description	Catalogue of every Codex Vue component shipped via @wikimedia/codex — what each component is for, the most common props/slots/events, and which ones to reach for in typical Wikipedia UI patterns. Use when you need a button, input, dialog, menu, message, card, tabs, lookup, etc., or when you're picking between similar components ("Lookup vs TypeaheadSearch?").

Codex components

Codex ships 50+ Vue components. They're the building blocks for every Wikimedia UI. Use a Codex component before writing any custom one.

import { CdxButton, CdxField, CdxTextInput, CdxIcon, CdxMessage } from '@wikimedia/codex'

The package is fully tree-shakable — only the components you import end up in your route bundle.

Composition patterns

Form field

<CdxField>
  <template #label>Article title</template>
  <template #description>What you'd like to suggest.</template>
  <CdxTextInput v-model="title" />
</CdxField>

Action with progress

<CdxButton :disabled="loading" action="progressive" weight="primary" @click="submit">
  <CdxProgressIndicator v-if="loading" inline />
  Publish
</CdxButton>

Notice + dismiss

<CdxMessage type="warning" :allow-user-dismiss="true" @user-dismissed="hide">
  This is a draft. Changes haven't been saved.
</CdxMessage>

Modal

<CdxDialog
  v-model:open="showModal"
  title="Discard changes?"
  :primary-action="{ label: 'Discard', actionType: 'destructive' }"
  :default-action="{ label: 'Keep editing' }"
  @primary="discard"
  @default="showModal = false"
>
  All unsaved changes will be lost.
</CdxDialog>

Common pitfalls

• Forgetting CdxField. A bare CdxTextInput has no label — wrap it.
• Confusing CdxLookup and CdxTypeaheadSearch. Lookup is for form values (you must pick from suggestions); TypeaheadSearch is for search navigation (you can submit free text, like the wiki search bar).
• Re-importing Codex CSS. It's already global. Don't.
• Wrapping an icon in a button manually. Use <CdxButton> with a child <CdxIcon> — focus styles, hover, sizing all come for free.

Inside ProtoWiki

ProtoWiki composes these primitives into wrappers (ChromeWrapper, SpecialPageWrapper, PlainWrapper) and reader surfaces (ArticleWrapper, ArticleRenderer, ArticleLive, ArticleSnapshot, ArticleCustom, …; Search wraps CdxTypeaheadSearch). See protowiki-components.
