I like diagrams that live close to the code they explain. An exported image is easy to forget, difficult to review, and usually out of date after a few changes.
That is why I built @schemd/core, a zero-dependency compiler that turns a small text format into accessible SVG.
Schemd currently handles common circuit components, classical and quantum gates, configurable ICs, and the UML diagrams I use most often: class, sequence, state, and use-case diagrams. It runs on the server or during a build, so the browser does not need the compiler or a Markdown package.
A quick example
Install the package:
