Build an E-commerce Site with Sanity and Commerce Layer

One of the greatest benefits of composable, headless commerce is the flexibility it introduces to the developer experience of building shopping experiences. Decoupling website content and commerce data makes it easier for content and commerce teams of experts to work independently and more efficiently. With Commerce Layer, content managers can work with a best-of-breed headless CMS like Sanity, merchants can build their inventory in Commerce Layer, and developers can build with any stack in their most preferred programming language while utilizing Commerce Layer’s APIs. In this tutorial, you will learn how we built the with Nextjs, Sanity studio, and deployed it to Netlify. At the end of the tutorial, you should be able to set up and build your own 1-click sanity starter with ease or integrate with Commerce Layer. Commerce Layer Starter Prerequisites Git installed (Learn how to install Git if you haven't already). here Node and NPM installed (Learn how to install Nodejs if you haven't already). here Basic knowledge of how to use the terminal. Basic knowledge of NPM. A grin on your face 😉. Introduction to Commerce Layer is a transactional commerce API and order management for international brands. It lets you make any digital experience shoppable, anywhere. You can build a multi-language website with Shopify, Contentful, WordPress, or any other CMS you already love. Then, add Commerce Layer for multi-currency prices, distributed inventory, localized payment gateways, promotions, orders, subscriptions, and more. Commerce Layer Unlike traditional solutions, . It natively supports the most modern development workflows, such as the Jamstack. Ecommerce businesses can integrate Commerce Layer with a single backend and serve on multiple presentation layers enabling them to build outstanding shopping experiences, go headless, and scale their business globally. You can check out our to learn more and get started. Commerce Layer was built for the new era developer resources Introducing Sanity Studio The Sanity studio is an open-source content management system built with React.js. It offers rapid configuration, free form customization, reusable structured content, a comfortable editor, real-time collaboration, toolkits, plugins, and more features to enable you to create the best content workflow. Sanity provides the possibility to create starter templates that can be re-used by developers easily. The starter is primarily a repository hosted on GitHub that contains some meta-information, demo content, schema, and frontend(s) that will end up in a new repository when a developer installs the starter through . When a developer installs the starter, Sanity creates a new project on Sanity and a new repository on GitHub with the starter code, attaches a new Sanity to the starter, and deploys the project to Netlify simultaneously. sanity.io/starters datasetId Generally, a sanity starter can include a Sanity studio, a frontend application, both or multiple frontends and studios. For the purpose of this tutorial, we will create a starter that will include a studio and frontend. Our starter will include: An ecommerce storefront built with Nextjs and . Commerce Layer react components library International shopping capabilities powered by . Commerce Layer APIs Some ecommerce data imported using the . Commerce Layer CLI Structured content on Sanity studio. Localization support. Deployment configuration settings to Netlify. Sanity Starter Project Structure Sanity has a defined specification for starters which includes some required files and directories. These specifications provide information about the starter to developers using the starter and make the project function as a reusable starter. Below is the folder structure of a Sanity project with required files and directories (without any frontend added): ├── .sanity-template ├── .sanity-template/assets ├── .sanity-template/data ├── .sanity-template/manifest.json ├── README.md is the root directory where all meta-information for using this repository as a template on is stored. .sanity-template sanity.io/starters is the directory for storing assets related to displaying information about the starter. In this case, preview images for the overall project and for each site the starter contains. .sanity-template/assets is the directory to store a Sanity dataset export if you want the starter to launch with some demo content. .sanity-template/data is the JSON file containing details about the Starter as well as deployment information. .sanity-template/manifest.json is the markdown file for this project that will be displayed on the Create page. README.md For a finished starter project, the root of the project should contain all deployable code, including the frontend and studio. Generally, a project spun from a starter is split into three parts: The root for all frontend code The directory for all studio code. /studio The for all starter meta-information. .sanity-template Here is a sample from the as seen in the image below: Commerce Layer sanity starter How We Built the Commerce Layer Sanity Starter In this section, you will learn how we built a starter with an ecommerce application with transactional functionalities powered by APIs, structured content on Sanity, imported seed data, and deployment configuration to Netlify. If you want to follow along with the guide, you can take a look at the finished project on GitHub or even install the starter . Commerce Layer here here Here is a sequential breakdown of all the steps taken to develop a starter: 1️⃣ Setup a new Sanity project using the Sanity CLI Sanity has a command-line interface that we can use to interact with Sanity, create new projects, manage datasets, import data, and much more from the CLI. We'll use this CLI to set up a new sanity project following the steps below: 1: Install the CLI Run the command below to install the Sanity CLI. npm install -g @sanity/cli 2: Create a new project Run the command below to bootstrap a new project which will log you into Sanity, create a new project, set up a dataset, and generate the files needed to run the studio environment locally. sanity init 3: Run the studio Run the command below to build the initial JavaScript code required to run the studio, and start a local web server. sanity start The studio should now run on . You can always run to get an overview of other available and useful commands in the Sanity CLI. [localhost:3333](http://localhost:3333) sanity help 2️⃣ Content modeling for the created Sanity studio Now that we understand how Sanity works and have set up a new sanity project, let's structure our sanity studio schema. Sanity schema defines how your content should be modeled, and this structure reflects in the studio UI. The schema describes the different field types a document consists of. Sanity uses the file in the directory to determine the content model of the project. schema.js /schemas With Sanity, you define a block of content as a document or split your documents into modules and import them into the parent file. Generally, there are three categories of Sanity schema types: schema.js Document types ( and other published custom schemas) document Primitive types (e.g., , , , , , , and ) boolean string text number array datetime URL Object types (e.g., , , , , , , and ) object block span reference slug image file You can find all of the Sanity’s types in this or learn how to structure your content model based on your needs by reading . For the Commerce Layer starter, our looks like so in the snippet below with imports of several other module documents. You can view the schema code for each module in the GitHub repository. reference documentation this comprehensive guide schema.js here import createSchema from 'part:@sanity/base/schema-creator' import schemaTypes from 'all:part:@sanity/base/schema-type' // We import object and document schemas import product from './product' import country from './country' import variant from './variant' import size from './size' import taxon from './taxon' import taxonomy from './taxonomy' import catalog from './catalog' import blockContent from './blockContent' import productImage from './productImage' import localeString from './locale/String' import localeText from './locale/Text' import localeSlug from './locale/Slug' import localeBlockContent from './locale/BlockContent' // Then we give our schema to the builder and provide the result to Sanity export default createSchema({ // We name our schema name: 'default', // Then proceed to concatenate our document type // to the ones provided by any plugins that are installed types: schemaTypes.concat([ // The following are document types which will appear // in the studio. product, country, variant, size, taxon, taxonomy, catalog, // When added to this list, object types can be used as // { type: "typename" } in other document schemas productImage, blockContent, localeString, localeText, localeSlug, localeBlockContent, ]), }) 3️⃣ Add content to Sanity studio If you are working on a new project like we did when we began developing the starter, you will have to manually add content to your project using the Sanity studio running on . The studio should now have the content fields populated with the configured content schemas in the “Desk” view. You can use that to add content to your project, as seen in the screenshot below. [localhost:3333](http://localhost:3333) If you are starting a new project using a starter or a previously saved project, then you can easily import a dataset with saved data following the steps below: Extract the file in directory using the command below: production.tar.gz /.sanity-template/data tar -xf production.tar.gz The extracted folder name should look like . production-export-2021-02-26t14-15-56-557z Run the command below in to import the file in the extracted folder. /studio data.ndjson sanity dataset import ../.sanity-template/data/ /data.ndjson You should check the running Sanity studio now to preview the imported content. 4️⃣ Add frontend and integrate with Sanity Before you add all frontend code to the root directory, you should move the Sanity studio code into a directory named . /studio At this stage, you will add the frontend code of your project, which can either be a blog, marketing website, CRM, or storefront. The major thing to do here is to use any of the libraries to integrate Sanity into your frontend and fetch data. In our case, we used the official that works in Node.js and modern browsers. Sanity client Javascript client import sanityClient from '@sanity/client' const client = sanityClient({ projectId: process.env.SANITY_PROJECT_ID as string, dataset: process.env.SANITY_DATASET as string, useCdn: process.env.NODE_ENV === 'production', // `false` if you want to ensure fresh data }) Here’s an example of how we query Sanity to fetch the country and product data: import _ from 'lodash' import { SanityCountry, SanityProduct } from './typings' //Countries const sanityAllCountries = async (locale = 'en-US') => { const lang = parseLocale(locale, '_', '-', 'lowercase') const query = `*[_type == "country"]{ name, code, marketId, defaultLocale, "image": { "url": image.asset->url }, 'catalog': { 'id': catalog->_id } } | order(name["${lang}"] asc)` const countries = await client.fetch (query) return countries.map((country) => { const localization = { name: country?.name[lang], } return { ...country, ...localization } }) } //Products const sanityGetProduct = async (slug: string, locale = 'en-US') => { const lang = parseLocale(locale, '_', '-', 'lowercase') const query = `*[_type == "product" && slug["${lang}"].current == "${slug}"]{ name, description, reference, slug, 'images': images[]->{ 'url': images.asset->url }, 'variants': variants[]->{ label, code, name, size->, 'images': images[]->{ 'url': images.asset->url } } }` const item: any[] = await client.fetch(query) return parsingProduct(_.first(item), lang) } You can explore all our queries for the Commerce Layer starter project in the GitHub repository. Also, here’s the powering our frontend alongside some hooks, utils, components, and dependencies. here major code Now that you have a Sanity Starter set up, we’ll show you the foundation principles needed to integrate commerce data from Commerce Layer. This is where you will begin to see the powerful combination of Commerce Layer data with Sanity content. And by the end of the tutorial, you will see not only the benefits of this integration, but you will also be able to experiment with your commerce data next to Sanity to see the power of both tools together. 5️⃣ Get Commerce Layer API Credentials In the starter we built, transactional functionalities of your ecommerce platform are managed by Commerce Layer, while the content is managed by Sanity studio. This will result in better order management and content management. To get started with using Commerce Layer, you will need to create an organization, perform some configurations and settings for your business, seed some demo data, and get your API credentials. The API credentials will allow you to interact with Commerce Layer in your presentation layer (frontend) and the CLI. To get the required credentials, kindly follow the steps below: Create a free developer account . If you already have an account, kindly skip to Step 3. here Upon successful sign-up, skip the onboarding tutorial for the purposes of this article (we'll set up and seed the organization manually through the CLI shortly). Create a new for your business. organization In the Commerce Layer dashboard, click on the tab and create an application, with the name: . Upon successful creation, you'll get a , , and .

Integrations CLI Admin CLIENT ID CLIENT SECRET BASE ENDPOINT 6️⃣ Seed Organization with Test Data The official helps you to manage your Commerce Layer applications right from the terminal. Installing the CLI provides access to the command. You can set it up using the following steps: Commerce Layer CLI commercelayer Install the CLI using your favorite package manager: //npm npm install -g @commercelayer/cli //yarn yarn global add @commercelayer/cli Log into your application via the CLI using the previously created application credentials like so: integration commercelayer applications:login -o -i -s -a Now, with the steps below, you can use the CLI to import three demo (UK, USA, and Europe), a set of , related , related , , and into your organization using the multi_market . markets product SKUs price lists prices stock locations inventory business model Install the using the command below: seeder plugin commercelayer plugins:install seeder Seed your organization using the command below: commercelayer seed -b multi_market 7️⃣ Final checklist and Netlify deployment configuration In order for a starter to be validated and used through , it needs to follow the project name must start with . sanity.io/starters sanity-template- Configure your Sanity metadata in and add deployment configuration for the frontend web application and Sanity studio like so: sanity-template.json { "version": 2.0, "title": "Commerce Layer Starter", "description": "A multi-country ecommerce starter built with Sanity Studio, Commerce Layer, Next.js, and deployed to Netlify.", "previewMedia": { "type": "image", "src": ".sanity-template/assets/preview.jpg", "alt": "Preview image with Commerce Layer, Nextjs, and Netlify's logo" }, "technologies": [ { "id": "nextjs", "name": "Next.js", "url": "https://nextjs.org" }, { "id": "commercelayer", "name": "Commerce Layer", "url": "https://commercelayer.io" }, { "id": "netlify", "name": "Netlify", "url": "https://netlify.com" } ], "deployment": { "provider": "netlify", "sites": [ { "id": "studio", "type": "studio", "title": "Commerce Layer Starter Studio", "description": "A multi-country ecommerce starter built with Sanity Studio, Commerce Layer, Next.js, and deployed to Netlify.", "dir": "./studio", "previewMedia": { "type": "image", "src": ".sanity-template/assets/studio.png", "alt": "A preview image of the Sanity studio." }, "buildSettings": { "base": "studio", "dir": "/dist", "cmd": "npm run build" } }, { "id": "web", "type": "web", "title": "Commerce Layer Starter Web", "description": "A multi-country ecommerce starter built with Sanity Studio, Commerce Layer, Next.js, and deployed to Netlify.", "dir": "./web", "previewMedia": { "type": "image", "src": ".sanity-template/assets/preview.jpg", "alt": "A preview image of the web demo." }, "buildSettings": { "base": "/", "dir": "/out", "cmd": "npm run build" } } ] } } The metadata information is primarily displayed on as described below by the visual explainer from . sanity.io/create Sanity docs Test your file for errors using the sanity-template command: sanity-template.json sanity-template check Build your project with the configuration in using the command**:** sanity-template.json sanity-template build You need to refactor your project's , and in to a dynamic variable so when a user installs your starter via , Sanity can populate it with new values. To this, you pass the string value in as seen in the snippet below: name projectId dataset studio/sanity.json sanity.io/starters #> { "root": true, "project": { "name": " #>", "basePath": "/" }, "api": { "projectId": " #>", "dataset": " #>" } } You can also set up to automatically make and merge pull requests that bump the Sanity dependencies upgrades in . All you need to do is add a to the root directory, with the following configuration: Renovatebot studio/package.json renovate.json { "extends": [ "github>sanity-io/renovate-presets:sanity-template" ] } Run the command below to build the studio to a static bundle and deploy it to Sanity cloud on a URL. You can also deploy anytime you make any change to your studio. .sanity.studio sanity deploy PS: You can still host a studio on any cloud platform you choose too (here’s ) so you don't have to manually deploy after every change. how to deploy to Netlify Lastly, push your finished code to GitHub and test it live by ****deploying the starter on Sanity following the starter specification: https://www.sanity.io/create?template=[githubhandle]/sanity-template-[starter-name] Conclusion Now that you have built a Sanity starter and integrated Commerce Layer, you can start to add more items and product data stored in Commerce Layer so you can see how your products and prices show up within your content. The power of Commerce Layer is that you can really localize your commerce data to make it work for multiple markets, all of which likely have different prices, SKUs, promotions, and even simple things like item weights and measurements.
