Typescript, Apollo Client and GraphQL Code Generator  -  A Love Triangle.

Typescript, Apollo Client and GraphQL Code Generator  -  A Love Triangle.

In this blog post, I have. Typescript, Apollo Client and GraphQL Code Generator  -  a love triangle. Since Shopify uses GraphQL — a query language and runtime system — for accessing its API, I thought that would be a good time to dive into learning GraphQL.

In the past 2 months I’ve been working on a storefront iOS app for a client’s store that’s build on the Shopify platform. Since Shopify uses GraphQL — a query language and runtime system — for accessing its API, I thought that would be a good time to dive into learning GraphQL. I have previous experience with REST and working with GraphQL has been nothing less than love at first sight. Being a huge fan of TypeScript I just love how everything is fully typed and part of a schema and also reachable through a single endpoint unlike REST where you’d have a different url for each part of data.

My client of choice has been Apollo Client v3 which integrates with React Native very smooth and provides easy hooks for operations as well as a global state management system through its cache and reactive variables or local only fields using the @client tag .

On the previous project I have worked on I’ve used Redux as the local state management and I really like the control flow and the logistics of Redux. Apollo has been a bit difficult to wrap my head around at start but after a while I started to enjoy using Apollo Client quite a bit more than Redux to be honest and that’s because of how Apollo stores data in the cache and only tries to get the data that it actually needs from the server when that data is not available in the memory cache — all of these can be configured using the cache policies. I also find reactivity and subscriptions to data in my components to be much more intuitive and easier to implement using Apollo with reactive variables.

How to Build Apollo GraphQL Server From Scratch

GraphQL is a query language and a server-side runtime that is used to request data from the server. The first thing that comes to mind when hearing the term “query language” is SQL. Just as SQL is used for querying databases, GraphQL is a bit like SQL but for querying web APIs as it eliminates the need to repeatedly develop or change existing end-points. GraphQL also enables the client/front-end to retrieve exactly the data they have requested and no more. This means that, within a single request of GraphQL, you can traverse from the entry point to the related data (whereas in RESTful API you have to call multiple endpoints to fetch similar results).
