This project is a RESTful API for a blogging platform. It allows users to register, login, create, update, delete, and fetch blog posts. Users can also view published blogs and search for blogs by various filters. The API uses JWT for authentication and MongoDB for data storage.
- User registration and authentication (JWT-based, token expires after 1 hour)
- CRUD operations for blog posts
- Blog post state management (draft, published)
- Pagination, filtering, and sorting for blog posts
- Reading time calculation for blog posts
- Logging with Winston
- Comprehensive tests for all endpoints
- Node.js
- Express.js
- MongoDB
- Mongoose
- JWT for authentication
- bcrypt for password hashing
- dotenv
- nodemon
- Winston for logging
- Jest and Supertest for testing
-
Clone the repository:
git clone https://github.com/Kemi-Oluwadahunsi/intermediate-backend-exam.git cd blog-api -
Install dependencies:
npm install
-
Set up environment variables:
Create a
.envfile in the root of the project and add the following:PORT = 8000 (if you want to run it on your local machine) JWT_SECRET=your_jwt_secret_can_be_any_word_or_phrase MONGO_URI=your_mongo_connection_string -
Run the application:
npm run dev
This includes routes for user registration and login. A JWT token is generated after a user logs in successfully.
-

This shows the relationship between the user and the blog creation. A user can create as many blogs as possible, and can perform blog operations.
- Use tools like Postman or curl to test API endpoints.
- Ensure proper authentication and authorization for protected routes.
- Install Dependencies: Be sure to have installed dependencies by running npm install.
- Run this command in terminal
npm test- The tests are organized into different files within the tests directory. Each file contains tests for specific parts of the application like the user and blog controller files.
