N/A

i can see the link up

and i even tried to change the route in my frontend

heres an example : ```const form = document.getElementById('loginForm');
const emailInput = document.getElementById('email');
const passwordInput = document.getElementById('password');

form.addEventListener('submit', async (e) => {
e.preventDefault();

const email = emailInput.value.trim();
const password = passwordInput.value.trim();

if (!email || !password) {
alert('Por favor preenche os campos em branco');
return;
}

const data = { email, password };

try {
const response = await fetch('https://zethirahd-production-c2af.up.railway.app/api/auth/login', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify(data)
});

const result = await response.json();

if (response.ok && result.token) {
  alert('Login feito com sucesso!');

  localStorage.setItem('token', result.token);

  window.location.href = '/home.html';
} else {
  alert(result.message || 'Erro no sistema!');
}

} catch (error) {
alert('Um erro ocorreu, tente novamente mais tarde');
console.error('Login error:', error);
}
});
```

any logs on the api?

I just tested a POST request to that address through my http client and it returned 404

you mean in the backend ?

i see this logs on railway : MongoDB connection error: MongooseError: The uri parameter to openUri() must be a string, got "undefined". Make sure the first parameter to mongoose.connect() or mongoose.createConnection() is a string.

Error: ENOENT: no such file or directory, stat '/ZethiraHD/home.html'

the error is happening in your mongodb connection in your api

your api is prob crashing before even serving routes

so the problem is with my database ?

yes, did u also deploy a database in railway?

i did ,used mongodb

nice, and how did u point your API to use that db?

if u used the private url from the DB railway would show a connection arrow between your API ---> MongoDB on the dashboard

but the error says it received a undefined URI

i used a .env file to store the connections off my Mongodb databse….

did u manage to make it work @Richard Pinewood ?

Not yet, i am going to see if i can solve the problem tomorrow!

ok

it crashed 😭

can anyone just guide me in simple terms ?

medim can't read minds yet, you need to tell him the specific errors

i was able to setup it once,with a old project in the free tier

now this project has more things

^

for now it is appearing this : Mongo URI from .env: undefined

MONGO_URI is not defined. Check the .env file.

in the logs

i have installed dotenv

please do not use .env in a production environment

```require("dotenv").config({ path: "./.env" });

const express = require("express");
const mongoose = require("mongoose");
const cors = require("cors");
const path = require("path");
const authRoutes = require("./routes/userRoutes");

const app = express();
const PORT = process.env.PORT || 5000;
const MONGOURI = process.env.MONGOURI;

console.log("Mongo URI from .env:", MONGO_URI);

if (!MONGOURI) { console.error(" MONGOURI is not defined. Check the .env file.");
process.exit(1);
}

app.use(cors());
app.use(express.json());

mongoose
.connect(MONGO_URI)
.then(() => console.log("Connected to MongoDB"))
.catch((err) => console.error("MongoDB connection error:", err));

app.use("/uploads", express.static(path.join(dirname, "uploads"))); app.use(express.static(path.join(dirname, "../frontend/build")));

app.use("/api/auth", authRoutes);

app.get("/", (req, res) => {
res.sendFile(path.resolve(__dirname, "../ZethiraHD/home.html"));
});

app.listen(PORT, () => console.log(Server running on port ${PORT})); ```

but I'll let medim take it from here

why is it wrong ?

.env is for local development only

i hided the file from github

shouldnt be bcs of this ?

or railway will crash bcs of it ?

railway has nothing to do with .env files

but thats were i store the mongodb_url

^

this is my repo just in case if anyone is intrested to understand the project : https://github.com/RichardPinewood/ZethiraHD

ok you don't seem to be commiting your .envwhich is good

but did you set the service variables in railway?

no .env file, but there are multiple node_modules folders 😦

ye

@Richard Pinewood are you setting the service variables? also gitignore your node_modules

i didnt add any variables yet

in my backend

@Medim

what variable should i add ? the Mongo_URL ?

that's the issue

in your backend you use the MONGO_URI var

so you need to set it in the service variables

MONGO_URI=YOUR-MONGODB-URL

which you can use the reference variables from railway

the ones displayed here

so, the field VARIABLE_NAME would be MONGO_URI and the VALUE would be the reference to the mongodb url

could u try that @Richard Pinewood ?

But do i need to put the real credentials?

Like i did in the enviormental file?

yes

but in this case, you can use the reference variable just like I showed here

I mean, it needs to be the "real credential" otherwise how would it work? <:thonk:969365165688635464>

and by "real credential" I mean the mongodb one that is hosted on railway

could u try that @Richard Pinewood ?

exactly.

just one issue

in your code you use MONGO_URI (with an i)

you wrote MONGO_URL (with a l)

just the variable name

the value is correct

oh damn,i didnt noted that lmao

lets see

it still appears the same issue

^

^

^

wait,in the beggining should it be URI to ?

were it is these {}

it needs to be exactly as this screenshot

hmmmm

the first field should be MONGO_URI

i will delet the variable and do it again

yours is MONGO_URL

the second one you shouldn't change, since it's a reference variable

that works.

what if i change in the code ?

to URL ?

then u would change the service variable name to MONGO_URL too.

to match what your code uses.

do i need to add the "i" in the end ?

i wrote this : ${{MongoDB.MONGO_URI}}

yoo,the error dissapeared,now it is giving me a diffrent one funny

```MongoDB connection error: MongoParseError: Invalid scheme, expected connection string to start with "mongodb://" or "mongodb+srv://"

let me see if i can fix this first

that is wrong

that var shouldn't be changed, that var is provided by the MongoDB database you deployed, I think you're confusing things up a bit.

but seems like you app finally recognized the env var

just the value of it is wrong, since you changed it

i added the i later on before i checkmark the variable

what does your var looks like right now?

it looks like this

why is there an "i" at the end

you SHOULDN'T change the value field

isnt this an i ?

.

so i dont need to put an i at the end of the value ?

No, and you should never do that

i mean you forgot remove it in your example lol

it should be ${{MongoDB.MONGO_URL}}

I didn't put it in my example

but URL in my case is URI

I put it in the name

that doesn't matter.

just put it that way

and it should work flawlessly

just as I said in the first example I gave you

omg i feel so dumb ahaha

but have a look

now no red errors are appearing in the logs yeiii

i think the back is working fine !

now lets setup the frontend !

i will use netlify for that

congrats, you made it work

remember to also set the rest of your vars

and also remember this help thread isn’t for coding help, this wasn’t a railway related issue.

railway docs also introduce you on how it works so you should also take a look at it

the other variables like how many ?

?

that’s defined by you

did you use any other var in your project? any other process.env.var-here?

what did you have in your .env?

everything there can be a service var

no,i just have a .evn file in the backend

and in that enviromental i just stored the MONGO_URI,and the port

cool, so seems like you’re set.

for the frontend part,i just need to call the link they provide us right ?

you will generate a domain in the backend service settings

and call that domain in your frontend

damnn,its workingg !

i dont even need to use my machine to run my web-apps !

cool! so can Brody close this thread now?

i mean,yheaa

its working fine now !
