Workout MERN App

This is a simple Workout app designed for managing workouts with ease. The app is built using the MERN (MongoDB, Express, React, Node.js) stack and supports essential CRUD (Create, Read, Update, Delete) operations. It utilizes MongoDB for database management, Express and Node.js for server-side functionality, and React for a dynamic front-end user experience.

This project was built following the below tutorials:

Branches

- master: components, react-context, auth
- react-context: components, react-context
- no-state-management: components

Getting Started

This project is divided into two main parts: the backend and the frontend. Follow these steps to set up and run both parts of the application.

Prerequisites

Node.js
MongoDB

Cloning the Repo

Open your terminal or command prompt.

Clone the repository using Git:

git clone https://github.com/arsy786/workout-mern-app.git

Navigate to the cloned repository's root directory
```
cd workout-mern-app
```

Setting up the Backend

From the root directory, navigate to the backend directory:
```
cd backend
```
Install the required Node.js modules:
```
npm install
```

Create a .env file in the backend directory and add the following:

PORT=4000
MONGO_URI=<Your MongoDB connection string>
SECRET=<Your JWT secret key>

For example:

PORT=4000
MONGO_URI=mongodb://localhost:27017/workout-mern-app
SECRET=secret

Start the backend:
```
npm run dev
```
The backend should now be running on http://localhost:4000.

Setting up the Client

Open a new terminal or command prompt window.
From the root directory, navigate to the frontend directory:
```
cd frontend
```
Install the required Node.js modules:
```
npm install
```
In the package.json file in the frontend directory, add the following:
```
  "proxy": "http://localhost:4000",
```
This proxy setting forwards API requests to the backend server running on port 4000. For example, when the React app makes an API request like fetch('/api/data'), it will actually be routed to http://localhost:4000/api/data due to the proxy configuration.
Start the frontend:
```
npm run start
```
The frontend should now be running on http://localhost:3000.

Accessing the Application

After starting both the backend and frontend servers, you can access the web application by navigating to http://localhost:3000 in your web browser. Ensure both servers are running concurrently to allow the frontend to communicate with the backend effectively.

Backend

The backend provides a REST API for managing workouts & users. Here are the available endpoints:

- GET /api/workouts - Get all workouts
- GET /api/workouts/:id - Get a workout by ID
- POST /api/workouts - Create a new workout
- PATCH /api/workouts/:id - Update a workout by ID
- DELETE /api/workouts/:id - Delete a workout by ID

- POST /api/user/signup - Register a new user
- POST /api/user/login - Login a user

The API requires user authentication with JSON Web Tokens (JWT). To authenticate a user, send a POST request to /api/user/login with a JSON body containing the email and password fields. The server will respond with a JWT, which should be included in subsequent requests to protected endpoints.

Frontend

The app provides the following features:

- View a list of workouts
- Create a new workout
- Update a workout
- Delete a workout
