Fathym Atomic Icons

Build, optimize, and consume SVG icon sprite sheets with ergonomic, typed icon components for Deno projects. Works standalone or alongside Fathym's Everything-as-Code (EaC) runtime.

Install

Add imports to your deno.json or deno.jsonc using JSR. Pin a version for stability.

{
  "imports": {
    "@fathym/atomic-icons": "jsr:@fathym/atomic-icons@^0.0.0",
    "@fathym/atomic-icons/browser": "jsr:@fathym/atomic-icons/browser@^0.0.0"
  }
}

Naming Icons

Prefer semantic names decoupled from the upstream set (e.g., map material-symbols:check-circle to check-circle) to keep usage consistent and swaps painless.

Quick Start

1. Create a config describing your icon set and generation options.

// ./fathym-atomic-icons.config.ts
import { IconSetConfig, IconSetGenerateConfig } from "@fathym/atomic-icons";

export const curIconSetConfig: IconSetConfig = {
  IconMap: {
    "x-circle": "https://api.iconify.design/bi:x-circle.svg",
    "check-circle":
      "https://api.iconify.design/material-symbols:check-circle.svg",
    "exclaim": "https://api.iconify.design/bi:exclamation-circle.svg",
  },
  Optimize: true,
};

export const curIconSetGenerateConfig: IconSetGenerateConfig = {
  Exports: true,
  IconSet: curIconSetConfig,
  SpriteSheet: "/iconset/icons",
};

2. Generate assets via a script and Deno task.

// ./scripts/icons.atomic.ts
import { useFileIconSet, useIconSetComponents } from "@fathym/atomic-icons";
import {
  curIconSetConfig,
  curIconSetGenerateConfig,
} from "../fathym-atomic-icons.config.ts";

await useFileIconSet("./static/icons.sprite.svg", curIconSetConfig);
await useIconSetComponents(curIconSetGenerateConfig, "");

{
  "tasks": {
    "icons": "deno run -A ./scripts/icons.atomic.ts"
  }
}

Run: deno task icons. Add build/ to .gitignore.

3. Use your icons.

import { Icon } from "@fathym/atomic-icons/browser";

export default function Page() {
  return (
    <>
      <Icon src="/iconset/icons" icon="x-circle" />
      <Icon
        src="/iconset/icons"
        icon="check-circle"
        class="text-blue-500 w-[50px] h-[50px]"
      />
    </>
  );
}

import {
  CheckCircleIcon,
  ExclaimIcon,
  XCircleIcon,
} from "$fathym/atomic-icons";

export default function Page() {
  return (
    <>
      <XCircleIcon />
      <CheckCircleIcon class="text-purple-500 w-[50px] h-[50px]" />
      <ExclaimIcon class="text-purple-500 w-[24px] h-[24px]" />
    </>
  );
}

When Exports is true, useIconSetComponents writes an import alias:

{
  "imports": {
    "$fathym/atomic-icons": "./build/iconset/icons/.exports.ts"
  }
}

Serving the Sprite Sheet

Place the generated sheet where your server can serve it (e.g., /static/icons.sprite.svg) and point SpriteSheet to that path. Generated components expect the sheet URL you provide.

Development Tasks

• Format/lint/check: deno fmt, deno lint, deno check.
• Tests: deno task test.
• Build: deno task build (fmt + lint + publish check + tests).
• Tailwind config generation: deno task build:tailwind.
• Publish flows: deno task publish:check, deno task npm:build/publish.

Notes

• Keep semantic icon naming and document any licensed/external sets you map.
• Maintain examples in this README aligned with current exports in mod.ts, browser.ts, and generator behavior.
