Go Coding Challenges

This repository contains my solutions to real-world coding challenges from codingchallenges.fyi, implemented in Go.

🚀 Completed Challenges

1. wc Tool

Recreate the classic Unix wc tool to count lines, words, characters, and bytes in files.

2. url shortener

Build my own URL shortening service with URL deduplication and multiple backends.

🔧 CI/CD

This repository uses GitHub Actions for continuous integration. The workflow automatically:

• Runs tests and builds for all Go projects
• Runs linting with golangci-lint

Adding New Projects

To add a new Go project to the CI pipeline, add your-new-project name to the matrix in .github/workflows/go.yml:

strategy:
  matrix:
    project: [url-shortener, wc, your-new-project]

1. Ensure your project has:
   • A valid go.mod file
   • Tests (run with go test ./...)
   • A buildable main package (run with go build ./...)

All projects run concurrently for faster CI execution.
