BackEnd MicroServices

This project consists of a set of microservices built using Node.js and Express.js. Below is an overview of the project structure and functionality of each microservice:

Project Structure

The project consists of the following files and directories:

• DB: Contains database-related files.
• uploads: Directory for file uploads.
• views: Contains HTML files for the microservice landing pages.
• index.js: Entry point for the application.
• .env: Configuration file for environment variables.
• README.md: This file.

Microservices Overview

1. Timestamp Microservice Routes: /timestamp: HTML router. /timestamp/api/: API endpoints for timestamp functionality. /timestamp/api/: Returns current UTC and UNIX timestamp. /timestamp/api/:date: Returns UTC and UNIX timestamp for the provided date.
2. Request Header Parser Microservice Routes: /requestHeaderParser/api/whoami: Returns IP address, user agent (software), and preferred language.
3. URL Shortener Microservice Routes: /urlShortenerMicroservice: HTML router. /api/shorturl/all: Get all short URLs stored in the database. /api/shorturl: POST endpoint to shorten a URL. /api/shorturl/:code: GET endpoint to redirect to the original URL using the short code. /api/shorturl/:shortcode: PUT and DELETE endpoints to update or delete a short URL.
4. Exercise Tracker Microservice Routes: /exerciseTrackerMicroservice: HTML router. /exerciseTrackerMicroservice/api/users: GET all users or CREATE a new user. /exerciseTrackerMicroservice/api/users/:_id/logs: GET logs for a specific user. /exerciseTrackerMicroservice/api/users/:_id/exercises: POST a new exercise for a user. /exerciseTrackerMicroservice/api/users/:_id/delete: DELETE a user.
5. File Metadata Microservice Routes: /fileMetadataMicroservice: HTML router. /fileMetadataMicroservice/api/fileanalyse: POST endpoint to upload a file and retrieve metadata. Setting Up the Project Install dependencies: Run npm install. Configure environment variables: Create a .env file and set up necessary variables. Start the server: Run npm start.

Notes

• The project utilizes Express.js for routing and middleware handling.
• Multer is used for file uploads in the File Metadata Microservice.
• MongoDB is used as the database for storing short URLs and exercise tracker data.
