute(message, args);
} catch (error) {
console.error(error);
message.reply('there was an error trying to execute that command!');
}
});
commandFiles.forEach(file => {
const command = file.split(/.js$/)[0];
client.commands.set(command, require(`./commands/${file}`));
});
client.login('censored');
as the error states :
package.json contains "type": "module" which defines all .js files in that package scope as ES modules
you usually have 3 options:
in your particular case, you are using node-fetch which is now esmodule only (since version 3). then the only solution available for you is to use import everywhere.
requires should become something like this:
import {Random} from 'something-random-on-discord';
import oneLinerJoke from 'one-liner-joke';
import fetch from 'node-fetch';
import Discord from 'discord.js';
EDIT: you can also remove node fetch or revert to branch v2 to keep using require.
As mention in the README.md also...
Another way to make fetch@3 happen is to import node-fetch using the async import() supported in node v12.20
const fetch = (...args) => import('node-fetch').then(({default: fetch}) => fetch(...args));
this works from commonjs also (the next request won't re-import node-fetch cuz modules gets cached) This can make the Node process boot up faster and only lazy loads the node-fetch when it's needed
here is another way to preload it:
const fetchP = import('node-fetch').then(mod => mod.default)
const fetch = (...args) => fetchP.then(fn => fn(...args))
You don't necessary have to convert your hole project to ESM just b/c we did it. You can also stay with the v2 branch - we will keep updating v2 with bug/security issues. But not so much with new features...
( Still recommend others to switch to ESM doe )
For TypeScript users who are only after the Types, you can do:
import type { Request } from 'node-fetch' (this will not import or transpile anything - this typing annotation will just be discarded)
There is a hole section of how to import/require node fetch in cjs projects at #1279
