🧩 Terraform Provider - ValidateFX

Reusable validation functions for Terraform, built with the latest Terraform Plugin Framework.

ValidateFX lets you write cleaner, more expressive validations using functions like email, uuid, base64, and more. Use the assert function to validate conditions with custom error messages.

🚀 Example

terraform {
  required_providers {
    validatefx = {
      source  = "The-DevOps-Daily/validatefx"
      version = "0.1.0"
    }
  }
}

provider "validatefx" {}

variable "email" {
  type = string
}

locals {
  # Validate email with custom error message
  email_check = provider::validatefx::assert(
    provider::validatefx::email(var.email),
    "Invalid email address provided!"
  )

  # Or use in variable validation
  age_validation = provider::validatefx::assert(
    var.user_age >= 18,
    "User must be at least 18 years old!"
  )
}
