Gear.js

Task-Based Build System

Gear.js is a scriptable build system using simple tasks that act like a sequence of piped commands.

Features include:

• Basic building blocks that can be combined to perform complex builds.
• Tasks are simply defined and keep system internals to a minimum.
• Asynchronous execution.
• Extensible task loading via NPM, file, or directory.
• Advanced flow control for complex task execution.
