Godotenv
godotenv is a Go library designed to load, parse, and serialize environment configuration files. It provides tools to extract configuration data from files into maps and inject those key-value pairs directly into the system environment of a Go application process.
The project includes a configuration file serializer for exporting environment variable maps back into formatted files and a parser for extracting data without modifying the system environment. It supports injecting variables from strings or files into the process environment using priority-based overloading and overwriting.
The library covers general environment variable management and application configuration, including utilities for secret management workflows and local development setup. It also provides capabilities for shell command wrapping to execute external processes with a merged set of environment variables.
Features
- Environment Variable Loaders - Provides a library for loading environment variables from .env files into a Go application process.
- Environment Variable Management - Provides a comprehensive system for loading, injecting, and managing runtime environment variables as a primary configuration source.
- Property File Parsers - Extracts configuration data from .env files into maps without modifying the system environment.
- Environment Variable Loaders - Provides a tool for injecting key-value configuration pairs from files or strings into the system environment.
- External Environment File Loaders - Provides utilities to serialize configuration pairs into formatted files or strings for storage.
- Environment Configuration - Extracts configuration pairs from various sources into a map without altering the system environment.
- Process Injection Wrappers - Updates the current operating system process environment using system calls to make variables available to child processes.
- Configuration Tooling - Manages application settings in Go by separating environment-specific variables from the main codebase.
- Environment Variable Managers - Allows replacing existing system environment variables with new values defined inside a configuration file.
- Environment Variables - Injects key-value pairs from files or strings into the system environment using priority-based overloading.
- Environment Variable-Based Configuration - Implements priority-based overloading to determine which value wins when variables exist in both system and config files.
- Configuration File Parsers - Implements a scanner to extract key-value configuration data from raw text strings or files.
- Development Environment Setups - Facilitates consistent local development by sharing configuration files that define necessary system variables.
- Environment File Exporters - Provides a utility for writing a map of environment variables to a formatted and escaped file.
- Parametrized Command Execution - Provides a utility to load variables from a file into the process environment before executing a shell command.
- Shell Command Runners - Executes external processes by merging custom environment variables with the existing system environment.
- Secret Management - Supports secret management workflows by loading sensitive keys from external files into the process environment at runtime.
- Serializers - Implements a utility for writing and exporting environment variable maps back into formatted .env files.
- Environment File Serialization - Provides a serializer to export environment variable maps back into formatted .env files.
- Configuration Management - Loads environment variables from .env files.
- Configuration Management - Listed in the “Configuration Management” section of the Awesome Go awesome list.
