Validation with Fiber

This example demonstrates how to use go-playground/validator for input validation in a Go Fiber application.

Description

This project provides a basic setup for validating request data in a Go Fiber application using the go-playground/validator package. It includes the necessary configuration and code to perform validation on incoming requests.

Requirements

• Go 1.18 or higher
• Git

Project Structure

• main.go: The main application entry point.
• config/env.go: Configuration file for environment variables.
• go.mod: The Go module file.
• .env: Environment variables file.

Setup

1. Clone the repository:

   git clone https://github.com/gofiber/recipes.git
   cd recipes/validation

2. Install the dependencies:

   go mod download

3. Create a .env file in the root directory with the following content:

   PORT=":8080"

4. Run the application:

   go run main.go

The application should now be running on http://localhost:8080.

Example Usage

1. Send a POST request to http://localhost:8080/validate with a JSON payload:

   {
       "name": "John Doe",
       "email": "[email protected]",
       "age": 30
   }

2. The server will validate the request data and respond with a success message if the data is valid, or an error message if the data is invalid.

Code Overview

main.go

The main Go file sets up the Fiber application, handles HTTP requests, and performs validation using the go-playground/validator package.

config/env.go

The configuration file for loading environment variables.

package config

import "os"

// Config func to get env value
func Config(key string) string {
    return os.Getenv(key)
}

Conclusion

This example provides a basic setup for validating request data in a Go Fiber application using the go-playground/validator package. It can be extended and customized further to fit the needs of more complex applications.
