Integrating a headless CMS with Vue Storefront 2

With the recent rise of composable commerce, integrating headless CMSes into e-commerce websites is becoming increasingly common. One such tool which makes this incredibly straight forward, is Vue Storefront 2.

For those of you who are new to it, Vue Storefront 2 is the latest version of Vue Storefront, which is a platform-agnostic PWA framework for creating e-commerce websites.

In this post we’re going to walk you through how to integrate a headless CMS (specifically LexasCMS 😉) with Vue Storefront 2.

Tutorial

So enough with the preamble, let’s get straight to it! 🚀

In this tutorial we're going to take a freshly generated Vue Storefront 2 project, and replace the homepage hero banner with one that is managed by your headless CMS (in this case LexasCMS).

Pre-requisites

Before getting started with the tutorial, it is recommended that you have the following:

Step 1: Create a new space on LexasCMS

Sign in to your LexasCMS account, and then either create a new organisation or navigate into an existing one.

From within your organisation, create a new space by clicking on the Create Space button and filling out the required information (any plan type will work fine).

Once your new space has been created, open it, and you will be presented with a Select Starter Template modal.

From the modal, select the 'E-commerce Tutorial (Vue Storefront)' template, and then click the Import Template button.

This template will automatically create the content types and sample content which will be needed for this tutorial.

Step 2: Create a new Vue Storefront 2 project

We'll be using the Vue Storefront CLI to generate a new project. If you don't already have this installed, you can install it by running the following command in your terminal:

yarn global add @vue-storefront/cli
Enter fullscreen mode Exit fullscreen mode

Now, generate a new Vue Storefront 2 project using the command below:

Note: When prompted to choose an integration, just select commercetools.

vsf init lexascms-tutorial
Enter fullscreen mode Exit fullscreen mode

This command will create a new lexascms-tutorial directory which will contain the code for your new project.

Once it has finished, navigate into the new project directory and install your projects dependencies:

cd lexascms-tutorial
yarn install
Enter fullscreen mode Exit fullscreen mode

After your projects dependencies are installed, start your development server using the command shown below:

yarn run dev
Enter fullscreen mode Exit fullscreen mode

Once your development server is up and running, navigate to http://localhost:3000 in your web browser and you should see something like the below screenshot.

Step 3: Install LexasCMS integration

Before content can be retrieved from your headless CMS, you'll need to install and configure the Vue Storefront integration of your chosen CMS (in this case LexasCMS).

To install the LexasCMS integration for Vue Storefront, run the following command:

yarn add vsf-lexascms
Enter fullscreen mode Exit fullscreen mode

Once the installation has finished, register the vsf-lexascms integration in your projects nuxt.config.js file as follows:

export default {
  // ...

  buildModules: [
    // ...

    ['vsf-lexascms/nuxt']
  ]

  // ...
};
Enter fullscreen mode Exit fullscreen mode

Next, open the middleware.config.js file in the root of your project and add the following configuration:

Note: Be sure to replace YOUR_SPACE_ID with your actual space ID, which can be found in the Settings > General section of your space control panel.

module.exports = {
  integrations: {
    // ...

    lexascms: {
      location: 'vsf-lexascms/server',
      configuration: {
        spaceId: 'YOUR_SPACE_ID'
      }
    }
  }
};
Enter fullscreen mode Exit fullscreen mode

Now that the integration has been installed and configured, content can be retrieved using the useContent composable. Before we make any changes to our homepage, let's take a look at how it works.

The useContent composable is imported directly from your CMS integration like so:

import { useContent } from 'vsf-lexascms';
Enter fullscreen mode Exit fullscreen mode

The composable then provides access to a search function, and three other properties: content, loading and error.

const { search, content, loading, error } = useContent();
Enter fullscreen mode Exit fullscreen mode
  • search is a function and is used for retrieving content from your CMS (in this case LexasCMS)
  • content, loading and error are all computed properties which are populated by the search function
    • content contains the content which was retrieved by the search function
    • loading is a boolean which communicates whether the search function is currently running or not
    • error is null unless an error is thrown by the search function, in which case this contains the error message

Usage of the search function will vary depending on the CMS that you're integrating with. However, you can find the full documentation for the LexasCMS integration here.

Step 4: Update homepage

Now that you've seen how the useContent composable works, let's use it to fetch the content for your homepage's hero banner.

Start by opening the pages/Home.vue file in your project, and adding the below import statements.

You'll notice that we're also importing the onSSR helper function from Vue Storefront. We'll use this to ensure that content is only fetched during server-side rendering.

<script>
// ...
import { onSSR } from '@vue-storefront/core';
import { useContent } from 'vsf-lexascms';

export default {
  // ...
}
</script>
Enter fullscreen mode Exit fullscreen mode

Next, define a setup function as shown below.

This function uses the useContent composable and onSSR helper function to retrieve all of the promo banners from LexasCMS. These are then made available to your template as the promoBanners variable.

<script>
// ...

export default {
  // ...

  setup() {
    const { content: promoBanners, search } = useContent();

    onSSR(async () => {
      await search({
        type: 'collection',
        contentType: 'promoBanner',
        params: {
          include: 'backgroundImage'
        }
      });
    });

    return { promoBanners }
  },

  // ...
}
</script>
Enter fullscreen mode Exit fullscreen mode

Now that we've retrieved the promo banners, we just need to display them!

Scroll back to the top of the pages/Home.vue file and replace the current usage of the SfHero component so that it looks as follows:

<template>
  <div id="home">
    <SfHero class="hero">
      <SfHeroItem
        v-for="promoBanner in promoBanners"
        :key="promoBanner.id"
        :title="promoBanner.heading"
        :subtitle="promoBanner.subHeading"
        :button-text="promoBanner.buttonText"
        :image="promoBanner.backgroundImage.url"
      />
    </SfHero>

    <!-- ... -->
  </div>
</template>
Enter fullscreen mode Exit fullscreen mode

This will loop through the promoBanners variable from the previous step, and render each of the retrieved promo banners using the SfHeroItem component from Storefront UI.

Restart your development server and navigate to http://localhost:3000 in your web browser.

You should see that the homepage hero banner is now being powered by your CMS content.

Congratulations! You successfully integrated a headless CMS into a Vue Storefront 2 project 🎉.

Summary

In this tutorial, you have learned how simple it is to fetch content from a headless CMS using the useContent composable in Vue Storefront 2.
