Writing maintainable code is essential. Clarity, readability, and simplicity are all aspects of maintainability. It should make the process easy for someone to join your project or maintain it after someone leaves. Maintainability is measured by how effortless it is to introduce changes and the amount of risk associated with those changes. To write Go effectively, it is crucial to understand its properties and idioms and apply the established conventions related to naming, program construction, formatting, etc.

Great video on Delve & Go, Delve is a popular feature-rich debugger for Go. 22 minutes

Goapp is an opinionated guideline to structure a Go web application/service (or could be extended for any application). These opinions were formed over a span of 5+ years building web applications/services with Go, trying to implement DDD (Domain Driven Development) & Clean Architecture. Even though I've mentioned go.mod and go.sum, this guideline works for 1.4+ (i.e. since introduction of the special 'internal' directory).

Tant que Go est encore en version 1.15.x et n'a pas encore les embeds de fichier en standard, voici comment utiliser pkger pour embarquer vos templates ou tout autre asset:

While Go is still 1.15.x and doesn't yet have standard embeds, here is how to embed templates (or whatever assets you need) in your code with pkger.

As a Golang developer, you probably have encountered import cycles. Golang do not allow import cycles. Go throws a compile-time error if it detects the import cycle in code. In this post, let’s understand how the import cycle occurs and how you can deal with them.

This is the next installment of our series by Ayooluwa Isaiah that explains features in Go so developers can compare them to Ruby or whatever other language.

In the previous article in this series, we had an extensive discussion on the Go net/http package and how it can be used for production-ready web applications. We focused mostly on the routing aspect and other quirks and features of the http.ServeMux type.

This article will close out the discussion on ServeMux by demonstrating how middleware functions can be implemented with the default router and introducing other standard library packages that are sure to come in handy when developing web services with Go. https://www.honeybadger.io/blog/ruby-to-go-4/

Random fake data and struct generator for Go.

https://github.com/pioz/faker

• More than 100 generator functions
• Struct generator
• Unique data generator
• Builtin types support
• Easily customizable
• Zero dependencies
• Recursive infinite loop detector
• Benchmarks (coming soon)

Struct Builder Example

faker.SetSeed(622)

// Define a new builder
colorBuilder := func(params ...string) (interface{}, error) {
  return faker.Pick("Red", "Yellow", "Blue", "Black", "White"), nil
}

// Register a new builder named "color" for string type
err := faker.RegisterBuilder("color", "string", colorBuilder)
if err != nil {
  panic(err)
}

type Animal struct {
  Name  string `faker:"username"`
  Color string `faker:"color"` // Use custom color builder
}

type Person struct {
  FirstName string            `faker:"firstName"`         // Any available function case insensitive
  LastName  *string           `faker:"lastName"`          // Pointer are also supported
  Age       int               `faker:"intinrange(0,120)"` // Can call with parameters
  UUID      string            `faker:"uuid;unique"`       // Guarantees a unique value
  Number    int               `faker:"-"`                 // Skip this field
  Code      string            // No tag to use default builder for this field type
  Pet       Animal            // Recursively fill this struct
  Nicknames []string          `faker:"username;len=3"`          // Build an array of size 3 using faker.Username function
  Extra     map[string]string `faker:"stringWithSize(3);len=2"` // map are supported
}

p := Person{}
err = faker.Build(&p)
if err != nil {
  panic(err)
}
fmt.Println(p.FirstName)
fmt.Println(*p.LastName)
fmt.Println(p.Age)
fmt.Println(p.UUID)
fmt.Println(p.Number)
fmt.Println(p.Code)
fmt.Println(p.Pet.Name)
fmt.Println(p.Pet.Color)
fmt.Println(len(p.Nicknames))
fmt.Println(p.Nicknames[0])
fmt.Println(p.Nicknames[1])
fmt.Println(p.Nicknames[2])
fmt.Println(p.Extra)
// Output: Wilber
// Gutkowski
// 25
// ff8d6917-b920-46e6-b1be-dc2d48becfcb
// 0
// z
// honegger
// Red
// 3
// teagan
// polypeptide
// chinfest
// map[70w:3F6 gQS:isq]

Factory

One of the nice things about Faker is that it can also be used as a factory library. In fact when we call the faker.Build function if a value is not zero then it is not modified, leaving the original value. This allows you to create factory functions very easily:

faker.SetSeed(623)

type User struct {
    Username string `faker:"username"`
    Email    string `faker:"email"`
    Country  string `faker:"CountryAlpha2"`
}

italianUserFactory := func() *User {
    u := &User{Country: "IT"}
    faker.Build(u)
    return u
}

italianUser := italianUserFactory()
fmt.Println(italianUser)
// Output: &{spicule hoag@ornamented.biz IT}

When you're deciding on a technology to use for your project, it helps to have a broad understanding of your options. You may be tempted to build a web service in Go for performance reasons - but what would that code actually look like? How would it compare to languages like Ruby or JS? In this article, Ayooluwa Isaiah gives us a guided tour through the building blocks of go web services so you'll be well-informed. https://www.honeybadger.io/blog/go-web-services/

When you're evaluating a language for your next project, few things are more important than available third-party libraries and the package manager that ties them together. While early versions of Go lacked a package manager, they've made up for lost time. In this article, Ayooluwa Isaiah introduces us to Go's module ecosystem to help us decide if Go is "a go" for our next project. https://www.honeybadger.io/blog/golang-go-package-management/

These days fewer and fewer web developers get to specialize in a single language like Ruby. We use different tools for different jobs. In this article, Ayooluwa Isaiah argues that Go is the perfect complement to Ruby. The developer who knows both is in a great position to handle almost any back-end challenge. https://www.honeybadger.io/blog/rubyist-learn-go/

Go has built-in features to make it easier for programmers to implement logging. Third parties have also built additional tools to make logging easier. What's the difference between them? Which should you choose? In this article Ayooluwa Isaiah describes both of these and discusses when you'd prefer one over the other. https://www.honeybadger.io/blog/golang-logging/

In this post, I will talk about a very important feature in the complex projects we work with daily: metrics. Among the various solutions on the market for this purpose, one that has gained more prominence is the duo Prometheus + Grafana.

Hello Everyone!

Thank you for contributing to Golangflow.io, all the amazing content. Over the next few weeks, I will be migrating this site to Google Cloud Run in GCP and deploying a few new features. Hopefully, you won't notice the migration :)
