Yoga Layout for Go

Go Test

Go bindings for Facebook's Yoga Layout library - a cross-platform layout engine implementing Flexbox.

Features

  • 🎯 Complete Flexbox Implementation - Full support for CSS Flexbox properties
  • 📱 Cross-Platform - Works on all platforms supported by Go
  • 🔧 Simple API - Clean, idiomatic Go interface
  • 🎨 Layout Debugging - Built-in support for generating layout representations
  • ⚡ High Performance - Direct C bindings for optimal performance

Quick Start

package main

import (
    "fmt"
    "github.com/millken/yoga"
)

func main() {
    // Create a root node
    root := yoga.NewNode()
    defer root.Destroy()

    // Set flexbox properties
    root.SetWidth(375)
    root.SetHeight(667)
    root.SetFlexDirection(yoga.FlexDirectionColumn)

    // Create a child node
    child := yoga.NewNode()
    defer child.Destroy()
    child.SetFlexGrow(1)
    child.SetHeight(100)

    // Add child to parent
    root.InsertChild(child, 0)

    // Calculate layout
    root.CalculateLayout(yoga.Undefined, yoga.Undefined, yoga.DirectionLTR)

    // Print computed layout
    fmt.Printf("Child width: %.2f, height: %.2f\n",
        child.GetComputedWidth(), child.GetComputedHeight())

    // Generate layout representation for yogalayout.dev
    layout := root.ToYogaLayout()
    fmt.Println(layout)
}

Layout Debugging

The library provides built-in support for generating layout representations that can be used with yogalayout.dev playground:

root := yoga.NewNode()
defer root.Destroy()

root.SetWidth(200)
root.SetHeight(200)

child := yoga.NewNode()
defer child.Destroy()
child.SetFlexGrow(1)
child.SetHeight(100)

root.InsertChild(child, 0)
root.CalculateLayout(yoga.Undefined, yoga.Undefined, yoga.DirectionLTR)

layout := root.ToYogaLayout()
fmt.Println(layout)

Output:

<Layout config={{useWebDefaults: false}}>
    <Node style={{width: 200, height: 200}}>
    <Node style={{height: 100, flex: 1}} />
  </Node>
</Layout>
