help pls

You have already set up express as a variable, and now can't change it because it's ALREADY a constant.

P.S: This is a sign you cant' understand the code you're writing. If you don't understand the code you are writing, then you NEED to go to the basics and learn JavaScript itself before delving into complicated topics like Node.js and APIs.

i'm good with that tho

Hey,
I made mine using Python and unfortunately it didn't work. I'm guessing it's because I can't see the token because it is in .env and Uptime Monitor is not the owner. I even tried it without the .env, it still didn't work can you help me?

Python isn't necessarily the language for back-end web apps. Either use Go or Node.js. Go is phenomenal for the job because it's incredibly fast, yet its size is bloated so not good for storage-sensitive applications. Luckily, servers aren't storage-sensitive which is where it's supposed to run :) On the other hand, Node.js is delightfully tiny, only as big as the text file you made to run it. The down side is that it's much slower than languages like Go.

Unfortunately, your using Python, that is the problem. This is meant for discord.js. I would recommend going to here: dev.to/harshitojha/host-a-discord-...

It is a python version of this

Explox • Dec 21 '20

I used Node.js for this and it works. The guy in the tutorial did the same thing. So I recommend you try to use Node.js and see how it goes

Aplha101 • Apr 15 '21

I used this method mine is working but where can I add more features to it?

AnmolS149 • Jul 13 '21

Well, there are two things you can do:

Learn a coding language like JavaScript or Python... or
use Scratch for Discord to make a bot and host it on RepL.it. You don't need any coding knowledge. You will need some basic knowledge of file and package management... Here's scratch for discord: scratch-for-discord.netlify.app

there can be some bugs with it, also you need to create a .env file to protect your bot token from hacking....

Cent • Aug 12 '20

Thanks for this! I've used Repl.it before but never for hosting purposes

Hassan-BH • Mar 29 '21

Yes of course.

Force Studios - Comms Open • Dec 23 '20

It's good, i'm pretty sure you're using "Atom" as a coding platform. Visual Code & Atom is same. Almost every coding software is the same and can be used on as long as you have discord.js downloaded by downloading node.js

Hi, I have a repl team and it not working when I put the URL in to uptime robot. (not keeping online)

Creations Studios • Jun 22 '21

Hi it won't work. The bot isn't online and in repl it said the token is invalid.

Opilite Elix • Oct 13 '22

same

Opilite Elix • Oct 13 '22

and the repl brakes and can't wake up

Arya Sarukkai • Jan 6 '21

With this, people can access the code and token of this bot though, right?

bestPlayerXu • Jan 11 '21

no. the .env file is the only private-hidden file.

AnmolS149 • Jul 13 '21

no the .env file is private and can be only viewed by you...plus what are the odds of someone searching your rep and then scrolling through it to find your token...also you can always regenerate it...

pAAAAp • Sep 24 '20

Would this work if you close the Uptime Robots tab?

Gio2chi • Apr 14 '21

It still works?

Hassan-BH • Mar 29 '21

I don't know how to thank you dude.
You rock!

duckyisgood • Aug 27 '20

can you do it on python?

Agil Triono • Oct 24 '21

i have been created one discord bot it is been in development but i have the fork version so to try this , it work !!
Used uptimerobot for every 30 minutes with delay 1 minutes .

BradTFT • Oct 14 '21

so when i paste my webserver url into uptime robot is just says "Enter a valid IP or FQDN" any fixes for this?

emily :) |open commisions| • Aug 26 '21

It doesn't work, what to do
also with the new secrets thing idk what
for the "Next we need to instantiate our bot." do we like put it in the same file?

Waren Gonzaga • Sep 9 '20

Is there any limits on users? What if you host a music discord bot in your repl it will buffer?

AnmolS149 • Jul 13 '21

I host 3 separate scripts (reps) for the same bot on RepL..they are a chat bot, a rank bot and a music bot...none of them lag...

PartyBoy Gaming • Jul 1 '21

I can’t find my web server link what do I do?
(Ps I dont have the web tab in the bottom)

Cyrah Aerin Cirineo • Apr 27 '21

so how do i add a prefix to the bot ?!

ive been trying to do it for awhile but it hasnt been working

avuleee • Apr 23 '21

You have to go to the Secret Enviroment and type in "DISCORD_TOKEN" as the key and your bot's token in value for .env.

VenomousSteam81 • Apr 21 '21

Hey, they made it so people cant make .env files anymore. You have to use Secrets (Environment Variables) tab on the side. Can you make an updated version?

VenomousSteam81 • Apr 21 '21

Nevermind. I figured out a solution!

CoderStarTrek • Jun 9 '20

Does this depend on your computer to be online at all times?

Fizal Sarif • Aug 19 '20

It does not! Your bot is hosted on replit's servers so you can close the chrome tab even you're done setting it up

Harrison • Nov 12 '20 • Edited

Guys this only works on Node.js(as far as i know) and if uptimerobot.com is not working then check the link or pause and start again.

Existable • Dec 9 '20

How do I make it so then I can add more commands instead of just the ping command?

Force Studios - Comms Open • Dec 23 '20

Get discord.js by downloading node.js
I would recommend this code if you want a 2nd answer from the person and bot:

client.on('message', msg => {
if (msg.content === 'PERSONS MESSAGE') {
msg.reply('BOTS REPLY');
} else if (msg.content === 'PERSONS MESSAGE') {
msg.reply('BOTS REPLY')
}
});

// This is the full message command
