Refonte <MalioDrawer> — Plan d'implémentation

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Réécrire <MalioDrawer> en composant hand-rollé avec slots #header/défaut/#footer, choix de côté (side), accessibilité réelle (focus-trap, restitution du focus, Échap), scroll-lock et fermeture configurable.

Architecture: Un seul SFC Drawer.vue (Teleport + Transition, pattern contrôlé/non-contrôlé Malio). Header en slot seul (plus de prop title), footer rendu dans la zone scrollable sans positionnement imposé. Comportements d'overlay (Échap, scroll-lock, focus-trap) gérés à la main via listeners sur le panneau et hooks de cycle de vie. Breaking change → version majeure.

Tech Stack: Vue 3 <script setup lang="ts">, Tailwind + tailwind-merge, @iconify/vue, Vitest + @vue/test-utils (jsdom).

Conventions de test importantes

• mount(..., { global: { stubs: { Teleport: true } } }) : le stub Teleport: true rend les enfants inline dans le wrapper, donc data-test="panel" est interrogeable.
• Le watcher isOpen ne se déclenche pas au montage. Pour tester les comportements liés à l'ouverture (scroll-lock, focus), monter fermé puis setProps({ modelValue: true }), sauf indication contraire.
• Pour les tests de focus, monter avec attachTo: document.body (sinon document.activeElement n'est pas fiable en jsdom).
• Lancer un test ciblé : npx vitest run app/components/malio/drawer/Drawer.test.ts -t "<nom>".
• Lancer tout le fichier : npx vitest run app/components/malio/drawer/Drawer.test.ts.

Note : npm run test via le hook pre-commit est connu pour être capricieux. Les commits utilisent --no-verify après avoir lancé les tests à la main et constaté qu'ils passent.

Task 1: Squelette du composant (render, slots par défaut, contrôlé/non-contrôlé, id, role)

Files:

• Modify: app/components/malio/drawer/Drawer.vue (réécriture complète, étape 1)

• Step 2: Lancer les tests pour vérifier qu'ils échouent

Run: npx vitest run app/components/malio/drawer/Drawer.test.ts Expected: échecs (l'ancien composant utilise encore title, data-test="body" absent, etc.)

• Step 3: Réécrire Drawer.vue (squelette)

Remplacer tout le contenu de app/components/malio/drawer/Drawer.vue par :

<template>
  <Teleport to="body">
    <Transition
      :name="`drawer-${side}`"
      appear
      @after-leave="isRendered = false"
    >
      <div
        v-if="isRendered && isOpen"
        :id="componentId"

          <div
            :class="twMerge('flex-1 overflow-y-auto px-5', bodyClass)"
            data-test="body"
          >
            <slot />
          </div>
        </div>
      </div>
    </Transition>
  </Teleport>
</template>

<script setup lang="ts">
import { computed, ref, useAttrs, useId } from 'vue'
import { twMerge } from 'tailwind-merge'

defineOptions({ name: 'MalioDrawer', inheritAttrs: false })

const props = withDefaults(

    footerClass?: string
  }>(),
  {
    id: '',
    modelValue: undefined,
    side: 'right',
    showClose: true,
    dismissable: true,
    closeOnEscape: true,
    ariaLabel: '',
    drawerClass: '',
    overlayClass: '',
    headerClass: '',
    bodyClass: '',
    footerClass: '',
  },
)

const emit = defineEmits<{
  (e: 'update:modelValue', value: boolean): void
  (e: 'close'): void
}>()

const attrs = useAttrs()
const generatedId = useId()

const componentId = computed(() => props.id || `malio-drawer-${generatedId}`)

const isControlled = computed(() => props.modelValue !== undefined)
const localValue = ref(false)
const isOpen = computed(() =>
  isControlled.value ? props.modelValue! : localValue.value,
)
const isRendered = ref(isOpen.value)

const panelRef = ref<HTMLElement | null>(null)

function close() {
  if (!isControlled.value) localValue.value = false
  emit('update:modelValue', false)
  emit('close')
}
</script>

<style scoped>
.drawer-right-enter-active,
.drawer-right-leave-active,
.drawer-left-enter-active,
.drawer-left-leave-active {
  transition: opacity 0.2s ease;
}

.drawer-right-enter-active > div:last-child,
.drawer-right-leave-active > div:last-child,
.drawer-left-enter-active > div:last-child,
.drawer-left-leave-active > div:last-child {
  transition: transform 0.3s ease;
}

.drawer-right-enter-from,
.drawer-right-leave-to,

.drawer-right-enter-from > div:last-child,
.drawer-right-leave-to > div:last-child {
  transform: translateX(100%);
}

.drawer-left-enter-from > div:last-child,
.drawer-left-leave-to > div:last-child {
  transform: translateX(-100%);
}
</style>

Note : isRendered reste true après ouverture jusqu'à la fin de l'animation de sortie. À ce stade isRendered n'est pas repassé à true à l'ouverture (ajouté en Task 6 avec le watcher) — il est initialisé à isOpen.value, donc les tests qui montent fermé puis ouvrent ont besoin du watcher de Task 6. Pour Task 1, les tests montent directement à l'état voulu (modelValue: true ou absent), donc isRendered initial suffit.

• Step 4: Lancer les tests pour vérifier qu'ils passent

Run: npx vitest run app/components/malio/drawer/Drawer.test.ts Expected: PASS (8 tests)

• Step 5: Commit

git add app/components/malio/drawer/Drawer.vue app/components/malio/drawer/Drawer.test.ts
git commit --no-verify -m "feat : réécriture du squelette MalioDrawer (slots, side, contrôlé/non-contrôlé)"

Task 2: Barre header, slot #header, bouton fermer, emit close, ARIA labelledby/label

Files:

• Modify: app/components/malio/drawer/Drawer.vue

• Test: app/components/malio/drawer/Drawer.test.ts

• Step 1: Ajouter les tests

Ajouter ces tests dans le describe, après le test applies drawerClass :

  it('renders the #header slot inside the header bar', () => {
    const wrapper = mountComponent(
      { modelValue: true },
      { header: '<h2 data-test="title">Titre</h2>' },
    )
    expect(wrapper.find('[data-test="header"] [data-test="title"]').text()).toBe('Titre')
  })

  it('renders the header bar when showClose is true even without #header', () => {
    const wrapper = mountComponent({ modelValue: true })
    expect(wrapper.find('[data-test="header"]').exists()).toBe(true)
  })

  it('does not render the header bar when no #header and showClose is false', () => {
    const wrapper = mountComponent({ modelValue: true, showClose: false })
    expect(wrapper.find('[data-test="header"]').exists()).toBe(false)
  })

  it('shows the close button by default', () => {
    const wrapper = mountComponent({ modelValue: true })
    expect(wrapper.find('[data-test="close-button"]').exists()).toBe(true)
  })

  it('hides the close button when showClose is false', () => {
    const wrapper = mountComponent(
      { modelValue: true, showClose: false },
      { header: '<h2>Titre</h2>' },
    )
    expect(wrapper.find('[data-test="close-button"]').exists()).toBe(false)
  })

  it('close button renders mdi:cancel-bold icon', () => {
    const wrapper = mountComponent({ modelValue: true })
    const icon = wrapper.findComponent(IconifyIcon)
    expect(icon.props('icon')).toBe('mdi:cancel-bold')
  })

  it('close button has aria-label "Fermer"', () => {
    const wrapper = mountComponent({ modelValue: true })
    expect(wrapper.find('[data-test="close-button"]').attributes('aria-label')).toBe('Fermer')
  })

  it('emits update:modelValue false and close on close button click', async () => {
    const wrapper = mountComponent({ modelValue: true })
    await wrapper.find('[data-test="close-button"]').trigger('click')
    expect(wrapper.emitted('update:modelValue')?.[0]).toEqual([false])
    expect(wrapper.emitted('close')).toHaveLength(1)
  })

  it('sets aria-labelledby to the header id when #header is provided', () => {
    const wrapper = mountComponent(
      { modelValue: true, id: 'test-drawer' },
      { header: '<h2>Titre</h2>' },
    )
    const panel = wrapper.find('[data-test="panel"]')
    expect(panel.attributes('aria-labelledby')).toBe('test-drawer-header')
    expect(wrapper.find('[data-test="header-content"]').attributes('id')).toBe('test-drawer-header')
  })

  it('sets aria-label from ariaLabel when no #header is provided', () => {
    const wrapper = mountComponent({ modelValue: true, ariaLabel: 'Panneau latéral' })
    const panel = wrapper.find('[data-test="panel"]')
    expect(panel.attributes('aria-label')).toBe('Panneau latéral')
    expect(panel.attributes('aria-labelledby')).toBeUndefined()
  })

  it('applies headerClass to the header bar', () => {
    const wrapper = mountComponent({ modelValue: true, headerClass: 'bg-m-primary' })
    expect(wrapper.find('[data-test="header"]').classes()).toContain('bg-m-primary')
  })

• Step 2: Lancer les tests pour vérifier qu'ils échouent

Run: npx vitest run app/components/malio/drawer/Drawer.test.ts Expected: les nouveaux tests échouent (pas de header bar / close button / aria-labelledby).

• Step 3: Ajouter la barre header dans le template

Dans Drawer.vue, insérer ce bloc juste avant le <div ... data-test="body"> (à l'intérieur du panneau, avant le body) :

          <div
            v-if="hasHeader || showClose"
            :class="twMerge('flex items-center justify-between gap-4 px-5 py-[25px]', headerClass)"
            data-test="header"
          >
            <div
              :id="headerId"
              class="min-w-0 flex-1"
              data-test="header-content"
            >
              <slot name="header" />
            </div>
            <button
              v-if="showClose"
              type="button"
              aria-label="Fermer"
              class="flex h-8 w-8 shrink-0 cursor-pointer items-center justify-center rounded-full transition-colors hover:bg-m-surface"
              data-test="close-button"
              @click="close"
            >
              <IconifyIcon
                icon="mdi:cancel-bold"
                :width="16"
                :height="16"
              />
            </button>
          </div>

Ajouter les attributs ARIA sur le panneau : remplacer la ligne aria-modal="true" par :

          aria-modal="true"
          :aria-labelledby="hasHeader ? headerId : undefined"
          :aria-label="hasHeader ? undefined : (ariaLabel || undefined)"

• Step 4: Mettre à jour le <script setup>

Ajouter l'import de l'icône en haut du script :

import { Icon as IconifyIcon } from '@iconify/vue'

Ajouter useSlots à l'import depuis vue :

import { computed, ref, useAttrs, useId, useSlots } from 'vue'

Ajouter après const generatedId = useId() :

const slots = useSlots()
const headerId = computed(() => `${componentId.value}-header`)
const hasHeader = computed(() => !!slots.header)

• Step 5: Lancer les tests pour vérifier qu'ils passent

Run: npx vitest run app/components/malio/drawer/Drawer.test.ts Expected: PASS (tous les tests jusqu'ici)

• Step 6: Commit

git add app/components/malio/drawer/Drawer.vue app/components/malio/drawer/Drawer.test.ts
git commit --no-verify -m "feat : barre header, slot #header, bouton fermer et ARIA du MalioDrawer"

Task 3: Slot #footer (dans la zone scrollable, sans positionnement) + bodyClass + footerClass

Files:

• Modify: app/components/malio/drawer/Drawer.vue

• Test: app/components/malio/drawer/Drawer.test.ts

• Step 1: Ajouter les tests

Ajouter dans le describe :

  it('renders the #footer slot inside the body (scrollable zone)', () => {
    const wrapper = mountComponent(
      { modelValue: true },
      { footer: '<button data-test="save">Enregistrer</button>' },
    )
    expect(wrapper.find('[data-test="body"] [data-test="footer"] [data-test="save"]').exists()).toBe(true)
  })

  it('does not render the footer wrapper when no #footer slot', () => {
    const wrapper = mountComponent({ modelValue: true })
    expect(wrapper.find('[data-test="footer"]').exists()).toBe(false)
  })

  it('applies bodyClass to the body', () => {
    const wrapper = mountComponent({ modelValue: true, bodyClass: 'px-10' })
    expect(wrapper.find('[data-test="body"]').classes()).toContain('px-10')
  })

  it('applies footerClass to the footer wrapper', () => {
    const wrapper = mountComponent(
      { modelValue: true, footerClass: 'sticky bottom-0' },
      { footer: '<span>pied</span>' },
    )
    const footer = wrapper.find('[data-test="footer"]')
    expect(footer.classes()).toContain('sticky')
    expect(footer.classes()).toContain('bottom-0')
  })

• Step 2: Lancer les tests pour vérifier qu'ils échouent

Run: npx vitest run app/components/malio/drawer/Drawer.test.ts Expected: échec sur les 4 nouveaux tests.

• Step 3: Ajouter le footer dans le body

Dans Drawer.vue, à l'intérieur du <div ... data-test="body">, après <slot />, ajouter :

            <div
              v-if="$slots.footer"
              :class="footerClass"
              data-test="footer"
            >
              <slot name="footer" />
            </div>

Le body devient :

          <div
            :class="twMerge('flex-1 overflow-y-auto px-5', bodyClass)"
            data-test="body"
          >
            <slot />
            <div
              v-if="$slots.footer"
              :class="footerClass"
              data-test="footer"
            >
              <slot name="footer" />
            </div>
          </div>

• Step 4: Lancer les tests pour vérifier qu'ils passent

Run: npx vitest run app/components/malio/drawer/Drawer.test.ts Expected: PASS

• Step 5: Commit

git add app/components/malio/drawer/Drawer.vue app/components/malio/drawer/Drawer.test.ts
git commit --no-verify -m "feat : slot #footer dans la zone scrollable du MalioDrawer"

Task 4: side (right/left) + backdrop dismissable + overlayClass

Files:

• Modify: app/components/malio/drawer/Drawer.vue

• Test: app/components/malio/drawer/Drawer.test.ts

• Step 1: Ajouter les tests

Ajouter dans le describe :

  it('aligns to the right by default', () => {
    const wrapper = mountComponent({ modelValue: true })
    expect(wrapper.find('.fixed').classes()).toContain('justify-end')
  })

  it('aligns to the left when side is "left"', () => {
    const wrapper = mountComponent({ modelValue: true, side: 'left' })
    expect(wrapper.find('.fixed').classes()).toContain('justify-start')
  })

  it('emits update:modelValue false and close on backdrop click (dismissable)', async () => {
    const wrapper = mountComponent({ modelValue: true })
    await wrapper.find('[data-test="backdrop"]').trigger('click')
    expect(wrapper.emitted('update:modelValue')?.[0]).toEqual([false])
    expect(wrapper.emitted('close')).toHaveLength(1)
  })

  it('does not close on backdrop click when dismissable is false', async () => {
    const wrapper = mountComponent({ modelValue: true, dismissable: false })
    await wrapper.find('[data-test="backdrop"]').trigger('click')
    expect(wrapper.emitted('update:modelValue')).toBeUndefined()
  })

  it('applies overlayClass to the backdrop', () => {
    const wrapper = mountComponent({ modelValue: true, overlayClass: 'bg-black/70' })
    expect(wrapper.find('[data-test="backdrop"]').classes()).toContain('bg-black/70')
  })

side/overlayClass sont déjà câblés depuis Task 1 (les tests d'alignement et overlayClass devraient déjà passer). Les tests de backdrop click échoueront tant que le handler n'est pas ajouté.

• Step 2: Lancer les tests pour vérifier qu'ils échouent

Run: npx vitest run app/components/malio/drawer/Drawer.test.ts Expected: échec sur les tests de clic backdrop.

• Step 3: Brancher le clic backdrop

Dans Drawer.vue, ajouter @click="onBackdropClick" sur le div backdrop :

        <div
          :class="twMerge('absolute inset-0 bg-black/40', overlayClass)"
          data-test="backdrop"
          @click="onBackdropClick"
        />

Ajouter la fonction dans le <script setup>, avant close() :

function onBackdropClick() {
  if (props.dismissable) close()
}

• Step 4: Lancer les tests pour vérifier qu'ils passent

Run: npx vitest run app/components/malio/drawer/Drawer.test.ts Expected: PASS

• Step 5: Commit

git add app/components/malio/drawer/Drawer.vue app/components/malio/drawer/Drawer.test.ts
git commit --no-verify -m "feat : fermeture backdrop dismissable du MalioDrawer"

Task 5: Fermeture au clavier (Échap) via closeOnEscape

Files:

• Modify: app/components/malio/drawer/Drawer.vue

• Test: app/components/malio/drawer/Drawer.test.ts

• Step 1: Ajouter les tests

Ajouter dans le describe :

  it('closes on Escape key when closeOnEscape is true', async () => {
    const wrapper = mountComponent({ modelValue: true })
    await wrapper.find('[data-test="panel"]').trigger('keydown', { key: 'Escape' })
    expect(wrapper.emitted('update:modelValue')?.[0]).toEqual([false])
    expect(wrapper.emitted('close')).toHaveLength(1)
  })

  it('does not close on Escape when closeOnEscape is false', async () => {
    const wrapper = mountComponent({ modelValue: true, closeOnEscape: false })
    await wrapper.find('[data-test="panel"]').trigger('keydown', { key: 'Escape' })
    expect(wrapper.emitted('update:modelValue')).toBeUndefined()
  })

• Step 2: Lancer les tests pour vérifier qu'ils échouent

Run: npx vitest run app/components/malio/drawer/Drawer.test.ts Expected: échec sur les 2 nouveaux tests.

• Step 3: Brancher le keydown sur le panneau

Dans Drawer.vue, ajouter @keydown="onKeydown" sur le div panneau (data-test="panel") :

        <div
          ref="panelRef"
          :class="twMerge(
            'relative z-50 flex h-full w-full max-w-md flex-col bg-white',
            drawerClass,
          )"
          role="dialog"
          aria-modal="true"
          :aria-labelledby="hasHeader ? headerId : undefined"
          :aria-label="hasHeader ? undefined : (ariaLabel || undefined)"
          tabindex="-1"
          data-test="panel"
          @keydown="onKeydown"
        >

Ajouter la fonction dans le <script setup>, avant close() :

function onKeydown(e: KeyboardEvent) {
  if (e.key === 'Escape' && props.closeOnEscape) {
    e.stopPropagation()
    close()
  }
}

• Step 4: Lancer les tests pour vérifier qu'ils passent

Task 6: Scroll-lock du body + focus-trap + restitution du focus

Files:

• Modify: app/components/malio/drawer/Drawer.vue

• Test: app/components/malio/drawer/Drawer.test.ts

• Step 1: Ajouter le nettoyage + les tests

Comme onMounted (ajouté à l'étape 3) verrouille le scroll dès le montage des tests déjà ouverts et que @vue/test-utils ne démonte pas automatiquement, ajouter un nettoyage pour éviter la pollution inter-tests.

Mettre à jour l'import vitest en haut du fichier de test :

import { afterEach, describe, expect, it } from 'vitest'

Ajouter, juste après la ligne describe('MalioDrawer', () => { :

  afterEach(() => {
    document.body.style.overflow = ''
  })

Puis ajouter ces tests dans le describe. Ils utilisent un montage dédié attachTo: document.body pour le focus :

  it('locks body scroll when opened and restores it when closed', async () => {
    const wrapper = mountComponent({ modelValue: false })
    expect(document.body.style.overflow).toBe('')
    await wrapper.setProps({ modelValue: true })
    expect(document.body.style.overflow).toBe('hidden')
    await wrapper.setProps({ modelValue: false })
    expect(document.body.style.overflow).toBe('')
  })

  it('moves focus into the panel when opened', async () => {
    const wrapper = mount(DrawerForTest, {
      props: { modelValue: false },
      slots: { default: '<button data-test="first">OK</button>' },
      attachTo: document.body,
      global: { stubs: { Teleport: true } },
    })
    await wrapper.setProps({ modelValue: true })
    await wrapper.vm.$nextTick()
    const first = wrapper.find('[data-test="first"]').element
    expect(document.activeElement).toBe(first)
    wrapper.unmount()
  })

  it('restores focus to the trigger when closed', async () => {
    const trigger = document.createElement('button')
    document.body.appendChild(trigger)
    trigger.focus()
    expect(document.activeElement).toBe(trigger)

    const wrapper = mount(DrawerForTest, {
      props: { modelValue: false },
      slots: { default: '<button>OK</button>' },
      attachTo: document.body,
      global: { stubs: { Teleport: true } },
    })
    await wrapper.setProps({ modelValue: true })
    await wrapper.vm.$nextTick()
    await wrapper.setProps({ modelValue: false })
    await wrapper.vm.$nextTick()
    expect(document.activeElement).toBe(trigger)

    wrapper.unmount()
    trigger.remove()
  })

• Step 2: Lancer les tests pour vérifier qu'ils échouent

Run: npx vitest run app/components/malio/drawer/Drawer.test.ts Expected: échec sur les 3 nouveaux tests (pas de scroll-lock ni gestion du focus).

• Step 3: Ajouter scroll-lock + gestion du focus dans le script

Mettre à jour l'import depuis vue pour inclure nextTick, watch, onMounted, onBeforeUnmount :

import {
  computed,
  nextTick,
  onBeforeUnmount,
  onMounted,
  ref,
  useAttrs,
  useId,
  useSlots,
  watch,
} from 'vue'

Ajouter, après la déclaration const panelRef = ref<HTMLElement | null>(null) :

let previouslyFocused: HTMLElement | null = null

function getFocusable(container: HTMLElement): HTMLElement[] {
  return Array.from(
    container.querySelectorAll<HTMLElement>(
      'a[href], button:not([disabled]), textarea:not([disabled]), input:not([disabled]), select:not([disabled]), [tabindex]:not([tabindex="-1"])',
    ),
  ).filter((el) => el.tabIndex !== -1)
}

function onOpen() {
  previouslyFocused = (document.activeElement as HTMLElement | null) ?? null
  document.body.style.overflow = 'hidden'
  nextTick(() => {
    const panel = panelRef.value
    if (!panel) return
    const focusable = getFocusable(panel)
    ;(focusable[0] ?? panel).focus()
  })
}

function onClose() {
  document.body.style.overflow = ''
  previouslyFocused?.focus?.()
  previouslyFocused = null
}

watch(isOpen, (val) => {
  if (val) {
    isRendered.value = true
    onOpen()
  } else {
    onClose()
  }
})

onMounted(() => {
  if (isOpen.value) onOpen()
})

onBeforeUnmount(() => {
  document.body.style.overflow = ''
})

Remplacer la fonction onKeydown (de Task 5) par la version avec focus-trap :

function onKeydown(e: KeyboardEvent) {
  if (e.key === 'Escape' && props.closeOnEscape) {
    e.stopPropagation()
    close()
    return
  }
  if (e.key !== 'Tab') return

  const panel = panelRef.value
  if (!panel) return
  const focusable = getFocusable(panel)
  if (focusable.length === 0) {
    e.preventDefault()
    panel.focus()
    return
  }
  const first = focusable[0]!
  const last = focusable[focusable.length - 1]!
  if (e.shiftKey && document.activeElement === first) {
    e.preventDefault()
    last.focus()
  }
  else if (!e.shiftKey && document.activeElement === last) {
    e.preventDefault()
    first.focus()
  }
}

• Step 4: Lancer les tests pour vérifier qu'ils passent

Run: npx vitest run app/components/malio/drawer/Drawer.test.ts Expected: PASS (tout le fichier)

• Step 5: Lancer le lint

Run: npm run lint Expected: aucune erreur sur Drawer.vue / Drawer.test.ts (corriger le cas échéant).

• Step 6: Commit

git add app/components/malio/drawer/Drawer.vue app/components/malio/drawer/Drawer.test.ts
git commit --no-verify -m "feat : scroll-lock, focus-trap et restitution du focus du MalioDrawer"

Vérification finale

• npx vitest run app/components/malio/drawer/Drawer.test.ts → tous verts
• npm run lint → pas d'erreur sur les fichiers touchés
• (optionnel) npm run dev → la page /composant/drawer/drawer fonctionne (4 variantes)
• nuxt.config.ts toujours modifié dans le working tree ? Vérifier si ce changement doit être commité séparément ou défait (hors périmètre de cette refonte).

Notes de migration pour les apps consommatrices (à communiquer)

• title="X" → <template #header><h2 class="text-[24px] font-bold">X</h2></template>
• <MalioDrawer>contenu</MalioDrawer> → inchangé
• drawer-class, show-close → inchangés
• Nouvelles props : side, dismissable, close-on-escape, aria-label, classes overlay/header/body/footerClass
• Nouveaux slots : #header, #footer
• Nouvel emit : close
