Keeping data on mobile devices secure is crucial if you’re working on a product that stores sensitive information about your user.
But did you know that by default, the local storage mechanism in React Native (AsyncStorage) is unencrypted?
On iOS, the main storage library for React Native is based on the Apple File System, using
FileManager to read and store files on the device unencrypted.
TL;DR — just show me the code!
I usually write about technical topics, but I want to use this opportunity to share the journey of a project I’ve been working on for the last year with my spouse and business partner Andreea Apetrei Kalveram.
In a nutshell, The Sustainable List is a curated list of sustainable fashion brands. Our goal is to help consumers navigate the ever-growing sustainable marketplace and give more visibility to brands that are socially and environmentally responsible.

One of the biggest troubles I often come across when building mobile apps in React Native isn’t necessarily technical: it’s that people design iOS apps for Android, or vice-versa.
Many companies choose React Native over native development because of its shallow learning curve. But what often falls by the sideway is that you’re still developing for two entirely different environments.
We should craft a user experience that follows each platform’s respective design guidelines.
Lately, I’ve been working on integrating a GDPR opt-out feature into an app. This feature allows users to flip a switch to decide whether they want any privacy-related data to be tracked by our app or any of its third-party dependencies.
From a legal standpoint, that’s an interesting challenge, because if you could at any point use any of the tracked data to re-identify a person to which the data refers, it means that it has not been effectively anonymized, thus you’re not complying with the GDPR guidelines.
From a technical point of view, that means you have to completely…
Upgrading is one of those tedious tasks that you’ll inevitably face at some point when working on a React Native project. If you’ve ever gone through this process, you’ve probably realised that it still has a lot of potential for improvement.
The most popular complaint about React Native, according to the recent “What do you dislike about React Native?” thread on GitHub is indeed: upgrading. It received 569 thumbs-up from the community, the second being Debugging with 350.
There’s been a very popular article on Upgrading React Native about 2 years ago, when it was at version 0.45. Since React…
Recently I’ve helped a client migrate their e-commerce front-end from a native wrapper app to React Native.
Since a big part of the team didn’t have any previous experience with React, it was natural that we’d run into a lot of inconsistencies in the beginning. My job was to help iron these out and lay the groundwork for a more maintainable codebase.
One of the challenges was to understand and organise the building blocks of the UI layer. …
