# MERN - REDUX (CRUD)- BACKEND
This is a Full-Stack web app with CRUD operations created using Redux for state management and it allows users to Create, Read, Update, and Delete, Recipe CRUD's fields: recipeName, ingredients, and description. It is built using a modern tech stack, including React, MongoDB, Vite, Bootstrap, Express, and Node.js.
## Features
- Create
- Read
- Update
- Delete
## Tech Stack
- **Frontend:**
- React
- Vite
- Bootstrap CSS
- **Backend:**
- Express
- Node.js
- MongoDB
**To run the project,
- clone both Frontend and Backend to the same directory.(https://github.com/MADHURANGA-SKP/MERN-Frontend)
- then open it using IDE(VS code).
## Frontend
- open the terminal then change the current working directory to Frontend, type "npm install" and press enter, then installation, installs all relevant packages and any packages that Frontend depends on.
- then to start the Frontend type "npm run dev" Then it will start your development server on a specific PORT.
## Backend
- open the terminal then change the current working directory to Backend, type "npm install" and press enter, then installation, installs all relevant packages and any packages that Backend depends on.
- before start your development server, you must install MongoDB compass, and make the connection with the database with mongodb provided connection string to adding it to index.js files.
- it looks like this mongoose.connect("mongodb+srv://@cluster.xxxxxx.mongodb.net/crud");
- if you haven't created Mongodb atlas you have to create your own database to accomplish the above steps, you can make that by following this link "https://www.mongodb.com/docs/atlas/getting-started/"
- you have to add your database USERNAME & PASSWORD to this section like this USERNAME:PASSWORD.
- then start your development server by typing "nodemon index.js" Then it will start your development server on a specific PORT.
## Preview
## Functionality
**const express = require("express")**
- Imports the Express.js framework.
**const app = express()**
- Creates an Express application.
## Middleware Setup
**app.use(cors())**
- Enables cors middleware for enable Cross-Origin Resource Sharing.
**app.use(express.json())**
- Middleware to parse incoming JSON data.
## Database Connection
**mongoose.connect("mongodb+srv://:@cluster5.zzu4wuw.mongodb.net/crud")**
- Connects to a MongoDB database using the Mongoose library and a connection string.
**app.get("/", ...)**
- Handles a GET request to the root route
**app.post("/create", ...)**
- Handles a POST request to the "/create" route
**app.put("/update/:id", ...)**
- Handles a PUT request to the "/update/:id" route
**app.delete("/deleteuser/:id", ...)**
- Handles a DELETE request to the "/deleteuser/:id" route
## Server Start
- app.listen(3001, ...)
- Starts the Express application and makes it listen on port 3001. Displays a message once the server is running.
## Module
sets up a Mongoose schema with three fields for a MongoDB collection named "users": recipeName, ingredients, and description.
It then creates a Mongoose model (RecipeModel) based on this schema.
Then exports the model for use in other parts of the application, allowing interaction with the MongoDB collection
