UPDATE:
react-navigation web support is done. follow this:
https://reactnavigation.org/docs/en/web-support.html
ORIGIN:
I try to share my code between react-native and web.
when I try react-native-web, it works well.
but there is only one question, how to access the specific screen from URL?
I read the react-navigation docs, there nothing about that.
and react-router-native can catch the web URL,
but it has navigator likes StackNavigator/DrawerNavigator.
and idea about that?
I'm not sure what the case was at the time you posted this question, but you definitely can use react-navigation with web now adays.
Now with Linking we can Handle deep links in React Native apps on Android and iOS, plus
Enable URL integration in browser when using on web.
The NavigationContainer component takes in a linking prop which allows you to map out your routes.
const linking = {
prefixes: ['https://mychat.com', 'mychat://'],
config: {
screens: {
Chat: 'feed/:sort',
Profile: 'user',
},
},
};
function App() {
return (
<NavigationContainer linking={linking} fallback={<Text>Loading...</Text>}>
{/* content */}
</NavigationContainer>
);
}
Once we establish what all of the routes or "links" are in our app we can start using Link components to navigate just like in a normal react web application if you used react-router-dom.
import { Link } from '#react-navigation/native';
// ...
function Home() {
return <Link to="/profile/jane">Go to Jane's profile</Link>;
}
These link components should work on both mobile, and web versions.
https://reactnavigation.org/docs/configuring-links/
https://reactnavigation.org/docs/deep-linking/
https://reactnavigation.org/docs/link
I don't think it's possible as ReactNavigation is using an internal state object. Remember, it's mobile framework, it has no concept of URL routing.
I also wanted to point out that even though RN claims web support you will need to be careful with component selection as not all the behaviours are identical (from memory, FlatList does not support touch scroll)

I have a Component that renders a Webview, of which there are links. For example, if I have something like:
export const About = () => {
return (
<SafeAreaView edges={['right', 'top', 'left']} style={{ flex: 1 }}>
<Webview url={`${BASE_URL}/about`} />
</SafeAreaView>
)
}
export default About
Let's say that on the /about page, we have a link to /faq. As things currently stand, if I click on the link to /faq, the page will be rendered in that current Webview.
My desired behavior is for the /faq to put on the navigation stack so I can take advantage of the back button in the header. I don't know how to accomplish this. I don't have access to the link to /faq via React Native (see code snippet above) so I can't just add an onClick that pushes a page to the stack.
Another thing I was exploring was setting up some linking configurations so I can link /faq to /about, and so the routing would recognize that. No idea if I was going down a good path there. Please forgive me if I've mixed up concepts, my understanding of the React Native ecosystem and React Navigation is still very raw. Thank you for your time.
using some basic code, I am trying to access a sharepoint page:
import { WebView } from 'react-native-webview'
const ExampleScreen = ({ navigation }) => {
return (
<WebView style={{flex: 1}}
source={{uri: 'https://example.intra.net/sites/1/ProjectName/SitePages/Nameofpage.aspx'}}/>
)
}
export default ExampleScreen;
When I pull up the page on Safari, I can see it, because I'm logged in. However when I try to look at the page in the Expo Go test build, it says "401 Unauthorized". What is the process for authenticating something like this in a native app? I am a novice and I don't understand how it works.
After using Linking.getInitialURL() the URL stay there.
I am using react-native-router-flux to navigate.
when users log out I run
import { NativeModules } from 'react-native';
NativeModules.DevSettings.reload()
What happens is the react-navigation do Linking.getInitialURL()
and if there any result so it navigates automatically to the page.
how to reset Linking.getInitialURL() after use ?
happens only on android
React Navigation 5 provides an option to specify a custom getInitialURL method which you can use:
<NavigationContainer
linking={{
// ... linking config
getInitialURL() {
return YourCustomModule.getInitialURL();
},
}}
>
{/* content */}
</NavigationContainer>
https://reactnavigation.org/docs/navigation-container/#linkinggetinitialurl
For the implementation, since you're reloading the whole JS, the code cannot be in JS as the state is lost on reload. You'll need to write a custom native module where you can clear the initial URL when reloading.
import React from "react";
import AppLoading from "expo-app-loading";
export default function App() {
return <AppLoading />;
}
Isn't the above code supposed to show the splash screen to me? All I get is a white screen. Would really appreciate knowing what I did wrong here.
I have splash.png in my assets folder.
My app.json file:
{
"expo": {
...
"splash": {
"image": "./assets/splash.png",
"resizeMode": "contain",
"backgroundColor": "#e2fcff"
},
...
}
}
The code you have shown looks fine. However, there's more to it.
It's quite unclear to me what is actually supposed to work and not. For me, who runs a custom-managed workflow, AppLoading works when I prebuild android/ios and run the standalone app. When I run in Expo Go app I simply see a blank screen instead of the splash screen.
People have discussed if AppLoading works in bare workflow and according to Expo's sdk it should. It also works for me with a prebuild, so bare workflow is supported (in Expo SDK 42).
I have seen no mentions about showing a splash screen within the Expo Go app though, so can't tell whether that is supported or not.
And then web... Once again, not sure if it should work or not - it doesn't for me. It shows a blank page while loading. And in the fonts guide there is an Expo snack which uses AppLoading that shows a splash screen on Android but merely a blank page on web. The AppLoading docs claims it has support for web. If that means it won't crash, or actually display a splash screen image is left untold. The AppLoading docs further claims it uses SplashScreen to show the splash screen, which doesn't have web support. So, I suppose there's nothing such a splash screen for web (which wouldn't surprise me, because splash screens are uncommon on web).
Personally, I'm fine with Android/iOS support for standalone apps. I only use Expo Go for testing. Furthermore, the splash screen I will use for mobile devices won't work well on web anyway. The skeleton I will show won't look the same as the web version, so I would rather implement at custom splash screen for web.
Summary for AppLoading support:
Managed and bare workflow are both supported.
It works on standalone apps.
Not sure if it will display the splash screen in Expo Go app.
Web appears to fallback to displaying a blank page.
If I'm wrong somewhere, or if someone knows if AppLoading works in Expo Go App, please fill me in!
App loading documentation In the documentation, it says that you need to provide additional arrugments
export default function App() {
const [isLoading, setLoading] = useState(true);
if (isLoading) {
return(
<AppLoading
startAsync={() => console.log('starting')}
onFinish={() => { setTimeout(() => {setLoading(false)}, 1000) }}
onError={(err) => {console.log(err)}}
/>
)
}
return (
<View style={styles.container}>
<Text>Open up App.js to start working on your app!</Text>
</View>
);
}
How to make https://xr-spinosaurus.glitch.me/ work in a React Native WebView Component?
import React, { Component } from 'react';
import { WebView } from 'react-native';
export default class MyWeb extends Component {
render() {
return (
<WebView
source={{uri: 'https://xr-spinosaurus.glitch.me/'}}
style={{marginTop: 20}}
/>
);
}
}
Right now adding this to react-native only shows VR option but not AR option.
If you access the link directly you could see VR and AR options but I couldn't find the AR option when run in a Web View component inside React-Native
But the same AR option is available if I directly access the link on an ARCore supported Device.
How to make this code also show the AR option in React-Native?
AFAIK that is currently not possible, since the Android WebView doesn't (yet) support the WebXR Device API (and neither on apple). Source: https://developer.mozilla.org/en-US/docs/Web/API/WebXR_Device_API
I've been running into the same problem, hopefully support will be added soon, but for now there's not much you can do.
