Air
Air is a live reload tool and build automation utility for Go applications. It functions as a hot reloading orchestrator that monitors source files for changes to automatically recompile and restart application binaries.
The tool distinguishes itself by offering a managed build and execution pipeline, allowing for custom build commands, environment variable injection, and platform-specific build overrides based on the host operating system. It further synchronizes the development cycle by using a proxy to signal web browsers to reload automatically when static files or source code are modified.
The project covers a broader surface of development automation, including file system watcher filtering to optimize performance and process lifecycle management to handle the replacement of stale binaries.
Features
- Live Reloading Environments - Provides a development environment that monitors Go source changes and automatically restarts the application process.
- Build Pipeline Customization - Allows developers to define custom build commands, execution arguments, and environment file loading.
- File System Watchers - Acts as a background process that monitors directory trees for changes to trigger build scripts.
- Hot-Reloading Systems - Enables an iterative development cycle where changes are reflected immediately without manual restarts.
- Live Reloading Tools - Monitors Go source files for changes and automatically restarts the application binary for rapid iteration.
- Process Lifecycle Managers - Manages the lifecycle of application binaries by killing stale processes and spawning new instances after recompilation.
- Binary Restarts - Automatically triggers recompilation and binary restarts for a continuous development workflow.
- Go Environments - Provides automated compilation and execution support tailored for Go programming environments.
- Build Automation - Streamlines the Go compilation process through environment variables and OS-specific build overrides.
- File System Monitors - Implements real-time monitoring of the file system to trigger application restarts upon source code changes.
- Browser Reload Triggers - Air signals a web browser to reload automatically when static files are modified via a proxy configuration.
- File Watcher Configurations - Provides inclusion and exclusion rules for directories to optimize file system watcher performance.
- Shell Command Execution - Provides the ability to invoke and capture output from shell commands to orchestrate build and run sequences.
- Platform-Specific Resolution Strategies - Automatically selects different build arguments and binaries based on the detected host operating system.
- Environment Variable Configurations - Injects key-value pairs from local configuration files into the child process environment before execution.
- Developer Feedback Loops - Shortens the feedback loop by automatically updating backend services and refreshing browsers upon modification.
- Live-Reload Proxies - Uses a local network proxy to intercept requests and signal web browsers to reload automatically.
- Build and Compilation Tools - Live-reload tool for development.
- Build Automation - Live reload tool for Go applications.
