# ⭐CRUD Note Backend App⭐

⭐Introduction:

• This Node.js application, built with Express, offers a robust backend for a CRUD (Create, Read, Update, Delete) Note application. It leverages a microservice architecture for user authentication, note management, and API routing.

⭐Features:

• ✅ User Authentication:
  • Users can register for new accounts.
  • Login with existing credentials grants a secure password.
• ✅ Note Management:
  • Create new notes.
  • Advanced search capabilities (e.g., full-text search, filtering by tags).
  • Update existing notes.
  • Delete notes.
  • Secured access:
  • Logged-in users can only see their private notes.
  • Public notes are visible to everyone.
• ✅ Microservices Architecture:
  • Gateway: Handles user authentication and API routing.
  • User Microservice: Manages user creation and login functionalities.
  • Note Microservice: Handles all note-related operations (CRUD).
• ✅ Domain and Data Layers:
  • Each microservice implements a clean separation between domain logic (business rules) and data access (interaction with MongoDB).
• ✅ Fully test:
  • The app is tested to make sure it is robust.

⭐Technology Stack:

• ✅ Node.js
• ✅ Express.js
• ✅ MongoDB

⭐Installation:

1. Clone this repository:

   git clone https://github.com/itaishalom/NoteServerEx

2. Install dependencies:

   cd NoteServer
   npm install

Configuration:

1. Create a .env file in the project root directory.
2. Add environment variables for database connection details and any other necessary configurations.

Running the Application:

Important: You need to run all three microservices for the application to function properly. However, the User and Note services should be run with unexposed ports for security reasons.

1. Gateway Service:

   node index.js

2. User Microservice (Unexposed Port):

   node index.js

3. Note Microservice (Unexposed Port):

   node index.js

Usage:

• Refer to API documentation (consider using tools like Swagger for a more interactive experience). ⭐
• Implement client-side applications (web or mobile) to interact with the backend API. ⭐
