Questions & Answers

Q: What motivated the author to revisit the Go programming language?

The author felt an itch to learn a new programming language after not touching Go for a while and was encouraged by the simplicity of Go compared to Rust. They previously had some exposure to Go and wanted to refresh their skills by building a REST API.

Q: How does one set up a Go module for a new project?

To create a Go module, the author recommended using the command go mod init followed by the module name, which could be a project name or a URL of a repository. This action initializes a go.mod file, which keeps track of project dependencies and Go versions.

Q: What library did the author choose for building the REST API and why?

The author selected the Gin framework for creating the REST API due to its popularity and similarities to Express.js, which they were already familiar with. They appreciated how Gin simplifies handling HTTP requests and managing endpoints.

Q: What challenges did the author encounter during development?

The author faced issues with live reloading during development, finding that their Go application did not automatically restart upon file changes. They also shared difficulties in ensuring proper development tools were installed and set up, which caused frustration during coding.

Q: How did the author implement an in-memory key-value store in their API?

The author created a key-value map structure in Go to store values. They defined endpoints for both storing and retrieving values, using JSON format for input and output. This setup allowed users to interact with the API by storing and fetching information based on keys.

Q: What role did AI tools play in the author's development process?

The author utilized AI tools, specifically Cody AI, to assist with coding and problem-solving. They found AI helpful for learning new languages and libraries, although they occasionally struggled with AI suggestions not being accurate or relevant to their context.

Q: How did the author ensure their Go code was properly formatted?

The author attempted to set up auto-formatting in VS Code for Go files but encountered issues. They discussed configuring settings and installing necessary Go tools, indicating a desire for better development experiences similar to what they had with JavaScript and Node.js.

Q: What were the author's thoughts on the efficiency of Go compared to Node.js?

The author noted that the development experience in Go felt slower than Node.js, specifically mentioning longer reload times for their API during the coding process. They expressed a preference for the instant restarts they experienced with Node.js applications.
