all,
I am new to react native, I am now having issue when I was trying to use customize fonts for my application, it keeps giving me error: None of these files exist: * assets\fonts\ARIAL.TTF etc.
I appreciate if anyone can help me, thank you so much.
I am using expo to run my project, and I install expo-font(v 10.0.4) to use costomize font. Here is my code of using the fonts:
import { Provider } from 'react-redux'
import { PersistGate } from 'redux-persist/integration/react'
import AuthStack from './routes/authStack'
import store, { persistor } from './store'
import { useFonts } from 'expo-font'
import Loading from './components/loading'
function App() {
const [fontLoaded] = useFonts({
Arial: require('./assets/fonts/ARIAL.TTF'),
ArialBold: require('./assets/fonts/ARIALBD.TTF'),
BlairMd: require('./assets/fonts/BlairMdITCTTMediumFont.ttf'),
})
console.log('app font loaded====', fontLoaded)
return fontLoaded ? (
<Provider store={store}>
<PersistGate loading={null} persistor={persistor}>
<AuthStack />
</PersistGate>
</Provider>
) : (
<Loading />
)
}
So I am using useFonts hook from expo-font to load my fonts, and I already put my fonts file under assets, here is the file structure:
assets folder is under the same directory as App.js. In assets folder, there is fonts folder, and in fonts folder, all my fonts files are there
If anyone can help me, thank you so much
I had the same issue, it is resolved after stop and rerun the server.
I guess expo server needs to execute again in order changes to take place.

I am trying to use Google Fonts with my entire expo project, but i dont want to import it to each and every component. How can I just import it once, and call it everywhere? Or better yet, can I set my imported font as a default font?
app.js
import { Provider } from 'react-redux'
import store from './redux/store'
import { NavigationContainer } from '#react-navigation/native';
import { createNativeStackNavigator } from '#react-navigation/native-stack';
import { useFonts, Montserrat_400Regular,} from '#expo-google-fonts/montserrat';
import { HomeScreen } from './components/HomeScreen';
import { AddItemScreen } from './components/AddItemScreen';
import { DetailedDayView } from './components/DetailedDayView';
export default function App(navigation) {
const Stack = createNativeStackNavigator()
let [fontsLoaded] = useFonts({
Montserrat_400Regular,
});
if (!fontsLoaded) {
return null;
}
return (
<Provider store={store}>
{/* <SafeAreaProvider> */}
<NavigationContainer>
<Stack.Navigator>
<Stack.Screen
name="Home"
component={HomeScreen}
/>
<Stack.Screen
name="AddItemScreen"
component={AddItemScreen}
/>
<Stack.Screen
name="DetailedDayView"
component={DetailedDayView}
/>
</Stack.Navigator>
</NavigationContainer>
{/* </SafeAreaProvider> */}
</Provider>
);
}
For React Native CLI:
First of all, download any fonts in .ttf format.
Create a directory and name it assets, inside the assets directory create another directory name it fonts, and then move the .ttf file here. Your path will look like this: - root/assets/fonts/your-font.ttf
Now, in your root directory create a file named, react-native.config.js. Inside that file paste the following code:
module.exports = {
assets: ['./src/assets/fonts'],
}
Run this command npx react-native-asset. For the older version of React Native try this command npx react-native link
There you go. You're done. Now, check this directory root/android/app/src/main/assets/fonts to check if the font is added or not.
Now you can use your font anywhere in the app. Like this: -
fontFamily: 'your-font'
Note: You can add multiple font-family. For adding another font-family repeat 1, 2, and 4.
For Expo:
For Expo follow this answer: How to apply custom fonts to whole project, Expo React Native
I would like to load website from local file in my RN expo app.
My code is:
/* eslint-disable global-require */
import * as React from 'react';
import { WebView } from 'react-native-webview';
export default (): any => (
<WebView
source={require('./web/index.html')}
javaScriptEnabled
domStorageEnabled
originWhitelist={['*']}
allowFileAccess
allowUniversalAccessFromFileURLs
allowFileAccessFromFileURLs
mixedContentMode="always"
/>
);
During the run I am getting an error:
Error: 'web/style.css' cannot be loaded as its extension is not registered in assetExts
And styles doesnt works.
What is wrong?
This is my second go around installing tailwind rn for a project and I simply can't get it to work.
I ran npm install tailwind-rn followed by npx setup-tailwind-rn and I'm running it in development mode after changing the tailwind.config.js to scan the only app file:
content: ["./App.js"],
The App.js file in the meantime looks like this:
import React from 'react';
import { StatusBar } from 'expo-status-bar';
import { StyleSheet, Text, View } from 'react-native';
import {TailwindProvider} from 'tailwind-rn';
import utilities from './tailwind.json';
import { useTailwind } from 'tailwind-rn';
export default function App() {
const tw = useTailwind();
return (
<TailwindProvider utilities={utilities}>
<View>
<Text style={tw('text-blue-600')}>Hello world</Text>
<StatusBar style="auto" />
</View>
</TailwindProvider>
);
}
My tailwind.css and tailwind.json are both populated with defitions for .text-blue-600 and I receive no errors when running, but none of the styles I apply work. Very confused.
I would recommend using tailwind-react-native-classnames from jaredh159. No setup or extra configurations needed after installation. It works out of the box.
This package gives the flexibility of mixing styles.
Install using yarn add twrnc or npm install twrnc.

I need to show SVG icons inside my application, I did the entire process of installing the react-native-vector-icons library and configuring icomon. Also, I went to the icomon website and created my font files. But when I use it, the application renders an icon different from the one I should be reloaded by the file.
config icomon
import { createIconSetFromIcoMoon } from 'react-native-vector-icons';
import icoMoonConfig from '../../assets/customIcons/selection.json';
export default createIconSetFromIcoMoon(
icoMoonConfig,
);
icon that should be loaded.
icon being loaded
My code
export function ItemMenuDropdown({ item }) {
const navigation = useNavigation();
return (
<Container onPress={() => navigation.navigate(item.navigation)}>
<Content>
<CustomIcon name="pencil" size={normalize(18)} color="#F68B1F" />
<Text>{item.item}</Text>
</Content>
</Container>
)
I've looked for several solutions here on the site, but I haven't found one that works. Can someone help me?
I think the problem is in your selection.json file. It's either out of date or you're having some kind of cache problem. Maybe you want to try the same operation using this module.

I'm building a react native application with apollo client 3, and keep getting the following error when generating the javascript bundle.
Failed building JavaScript bundle.
Unable to resolve "./rules/FieldsOnCorrectType" from "node_modules/graphql/validation/index.js"
My code is pretty simple, this is App.tsx:
import { StatusBar } from 'expo-status-bar';
import React from 'react';
import { SafeAreaProvider } from 'react-native-safe-area-context';
import useCachedResources from './hooks/useCachedResources';
import useColorScheme from './hooks/useColorScheme';
import Navigation from './navigation';
import { ApolloClient, InMemoryCache, ApolloProvider } from '#apollo/client';
const client = new ApolloClient({
uri: 'localhost:4000/graphql',
cache: new InMemoryCache()
});
export default function App() {
const isLoadingComplete = useCachedResources();
const colorScheme = useColorScheme();
if (!isLoadingComplete) {
return null;
} else {
return (
<ApolloProvider client={client}>
<SafeAreaProvider>
<Navigation colorScheme={colorScheme} />
<StatusBar />
</SafeAreaProvider>
</ApolloProvider>
);
}
}
I've tracked it down to the instantiation of the new ApolloClient object - commenting out those lines (and the provider) causes the error to disappear.
Renaming node_modules/graphql/validation/rules/FieldsOnCorrectTypeRule.js to node_modules/graphql/validation/rules/FieldsOnCorrectType.js (dropping the Rule suffix of filename) fixes that specific error, but then errors on the next import in the validation/index.js file... I don't understand why.
I had the same problem with a react native app after upgrading to apollo client 3. For me it was a react native caching issue and the problem went away after following these instructions to clear the cache: How to clear react-native cache?.
I am using the react native cli and used these commands (I didn't check if all of them are actually necessary):
watchman watch-del-all
rm -rf /tmp/metro-cache
rm -rf node_modules
npm cache clean --force
npm install
npm start -- --reset-cache
If you are using the expo cli then apparently you can just do this:
expo start -c
