A simple blog application built with Node.js, Express, and MongoDB. The application allows users to create, read, and delete blog posts. Only authenticated users with a valid JWT token can create a blog, and only the user who created a blog can delete it.

• Node.js (version X.X.X or higher)
• npm (version X.X.X or higher)
• A MongoDB database (local or remote)

First, install the required dependencies for the project:

npm install

Create a .env file in the root directory of the project with the following content:

MONGODB_URI = <YOUR-MONGODB-URI>
TEST_MONGODB_URI = <YOUR-TEST-MONGODB-URI>
NODE_ENV = test
PORT = 3001
JWT_SECRET = <YOUR-JWT-SECRET>

Replace the placeholder values (<YOUR-MONGODB-URI>, <YOUR-TEST-MONGODB-URI>, <YOUR-JWT-SECRET>) with your actual MongoDB connection strings and JWT secret.

To start the application in the development environment:

npm run dev

To start the application in the production environment:

npm start

To start the application in the test environment and run the tests:

npm run test

• GET http://localhost:3001/api/posts
  Retrieves all blog posts.

• POST http://localhost:3001/api/posts
  Creates a new blog post.
  Note: Requires a valid JWT token in the Authorization header.

• DELETE http://localhost:3001/api/posts/:id
  Deletes a blog post by ID.
  Note: Only the user who created the blog can delete it, and a valid JWT token is required.

• GET http://localhost:3001/api/users
  Retrieves all users.

• POST http://localhost:3001/api/users
  Registers a new user.

• POST http://localhost:3001/api/login
  Authenticates a user and returns a JWT token.

The application uses JWT (JSON Web Token) for authentication. Users must include a valid JWT token in the Authorization header as a Bearer token to create or delete blog posts.

• Replace <YOUR-MONGODB-URI>, <YOUR-TEST-MONGODB-URI>, and <YOUR-JWT-SECRET> with your actual MongoDB connection strings and JWT secret.
