Error Handler Library
Introduction
The Error Handler Library provides a centralized solution for managing errors in Go applications. Its primary purpose is to streamline error handling across various frameworks, ensuring that developers can focus on building features rather than managing error states.
🚀 Features
- Centralized error handling
- Automatic database error detection
- Panic recovery
📦 Installation
go get github.com/emreisler/error-handler
🛠 Usage Examples
Gin Middleware
import "github.com/emreisler/error-handler"
func main() {
r := gin.Default()
r.Use(error_handler.GinMiddleware())
// Your routes here
}
net/http Middleware
import "github.com/emreisler/error-handler"
func main() {
http.Handle("/", error_handler.NetHTTPMiddleware(http.HandlerFunc(yourHandler)))
http.ListenAndServe(":8080", nil)
}
Chi Middleware
import "github.com/emreisler/error-handler"
func main() {
r := chi.NewRouter()
r.Use(error_handler.ChiMiddleware())
// Your routes here
}
Fiber Middleware
import "github.com/emreisler/error-handler"
func main() {
app := fiber.New()
app.Use(error_handler.FiberMiddleware())
// Your routes here
}
🔗 Database Error Handling
The mapDBError function automatically maps database errors to a standardized error type, allowing for consistent error responses.
⚠️ Panic Recovery
The library includes built-in panic recovery to prevent application crashes due to unexpected errors.
📌 Error Type Mapping
The library provides a mechanism for mapping different error types to a unified structure, making it easier to handle errors across various components.
