Used along with @warp-ds/elements-core this ESBuild plugin lets you get a minimal set of UnoCSS utility CSS classes for your WarpElement.styles property.

npm install @warp-ds/esbuild-plugin

// build.js

import * as esbuild from "esbuild";
import * as eik from "@eik/esbuild-plugin";
import warpPlugin from "@warp-ds/esbuild-plugin";

	logLevel: "info", // Adjust this if you get problems
	bundle: true,
	platform: "browser",
	sourcemap: true,
	plugins: [
