When you're developing a React Native app, it's easy to forget the different ways and conditions your users can be experiencing it.

For instance, what happens when there's no internet connection?

If you haven't asked yourself this then the answer is... absolutely nothing 😭

When your users click around, they'll be stopped in their tracks by spinners and loading pages. They aren't receiving any errors so they sit there, waiting...

Until they close and delete your app to never open it again because it's broken.

But your app isn't broken, you just need to have a plan for when the internet goes down.

It's not just that the network connection is on or off— there are actually three levels of offline support:

  • Only show errors when offline
  • Read-only offline support
  • Sync-later offline support

Course Project

You will incrementally build out a news application displaying a list of stories, story pages, and a bookmarks page.

As you start, you'll learn how to query data for the application using GraphQL and import and call those queries in the components that need the data.

This project also uses TypeScript but the way it is used is fairly unique. You'll see how we can have the safety of TypeScript in our app without having to write any types ourselves. Using the GraphQL schema that powers the data for your application, you'll generate TypeScript types almost for free with a code generation.

By the end of this course, you'll learn how to implement the first two levels of offline support and have the knowledge to implement the last level after this.

Skills you'll learn

  • Fetch and use GraphQL data
  • Generate types based on GraphQL schemas
  • Add navigation in React Native
  • Display errors when there is no network connection
  • Cache data for offline viewing in a React Native app

Get Started:

The videos are recorded on a Mac with an iPhone 13 Simulator using plain React Native, but you can do this course using Android, Windows and even the Expo managed workflow. See the lesson description for platform-specific instructions. The solutions repo has been verified to work on a Pixel 3a Emulator on Mac.

The completed app for this course is available here and each lesson will include a link to the commit that added the code so you can check your work.

This course will require you to run the API locally on your device. The API repo is available here.

What's Next

After this course, you'll be able to apply this offline-first pattern to any app that you're building.

If you're looking for a deep dive on building a React Native app, you can follow along with Chris Achard and build a Restaurant Review app. This would be a great opportunity to implement offline support in another context.

In the theme of building quality user experiences for your native applications, Kadi has produced a course teaching you how to implement a skeleton loader (vs just showing a spinner). You'll learn how to display a static version of the content you want to show users.

    What did you like about this course?

    The course is very informative and gave a good insight on how to use urql in the client. Plus points for showing how to work with the cache and offline capabilities. The only thing I didnt like that much was the last chapter. The instructor went to quickly without explaining in more details what does things actually do.

    What did you like about this course?

    There was a lot to take away from this course. I loved how Kadi started with implementing all the GraphQL queries for the application then referenced those throughout the course. Also, generating TypeScript types from your GraphQL schema is a new concept to me but makes so much sense!
