@fibrae/semi-icons-core

简体中文

Framework-agnostic icon and illustration data, plus icon styles, for Semi Design Next. The icon packages (semi-icons-<framework>, illustrations included) of every framework read this data. You can also use it directly to render icons yourself.

Installation

pnpm add @fibrae/semi-icons-core

Ships ESM only, with no peer dependencies.

Usage

Each icon is an ESM module that exports IconData, under the same name as the icon component in each framework:

import { IconActivity } from '@fibrae/semi-icons-core';
import { IconAvatar } from '@fibrae/semi-icons-core/lab'; // color icon that keeps its original colors

IconActivity;
// {
//     name: 'activity', // icon type, rendered as the `semi-icon-activity` class
//     attrs: { viewBox: '0 0 24 24', fill: 'none', xmlns: 'http://www.w3.org/2000/svg' },
//     children: [['path', { 'fill-rule': 'evenodd', 'clip-rule': 'evenodd', d: '...', fill: 'currentColor' }]],
// }

• A node is [tag, attrs, children?]. Attribute names are DOM names (fill-rule, class, with style as a string), so a framework can pass them through as they are or map them once (React uses fillRule, className and a style object).
• When rendering, add defaultAttrs to the root svg: width and height of 1em, focusable="false", aria-hidden="true".
• Multi-color icons (IconAI*Level2, IconAI*Level3, IconAILoading) carry fills, the number of colors supplied through the fill prop. Attribute values contain placeholders: {fillN} is the Nth color of getFillColor(fill, fills), and {uid} is an id unique to each rendered instance. Replace them with resolveValue(value, colors, uid). Other icons pass fill straight to the root svg.

Subpath entries

The styles define .{prefix}-icon, -extra-small, -small, -default, -large, -extra-large, -spinning and the spin animation, and depend on $prefix from semi:theme. The framework icon packages already import them; import them yourself when using core directly.

Related packages

• Depends on no other Semi package.
• Used by the icon packages of each framework.

Adding icons

• Monochrome icon: add svgs/icons/<name>.svg and an entry in svgs/icons/meta.json. category is the group name on the icon page and reuses existing values such as Basic, Arrow and Interface; AI icons use One Color, Two Color and Multiple Color by color level. Colors become currentColor.
• Color icon: add svgs/lab/<name>.svg and an entry in svgs/lab/meta.json. Colors stay as they are.
• The SVG file name is the icon type, the export name is Icon plus PascalCase (ai_ becomes AI), and the generated module file name is the export name in kebab-case (IconAIBellLevel2 becomes icon-ai-bell-level-2.ts).
• Do not hand-write {uid} for ids in the SVG source. The generator adds the prefix, and rendering replaces it per instance.
• Run pnpm build:icon at the repository root. It first writes src/icons, src/lab and src/illustrations in this package (scripts/build-icon.ts, with a fixed svgo config to keep path data stable), then generates the icon and illustration components of each framework. Do not edit generated files by hand.
• Run pnpm site:dev and open the icon docs page to check the new icon.

Adding illustrations

• Add svgs/illustrations/<name>.svg, and name the dark variant <name>-dark.svg. Colors, width and height stay as they are, with colors written as var(--semi-color-*).
• The export name is Illustration plus PascalCase, so noContent-dark becomes IllustrationNoContentDark.
• Ids also skip the hand-written {uid}. Run pnpm build:icon to generate src/illustrations and the illustration components of each framework.

Development

• Build: vp pack. For general commands, see CONTRIBUTING.md at the repository root.
• Tests: __tests__/data.test.ts checks the ids and references of all icons and illustrations.
