When I say “testable code”, what I mean is code that can be easily programmatically verified. We can say that code is testable when we don’t have to change the code itself when we’re adding a unit test to it.

API clients are very helpful when you’re shipping your REST APIs to the public. And Go makes it easy, for you as a developer, as well as for your users, thanks to its idiomatic design and type system.

You may ask why doing this if we can use PersistentVolume? Though there may be multiple scenarios when mounting GCS bucket to you Kubernetes Pod is a good option:

If you are running HTTP server and want to rate limit requests to the endpoints, you can use well-maintained tools such as github.com/didip/tollbooth. But if you’re building something very simple, it’s not that hard to implement it on your own.

This post is a text version of packagemain #6: Building Desktop App in Go using Wails video. As we all know, Go is mostly used to build APIs, web backends, CLI tools.

Applications with database layer mostly need to execute database migration as part of its deployment process. Usually, running migrations is the first step when deploying the application.

Earlier this month Google Cloud Functions team finally announced beta support of Go, the runtime uses Go 1.11, which includes go modules as we know.

Seems like ClickHouse is experiencing growth in industries like IoT, Web Analytics, AdTech, Log Management, because of its robustness with big amounts of data. IMO it’s a great tool but missing developer community support.

In practice-go we often use table driven testing to be able to test all function scenarios. For example the FindAnagrams() function returns us a list of anagrams found in the dictionary for given input.
