I’m here today to talk about Pocketbase!, an Opensource back-end that is distributed in a single Go binary. More in the docs page…

You heard me right, a single file. The magic behind this project is Go, compiled and built to use SQLite as it’s database with a REST-ish API that packs a whole set of features. At the time of writing, a Javascript SDK exists to easily add on top with Svelte, React or what ever other front-end framework you like to use.

Real time database (Powered by SQLite)
File Storage — Integrates with S3, more Object Storage support is coming.
Authentication
Full Featured Admin UI — To manage users, collections & more
Extendable via Go Programming Language to extend functionality

This is great for a Micro-SaaS, Mobile back-end or even your next hobby project. Coupled with something such as Litestream by Ben Johnson for SQLite replication for real-time backups and FlyIO for Hosting can really be your goto stack.

Several Docker images are being built, even mine and hopefully soon an Official Docker Image.

In my next post, I’ll walk through how to setup Pocketbase with a Simple front-end using Fly hosting.

Thanks for Reading!

config is an easy-to-use package that supports reading configuration into a struct from files, environment variables and command-line arguments. All you need is to declare a structure that will hold your configuration and call Read method. The library will pool the values from a config file in any well-known format, from env vars that follows simple naming convention, or from command-line arguments

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.

On the Martian blog, Svyatoslav Kryukov enters into a fantasy realm, and is forced to imagine that ✨everything must be written in Go!✨

Read and learn to write Go in Ruby, gaining the ability to modify Ruby exactly as you desire.

In this article, he covers:

• Replicating Go’s functionality in Ruby.
• Modifying a lexer and parser – then creating your own!
• Adding a rewriter with the help of Ruby Next.
• Plus, other cool techniques to bring everything to life!

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 [email protected] IT}
