shopware/frontends - composables-next

Set of Vue.js composition functions that can be used in any Vue.js project. They provide state management, UI logic and data fetching and are the base for all guides in our building section.

Features

• createShopwareContext method to create a Vue 3 plugin to install
• State management
• Logic for UI
• Communication with Store-API via api-client package

Setup

Install npm packages (composables & api-client):

# Using pnpm
pnpm add @shopware-pwa/composables-next @shopware/api-client @shopware/api-gen

# Using yarn
yarn add @shopware-pwa/composables-next @shopware/api-client @shopware/api-gen

# Using npm
npm i @shopware-pwa/composables-next @shopware/api-client @shopware/api-gen

Now generate your types ysing the CLI:

pnpm shopware-api-gen generate --apiType=store

Initialize the api-client instance:

import { createAPIClient } from "@shopware/api-client";
import type { operations } from "#shopware";

export const apiClient = createAPIClient<operations>({
  baseURL: "https://your-api-instance.com",
  accessToken: "your-sales-channel-access-token",
});

// and then provide it in the Vue app
app.provide("apiClient", apiClient);

Now, we can create a Vue 3 plugin to install a Shopware context in an app:

// app variable in type of App

const shopwareContext = createShopwareContext(app, {
  devStorefrontUrl: "https://your-sales-channel-configured-domain.com",
});
// register a plugin in a Vue instance
app.use(shopwareContext);

The example does not provide the session handling and that means you need to do few additional steps if you need to keep your session after the page reload (see the chapter below with 🍪)

Basic usage

Now you can use any composable function in your setup function:

<script setup>
    import { useUser, useSessionContext } from "@shopware-pwa/composables-next/dist";

    const { login } = useUser();
    const { refreshSessionContext, sessionContext } = useSessionContext();
    refreshSessionContext();
</script>
<template>
    <pre>{{ sessionContext }}</pre>
    <button @click="login({
        username: "some-user",
        password: "secret-passwd"
    })">
        Try to login!
    </button>
</template>

Session persistence with 🍪

By default, the API-Client is stateless, but accepts an optional context token as a parameter while initializing an instance. In order to keep a session, install some cookie parser to work with cookies easier:

# Using pnpm
pnpm add js-cookie

# Using yarn
yarn add js-cookie

# Using npm
npm i js-cookie

Let's get back to the step where the api-client was initialized:

import { createAPIClient } from "@shopware/api-client";
import type { operations } from "#shopware";
import Cookies from "js-cookie";

const shopwareEndpoint = "https://demo-frontends.shopware.store/store-api";

export const apiClient = createAPIClient<operations>({
  baseURL: shopwareEndpoint,
  accessToken: "SWSCBHFSNTVMAWNZDNFKSHLAYW",
  contextToken: Cookies.get("sw-context-token"),
});

apiClient.hook("onContextChanged", (newContextToken) => {
  Cookies.set("sw-context-token", newContextToken, {
    expires: 365, // days
    path: "/",
    sameSite: "lax",
    secure: shopwareEndpoint.startsWith("https://"),
  });
});

Thanks to this, the session will be kept to the corresponding sw-context-token saved in the cookie, so it can be reachable also in the SSR. Check the example to see it in action:

TypeScript support

All composable functions are fully typed with TypeScript and they are registed globally in Nuxt.js application, so the type hinting will help you to work with all of them.
