Environment configuration loading for NestForge
Documentation

nestforge-config

A NestJS-inspired configuration module for NestForge applications.

Features

  • Type-safe configuration - Get typed values from environment variables
  • NestJS-like API - Familiar patterns for NestJS developers
  • DI Integration - Seamlessly works with NestForge's dependency injection
  • Simple getters - No unwrap_or chains, just get_string_or("KEY", "default")
  • Dotenv support - Automatic loading from .env files

Quick Start

use nestforge_config::{ConfigService, ConfigModule};

pub type AppConfig = ConfigService;

pub fn load_config() -> AppConfig {
    ConfigModule::for_root_with_options(ConfigModule::for_root().env_file(".env"))
}

Usage in Services

use nestforge::prelude::*;

pub struct MyService {
    config: Config<AppConfig>,
}

impl MyService {
    pub fn do_something(&self) {
        let app_name = self.config.get_string_or("APP_NAME", "My App");
        let port = self.config.get_u16_or("PORT", 3000);
        let debug = self.config.get_bool_or("DEBUG", false);
    }
}
