propeller-v2-vue-ui

A Vue 3 component library for Propeller Commerce storefronts. It ships ready-made e-commerce UI — product cards, grids, carts, checkout, account pages — together with headless composables that talk to the Propeller GraphQL API, plus the shared utilities and types those parts build on.

It is the Vue mirror of propeller-v2-react-ui: same component set, same SDK seam, same styling contract.

The package is framework-flexible within the Vue ecosystem: it runs in any Vue 3.4+ app — a Vite SPA, a Nuxt 3 app — and ships its own precompiled stylesheet, so you do not need Tailwind in your project to use it.

Installation

npm install propeller-v2-vue-ui propeller-sdk-v2 --install-links

propeller-sdk-v2 is a peer dependency — install it yourself so the package and your application share a single SDK instance. --install-links is needed on Windows for file: / github: installs.

Peer dependencies

| Package | Version | Required | | ------------------ | -------- | -------- | | vue | >=3.4 | Yes | | propeller-sdk-v2 | * | Yes |

There is no dependency on Nuxt or vue-router — nothing in the package imports them. A plain Vite + Vue app works out of the box.

Entry points

| Import path | Contents | | ----------------------------- | ----------------------------------------------------- | | propeller-v2-vue-ui | Components, composables, the provider, createServices, toPlain | | propeller-v2-vue-ui/shared | createServices, toPlain, formatters, helpers, types — pure TS | | propeller-v2-vue-ui/pure | SSR-safe presentational components — no composables, no browser APIs | | propeller-v2-vue-ui/styles.css | The precompiled stylesheet |

The /shared entry is plain TypeScript with no Vue dependency — import the pure helpers and createServices from there when you want them outside a component (a Nuxt server route, a build script, a test).

The /pure entry re-exports a curated subset of components that are guaranteed SSR-safe: no composable calls, no window/localStorage/document access, no onMounted fetching. Render them directly into the static shell of a server-rendered page with no hydration mismatch. Mirrors the React package's /pure entry component-for-component.

Core concept: the SDK seam

This is the one architectural idea to understand before using the package.

The package ships no GraphQL client and no hardcoded API endpoint. GraphQL transport is application-specific — a Vite SPA hits the API through its dev proxy; a Nuxt app may use a server route; another app uses a custom rewrite. Baking a URL into a component library would lock it to one app shape.

The contract is three steps:

1. You construct the GraphQLClient from propeller-sdk-v2, with your endpoint, headers and auth resolver.
2. You call createServices(client) once — it returns a typed Services bundle (product, cart, user, order, …) keyed to that client.
3. You install both via providePropeller({ graphqlClient, services, … }).

Inside the provider, every component and composable reads the services via useServices() — they never instantiate the SDK themselves.

createServices is a pure factory, memoized per client via a WeakMap, so calling it again with the same client returns the same bundle. toPlain recursively strips the SDK's underscore-prefixed backing fields so downstream code sees the clean public shape.

Quick start

1. Build the client and services

// src/lib/api.ts — your app owns this file
import { GraphQLClient } from 'propeller-sdk-v2';
import { createServices } from 'propeller-v2-vue-ui';

export const graphqlClient = new GraphQLClient({
  endpoint: import.meta.env.VITE_GRAPHQL_ENDPOINT || '/api/graphql',
  apiKey: import.meta.env.VITE_API_KEY || '',
  timeout: 30_000,
});

export const services = createServices(graphqlClient);

2. Install the provider and the stylesheet

// src/main.ts
import { createApp } from 'vue';
import App from './App.vue';
import 'propeller-v2-vue-ui/styles.css';

createApp(App).mount('#app');

<!-- src/App.vue -->
<script setup lang="ts">
import { providePropeller } from 'propeller-v2-vue-ui';
import { graphqlClient, services } from '@/lib/api';

providePropeller({
  graphqlClient,
  services,
  user: null,            // your auth state (a Contact / Customer or null)
  companyId: undefined,
  language: 'NL',
  includeTax: false,
  currency: '€',
  configuration: {},     // free-form config bag (url builders, image filters)
  portalMode: 'open',
});
</script>

<template>
  <RouterView />
</template>

providePropeller must be called in a component's setup() (typically the root App.vue) so the provide reaches the whole tree.

3. Use components and composables anywhere below the provider

<script setup lang="ts">
import { ProductCard } from 'propeller-v2-vue-ui';
</script>

<template>
  <ProductCard :product="product" />
</template>

The Propeller provider

providePropeller(value) installs a PropellerInfra object for the component subtree. usePropellerContext() reads it (non-throwing — returns null outside a provider).

PropellerInfra fields

| Field | Type | Notes | | --------------- | -------------------------- | ----- | | graphqlClient | GraphQLClient | The client you constructed. | | services | Services | The bundle from createServices(client). | | user | Contact \| Customer \| null | Your auth state. | | companyId | number \| undefined | Active company for B2B pricing. | | language | string | e.g. 'NL', 'EN'. | | includeTax | boolean | Leading price is net (incl. VAT) when true. | | currency | string | Currency symbol for price formatting. | | configuration | unknown | Free-form bag (url builders, image filters). | | portalMode | string | e.g. 'open', 'semi-closed'. |

A component reads infra via useInfraProps(props) — an explicit prop always wins, otherwise the value comes from the provider, otherwise a default. This means components also work standalone (no provider) for tests and Storybook.

Using components

The package exports 60 components. They are prop-driven. Components that need infrastructure resolve it from the provider, so most usages are short:

<ProductGrid :categoryId="17" />
<CartIconAndSidebar />
<Breadcrumbs :categoryPath="category.categoryPath" />

ProductGrid installs a Tier-2 grid config (provideProductGridConfig) that ProductCard / ClusterCard and their subtree consume — so you do not thread display flags and callbacks through by hand.

See STYLING.md for restyling, and the docs site for the full component catalogue.

Partner extension API

Customise nested components (price, stock, add-to-cart, whole card) without forking. See docs/extension-api.md for the full guide covering injection slots, cascade rules, before/after iteration slots, whole-card swap, ProductInfo expanded shell, and contract types.

Using composables

The 15 composables are headless — reactive state + actions, no markup.

import { useCart } from 'propeller-v2-vue-ui';
import { computed } from 'vue';
import { graphqlClient } from '@/lib/api';

const { cart, addItem, loading } = useCart({
  graphqlClient,
  user: computed(() => authStore.user),
  language: computed(() => languageStore.language),
  configuration: { imageSearchFiltersGrid: {}, imageVariantFiltersSmall: {} },
});

Composables that take user / companyId / language expect refs — wrap props or store values with computed() before passing them in, so the composable tracks changes.

The framework-agnostic cart helpers (initCart, fetchActiveCart, mergeAnonymousCart) take a services bundle rather than a raw client.

Styling

The package ships a precompiled stylesheet — import it once:

import 'propeller-v2-vue-ui/styles.css';

Three override surfaces — theme tokens (CSS variables), BEM hook classes, and a per-instance class attribute. Full detail in STYLING.md.
