Using GraphQL Code Generator with Apollo-Server and TypeScript

GraphQL Code Generator can change the way you write GraphQL code going forward. Let’s see how easy it can be to get up and running with it by setting up a TypeScript based GraphQL server in Apollo.

GraphQL Code Generator is honestly a game-changer for writing GraphQL based code (both server and client-side). In this article, we will be learning how to leverage GraphQL Code Generator from within Apollo. In this article, we will use it by generating the types for our resolvers, enabling us to write type-safe resolvers with minimal effort.

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

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.

Interacting With GraphQL APIs Using TypeScript, React Hooks, and Apollo.

GraphQL is an open-source web-API language for reading(querying) and writing(mutating) data developed and maintained by the engineers at Facebook. You might be wondering… why GraphQL? Well, It allows specific data to be returned and allows fetching data from multiple areas all in a single request.

A quick background check shows that GraphQL has:

• Over 4,000,000 weekly downloads.
• Over 7,000 dependent packages.
• Over 116 releases to date.
• Over 16,000 stars on GitHub.
• And it has been around for close to 5 years now since it’s public release.

GraphQL has recently gained popularity over REST mainly because:

• With REST, gathering a good amount of information would typically involve accessing multiple endpoints which isn’t the same GraphQL, you’d only be required to make one query with your requirements and the server would respond with a JSON object fulfilling all your requirements.
• Over fetching or under fetching of data. With REST, it’s very hard to design an endpoint that will return just data the client will need. Say you want to get users names from a REST API, you’ll probably hit the /users endpoint that will retrieve so much more information about the users like age or sex that isn’t necessarily needed by the client at that point.
• GraphQL has the benefits of a schema and type system. It uses a strong type system to define the capabilities of an API.
