In this repository, I practiced building REST APIs using Node.js, Express, and MongoDB. Here's a brief overview of tasks completed in each homework assignment:

Homework 1:

• Implemented a command-line interface (CLI) for managing a contact list using the commander package.
• Validated user input and interacted with a JSON file to store contact data.

Homework 2:

• Extended the project to create a REST API for managing contacts.
• Integrated Express.js for handling HTTP requests and responses.
• Implemented endpoints for listing, adding, removing, and updating contacts.
• Utilized Joi for request body validation and organized the codebase into controllers, services, and schemas.

Homework 3:

• Set up MongoDB Atlas, created a database, and imported data using MongoDB Compass.
• Integrated Mongoose to interact with MongoDB and replaced file storage with database storage.
• Implemented additional functionality to update the favorite status of contacts.

Homework 4:

• Implemented user authentication and authorization using JSON Web Tokens (JWT).
• Added registration and login endpoints, password hashing, and token verification.
• Implemented middleware for token verification and added routes for user logout and getting current user data.

Homework 5:

• Added email verification for user registration using the SendGrid service.
• Integrated the SendGrid API for sending emails with verification tokens.
• Implemented an endpoint for verifying user emails and functionality for resending verification emails.

Homework 6:

• Integrated image upload functionality using Multer for user avatars.
• Created endpoints for uploading and updating user avatars, processing images with Jimp, and saving them in a public directory.
• Implemented email confirmation after user registration using SendGrid or nodemailer as an alternative.
