@langgenius/dify-ui

Independent UI primitives, design tokens, CSS-first Tailwind styles, and the cn() utility for Dify products.

Most interactive primitives are thin, opinionated wrappers around Base UI headless components. Dify-authored primitives use semantic HTML, cva, cn, and Dify design tokens. The package is private to the workspace, but its public subpaths are treated as stable package boundaries.

Usage

Add the workspace dependency:

jsonc

{
  "dependencies": {
    "@langgenius/dify-ui": "workspace:*",
  },
}

Import from a public subpath. The package intentionally has no root barrel:

tsx

import { Button } from '@langgenius/dify-ui/button'
import { Dialog, DialogContent, DialogTrigger } from '@langgenius/dify-ui/dialog'
import { Field, FieldLabel } from '@langgenius/dify-ui/field'
import { Input } from '@langgenius/dify-ui/input'
import { cn } from '@langgenius/dify-ui/cn'
import '@langgenius/dify-ui/styles.css'

Import styles.css once from the consumer's root stylesheet or entrypoint.

Guides

Start here, then open only the guide for the contract being changed. Component-specific Dify behavior lives beside the component. Contracts shared by several primitives live in docs/. Upstream behavior remains owned by the Base UI documentation.

Component guides

Guide	Dify-owned contract
Button	Action semantics, submit and link choices, loading versus disabled, and content spacing.
Icon Button	Accessible names, decorative glyphs, appearance ownership, and primitive composition.
Input Group	Compound input anatomy, shared-surface ownership, DOM order, focus, and interactive addons.

Cross-component guides

Guide	Scope
Forms	Native submit boundaries, fields, labels, grouped controls, and errors.
Selection	Typed values and choosing among segmented controls, pickers, and radio groups.
Overlays	Portals, root isolation, layering, trigger composition, and semantics.
Styling	Tailwind CSS integration and the Figma radius mapping.
Public API authoring	Subpath exports, naming, public types, generics, and private helpers.
Testing and development	Package commands, test ownership, accessibility, and animation setup.

Contributing

Read component authoring rules before modifying the package, then open only the matching owner guide. This index intentionally does not duplicate those contracts.
