Hi friends, I checked your comments in the previous video. And majority of people wanted Node.js and MongoDb as backend. However, that doesn't mean we won't build other apps using different technologies. Let me know in the comments what else you'd like to see for the next projects. Love ya
For those who are getting stuck at 1:46:20 where they are not getting the desired results of 'limit'. You can try this: Use destructuring to get limit and featured from req.query like this---> const {limit,featured}=req.query; and then while fetching data write fetching line like this---> const hotels=await Hotel.find({featured:featured}).limit(limit);. After this getHotels code will be look like this : export const getHotels=async(req,res,next)=>{ try { const {limit,featured}=req.query; const hotels=await Hotel.find({featured:featured}).limit(limit); return res.status(200).json(hotels); } catch (err) { next(err); } } Hope it helps!

@@kumarsrijan7566 next in the function parameter means once completed go to the next middleware function. In this case if you add next in verifyToken function's parameter, the next will refer to the middleware after verifyToken function from the routes -- but your routes doesn't have verifyToken, but it has verifyAdmin, so ideally you want the next () -> to refer to your verifyAdmin, so that the next middleware, which in this case is updateHotel is executed. @01:13:15 Lama said it, that the next is referring to verifyToken --> that is the catch. So if you should add next as an parameter to verifyAdmin middleware function and not the verifyToken middleware function. Hope it helps!
Hi Lama, thank you so much for your wonderful videos, I learned a lot and made my job easier. Also, I have a small suggestion, can you add a difficulty level to each video, like between 1-5? Because after one video, I move on to the next one, but you have so many videos that I don't know which one is right for my skill level. But if you have a difficulty level, it might be easier for me to find the next video to learn from. Hope you can think about it if you have enough time. Thanks

In 02:54:00, if I click reserved, it will push the data into unavailableDate, it pushed the data successfully but it didn't compare the date. For example, I choose the date from 5.27-5.28, then it pushed the date array ['2022-05-26T14:00:00.000Z', '2022-05-27T14:00:00.000Z'], saved, and I choose the same room, same date, and click reserve, it will push the same date array as array1, doesn't compare the date.
Great tutorial and very clear in way of explaining. Hope you don't mind but would love to use certain smaller parts for my project. Your complete project and structure is a great example to learn from, in my opinion. Thank you so much for your contribution in my learning path. Will try to watch more videos when manage to have some free time. Thank you once again.
So glad you chose the MERN architecture for the project.. God bless you.. Pls can you add one last series in the video that involves email notifications or text message notification when a reservation is made for both the user and the admin.. and finally can you upload the project with a domain on a server.. I would be very grateful if any of this feature I requested above is implemented.. thank you in advance . I appreciate the impact once more...

I am learning a lot from you. I think your first approach was right for not using ''next'' in verifyToken under verifyUser and verifyAdmin function. Because, now it will go to next outer function instead of inner function, if I understood correctly.
@@hershey92 Hi bro not sure if you still need this but I had the same issue and figured it out, I think. Inside of the verifyUser function we call verifyToken, which takes 3 parameters: req, res and next. if you give it 4 parameters in the nested function it will not executed the callback function and it will go directly to the next middleware(updateUser, updateHotel etc etc). however if no cookie is in place it will have no information for req.user.admin( which is required in the body of the nested callback). anyways it is solved by checking of req.user exists. I am just a humble intern so I think this is how it works, pls correct me if I am wrong, anyway my code works as it should. export const verifyUser = (req,res,next) =>{ verifyToken(req,res,()=>{ if(req.user.id === req.params.id ||req.user?.isAdmin){ console.log(req.user.isAdmin) next() }else{ return next(createError(403, "You are not autorized")) } }) } export const verifyAdmin = (req,res,next) =>{ verifyToken(req,res,()=>{ if(req.user?.isAdmin){ next() }else{ return next(createError(403, "You are not admin autorized")) } }) }
If you get an error at 1:36:57 , what you need to do ? ıts so simple ; After changing the proxy, stop the client with ctrl + c and run it again by npm start. and then The problem is solved and the result of console.log(data) appears as 3
if you have a problem at 3:25:05 you can do this. for cloud_name firstly you have to go cloudinary and then sign in. then you will go dashboard and you can see your cloud_name. instead of demo you can write this cloud name. and then problem will be solved
Hi Lama, thanks for the tutorial. At 01:13:16, I noticed that once the 'next' is added to the argument, the function to check 'isAdmin' doesn't run anymore.

Hi @LamaDev, Can you help me at 1:46 as per video I have passed featured=true&limit=2 in the url in thunderclient but my mongodb query returns zero results. Mongodb query not taking limit as limit field instead it is checking for featured=true and limit=2 in database which results zero result and there is no field like limit in the table.
just destructure the req.params for one more value limit and use it in limit part of hotels.find function so right now we have const{min,max,...others}=req.query and change it to const{min,max,limit,...others}=req.query and in the Hotels.find function change the part "limit(req.query.limit)" to "limit(limit)"
Nice Job Lama! Your projects are really inspiring and has been of great help to me. I think the next tutorial should be on making "An appointment booking website using react". I already made a research on this (UA-cam & internet generally) and the ones I found are either made in WordPress or employed a plug-in. I think making this could really be helpful to take this channel to it next bigger audience as you could possibly be the first to implement it on a UA-cam channel. Merci beaucoup once again!
Are you talking like one that interacts directly with your webcam? That would be cool. I feel just making the appointments is an easy adaptation from the skills learned in this one.

2:13:24 I have a problem with endDate : Uncaught TypeError: Cannot read properties of undefined (reading 'endDate'); I'll hope anyone here can help with the solution to this bug: Never mind there's no bug, simple just go back to the home page rather than refresh id page. The bug is because there's no date data when u refresh the page as oppose to when u return to the home page and select the date, thus making ur state able to store the date data and pass it to the useContext state react API which can be assess anywhere in the app
Hello. I faced the same issue. And the author further in the video shows how it can be solved. With the help of local storage. Lama wrote this for authentication, and for storing date data - the principle is almost the same. I did it. The main thing is then to replace in the function for the simplicity of days: datex.getTime() with Date.parse(datex). I hope this helps you. //In SearchContext edit INITIAL_STATE like below. const INITIAL_STATE = { city: undefined, dates: JSON.parse(localStorage.getItem("dates")) || [], options: JSON.parse(localStorage.getItem("options")) || { adult: undefined, children: undefined, room: undefined, } } //And in SearchContext in function SearchContextProvider add useEffects like below export const SearchContextProvider = ({children}) =>{ const [state, dispatch] = useReducer(SearchReducer, INITIAL_STATE);
if you are getting "Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client res.status(200).json(hotels)" when you run any of your request on postman, it's because The request handler is simply a javascript function and this means that the javascript engine(v8 in nodes case) keeps executing the code beyond the if statement when there is no explicit instruction for it to exit the function. The simple fix around this is to return your responce. in this case : 'return res.what_ever_it_is'
Hi Lama Dev .. thank you for the time you spend in creating such useful, creative & educative content. May God Bless you Tremendously. Please, Can you do some/add some sought of notification first to the user when a reservation is made stating that "he just made a reservation" and to the admin saying that he has a new message in his dashboard. secondly, can you add features where the user has his own dashboard that helps him fast-track his reservations. Also can payment gateways be incorporated and can the project be hosted on a VPS using Nginx. thank you in advance. I really appreciate the good work. God Bless you once more.

For those that verifyAdmin is not working, that is happening because when we call the func verifyToken it returns a next() at the end, so it enters the route func before even initializing the verifyadmin. I hope it helps
if you are having problems after executing the cookie parser code lines, stop your server and npm install it as 'npm i cookie-parser'. Worked for me and hopefully works for you too.
Hello mate. Have problem im on part Insomnia program. when add city adress and etc. and click to test on insomnia show Cannot POST /api/hotels. Hotel.js is currect. Hotels.js is "import express from "express" import Hotel from "../models/Hotel.js"; const router = express.Router(); //CREATE router.post("/api", async (req,res)=>{ const newHotel = new Hotel(req.body) try{ const savedHotel = await newHotel.save() res.status(200).json(savedHotel) }catch(err){ res.status(500).json(err) } }) //UPDATE //DELETE //GET //GET ALL export default router"
@spikerrbg 22 Check your index.js file. Perhaps your endpoint is wrongly typed. It should be "/api/hotels" not "api/hotels". Also your hotels.js routes file should be '/' for the insomnia to work at 27:02

Hi Lama, thank you so much for your wonderful videos, I learned a lot and made my job easier. Also, I have a small suggestion, can you add a difficulty level to each video, like between 1-5? Because after one video, I move on to the next one, but you have so many videos that I don't know which one is right for my skill level. But if you have a difficulty level, it might be easier for me to find the next video to learn from. Hope you can think about it if you have enough time. Thanks

In 02:54:00, if I click reserved, it will push the data into unavailableDate, it pushed the data successfully but it didn't compare the date. For example, I choose the date from 5.27-5.28, then it pushed the date array ['2022-05-26T14:00:00.000Z', '2022-05-27T14:00:00.000Z'], saved, and I choose the same room, same date, and click reserve, it will push the same date array as array1, doesn't compare the date.
And I tried to print the 'isFound'. it shows undefined, why is it?

@@curious9208 Lama Dev is genius. All the codes works fine 👍
@mriganpegu please share your GitHub
Is it responsive?
@@AnkitKumar-ol7vc Yes 👍
I am learning a lot from you. I think your first approach was right for not using ''next'' in verifyToken under verifyUser and verifyAdmin function. Because, now it will go to next outer function instead of inner function, if I understood correctly.
yes agreed!
there is the same problem which I was solving :D
can you please explain this to me? We aren't invoking the next function by adding () but it's still sending it out of the verifyUser function. How?
How it solve it? Can anyone help me?
@@hershey92 Hi bro not sure if you still need this but I had the same issue and figured it out, I think. Inside of the verifyUser function we call verifyToken, which takes 3 parameters: req, res and next. if you give it 4 parameters in the nested function it will not executed the callback function and it will go directly to the next middleware(updateUser, updateHotel etc etc). however if no cookie is in place it will have no information for req.user.admin( which is required in the body of the nested callback). anyways it is solved by checking of req.user exists.
I am just a humble intern so I think this is how it works, pls correct me if I am wrong, anyway my code works as it should.
export const verifyUser = (req,res,next) =>{
verifyToken(req,res,()=>{
if(req.user.id === req.params.id ||req.user?.isAdmin){
console.log(req.user.isAdmin)
next()
}else{
return next(createError(403, "You are not autorized"))
}
})
}
export const verifyAdmin = (req,res,next) =>{
verifyToken(req,res,()=>{
if(req.user?.isAdmin){
next()
}else{
return next(createError(403, "You are not admin autorized"))
}
})
}
By placing the question markt there it will return false if its undefined
Another awesome project Lama. You're the best.
If you get an error at 1:36:57 , what you need to do ? ıts so simple ; After changing the proxy, stop the client with ctrl + c and run it again by npm start. and then The problem is solved and the result of console.log(data) appears as 3
what if i use vite for react application
if you have a problem at 3:25:05 you can do this. for cloud_name firstly you have to go cloudinary and then sign in. then you will go dashboard and you can see your cloud_name. instead of demo you can write this cloud name. and then problem will be solved
Hi Lama, thanks for the tutorial. At 01:13:16, I noticed that once the 'next' is added to the argument, the function to check 'isAdmin' doesn't run anymore.
True, try removing the 'next' parameter in verifyToken inside verifyAdmin / verifyUser
@@kennedymwangi5880 Heyyy...could you please elaborate...I'm stuck here..
if (!req.user) {
return res.send('No user token is availible.');

i remove next and added this at the top of the function,now it seems cool..
@@jswarrior_ whats function?
Replace the both verifyAdmin and verifyUser functions with these:
export const verifyAdmin = (req, res, next) => {
verifyToken(req, res, () => {
if (req.user.isAdmin) {
next();
} else {
return next(createError(403, "You are not authorized!"));
}
});
};
export const verifyUser = (req, res, next) => {
verifyToken(req, res, () => {
if (req.user.id === req.params.id || req.user.isAdmin) {
next();
} else {
return next(createError(403, "You are not authorized!"));
}
});
};

Hi @LamaDev, Can you help me at 1:46 as per video I have passed featured=true&limit=2 in the url in thunderclient but my mongodb query returns zero results. Mongodb query not taking limit as limit field instead it is checking for featured=true and limit=2 in database which results zero result and there is no field like limit in the table.
i have a same issue
just destructure the req.params for one more value limit and use it in limit part of hotels.find function so right now we have const{min,max,...others}=req.query and change it to const{min,max,limit,...others}=req.query and in the Hotels.find function change the part "limit(req.query.limit)" to "limit(limit)"

Nice Job Lama! Your projects are really inspiring and has been of great help to me. I think the next tutorial should be on making "An appointment booking website using react". I already made a research on this (UA-cam & internet generally) and the ones I found are either made in WordPress or employed a plug-in. I think making this could really be helpful to take this channel to it next bigger audience as you could possibly be the first to implement it on a UA-cam channel. Merci beaucoup once again!
Yes this is a great idea. I’ve been looking for a similar project.
Are you talking like one that interacts directly with your webcam? That would be cool. I feel just making the appointments is an easy adaptation from the skills learned in this one.

2:13:24 I have a problem with endDate : Uncaught TypeError: Cannot read properties of undefined (reading 'endDate'); I'll hope anyone here can help with the solution to this bug: Never mind there's no bug, simple just go back to the home page rather than refresh id page. The bug is because there's no date data when u refresh the page as oppose to when u return to the home page and select the date, thus making ur state able to store the date data and pass it to the useContext state react API which can be assess anywhere in the app
Hello. I faced the same issue. And the author further in the video shows how it can be solved. With the help of local storage. Lama wrote this for authentication, and for storing date data - the principle is almost the same. I did it. The main thing is then to replace in the function for the simplicity of days: datex.getTime() with Date.parse(datex). I hope this helps you.
//In SearchContext edit INITIAL_STATE like below.
const INITIAL_STATE = {
city: undefined,
dates: JSON.parse(localStorage.getItem("dates")) || [],
options: JSON.parse(localStorage.getItem("options")) || {
adult: undefined,
children: undefined,
room: undefined,
}
}
//And in SearchContext in function SearchContextProvider add useEffects like below
export const SearchContextProvider = ({children}) =>{
const [state, dispatch] = useReducer(SearchReducer, INITIAL_STATE);
useEffect(()=>{
localStorage.setItem("dates", JSON.stringify(state.dates));
}, [state.dates]);
useEffect(()=>{
localStorage.setItem("options", JSON.stringify(state.options));
}, [state.options]);
return (
{children}
)
};
//At last in component Hotel.jsx change dayDifference function
const dayDifference = (date1, date2)=>{
const timeDiff = Math.abs(Date.parse(date2) - Date.parse(date1));
const diffDays = Math.ceil(timeDiff / MILLISECONDS_PER_DAY);
return diffDays;
};

Thanks Lama. Finished it a while ago. It felt a bit rushed at the end but it was a nice tutorial.
if you are getting "Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client
res.status(200).json(hotels)" when you run any of your request on postman, it's because The request handler is simply a javascript function and this means that the javascript engine(v8 in nodes case) keeps executing the code beyond the if statement when there is no explicit instruction for it to exit the function. The simple fix around this is to return your responce.
in this case : 'return res.what_ever_it_is'

Hi Lama Dev .. thank you for the time you spend in creating such useful, creative & educative content. May God Bless you Tremendously. Please, Can you do some/add some sought of notification first to the user when a reservation is made stating that "he just made a reservation" and to the admin saying that he has a new message in his dashboard. secondly, can you add features where the user has his own dashboard that helps him fast-track his reservations. Also can payment gateways be incorporated and can the project be hosted on a VPS using Nginx. thank you in advance. I really appreciate the good work. God Bless you once more.

I resolved it by just putting the url as :localhost:8800/hotel
@spikerrbg 22 Check your index.js file. Perhaps your endpoint is wrongly typed. It should be "/api/hotels" not "api/hotels". Also your hotels.js routes file should be '/' for the insomnia to work at 27:02
