What’s GraphQL? 

GraphQL is a question language for APIs created by Fb in 2012 that gives an intuitive and versatile syntax for requesting knowledge out of your Shopify retailer (or another service that helps the GraphQL schema). The Graphiql instrument, which makes working with this API a lot simpler, means that you can ship queries instantly out of your browser in opposition to any public endpoint of a GraphQL Schema. You need to use this instrument to check out all the completely different question operations accessible by means of the Storefront API to get a really feel for the way it works and what you are able to do with it.

GraphQL Schema:  The Storefront API is not only a single endpoint that returns particular knowledge, however somewhat a GraphQL schema that includes a number of completely different endpoints representing all the knowledge about your store and its merchandise. These endpoints are referred to as “sources” within the GraphQL world and every useful resource has a number of fields and strategies for querying and mutating knowledge. For instance, the Store object comprises many built-in sources equivalent to collections, pages, variants, and so forth… However you too can create your personal customized sources by offering further fields and strategies over prime of these included out of the field. Every time we use an endpoint from this schema to fetch knowledge in our app, we’re sending a GraphQL question to the Storefront API. These queries are made up of a number of fields that correspond to numerous useful resource fields and arguments for arguments equivalent to your access_token when calling an endpoint that requires authentication.

Graphiql: The Graphiql instrument means that you can ship queries instantly out of your browser in opposition to any public endpoint of a GraphQL Schema. As soon as put in, it offers autocomplete options for all built-in sources and offers an outline of every area accessible on the useful resource together with an instance request and response. This allows you to simply construct out advanced requests even should you aren’t conversant in the syntax of the graphql language. You may as well use this instrument to debug any app you’ve constructed utilizing the Storefront API. It reveals you all the requests being despatched to the GraphQL endpoint, their responses, and any errors which have occured.

Getting Began

You’ll be able to construct your personal Shopify apps from scratch or begin with an current app constructed on React Native which can run within the JavaScript runtime offered by NodeJS. If you happen to select to begin with an current codebase, merely obtain it onto your laptop and comply with together with this information so that you simply perceive the movement of knowledge required to get it up and operating in your Shopify retailer!

Creating Your App’s Schema [to explain initial steps before building out schema] You’ll then have to create a GraphQL schema within the Shopify Companions Dashboard and add this to your app’s bundle.json file. This may can help you import the schema into your personal codebase and ship queries in opposition to it when constructing out your app’s UI (Consumer Interface). You’ll additionally have to guarantee that the access_token area is current on any object in your schema that wants authentication, equivalent to when querying consumer knowledge or calling store strategies.

Creating Your App: Now that you’ve got an thought of what’s doable with the Storefront API, let’s create our personal model of the Shopify POS which can be utilized by clients who go to our brick and mortar retailer to buy product. The very first thing we’ll have to do is create our app on the Shopify Companions Dashboard, which can permit us to generate an OAuth token that’s required for utilizing the Storefront API.

Displaying Product Catalogs: Now that you simply’ve created your GraphQL schema and added your access_token area to any sources you plan on querying, it’s time for some coding! For this step, we will likely be making a easy React Native undertaking with two screens: one the place customers can choose merchandise from numerous collections by querying the store object, and one other for choosing product variants (together with shade/dimension choices).
