How to install Gubrak in a Go project?

Use 'go get -u github.com/novalagung/gubrak/v2' as per the installation instructions in the README. This command fetches the latest version and integrates it into your Go modules setup seamlessly.

Gubrak vs lo: which utility library is better for Go?

Gubrak offers a lodash-like API with comprehensive collection functions, ideal for developers familiar with JavaScript utilities. In contrast, lo is more minimalistic and performance-focused, so choose based on expressiveness vs. lightweight needs.

What are the main functions for working with maps in Gubrak?

Gubrak provides functions like GroupBy, KeyBy, and FromPairs for map operations, allowing efficient data grouping and transformation as listed in the API section of the README.

Is Gubrak compatible with Go generics?

Gubrak v2 is built for modern Go, but the README doesn't explicitly mention generics support. Check the pkg.dev documentation for type-specific implementations and ensure it aligns with your Go version.

How to filter a slice using Gubrak in Go?

Use the Filter function with a predicate callback, such as 'result := gubrak.Filter(slice, func(item interface{}) bool { return condition })'. This mirrors lodash-style syntax for concise data filtering.

Does Gubrak support concurrent data processing?

While it includes functions like Each, Gubrak doesn't explicitly offer concurrency primitives. For concurrent operations, you may need to manually integrate it with Go's goroutines and channels.

What changed in Gubrak v2 compared to v1?

The README doesn't detail migration changes; refer to release notes or pkg.dev for breaking updates. V2 likely improves API stability and adds new features, but documentation is minimal on specifics.

What is gubrak?

Gubrak is a functional utility library for Go that provides lodash-like helper functions for common data manipulation tasks. It offers syntactic sugar for working with collections, performing type checks, and implementing functional programming patterns in Go applications. The library helps developers write more expressive and concise code while maintaining Go's performance characteristics.

Target Audience

Go developers who need efficient collection operations and functional programming utilities, particularly those familiar with lodash from JavaScript/TypeScript ecosystems.

Value Proposition

Developers choose Gubrak because it brings the convenience and expressiveness of lodash to Go with a comprehensive API covering collection operations, type checking, and data transformation. It reduces boilerplate code while maintaining Go's static typing and performance benefits.

Overview

⚙️ Golang functional utility library with syntactic sugar. It's like lodash, but for Go

Use Cases

Best For

Manipulating slices and maps with functional operations like map/filter/reduce
Performing type checking and validation on Go data structures
Implementing lodash-style utilities in Go applications
Reducing boilerplate code for common data transformation tasks
Adding syntactic sugar to make Go code more expressive
Working with collections in a functional programming style

Not Ideal For

Applications that prioritize minimal external dependencies and strict adherence to Go's standard library
Projects where micro-optimizations for collection operations are critical and hand-written loops are preferred
Teams seeking a utility library with extensive community support, frequent updates, and a large ecosystem

Pros & Cons

Pros

Comprehensive Collection Utilities

Offers a wide range of functions like Filter, Map, Reduce, and GroupBy from the README's API list, enabling expressive data manipulation on slices and maps.

Functional Programming Patterns

Supports composable operations and immutable transformations, making it easier to implement lodash-like functional styles in Go, as highlighted in the key features.

Type Checking and Validation

Includes predicates such as IsArray, IsString, and IsInt for robust data validation, reducing boilerplate code for type-safe operations in Go.

Syntactic Sugar for Common Tasks

Provides helper functions like RandomString, Now, and Chunk listed in the README, enhancing code readability and reducing repetitive coding efforts.

Cons

Sparse Inline Documentation

The README lacks practical examples and tutorials, only listing APIs and linking to pkg.dev, which may increase initial learning time and require external resources.

Potential Performance Overhead

As an abstraction layer, functions like Map and Filter might introduce slight overhead compared to optimized native loops, though not benchmarked or addressed in the documentation.

Limited Community and Ecosystem

With fewer GitHub stars and less visibility than alternatives like lo, Gubrak has a smaller user base, which can mean slower updates and fewer third-party integrations.

Open Source Alternative To

gubrak is an open-source alternative to the following products:

Lodash

Lodash is a popular JavaScript utility library that provides consistent, modular functions for common programming tasks like array manipulation, object iteration, and function composition.
