I'm using mongodb to store the details. I am aware that this question has already been asked, but the solutions did not work for me.
const userSchema = {
email: {type: String, unique: true},
password: String
};
I used the schema I entered above, and it kind of works, what I mean is, it doesn't let duplicate entries to be inserted into the database. But the problem I have is, that it doesn't get any error, so I'm not able to use the following code.
if(err){
console.log("Repeated record");
}
Since there is no error, the page continues to load, for about 2-3 minutes, and finally it says "The page isn't working, localhost didn't send any data." Can someone please let me know what approach I should be taking to achieve this.
Edit: This is the server code:
app.get("/", function(req, res){
res.render("home");
});
app.get("/login", function(req, res){
res.render("login");
});
app.get("/register", function(req, res){
res.render("register");
});
app.post("/register", function(req, res){
const newUser = new User({
email: req.body.username,
password: req.body.password
});
newUser.save(function(err){
if(err){
console.log(err);
}else{
res.render("login");
};
});
});
app.post("/login", function(req, res){
const username = req.body.username;
const password = req.body.password;
User.findOne({email: username}, function(err, foundUser){
if(err){
console.log(err);
}else{
if(foundUser){
if(foundUser.password == password){
res.sendFile(__dirname + "/public/upload.html");
}
}
}
});
});
I have installed express, body-parser and ejs. Home, login and register are templates of the extension .ejs .
Thank you.
You have to send response to client if error or something else occurred. Otherwise your function won't send any data. I added some comment lines into your code as marked as --> Here. Use res.send() or res.render() in these functions to send response to your client side.
Also adding status code may be helpful for understanding error code (just suggestion).
app.post("/register", function(req, res){
const newUser = new User({
email: req.body.username,
password: req.body.password
});
newUser.save(function(err){
if(err){
console.log(err);
// res.status(422).send(err) or res.render(errorPage) --> Here
}else{
res.render("login");
};
});
});
app.post("/login", function(req, res){
const username = req.body.username;
const password = req.body.password;
User.findOne({email: username}, function(err, foundUser){
if(err){
console.log(err);
// res.status(500).send(err) or res.render(errorPage); --> Here
}else{
if(foundUser){
if(foundUser.password == password){
res.sendFile(__dirname + "/public/upload.html");
} else {
// res.status(401).send('Some error message') res.render(errorPage); --> And here
}
}
}
});
});
