What Should I Build as a Beginner Gopher?

At this initial stage, the primary goal is to familiarize yourself with Go’s syntax, set up your Go environment, and choose a comfortable Integrated Development Environment (IDE). Hands-on practice is invaluable.

Beginner Project Recommendation: Age Calculator CLI App

1. CLI Application: Create a command-line interface (CLI) application.
2. Input Request: Upon running, the program should prompt the user to enter their date of birth.
3. Age Calculation: Calculate the user’s age based on the input.
4. Output Display: Print the calculated age back to the console.
5. Standard Library Only: Restrict yourself to using only the Go Standard Library. Avoid third-party libraries to deepen your understanding of Go’s built-in capabilities.

Completing this project independently signifies:

• Successful Go environment setup, including IDE configuration.
• Proficiency in navigating the Go Standard Library documentation.
• Ability to create a basic CLI and handle user input in Go.
• Successful execution of go run commands.

For additional beginner project ideas, explore resources like Coding Challenges. The “WC” (Word Count) task is a suitable challenge at this level to further solidify your foundational skills.

Listen and Learn Go for Beginners

• Go Time Podcast (changelog.com/gotime): While Go Time covers a range of Go topics, listening to beginner-friendly episodes can provide insights into the Go community and language discussions.
• “Learning Go” audiobooks: Consider audio versions of beginner Go books for learning on the go, during commutes, or while performing other tasks.

Junior Project Recommendation: Exchange Rate Server

Requirements:

• HTTP Server: Develop an HTTP server using Go’s net/http package.
• Currency Exchange Endpoint: Create an endpoint that accepts a currency pair, for example, /exchange/GBP/USD.
• Exchange Rate Data: For the given currency pair, the server should:
  • Fetch and display today’s exchange rate.
  • Retrieve and list exchange rates for the past 7 days.
  • Provide a simple, naive indicator of whether “today is a good day to buy” the second currency in the pair relative to the first.
• Naive “Good Day to Buy” Logic: Implement a basic algorithm to determine if it’s a “good day to buy.” A simple approach is to average the exchange rates from the past 7 days and compare it to today’s rate. If today’s rate is lower than the average, it could be considered a “good day to buy.”

Commentary:

Refer to the Go team’s official guidance on project layout for structuring your Go projects effectively. Also, study Dave Cheney’s article on table-driven tests to implement robust and well-structured testing in your project.

For more challenging project ideas at this level, consider tasks from Coding Challenges. Building your own Spotify Client is a substantial and rewarding project for a junior Go developer, pushing you to interact with APIs and handle more complex data structures.
