We are building a shared UI platform for one of our clients where we decided to store the code in a monorepo and use nx.dev to help us with the code organisation, dependencies, builds, etc. When trying to set up the common libraries of the project as publishable (and buildable) libs, we run into compilation… Continue reading NX.dev – Problems with buildable libraries.

Grafana Panel Not Refreshing in Real-time (sometimes)
For one of our clients, we’re using Grafana to display charts for the device data. These charts (panels) are embedded in a React app as iframes. Recently we noticed a strange issue with one of the embedded charts. The bar chart values were updated, but not their colouring. If one would reload the iframe URL,… Continue reading Grafana Panel Not Refreshing in Real-time (sometimes)
In a React app, I need to press the back button 2 times in order to go to the previous page
In case you have such an issue, and verify that you don’t call history.push() 2 times, check your content for an iframe. TL; DR: React tries to minimize re-rendering and will reuse the iframe element by just changing its src. This will update the history object, which is apparently shared with the main page (and… Continue reading In a React app, I need to press the back button 2 times in order to go to the previous page
React Drag And Drop not working with AnyDesk
We had a very strange issue with a project we work on. Our React app supports drag-and-drop of devices on a floorplan, using react-dnd. Everything works just fine locally and on our servers, but once the UI is deployed to the production machine (that is accessible via intranet), the drag-and-drop stopped working. Debugging the production… Continue reading React Drag And Drop not working with AnyDesk
React Native Shadow is Missing on iOS but is Okay on Android
In one of our projects, some of the items that had a shadow, was working just fine on Android, but the shadow was missing on iOS. After investigating it, it turned out to be related to the items that had overflow: ‘hidden’, which on iOS resulted in shadow being trimmed. Turns out on iOS, the… Continue reading React Native Shadow is Missing on iOS but is Okay on Android
SentryError: Native Client is not available, can’t start on native when updating expo-cli to 4.x.x (from version 3.22.3)
TL;DR: Update your metro.config.js to use @expo/metro-config based on the latest guidelines (SDK 40+) – It’s funny when you encounter an error in a project, and after spending a lot of effort researching it, to find out that the cause is the same with a totally different error on a very different project. In my… Continue reading SentryError: Native Client is not available, can’t start on native when updating expo-cli to 4.x.x (from version 3.22.3)
ValidationError: “devClient” is not allowed (while using expo and react native)
I ended up getting this error after an unsuccessful attempt to update the expo-cli. The solution was to delete the .expo folder from the project. Good luck! : )
Icons Not Loaded After Updating ReactNative Expo to Version 40
TL; DR: If you’re loading SVGs, check into your metro.config.js and see if you’re using the getDefaultConfig from ‘@expo/metro-config’. If you’re requiring it from ‘metro-config’, you should update your code based on the one below. More info in the readme of ‘react-native-svg-transformer‘ Recently I’ve had an issue with updating a project I was working on… Continue reading Icons Not Loaded After Updating ReactNative Expo to Version 40
Messing with Expo Permissions caused ImagePicker to misbehave
Have you seen the following alert? Sorry, we need media library permissions to make this work! Well.. me too! 🙂 And I’ve seen this error despite the fact that I’ve had both the “CAMERA” and “MEDIA_LIBRARY” permissions added to my android.permissions array. Googling didn’t help much, because it just led me to either the expo… Continue reading Messing with Expo Permissions caused ImagePicker to misbehave
Updating a React Native/Expo image file does not update the visualization of this image everywhere in the app
I’ve had an interesting problem when saving and updating images in a React Native application built with Expo. I’m building an app that has contacts and images (that are either taken from the phone contact entry or picked from the gallery). The issue was that editing the image at one place and saving it, would… Continue reading Updating a React Native/Expo image file does not update the visualization of this image everywhere in the app
