Forever
Forever is a process manager and command-line utility designed to run scripts continuously. It functions as a process watchdog that monitors background tasks and automatically restarts them upon failure to ensure continuous operation.
The system provides a log streaming tool to capture and monitor the standard output and error streams of managed scripts in real time. It also includes development hot reloading, which triggers a process restart whenever modifications are detected in source files or specified directories.
The tool covers a broad range of orchestration capabilities, including process lifecycle control, status monitoring, and the use of structured configuration files to define startup parameters. It also maintains system hygiene through the cleanup of orphaned logs and stale process identification files.
Features
- Background Process Orchestration - Provides comprehensive orchestration for starting, stopping, and monitoring multiple long-running background scripts.
- Process Lifecycle Managers - Provides a comprehensive system for starting, stopping, and monitoring background tasks using unique process identifiers.
- CLI Process Controls - Provides a command-line interface for the continuous execution and automatic recovery of background scripts.
- Stream Redirection Tools - Captures standard output and error streams from managed processes and redirects them into persistent log files.
- Watchdog Monitors - Monitors background processes and triggers automatic restarts upon failure or source file changes.
- Process Lifecycle Managers - Manages the execution state of scripts by tracking whether they are running, stopped, or have crashed.
- Child Process Execution - Provides the capability to spawn scripts as independent system processes and monitor their exit codes for automatic restarts.
- Automatic Crash Recovery - Ensures high availability by automatically restarting applications immediately after an unexpected crash.
- JSON-Configured Process Managers - Functions as a process manager that uses structured JSON files to define application startup and environment parameters.
- Log Streaming - Captures and tails real-time standard output and error streams from managed background scripts.
- JSON-Based Startup Mapping - Uses structured JSON files to map application names to their respective startup commands and environment settings.
- File Watchers - Provides a file watcher that triggers automatic process restarts when source files are modified.
- Hot-Reloading Systems - Automatically restarts running scripts when source file modifications are detected to improve development speed.
- JSON Configuration Schemas - Defines startup options and environment settings using structured JSON configuration files.
- Application Configuration - Allows starting multiple applications using a configuration file to define operational parameters.
- File System Monitors - Monitors source directories for timestamp changes to automatically trigger process restarts.
- PID-Based Process Tracking - Maintains process state across restarts by storing process identifiers in dedicated filesystem directories.
- Process Monitors - Retrieves metadata and current state information to monitor the status of all active managed processes.
- Log Stream Monitors - Streams and captures the output of background processes for real-time troubleshooting and activity monitoring.
- Process Management - Keeps scripts running continuously.
