Features

• Development Trigger Automations - Automates development workflows by watching file changes and lock files to trigger only necessary scripts.
• Build Orchestrators - Functions as a build orchestrator that tracks input files and dependencies to optimize total build time.
• Cache Input and Output Specifications - Uses rules to determine result validity based on file and environment state, restoring output files from previous runs.
• NPM Script Runners - Provides a system for defining and executing scripts defined in package configuration files with strict dependency management.
• Parallel Task Execution - Executes independent scripts simultaneously based on system capacity and dependency graphs to reduce processing time.
• Script Dependency Managers - Establishes strict execution sequences to ensure all necessary prerequisites run before dependent tasks start.
• Task Dependency Management - Allows defining scripts as prerequisites for other tasks to establish a strict execution order.
• Content-Addressable Caches - Implements a content-addressable cache that uses input hashing to skip redundant build computations.
• Build Pipeline Optimization - Reduces build times by skipping unchanged tasks and running independent scripts in parallel using a dependency graph.
• File-Change-Triggered Restarts - Automatically triggers the execution of affected scripts in the task graph when monitored files are modified.
• Input-State Skipping - Skips running a script if its input files and configuration match the state of the last successful run.
• Hash-Based Change Detection - Uses cryptographic hashes of input files and environment variables to detect changes and determine if tasks need re-execution.
• Directed Acyclic Graph Pipelines - Orchestrates script execution by building a directed acyclic graph to manage dependencies and maximize parallelism.
• File System Monitors - Monitors the filesystem for changes to automatically trigger the re-execution of affected tasks in the dependency graph.
• Background Service Management - Orchestrates persistent background processes that start and stop automatically with their dependent build tasks.
• Frontend Build Tools - Manages output artifacts and caching for web-based assets to avoid redundant computations during development.
• Dependency Cascade Controls - Prevents dependent tasks from triggering if a prerequisite script completes without producing new output files.
• Environment Variable Management - Manages environment variables to influence script fingerprints and control caching behavior.
• Resource-Aware Parallelization - Limits simultaneous process spawns based on available CPU cores to prevent system resource exhaustion.
• Dependency Lock Files - Monitors package manager lock files to trigger script re-runs when project dependencies are updated.
• Failure Handling Policies - Controls whether to terminate the entire process or continue execution when a script returns a non-zero exit code.
• Output-Based Execution Controls - Prevents dependent tasks from triggering if a prerequisite script completes without producing new output files.
• Background Process Orchestration - Manages persistent background scripts as services that remain active throughout the build process.
• Concurrency Limiters - Caps the number of simultaneous scripts based on available CPU cores to prevent system resource exhaustion.
