How to Build an iMessage Extension for a React Native App (Part 1)

I will show you how we built an iMessage extension by writing a bridge for our React Native-based mobile app. This approach took our team around two weeks to explore and might save you significant time if you have a similar intention. This is part one out of two of the walkthrough.

When we set out to build an iMessage extension for Lisk Mobile using React Native, we immediately hit an exciting challenge. As it turns out, when it comes to third-party applications, Apple likes developers to play by their own rules. If a company wants to benefit from the tech giant’s operational systems and rich user base, it needs to be built using Apple’s own tools and programming language. iPhone’s iMessage is definitely worth this hassle. It has proven to be a big hit since its release in 2016. Within the first six months, iMessage has generated thousands of innovative in-messenger extensions, including those created by Airbnb and Dropbox. Late in 2018, Mark Zuckerberg admitted this feature is one of Facebook’s ‘biggest competitor by far.’ Since the release of Lisk Mobile during Lisk’s Berlin meetup in October 2018, our team has been busy implementing features such as Face ID Authentication, as well as developing blockchain-specific solutions. Identifying the opportunity to extend the iMessage option for our users, we got to work on our own integration.
The iMessage extension was included in Lisk Mobile 0.10.0, which was released in February 2019. Our users can now request and send LSK tokens straight from the iOS-based messenger without opening our app. However, the journey to implement this feature wasn’t straightforward. Lisk Mobile is written in JavaScript using React Native, while iMessage requires development in native iOS. During our research, we have found there is just a handful of resources available to help with using React Native to build iOS extensions available out there. There was no clear way to proceed. After thorough deliberation, we have decided to try a different approach by building our own bridge implementation. We found it a very educational and motivational journey for our team to develop the feature in this way. We will show you how, by breaking the solution down into native and React Native parts, and describing how to bind these separated parts together.
