Building Microservices API in Go - banking-lib Module in Banking API

In this video, the instructor demonstrates how to extract error and logger components from a banking project and create a separate Go module. The process includes adding a missing ZAP dependency, bumping the module version, and releasing a new version with a tag. The video also covers integrating the banking library into the project, resolving errors, and refactoring code. The importance of testing and maintaining good test coverage is emphasized. The video concludes with a preview of the next video, which will focus on similar tasks for the Auth API.

What was the initial step taken to resolve the missing ZAP dependency in the Go module?

• Adding the ZAP dependency using 'go get'

• Ignoring the error

• Rewriting the entire module

• Removing the logger

What version number was assigned to the updated Go module after changes?

• 1.0.0

• 1.0.1

• 2.0.0

• 1.1.0

What is the first step to integrate the updated Go module into the banking API?

• Delete the entire API

• Add the banking Lib as a Go module

• Revert to the previous version

• Ignore the missing folders

How can you ensure the latest version of a Go module is used despite proxy delays?

• Wait indefinitely

• Append the version number to the module name

• Use a different programming language

• Restart the computer

What method is suggested for replacing module references across multiple files?

• Ignore the errors

• Delete all files

• Use a find and replace tool

• Manually edit each file

What command is used to verify that the project builds without errors after changes?

• go run

• go test

• go build

• go clean

Why is having a good test coverage important during refactoring?

• It makes the code run faster

• It eliminates the need for documentation

• It provides confidence that changes haven't broken existing functionality

• It reduces the size of the codebase
