Description

Task

Install and configure Express.js and required dependencies for the hero API

Acceptance Criteria

• Express.js successfully installed
• Basic server configuration complete
• Development scripts configured
• TypeScript integration working
• Basic error handling in place

Summary of Work

Purpose

This pull request sets up the initial Express.js configuration for the Hero API project, establishing the foundational infrastructure for our API development.

Changes Made

1. Express.js Configuration

• Installed Express.js dependency
• Configured basic Express application in src/index.ts
• Set up PORT configuration with environment variable fallback
• Added JSON middleware for request parsing
• Implemented root endpoint with basic health check

2. Development Dependencies

• Added TypeScript support
• Configured Jest for testing
• Added development tools like nodemon and ts-node

Implementation Details

• Root endpoint (/) returns a simple JSON message
• PORT is dynamically set from environment or defaults to 3000
• Express.json() middleware added for parsing JSON payloads
• TypeScript configuration ensures type safety
• Modular project structure established

Testing Approach

• Basic application startup test implemented
• Root endpoint returns expected JSON response
• Environment variable PORT handling verified

Considerations

• Future endpoints will be added incrementally
• Logging and advanced error handling to be implemented in subsequent PRs
• Continuous integration setup pending

Changes Made

• Configured src/index.ts with basic Express setup
• Added TypeScript and testing dependencies
• Created basic root endpoint
• Configured PORT handling

Tests
