React Native Algolia Instant Search & SearchBox - reactjs

When following the Algolia docs (https://www.algolia.com/doc/api-reference/widgets/react/) to setup a simple search of the Alogila index with the following code
import React, {Component} from 'react';
import ReactDOM from 'react-dom';
import {Text, View, StyleSheet, Button, TextInput} from 'react-native';
import algoliasearch from 'algoliasearch/lite';
import { InstantSearch, Index, SearchBox, Hits } from 'react-instantsearch-dom';
const searchClient = algoliasearch(
'**********', //app ID
'************************' //app key
);
class MyApp extends Component {
constructor(props){
super(props);
}
render(){
return (
<View style={{
flex: 1,
alignItems: "center",
flexDirection: "column",
paddingTop: 20
}}>
<InstantSearch
searchClient={searchClient}
indexName="dev_INVENTORY">
<SearchBox/>
</InstantSearch>
</View>
)}
};
const styles = StyleSheet.create({});
export default MyApp;
I get the error 'Invariant Violation: View config not found for name input. Make sure to start component names with a capital letter.
This error is located at in input (created by Searchbox)....'
When I remove the SearchBox code the app functions fine but as soon as I add it i come across the error, but clearly all the elements are capitalized correctly (unless i've made a ridiculous silly oversight!?)
I wondered if the error was related to this persons issue;
Using Algolia react-instantsearch with react-native but i dont think it is.
If anyone has any suggestions just so I can get started with searching Algolia that would be ace as I'm a bit stuck!

The issue is that you're trying to use some widgets from react-instantsearch-dom which are not compatible with React Native.
For React Native you'll need to use the connectors instead of the widgets: https://www.algolia.com/doc/guides/building-search-ui/going-further/native/react/#using-connectors-instead-of-widgets
In your case it should give you something like:
import React, { Component } from 'react';
import PropTypes from 'prop-types';
import { View, StyleSheet, TextInput } from 'react-native';
import algoliasearch from 'algoliasearch/lite';
import { InstantSearch, connectSearchBox } from 'react-instantsearch-native';
const searchClient = algoliasearch(
'**********', // app ID
'************************' // app key
);
class SearchBox extends Component {
render() {
return (
<View>
<TextInput
onChangeText={text => this.props.refine(text)}
value={this.props.currentRefinement}
placeholder={'Search a product...'}
clearButtonMode={'always'}
spellCheck={false}
autoCorrect={false}
autoCapitalize={'none'}
/>
</View>
);
}
}
SearchBox.propTypes = {
refine: PropTypes.func.isRequired,
currentRefinement: PropTypes.string,
};
const ConnectedSearchBox = connectSearchBox(SearchBox);
class MyApp extends Component {
constructor(props) {
super(props);
}
render() {
return (
<View
style={{
flex: 1,
alignItems: 'center',
flexDirection: 'column',
paddingTop: 20,
}}
>
<InstantSearch searchClient={searchClient} indexName="dev_INVENTORY">
<ConnectedSearchBox />
</InstantSearch>
</View>
);
}
}
const styles = StyleSheet.create({});
export default MyApp;

Can’t find variable navigation in react native expo

Before I begin, I'd like to say that there were other questions that were answered that had a similar problem but none of those solutions worked for me. I just started using React Native Expo today and I'm finding the navigation part a little difficult. Take a look at the code:
App.js
import React, { Component } from 'react';
import HomePage from './HomePage'
import DetailsPage from './DetailsPage'
import { NavigationContainer } from '#react-navigation/native';
import { createStackNavigator } from '#react-navigation/stack';
const Stack = createStackNavigator();
function App() {
return (
<NavigationContainer>
<Stack.Navigator>
<Stack.Screen name="HomePage" component={HomePage} />
<Stack.Screen name="DetailsPage" component={DetailsPage} />
</Stack.Navigator>
</NavigationContainer>
);
}
export default App;
I've got 2 .js files that represent 2 pages of my app, here's the code for those files:
HomePage.js
import React, { useState } from 'react';
import { StyleSheet, Text, View, SafeAreaView, FlatList, TouchableOpacity } from 'react-native';
export default function HomePage() {
// Create a temporary list to populate the table view
const [orders, setOrders] = useState([
{ company: 'Airbnb', date: '20/02/2020', author: 'Mohammed Ajmal', itemOrdered: 'Sack Craft paper', id: '1' },
{ company: 'Apple', date: '15/01/2020', author: 'Ilma Ajmal', itemOrdered: 'Multiwall paper sacks', id: '2' },
{ company: 'Google', date: '30/12/2019', author: 'Rifka Ajmal', itemOrdered: 'Rigid paper sacks', id: '3' },
{ company: 'Facebook', date: '29/06/2020', author: 'Fahim Khalideen', itemOrdered: 'Paper bags', id: '4' },
])
return (
<View style={styles.container}>
<SafeAreaView>
{/* Create the table view */}
<FlatList
style = {styles.tableView}
data = {orders}
keyExtractor = {(item) => item.id}
renderItem = {({ item }) => (
<TouchableOpacity style = {styles.tableViewItem} onPress = {() => {
navigation.navigate('DetailsPage')
}}>
<Text style = {styles.companyName}>{ item.company }</Text>
<Text style = {styles.date}>{ item.date } | { item.author }</Text>
<Text style = {styles.itemOrdered}>{ item.itemOrdered }</Text>
</TouchableOpacity>
)}
/>
</SafeAreaView>
</View>
);
}
// Stylesheet
DetailsPage.js
import { StatusBar } from 'expo-status-bar';
import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
export default function DetailsPage() {
return (
<View style={styles.container}>
<Text>Open up App.js to start working on your app!</Text>
<StatusBar style="auto" />
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#fff',
alignItems: 'center',
justifyContent: 'center',
},
});
What I'm trying to create is a table view, when clicked, it should take the user to the Details page, but I'm getting an error saying
Can't find variable: navigation
I tried almost everything I could find in Stack Overflow but nothing helped me, maybe because the code in those answers were different and I couldn't understand how to make it work for mine.
You are not having a parameter for the navigation change the
line
export default function HomePage() {
to
export default function HomePage({navigation}) {
And it will work.
Or you could make use of the withNavigation when using a class component.
import { withNavigation } from 'react-navigation';
class DetailsPage extends React.Component {
render() {
return (
<View style={styles.container}>
<Text>Open up App.js to start working on your app!</Text>
<StatusBar style="auto" />
</View>
);
}
}
export default withNavigation(DetailsPage);

View config not found for name div

Card component from shards-react isn't working
When I run react-native run-android I get an Error:
View config not found for name div.Help please thanks.
import React from "react";
import PropTypes from "prop-types";
import { StyleSheet, Text, View, Alert, Image } from 'react-native';
import { Card } from "shards-react";
class User extends React.Component {
render() {
const { name, avatar, email} = this.props;
const userDetails = (
<View>
<Image style={styles.img} source={require('../assets/logo.jpg')} />
<Text>Name: {name} </Text>
<Text>Email: {email} </Text>
</View>
);
return (
<Card>
{userDetails}
</Card>
);
}
}
const styles = StyleSheet.create({
img:{
marginTop:250,
height:120,
width: 120,
borderRadius: 70,
}
});
User.propTypes = {
name: PropTypes.string,
avatar: PropTypes.string,
email: PropTypes.string,
isLoading: PropTypes.bool
};
export default User;
Is this library work only for web ? Not for mobile apps ?
If yes is there another one ?
shards-react by default uses <div> tag for building Cards. <div> is an invalid React Native Component. But shards-react allows passing other components to use instead of <div>. Try to pass tag prop to Card like this:
return (
<Card tag={View}>
{userDetails}
</Card>
);
If this won't help you, then this library cannot be used in react-native.

React navigation: React Invariant Violation: Element type is invalid: Check the render method of `NavigationContainer`

I just migrating react-navigation library into 3.0 as given in the example https://reactnavigation.org/docs/en/hello-react-navigation.html and I finally ended with the following error. Not sure what does this error mean?
Error
App.js
import React from "react";
import { View, Text } from "react-native";
import { createStackNavigator, createAppContainer } from "react-navigation";
import HomeScreen from './screens/Home';
const AppNavigator = createStackNavigator({
HomeScreen: {
screen: HomeScreen
}
});
const AppContainer = createAppContainer(AppNavigator);
export default class App extends React.Component {
render() {
return <AppContainer/>;
}
}
HomeScreen:
import React, { Component } from 'react';
import {
Text,
View
} from 'react-native';
export default class HomeScreen extends Component {
render() {
return (
<View style={{ flex: 1, alignItems: "center", justifyContent: "center" }}>
<Text>Home Screen</Text>
</View>
);
}
}
Edit 1:
If I render the Homescreen directly in App.js, I am just getting the home screen fine.
I mean call
export default HomeScreen;
instead of this
export default class App extends React.Component {
render() {
return <AppContainer/>;
}
}

React-Native the child component don't render the information within the parent component

I'm developing a React Native app that using a ScrollView. I want to display an amount of items (A card with title and a child component).
The problem comes when I have to render each item, while the parent renders ok, the child does not.
I don't know where could be the issue, here's my code:
import React, {Component} from 'react';
import {View, Text} from 'react-native';
const mismo =[
'Mismo',
'Mismo',
'Mismo',
'Mismo',
'Mismo'
];
class Mismo extends Component {
renderMismo2(){
mismo.map((item) =>{
return(
<View>
<Text>{item}</Text>
</View>
)
})
}
render(){
return(
<View>
{this.renderMismo2()}
</View>
);
}
}
export default Mismo;
=================================
import React, {Component} from 'react';
import {View, Text, ScrollView} from 'react-native';
import {Card} from 'react-native-elements';
import PriceCard from '../components/PriceCard';
import Mismo from '../components/Mismo';
class OrderPricingCard extends Component{
renderAllPrices(){
this.props.data.orders.map((item, i) => {
return(
<View>
<PriceCard
key={item.transporterName}
data={item}
/>
</View>
);
})
}
renderMismo(){
return(
<Mismo />
);
}
render () {
return (
<Card
containerStyle={styles.cardContainer}
title={`Pedido: ${this.props.data.id}`}
>
<ScrollView
horizontal
>
{this.renderMismo()}
{this.renderAllPrices()}
</ScrollView>
</Card>
);
}
}
const styles = {
cardContainer:{
borderRadius: 10,
shadowColor: "#000",
shadowOffset: {
width: 0,
height: 2,
},
shadowOpacity: 0.25,
shadowRadius: 3.84,
elevation: 5,
}
}
export default OrderPricingCard;
This can be an easy mistake to make! I've done it several times. What's happened is you've forgotten the return statement for the render methods (renderMismo2() and renderAllPrices()) found in each component. Although the map methods correctly have return statements, you're not actually returning anything from the functions themselves.
If you were to console.log() either of those function calls above the return in the React render() method, you would see undefined in the console.
Here's what they would look like corrected.
renderAllPrices(){
// added the 'return' keyword to begin the line below
return this.props.data.orders.map((item, i) => {
return(
<View>
<PriceCard
key={item.transporterName}
data={item}
/>
</View>
);
})
}
renderMismo2(){
// same here, added the 'return' keyword
return mismo.map((item) =>{
return(
<View>
<Text>{item}</Text>
</View>
)
})
}
I tested the above in a React Native sandbox and it works. Hope that helps!

Element type is invalid: expected a string [...] Check the render method of 'BurpSimV3'

i made a new app with the latest version of react native and it works. Then, i choose to downgrade and create a new app with version 0.44 for compatibility of certain components.. and this:
Error:
Here the code of my index
And here my ScenaPrincipale.js
import React, { Component } from 'react';
import {
StatusBar,
ImageBackground,
StyleSheet
} from 'react-native';
import Titolo from './titolo';
import Descrizione from './descrizione';
import BottonArea from './bottonarea';
import Banner from './banner';
export default class ScenaPrincipale extends Component {
render() {
return(
<ImageBackground source={require('../imgs/garfield.jpg')} style={styles.container}>
<StatusBar hidden/>
<Titolo/>
<Descrizione/>
<BottonArea/>
<Banner/>
</ImageBackground>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1
}
});
What can i do?
