I'm implementing In-App-Purchases in Expo, using RevenueCat.
Everything works fine in a build environment but in ExpoGo I get an exception if I import this library:
import Purchases, { PurchasesOffering } from 'react-native-purchases';
In my code I can detect when running in ExpoGo, so I would like to import this library only and if only running in NOT ExpoGo environment.
I tried this but is not working.
import { IsExpoGo, RevenueCatAPIKeys } from "./lib/constants";
if(!IsExpoGo){
import Purchases, { PurchasesOffering } from 'react-native-purchases';
}
Any clue?
can try something like this
const MODULE_NAME = !IsExpoGo ? require("react-native-purchases") : require("./lib/constants);
also take some help below link

I encounter the error 'Cannot access __fbBatchedBridgeConfig on web' when trying to run expo web
The instructions I got according to https://github.com/expo/fyi/blob/main/fb-batched-bridge-config-web.md was to do the following
Remove internal imports
You can remove the import altogether, or you can move an internal import inside of a platform specific block:
import getDevServer from "react-native/Libraries/Core/Devtools/getDevServer";
or
let getDevServer = () => { /* no-op */ }
if (Platform.OS !== 'web') {
getDevServer = require("react-native/Libraries/Core/Devtools/getDevServer");
+ }
However, I'm not sure where to insert this code. I've tried inserting it on my home page, on app.js, and I still encounter this error.
Could anyone help me out on this?
(I'm using EXPO 4.13.0, SDK 43 and react-native 0.64.3)
This error shows when you try to use a nested library from react-native.
Search specifically for react-native/ with your IDE in your project to find where you are importing such nested library.
There you can replace the offending import like:
import example from "react-native/example";
to:
let example = () => { /* no-op */ }
if (Platform.OS !== 'web') {
example= require("react-native/example");
}
You also need to import Platform like:
import { Platform } from 'react-native';
But note other errors might arise if you DO need to use that library, so also edit where you are using it.
I am a newbie in react-native and I'm trying to use the react-native-ui-kitten library. The problem is that the documentation is not really helpful.
I have I have installed ui-kitten and the theme as indicated with the command: npm i react-native-ui-kitten #eva-design/eva
The documentation asks to configure the application root which I consider to be the App.js file unless I'm wrong.
So i changed the App.js generated code to this:
import React from 'react';
import {
mapping,
theme,
} from '#eva-design/eva';
import { ApplicationProvider } from 'react-native-ui-kitten';
import { Application } from './path-to/root.component';
export default class App extends React.Component {
public render(): React.ReactNode {
return (
<ApplicationProvider
mapping={mapping}
theme={theme}>
<Application/>
</ApplicationProvider>
);
}
}
Unfortunetely it's not working.
Has anyone recently used ui-kitten library ?
What does the documentation mean by Application Root and how to set up a simple react-native project to use react-native-ui-kitten?
And yes I actually checked the documentation but maybe there is something I am not doing right.
I ran into the same problem.
I discovered that the creators of this UI kit use in fact in their code examples Typescript.
So you need to recreate your Reactnative project using a Typescript template, then rename accordingly the App.js into App.tsx
Any other components need to be renamed with the extension .tsx.
Make sure you read about Typescript:
https://www.typescriptlang.org
Here it is how you can recreate your project with Typescript:

All the best,
I am also a beginner in react-native and it seems we kinda differ in implementing the code. I am not sure if this would help but this is the way I implement your code:
import * as React from 'react';
import { mapping, light as lightTheme } from '#eva-design/eva';
import { ApplicationProvider } from 'react-native-ui-kitten';
import { Application } from './path-to/root.component';
const App = () => (
<ApplicationProvider
mapping={mapping}
theme={lightTheme}>
<Application/>
</ApplicationProvider>
);
export default App;
You could try it and let me know if this suits you. Good luck!
I am trying to use flow in my current react-native project. After some research, I discovered that all the types I need are in this file, but I have no idea how I am supposed to import these types.
For instance, I need to import the ViewLayoutEvent from there. What am I supposed to write in my file?
I tried the following:
import type { ViewLayoutEvent } from 'react-native';
import type { ViewLayoutEvent } from 'react-native/Libraries/Components/View/ViewPropTypes';
To no avail.
Update:
Or maybe it is in this file
Hell, I'm trying to create a tab bar in my react native app, but after importing it, it appears it's always undefined. Has this component been deprecated? I still see it listed in the docs. https://facebook.github.io/react-native/docs/tabbarios.html
import React, { Component } from 'react';
import {
TabBarIOS
} from 'react-native';
export default class App extends Component {
render() {
return (
<TabBarIOS/>
);
}
}
I'm using react-native 0.59.3
Looks like this has been removed as part of a core cleanup effort. There doesn't appear to be any native alternative that also behaves correctly on tvos.
https://github.com/facebook/react-native/commit/02697291ff41ddfac5b85d886e9cafa0261c8b98
I've gone ahead and extracted TabBarIOS out into a native module for anyone looking for this.
