    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

    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 (TH-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 TH-cam channel. Merci beaucoup once again!

    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

    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!

      @@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)

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.

    Instead I just checked the condition (req.user && req.user.isAdmin) to see if the user exists and not throw "isAdmin is not defined".

      @@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!

      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));
