MEFN (MongoDB, Express.js, Flutter, Node.js) Project

This repository contains a basic crud todo app made using MongoDB, Express.js for the backend, and Flutter for the frontend.

Backend Setup

Prerequisites

Node.js (with npm)
MongoDB

Getting Started with Backend

Clone the repository:

git clone https://github.com/basedharsh/MEFN.git
cd MEFN

Install backend dependencies:
```
cd backend
npm install
```
Set up MongoDB:

Make sure MongoDB is installed and running. If not installed, download and install it from MongoDB Download Center.

Configure MongoDB connection:

Inside your backend code (in backend/src/server.ts), ensure you have your MongoDB connection configured. Example:

const mongoose = require('mongoose');

// Connect to MongoDB
mongoose.connect('mongodb://localhost:27017/mydatabase', {
  useNewUrlParser: true,
  useUnifiedTopology: true,
  useCreateIndex: true,
});

const db = mongoose.connection;
db.on('error', console.error.bind(console, 'MongoDB connection error:'));
db.once('open', () => {
  console.log('Connected to MongoDB');
});

// Your Express.js server setup continues here...

Replace 'mongodb://localhost:27017/mydatabase' with your actual MongoDB connection string.

Run the backend server:
```
npm start
```
This will start the backend server. By default, it will run on http://localhost:3000.

Flutter Frontend Setup

Prerequisites

Flutter SDK
Android Studio / Xcode (for simulator/emulator) or a physical device for testing

Getting Started with Flutter Frontend

Navigate to the Flutter project:
```
cd ../flutter_project_directory
```
Replace ../flutter_project_directory with the actual path to your Flutter project directory.
Set up Flutter environment:

Make sure you have Flutter SDK installed. If not, follow the official Flutter installation guide.
Configure Flutter frontend:

Create lib/config.dart within your Flutter project, set the backend API URL:
```
class Config {
  static const String baseUrl = 'http://localhost:3000/api';
}
```
Replace 'http://localhost:3000/api' with your actual backend API URL if you changed port or something or let it be.
Run the Flutter application:

Connect your mobile device or start an emulator/simulator and run:
```
flutter run
```
This command builds and runs the Flutter application on your connected device or emulator.

Additional Notes

Ensure MongoDB is running (mongod command) before starting the backend server.
Adjust firewall settings if necessary to allow connections to MongoDB and your backend server.

This README.md file now provides detailed steps for setting up both the backend (MongoDB, Express.js) and the Flutter frontend
