Bootstrapper

A lightweight Go package for managing application initialization order with dependency injection support.

Features

• Register components with custom initialization order
• Thread-safe shared state management
• Automatic lifecycle management (Booting/Booted phases)
• Predefined order constants for common components

Usage

Basic Registration

package main

type Database struct{}

func (d *Database) Booting() {
    // Initialize database connection
}

func (d *Database) Booted() {
    // Run migrations or post-init tasks
}

func main() {
    db := &Database{}
    bootstrapper.Register(db, bootstrapper.OrderDB)
    
    bootstrapper.StartBooting()
    bootstrapper.StartBooted()
}

Custom Order

const CustomOrder = 50

service := &MyService{}
bootstrapper.Register(service, CustomOrder)

Shared State

// Store shared data
bootstrapper.Share("config", myConfig)

// Retrieve shared data
config := bootstrapper.Get("config")

Predefined Orders

• OrderConfig (1) - Configuration
• OrderDB (2) - Database
• OrderCache (3) - Cache
• OrderQueue (4) - Queue
• WorkerPool (5) - Worker Pool
• OrderRepository (6) - Repository
• OrderService (7) - Service
• OrderController (8) - Controller

Testing

go test -v
