What is this?
Grunt is a JavaScript task runner: you describe your project's repetitive tasks once, and Grunt executes them for you so you don't run each step by hand.
So is this a command-line tool or a library I code against?
Both, in a sense: it's an npm package you add to a project, and its companion grunt-cli dependency gives you the 'grunt' command to run it from the terminal. It runs on Node.js, 16 or newer.
How do I get it into a project and start using it?
Install it from npm in your project (the package plus the grunt-cli companion), and turn to the gruntjs.com website for docs - the README sends you there 'for all the things'.
What does my machine need before I can run it?
Node.js 16 or newer is the declared requirement. The dependency list is pure JavaScript (glob, minimatch, js-yaml and friends), so there's no native build step or extra service to run.
Old Grunt versions are everywhere - which ones are actually maintained?
Only the latest version (1.6) still receives security and bug fixes. Version 1.5 and everything older is end-of-life; HeroDevs sells commercial drop-in replacements for those.
The repo dates back to 2011 - is Grunt still alive?
Yes: it's not archived, CI runs a test workflow on changes, the 1.6 line is supported, and it sits in the OpenJS ecosystem's sustainability program with a commercial partner.
Will it run on my machine - Windows, macOS, Linux?
Anywhere Node runs: it's a plain Node package with a cross-platform CLI, so Windows, macOS and Linux all work.
What if my project is stuck on an old Grunt version?
HeroDevs, the project's partner in the OpenJS Ecosystem Sustainability Program, provides drop-in replacements for older Grunt releases (down to 0.4) that are kept up to date for security and compliance.
What kind of tasks would I automate with it?
The repetitive chores of a JS project - linting, testing, building - become automated steps instead of commands you retype. This repo itself keeps that flow: its CI lints with ESLint and runs QUnit unit tests.
Which topics is it in?
build-automation, pipelines, linting, task, devtools, build-tool, cli-tool, hacktoberfest, npm, automation, tool, nodejs
