unique:true does stop from adding to database, but only getting the catch(e) error message. Tried using the findOne method, but as a beginner, architecture keeps messing me up.
require('dotenv').config()
const express = require('express')
const cors = require('cors')
const bodyParser = require('body-parser')
const mongoose = require('mongoose')
const app = express();
const urlencodedParser = bodyParser.urlencoded({ extended: false })
app.use(bodyParser.json(), urlencodedParser);
app.use(cors());
const dbURI =
`mongodb+srv://${process.env.REACT_APP_DB_USERNAME}:${process.env.REACT_APP_DB_PASSWORD}@cluster0.sd1id.mongodb.net/register?retryWrites=true&w=majority`
mongoose.connect(dbURI, { useNewUrlParser:true, useUnifiedTopology:true })
.then((res) => {
const User = mongoose.model('users', UsersSchema);
User.createIndexes();
Having issues here I think. Goes straight to error, and not the else loop.
app.post('/register', async (req, res) => {
try {
const user = new User(req.body);
let result = await user.save();
result = result.toObject();
// console.log(result);
if (result) {
delete result.password;
res.send(req.body);
// console.log(result);
} else {
console.log("User already registered!");
}
} catch (e) {
console.log("Something went wrong!");
}
})
})
.catch(err => console.log(err))
const UsersSchema = new mongoose.Schema({
email: {
type: String,
unique: true,
required: true,
},
password: {
type: String,
required: true,
}
})
app.listen(3001, () => console.log("Server is listening to port 3001"))
There is a bit of confusion in your code...
app.js
require('dotenv').config()
const express = require('express')
const cors = require('cors')
const bodyParser = require('body-parser')
const mongoose = require('mongoose')
const app = express();
const createUser = require('registerController');
// repleace 3000 with a port number of your choice
const port = 3000 || process.env.PORT;
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
app.use(cors());
app.post('/register', createUser);
const dbURI =
`mongodb+srv://${process.env.REACT_APP_DB_USERNAME}:${process.env.REACT_APP_DB_PASSWORD}@cluster0.sd1id.mongodb.net/register?retryWrites=true&w=majority`
mongoose.connect(dbURI, { useNewUrlParser:true, useUnifiedTopology:true })
.then(() => {
app.listen(port, () => console.log(`Server listening on Port ${port}`));
});
User.js
const mongoose = require('mongoose');
const userSchema = new mongoose.Schema({
email: {
type: String,
unique: true,
required: true,
},

}
});
module.exports = mongoose.model('User', userSchema);
registerController.js
const User = require('User');
const createUser = async (req, res) => {
try {
const user = await User.create(req.body);
// console.log(user);
if (user) {
delete user.password;
res.send(req.body);
// console.log(user);
} else {

}
} catch (e) {

};
module.exports = createUser;
