I would like to create a repo for a Library for UI Components thats reusable in multiple react native projects. I want to use NativeWind (tailwind for react native)
Can anyone give me any tips on how I would go about doing this? I have tried setting up a library with nativewind installed.
But when I create a component styled using nativewind, then try to run an example of using said component it doesn't show any of the styling.
I used react-native-builder-bob for boilerplate library.
I am a beginner with React Native.
I'm using Expo on Windows 10 and testing on an iPhone.
I need to create a map with custom tiles.
After some research I find out that Leaflet is not React Native compatible so I have to use react-native-maps.
I install it and create my first basic map, so far so good (Apple Maps).
Then I tried to apply the custom tiles. For performance reasons I want to use local tiles. Here came the question of how to get the local link of my tiles (located in "assets/tiles").
While searching I realize that I need to use react-native-fs to use the following path file://${RNFS.DocumentDirectoryPath}.
I install it.
However, when I try to add react-native-fs using
var RNFS = require('react-native-fs');
I get the error :
Invariant Violation: Native module cannot be null.
and I'm lost and don't know if I'm going the right way.
Thanks
I built an application in React, is there a way that the same code will be used for a website?
I know Instagram is built on React and it also has a website, I wonder maybe you should add some link or something that it will open for me as a website?
Or maybe there is no such way and I have to build a website separately?
First off all, If you have written any code which is related to native functionality, then it can be challenging.
If you have only worked with views, images, and some of the basic functionality.
It can be done with react-native-web you can easily migrate your project to react-native-web.
If you project is created with expo they already provide react-native-web support.
Option 2: If you have some of the code you want to share and some is that you don't want to share or can't share.
You can use renderProp or customHooks pattern to reuse your logical code and seperate your view for react-native and react js apps.
If you want to reuse your views too, you can do those with primitives.
you can use styled-component primitives for that.

You can get some idea here as well.
I am not able to use google.maps.geometry.poly.isLocationOnEdge() in my react native project. Is there any other way to check whether a point lies on a route which I can use to react native?
I recently came across this problem while using react-native-maps.
You can use isPointInLine(point, lineStart, lineEnd) method by using geolib JS package. This package has many other useful methods.
I'm trying to understand how I can do a signature capture in React Native. My App is created with create-react-native-app and Expo and I'd prefer to not have to eject the app to get this functionality to work.
Would it be possible to wrap something like this in a webview? https://github.com/szimek/signature_pad
I've also looked at this project, https://github.com/RepairShopr/react-native-signature-capture but it requires me to eject the app and use react-native link.
Looking for any advice or suggestions on how to implement this feature while keeping my project as straightforward as possible (ideally, using create-react-native-app, but if this isn't possible could someone please explain to me why?)
The way React Native works is that each component available in React Native maps to a native component in the underlying platform.
ie. a <Image /> is an ImageView in Android and a UIImageView.h in iOS.
The Javascript code itself runs in a Javascript thread on each platform and as you use Components in React Native, there's a translation layer that passes information from JS into the React Native bridge that then results in corresponding native components being created.
By default, React Native has included the following components: https://facebook.github.io/react-native/docs/components-and-apis.html#basic-components which means that only those components come out-of-the-box in React Native. If you want other components, then you have 2 options, either create a "composite" component in which your JS component is written into other JS components or, if your feature needs a native component not yet exposed by React Native, write your own "native" component to expose certain native functionality to your React Native code.
The way Expo works is that they have wrapped React Native and a handful of 3rd party components and built it within their application. The reason why you can't use a 3rd party native component they don't support is because when that component is used, the app itself doesn't have translation code to go from JS to a native Android/iOS view.
So, to do what you're asking, you'd need to find either a "native" drawing component that Expo has included in their platform/app. OR you need to find a "composite" drawing component that is built with other default React Native components (or other components Expo supports).
ie. On Android, I might build this with a Canvas view, but from what I can tell React Native doesn't support that object natively, so I would probably write this myself, etc.
It's hard for Expo to support every 3rd party "native" component out there because React Native is open source and it iterates so fast that most community-built components aren't always up to date or they might conflict with one another.
I am using react-native-signature-capture.
Working properly on both Android and iOS.
I know it's been a while, but there is an interesting article here: https://blog.expo.io/drawing-signatures-with-expo-25d1629ca1ac
Wait, but how?
Using “expo-pixi”, you can add a component that lets you choose your brush’s color, thickness, and opacity. Then when your user lifts her finger, you get a callback. From there you can take a screenshot of the transparent view or get the raw point data if that’s what you’re looking for.
