No Docker Support, Missing Global Error Middleware, Bad Folder Structure

[Maheshghosh]

1. use this
   FROM node:20-alpine

WORKDIR /app

COPY package*.json ./

RUN npm install

COPY . .

RUN npm run build

EXPOSE 5000

CMD ["npm", "start"]

2. FIX THE SECOND PROBLEM
   export const errorHandler = (
   err,
   req,
   res,
   next
   ) => {
   console.error(err);

res.status(err.status || 500).json({
success: false,
message: err.message || "Internal Server Error",
});
};

3. Change to moderate structure
