writing-storybook-stories	Write or update Storybook stories for Vue components in ComfyUI_frontend. Use when adding, modifying, reviewing, or debugging `.stories.ts` files, Storybook docs, component demos, or visual catalog entries in `src/` or `apps/desktop-ui/`.

Write Storybook Stories for ComfyUI_frontend

Workflow

1. !!!!IMPORTANT Confirm the worktree is on a feat/* or fix/* branch. Base PRs on the local main, not a fork branch.
2. Read the component source first. Understand props, emits, slots, exposed methods, and any supporting types or composables.
3. Read nearby stories before writing anything.
   • Search stories: rg --files src apps | rg '\.stories\.ts$'
   • Inspect title patterns: rg -n "title:\\s*'" src apps --glob '*.stories.ts'
4. If a Figma link is provided, list the states you need to cover before writing stories.
5. Co-locate the story file with the component: ComponentName.stories.ts.
6. Add each variation on separate stories, except hover state. this should be automatically applied by the implementation and not require a separate story.
7. Run Storybook and validation checks before handing off.

Match Local Conventions

• Copy the closest neighboring story instead of forcing one universal template.
• Most repo stories use @storybook/vue3-vite. Some stories under apps/desktop-ui still use @storybook/vue3; keep the local convention for that area.
• Add tags: ['autodocs'] unless the surrounding stories in that area intentionally omit it.
• Use ComponentPropsAndSlots<typeof Component> when it helps with prop and slot typing.
• Keep render functions stateful when needed. Use ref(), computed(), and toRefs(args) instead of mutating Storybook args directly.
• Use args.default or other slot-shaped args when the component content is provided through slots.
• Use ComponentExposed only when a component's exposed API breaks the normal Storybook typing.
• Add decorators for realistic width or background context when the component needs it.

Title Patterns

Do not invent titles from scratch when a close sibling story already exists. Match the nearest domain pattern.

Component area	Typical title pattern
src/components/ui/button/Button.vue	Components/Button/Button
src/components/ui/input/Input.vue	Components/Input
src/components/ui/search-input/SearchInput.vue	Components/Input/SearchInput
src/components/common/SearchBox.vue	Components/Input/SearchBox
src/renderer/extensions/vueNodes/widgets/components/*	Widgets/<WidgetName>
src/platform/assets/components/*	Platform/Assets/<ComponentName>
apps/desktop-ui/src/components/*	Desktop/Components/<ComponentName>
apps/desktop-ui/src/views/*	Desktop/Views/<ViewName>

If multiple patterns seem plausible, follow the closest sibling story in the same folder tree.

Common Story Shapes

Stateful input or v-model

export const Default: Story = {
  render: (args) => ({
    components: { MyComponent },
    setup() {
      const { disabled, size } = toRefs(args)
      const value = ref('Hello world')
      return { value, disabled, size }
    },
    template:
      '<MyComponent v-model="value" :disabled="disabled" :size="size" />'
  })
}

Slot-driven content

const meta: Meta<ComponentPropsAndSlots<typeof Button>> = {
  argTypes: {
    default: { control: 'text' }
  },
  args: {
    default: 'Button'
  }
}

export const SingleButton: Story = {
  render: (args) => ({
    components: { Button },
    setup() {
      return { args }
    },
    template: '<Button v-bind="args">{{ args.default }}</Button>'
  })
}

Variants or edge cases grid

export const AllVariants: Story = {
  render: () => ({
    components: { MyComponent },
    template: `
      <div class="grid gap-4 sm:grid-cols-2">
        <MyComponent />
        <MyComponent disabled />
        <MyComponent loading />
        <MyComponent invalid />
      </div>
    `
  })
}

Figma Mapping

• Extract the named states from the design first.
• Prefer explicit prop-driven stories such as Disabled, Loading, Invalid, WithPlaceholder, AllSizes, or EdgeCases.
• Add an aggregate story such as AllVariants, AllSizes, or EdgeCases when side-by-side comparison is useful.
• Use pseudo-state parameters only if the addon is already configured in this repo.
• If a Figma state cannot be represented exactly, capture the closest prop-driven version and explain the gap in the story docs.

Component-Specific Notes

• Widget components often need a minimal SimplifiedWidget object. Build it in setup() and use computed() when args change widget.options.
• Input and search components often need a width-constrained wrapper so they render at realistic sizes.
• Asset and platform cards often need background decorators such as bg-base-background and fixed-width containers.
• Desktop installer stories may need custom backgrounds parameters and may intentionally keep the older Storybook import style used by neighboring files.
• Use semantic tokens such as bg-base-background and bg-node-component-surface instead of dark: variants or hardcoded theme assumptions.

Checklist

• Read the component source and any supporting types or composables
• Match the nearest local title pattern and story style
• Include a baseline story; name it Default only when that matches nearby conventions
• Add focused stories for meaningful states
• Add tags: ['autodocs']
• Keep the story co-located with the component
• Run pnpm storybook
• Run pnpm typecheck
• Run pnpm lint

Avoid

• Do not guess props, emits, slots, or exposed methods.
• Do not force one generic title convention across the repo.
• Do not mutate Storybook args directly for v-model components.
• Do not introduce dark: Tailwind variants in story wrappers.
• Do not create barrel files.
• Do not assume every story needs layout: 'centered' or a Default export; follow the nearest existing pattern.
