🐹 flaggo-go

Go SDK for Flaggo - The minimalist, zero-config feature flag library.

📦 Installation

go get github.com/FabienOnnis/flaggo/flaggo-go

🚀 Quick Start

package main

import (
	"fmt"
	"github.com/FabienOnnis/flaggo/flaggo-go"
)

func main() {
	flags, err := flaggo.Load(flaggo.FlaggoOptions{
		Source:  "https://config.example.com/flags.json",
		Context: flaggo.FlagContext{"userId": "user-123", "role": "admin"},
	})
	if err != nil {
		panic(err)
	}

	// Advanced Rules targeting
	if flags.IsEnabled("admin-feature", nil) {
		fmt.Println("Admin feature is active!")
	}
}

✨ Key Features

• 🎯 Zero-config: Just a JSON file.
• ⚡ High Performance: Low-allocation rule engine (~55ns/op).
• 🎯 Advanced Targeting: Support for custom rules (role, email, plan) with operators like ==, in, matches (Regex).
• 🔗 Cross-Language Consistency: Decisions stay identical across all SDKs (using FNV-1a).
• 🛡️ Environment-aware: Easily filter flags by environment.
