Blague: Static Site Generator
A bare-minimum static-site generator written in node, clocks in at 1 dependency and ~300 lines of not-particularly-efficient JS, rebuilds my entire blog in close to realtime.
There are a million better projects you should probably use instead, and if you want an actual CMS I can wholeheartedly recommend Ghost, but this is a personal exercise in “how much with how little.” Much of the software infrastructure we use is built around solving problems that the previous generation solved based on infrastructural issues that are now no-longer issues.
What can you do with just the basics? Quite a lot, actually.
