Creating custom universal native modules for your Expo bare workflow apps - Part 1

TODO: Make an awesome introduction. The one below is a draft

You love Expo. But sometimes you have to add some native code. With Expo Unimodules you can make your custom native code reusable between any Expo app, and with a little more effort, between any React Native app. What's more - the native code will be loaded automatically when you do yarn install, without the need of any additional linking. And in this article I'll show you how to.

I assume you are using Mac - however it's not necessary unless you follow the iOS part. Also, some terminal commands I use are Mac-specific.

What are unimodules?

A simple GraphQL Query Builder experiment.

graphql folder structure

• __tests__
• queries - Domain specific Query API, e.g. UserQuery
• mutations - Same as above, but mutations.
• types - TypeScript interfaces directly corresponding to GQL schema types, e.g. User. Can be generated typedefs also
• GraphqlClient.ts - GraphQL client + error handling. Can be any client, I use @urlq/core here.
• QueryBuilder.ts - Query Builder implementation and some TypeScript magic
