bhai tune, short url project banye hai..?
i like the way you explain and also i learning how to read docs
You make really fantastic videos. I like the way of your teaching and writing the code in efficient manner. wow It's really outstanding...
Few questions:
1. 06:08 Why you used express.Router() instead of express()
2. 12:26 How does this script start working and what is nodemon
3. 11:58 What did you do here, what is this localhost port, and how are you saving the data.
Bro Just watch the tutorial from starting lec-1
bruh you don't even know the basics, I recommend watching from the start dude.
Yes bro watched the node js tutorial from starting these all the basics which you are asking here
Bhai maza aagya. awesome approach 🥳
URL Shortner created Done✅ thanks sir jee

I was getting error with both nanoid and shortid , so I used nanoid@^3.0.0
I am not understanding these fucking topics 😅 what to do bro I am not liking can u suggest what u are doing now
Is it working ?

thanks buddy , i have full of respect for you my man , i have wasted 3 hrs to solve that fucking bug
@@devascript I too man, that’s why I posted this comment so that people watching in future won’t have to waste time on this!!
thanks man this bug was way difficult to find I just wasted quite some time on this 😡
Thank you for your great efforts! Really really awesome video.
best series ever
amazing and simple project for beginners like me✨✨
please keep up the classes free on youtube. They are so helpful.
12:50 nanoid is throwing some error, which can be fixed by dunamically importing it -
async function generateNewShortURL(req, res) {
const body = req.body;
if (!body.url) {
return res.status(400).json({
error: "URL is required."
});
}
const { nanoid } = await import('nanoid');
const shortID = nanoid(8); // Generate the short ID
await URL.create({
shortId: shortID,
redirectURL: body.url,
visitHistory: [],
});
return res.json({ id: shortID });
};
Excellent explanation❤
Now my only goal is to be perfectionist like him while my hands on keyboard. ....how much does it take to be pro in backend?
bhai I follow your same code and when i start npm the npm is running also but when i run send url from post man it always saying url is required please helpm me out
thanks bro for the great video
Congrats For 100k MAn
Halat patli ho gyi Bhai yeh project banate banate ...
Kahin khudse banana pad Jaye Bina dekhe fir pata nhi kya ho....
It seems quite difficult right now😮
Same here.. is playlist ki Kitne videos dekh lie aapne abhi tak?
it was not working because nano id supports common js syntax only upto version 3 and we are using version 5
solution : 1) use module syntax instead
2) degrade to version 3
great video bhaiya what will be the next video?
Wait till 5:00PM 💪🏻
nice explanation thanks for great video!!
Sir will you upload react native course please tell me?
Interesting video, nice explanation Thanks
Thanks🧡, nice video
Bhaiya can you please make a video on tracking the IP of the client in the analytics. As I was reading about this feature, this seams to be tricky in the case of proxy or load balancers.
Nice video bhaiya
i tried using nanoid and shortid for once post request works but when i try to make second its giving duplicate error, it's not generating unique shortID and get request for /:shortID also does not work
const URL = require("../models/url");
async function handleGenerateNewShortURL(req, res) {
const { nanoid } = await import("nanoid");
const body = req.body;
if (!body.url) return res.status(400).json({ error: "url is required!" });
const shortID = nanoid(8);
await URL.create({
shortId: shortID,
redirectUrl: body.url,
visitHistory: [],
});
return res.json({ id: shortID });
}
module.exports = { handleGenerateNewShortURL };
if(!body.url){ return res.json({error:"URL Needed"}) }

Any one ??
Included app.use(express.json()) middleware in the index.js?
and make sure that you add on the top of url roure
18:02 bhai ye entry par hover karne suggestions kaise aaya?
Koi extension ho to batao!!
sir postman not connect error 404 but code is same please provde same code
pls give some basic knowledge on mongodb also ...i feel its going fast in between
I am getting this error when I use generated shortid url in search bar:

TypeError: Cannot read properties of null (reading 'redirectURL')
This might solve the issue: (entry?.redirectURl)
Your two routes are clashing.
@@niteshkushwaha9493 then how to solve this ?
could be an unresolved promise, are you sure you are using async await or .then right?
So For This I will Give Solution which is
const entry = await Url.findOneAndUpdate({
shortId,
}, {
$push: {
visitHistory: {
timestamp: Date.now(),
}
}
});
res.redirect(entry.redirectURL);
})
Error is if you are Give if there are nothing return by entry Because Your name "shortId" is same in Your Schema "shortId " so Your Code will Succesfully Worked
Thanks bro
shortid has been reprecated, any other package recommended?

I understood the code, but I didn't understand the purpose of this app
I mean why do we need short url anyways?

excellent
thanks for the tutorial. I am getting an error. while using findOneAndUpdate It returns null because of which redirect is not working. I tried your code also but it is not working
I am also getting the same error
check if u have exported and imported database properly
@@comparisondata2473 yes imported correctly.
it is the problem of res.redirect , it needs a protocol like http or https otherwise it consider the redirect as a relative path - this will throw out an error
Use this instead
const url=entry.redirectURL.startsWith('') || entry.redirectURL.startsWith('') ? entry.redirectURL :`${entry.redirectURL}` ;
res.redirect(url)
where did you declare urlRoute before importing
Hi there, I am a little bit confused, won't this URL shortner only work on the machine in which npm is running

there is some problem with the code when i try to store a url which doesn't starts with "" or "" it works fine but when i try shout url it behave unexpectedly .
Even the code provide by you has the same problem. But when a url starts with "https:" or "http:" this problem surprisingly doesn't happen.
‼edit: it is the res.redirect( ) , it needs a protocol like http or https otherwise it consider the redirect as a relative path so just append https before the url that stored in your database if it doesn't have any protocol to to that you can use the code here:
const redirectUrl = url.redirectUrl.startsWith('') || url.redirectUrl.startsWith('')
? url.redirectUrl
: `${url.redirectUrl}`;
Bro you solve my problem, but I have 1 more problem I'm not getting code autocomplete or my vscode intellisense is not working for MongoDB what should I do?

how handlegenerateshorturl function get req and res objects?
bhai agar null wali error aa rhi hain toh upr bhai n source code diya hain usko copy marke console m entry print karana error dikh jayegiii tumkoo tumhari..
thanks me later.. bye
shortid is worked
why did we made history as array of objects?
because he wanted to store multiple timestamps to determine the length of url hits and array is used to store multiple entries.
Solution for this error: TypeError: Cannot read properties of null (reading 'redirectURL')
Don't miss out typing along with the url during post request. Hopefully it should work. Worked for me.

I want to become a full-stack developer, and initially, I only knew React.js. Upon searching for Node.js tutorials, I came across your playlist of 48 videos. These videos are incredibly informative, and I had never learned Node.js before. After watching your tutorials, I've become a fan of your teaching style. Thank you so much for guiding us in such a great way!
