Unexpected token exception being thrown by firebase-admin library

I am using the firebase-admin library in my node application.
My index.js is empty, with the exception of the require statement for firebase-admin...
var admin = require('firebase-admin');
The exception being thrown from the require statement occurs at following line in firebase-admin/lib/default-namespace.js
const firebase_namespace_1 = require("./app/firebase-namespace");
The exception message is as follows...
Exception has occurred: SyntaxError: Unexpected token ?

Replacing main.js with index.js, Error: ENOENT?

I'm confused with why is this bot now functioning, I think it's as I don't have a "index.js" I use "main.js" How can I some how switch from "main.js" to "index.js"?
I'll add all the main codes that may help you spot an error :D
Here is the code in "main.js":
const { Client, Collection, Intents } = require('discord.js');
const client = new Client({ disableMentions: 'everyone', partials:
['MESSAGE', 'CHANNEL', 'REACTION'], ws: { intents: Intents.ALL } });
client.commands = new Collection();
client.aliases = new Collection();
['command', 'event'].forEach(handler => {
require(`./handlers/${handler}`)(client);
});
client.login(process.env.BOT_TOKEN);

As below link said you can Create a .replit file, and inside it put
run="node [file].js"
and replace [file] to main.
https://replit.com/talk/ask/Is-it-possible-to-changedeleted-indexjs/43264

Change the name file from main.js to index.js in "scripts" => "start" in package.json file and hit npm start. Remember to run the script from the folder where the main.js file is located, and rename files!

How to set up the preact-render-to-string on the express

Please tell me how to set up the preact-render-to-string on the express.
https://github.com/preactjs/preact-render-to-string#render-jsx--preact--whatever-via-express
https://expressjs.com/en/starter/installing.html
I built it reading the above links. The source code is on there, but I'm not used to node
I don't know how to execute it(Or I don't know if I'm failing to build the environment.).
I believe my installation procedure can be found in package.json(dependencies and devDependencies). So, below is my package.json.
My package.json:
{
"name": "y",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC",
"dependencies": {
"express": "^4.17.1"
},
"devDependencies": {
"preact": "^10.5.14",
"preact-render-to-string": "^5.1.19"
}
}
My app.js (Same as Document):
I didn't know what to do with the file name, so I used app.js.
import express from 'express';
import { h } from 'preact';
import render from 'preact-render-to-string';
/** #jsx h */
// silly example component:
const Fox = ({ name }) => (
<div class="fox">
<h5>{ name }</h5>
<p>This page is all about {name}.</p>
</div>
);
// basic HTTP server via express:
const app = express();
app.listen(8080);
// on each request, render and return a component:
app.get('/:fox', (req, res) => {
let html = render(<Fox name={req.params.fox} />);
// send it back wrapped up as an HTML5 document:
res.send(`<!DOCTYPE html><html><body>${html}</body></html>`);
});
Run and Error:
$ node app.js
src/pr/ex/app.js:1
import express from 'express';

I think I am running it wrong or failed to build the environment, what can I do to make it run successfully?
node is installed with nodebrew. The current status is as follows.
$ nodebrew list
v16.6.2
current: v16.6.2
Edit:
I tried the answer.
add the top-level "type" field with a value of "module"
The error SyntaxError: Cannot use import statement outside a module is gone and different error occurred.
$ node app.js
file:///src/pr/ex/app.js:8
<div class="fox">

SyntaxError: Unexpected token '<'
at Loader.moduleStrategy (node:internal/modules/esm/translators:146:18)
at async link (node:internal/modules/esm/module_job:67:21)
Since I am using preact (I must be using htm internally), it is odd that Unexpected token '<' would be an error.
package.json after editing:
{
"name": "y",
"version": "1.0.0",
"type": "module",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC",
"dependencies": {
"express": "^4.17.1"
},
"devDependencies": {
"preact": "^10.5.14",
"preact-render-to-string": "^5.1.19"
}
}

Possible solutions:
Use require:
const express = require('express')
const { h } = require('preact')
Save your app.js file as a .mjs file (Node13+ only)
Add { type: 'module' } in your package.json

Jest js node_modules\jest\node_modules\jest-cli\build\cli\index.js:227 } catch {

I run npm init npm i -D jest like in this tutorial
I am getting this error after running commend nmp test
This is not an error from creatures.js or creatures.test.js because without this file error happening. How can I fix this ? I tried already reinstating mode_modules. I don't know it have a matter but I'm using node 8.17.0 because I'm working with Firebase cloud functions

Upgrade node.js
In old version of node they were not handled the catch block of jest file.
It will work from node -v9.11.2 to so on.

You have to use socket.io-client for client side stuff. I have a hunch that charset.js uses a binary, or something that can't be converted to the browser.
https://github.com/socketio/socket.io-client

I was facing same problem but with some other module I did reinstall with latest and it is working for me
Problem
Error: Cannot find module './charset.js'
1) If you want to compile the package/file into executable, please pay attention to compilation warnings and specify a literal in 'require' call. 2) If you don't want to compile the package/file into executable and want to 'require' it from filesystem (likely plugin), specify an absolute path in 'require' call using process.cwd() or process.execPath.
