Overrun NPM | npm.io

Overrun

Overrun is a framework for setting up asset processing pipelines in Node.js.

Features

Support for abitrary transformations of files.
Strongly-typed build definition files written in TypeScript.
Supports parallel build operations via promises.
Filesystem watch mode looks for source files that have changed and automatically rebuilds the targets that are out of date.
Promise-based API makes it easy to extend with arbitrary transformation steps.
Supports reduce() operations for combining multiple input files into a single output.

Differences from other task runners:

Overrun is similar in concept to tools such as Gulp, Grunt or Brunch, but it has a few differences. The primary use case for Overrun is processing 3D models and textures for games, but it can be used to convert other kinds of media as well.

There is no built-in functionality for generating JavaScript bundles or processing HTML, which most of these other tools have.
It is built around Promise/await functionality, as opposed to Node.js streams, making it easy to extend with new build rules.
Build files can be written in TypeScript, and all target and task definitions are strongly typed. This means that your editor's autocompletion can assist in writing build files.
