In this tutorial, we will learn how to build a social media app using React Native and Firebase. We will be using Firebase for authentication, database, and storage functionality. React Native will allow us to develop our app for both iOS and Android platforms using a single codebase.<\/p>\n
In order to follow along with this tutorial, you will need the following:<\/p>\n
Let’s start by setting up a new React Native project. Open your terminal and run the following commands:<\/p>\n
npx react-native init SocialMediaApp\ncd SocialMediaApp\n<\/code><\/pre>\nThis will create a new React Native project called “SocialMediaApp” and navigate you into the project directory.<\/p>\n
Installing Firebase Dependencies<\/h2>\n
Next, we need to install the necessary Firebase dependencies for our project. Run the following command in your terminal:<\/p>\n
npm install @react-native-firebase\/app @react-native-firebase\/auth @react-native-firebase\/database @react-native-firebase\/storage\n<\/code><\/pre>\nInitializing Firebase<\/h2>\n
To use Firebase in our app, we need to initialize it. Create a new file called firebase.js<\/code> in the project’s root directory and add the following code:<\/p>\nimport * as firebase from 'firebase';\nimport '@firebase\/auth';\nimport '@firebase\/database';\nimport '@firebase\/storage';\n\nconst firebaseConfig = {\n \/\/ YOUR FIREBASE CONFIG HERE\n};\n\nif (!firebase.apps.length) {\n firebase.initializeApp(firebaseConfig);\n}\n\nexport { firebase };\n<\/code><\/pre>\nReplace YOUR FIREBASE CONFIG HERE<\/code> with your Firebase project’s configuration. You can find this configuration in the Firebase console of your project.<\/p>\nSetting up Navigation<\/h2>\n
For our app’s navigation, we will be using React Navigation. Run the following command in your terminal to install the necessary dependencies:<\/p>\n
npm install @react-navigation\/native @react-navigation\/stack\n<\/code><\/pre>\nNext, create a new file called AppNavigator.js<\/code> in the project’s root directory and add the following code:<\/p>\nimport * as React from 'react';\nimport { NavigationContainer } from '@react-navigation\/native';\nimport { createStackNavigator } from '@react-navigation\/stack';\n\nimport HomeScreen from '.\/screens\/HomeScreen';\nimport LoginScreen from '.\/screens\/LoginScreen';\nimport SignupScreen from '.\/screens\/SignupScreen';\n\nconst Stack = createStackNavigator();\n\nfunction AppNavigator() {\n return (\n <NavigationContainer>\n <Stack.Navigator>\n <Stack.Screen\n name=\"Home\"\n component={HomeScreen}\n options={{ title: 'Home' }}\n \/>\n <Stack.Screen\n name=\"Login\"\n component={LoginScreen}\n options={{ title: 'Login' }}\n \/>\n <Stack.Screen\n name=\"Signup\"\n component={SignupScreen}\n options={{ title: 'Signup' }}\n \/>\n <\/Stack.Navigator>\n <\/NavigationContainer>\n );\n}\n\nexport default AppNavigator;\n<\/code><\/pre>\nCreating Screens<\/h2>\n
Let’s create the screens for our app. Create a new directory called screens<\/code> in the project’s root directory and navigate into it.<\/p>\nInside the screens<\/code> directory, create the following files and add the respective code:<\/p>\n\nHomeScreen.js<\/code><\/li>\n<\/ul>\nimport React from 'react';\nimport { View, Text } from 'react-native';\n\nfunction HomeScreen() {\n return (\n <View>\n <Text>Home Screen<\/Text>\n <\/View>\n );\n}\n\nexport default HomeScreen;\n<\/code><\/pre>\n\nLoginScreen.js<\/code><\/li>\n<\/ul>\nimport React from 'react';\nimport { View, Text } from 'react-native';\n\nfunction LoginScreen() {\n return (\n <View>\n <Text>Login Screen<\/Text>\n <\/View>\n );\n}\n\nexport default LoginScreen;\n<\/code><\/pre>\n\nSignupScreen.js<\/code><\/li>\n<\/ul>\nimport React from 'react';\nimport { View, Text } from 'react-native';\n\nfunction SignupScreen() {\n return (\n <View>\n <Text>Signup Screen<\/Text>\n <\/View>\n );\n}\n\nexport default SignupScreen;\n<\/code><\/pre>\nImporting Screens<\/h2>\n
Let’s import the screens in AppNavigator.js<\/code> to make them functional. Update the import statements at the top of the file as follows:<\/p>\nimport HomeScreen from '.\/screens\/HomeScreen';\nimport LoginScreen from '.\/screens\/LoginScreen';\nimport SignupScreen from '.\/screens\/SignupScreen';\n<\/code><\/pre>\nAdding Firebase Authentication<\/h2>\n
To enable authentication in our app, we will use the Firebase Auth module. Open SignupScreen.js<\/code> and update the code as follows:<\/p>\nimport React, { useState } from 'react';\nimport { View, TextInput, Button } from 'react-native';\n\nimport { firebase } from '..\/firebase\/firebase';\n\nfunction SignupScreen({ navigation }) {\n const [email, setEmail] = useState('');\n const [password, setPassword] = useState('');\n\n const handleSignUp = () => {\n firebase\n .auth()\n .createUserWithEmailAndPassword(email, password)\n .then(() => {\n console.log('User successfully registered!');\n navigation.navigate('Home');\n })\n .catch((error) => {\n console.error(error);\n });\n };\n\n return (\n <View>\n <TextInput\n placeholder=\"Email\"\n value={email}\n onChangeText={(text) => setEmail(text)}\n \/>\n <TextInput\n placeholder=\"Password\"\n secureTextEntry\n value={password}\n onChangeText={(text) => setPassword(text)}\n \/>\n <Button title=\"Sign Up\" onPress={handleSignUp} \/>\n <\/View>\n );\n}\n\nexport default SignupScreen;\n<\/code><\/pre>\nSimilarly, update the code in LoginScreen.js<\/code> as follows:<\/p>\nimport React, { useState } from 'react';\nimport { View, TextInput, Button } from 'react-native';\n\nimport { firebase } from '..\/firebase\/firebase';\n\nfunction LoginScreen({ navigation }) {\n const [email, setEmail] = useState('');\n const [password, setPassword] = useState('');\n\n const handleLogin = () => {\n firebase\n .auth()\n .signInWithEmailAndPassword(email, password)\n .then(() => {\n console.log('User successfully logged in!');\n navigation.navigate('Home');\n })\n .catch((error) => {\n console.error(error);\n });\n };\n\n return (\n <View>\n <TextInput\n placeholder=\"Email\"\n value={email}\n onChangeText={(text) => setEmail(text)}\n \/>\n <TextInput\n placeholder=\"Password\"\n secureTextEntry\n value={password}\n onChangeText={(text) => setPassword(text)}\n \/>\n <Button title=\"Login\" onPress={handleLogin} \/>\n <\/View>\n );\n}\n\nexport default LoginScreen;\n<\/code><\/pre>\nAdding Firebase Database<\/h2>\n
To store and retrieve data, we will use the Firebase Database module. Update the code in HomeScreen.js<\/code> to add data to the database:<\/p>\nimport React, { useState } from 'react';\nimport { View, TextInput, Button } from 'react-native';\n\nimport { firebase } from '..\/firebase\/firebase';\n\nfunction HomeScreen() {\n const [text, setText] = useState('');\n\n const handleAddData = () => {\n const dbRef = firebase.database().ref();\n const data = {\n textValue: text,\n };\n dbRef.push(data).then(() => {\n console.log('Data added successfully!');\n });\n };\n\n return (\n <View>\n <TextInput\n placeholder=\"Enter some text\"\n value={text}\n onChangeText={(text) => setText(text)}\n \/>\n <Button title=\"Add Data\" onPress={handleAddData} \/>\n <\/View>\n );\n}\n\nexport default HomeScreen;\n<\/code><\/pre>\nTo retrieve data from the database, update the code in HomeScreen.js<\/code> as follows:<\/p>\nimport React, { useState, useEffect } from 'react';\nimport { View, TextInput, Button, FlatList, Text } from 'react-native';\n\nimport { firebase } from '..\/firebase\/firebase';\n\nfunction HomeScreen() {\n const [text, setText] = useState('');\n const [data, setData] = useState([]);\n\n useEffect(() => {\n const dbRef = firebase.database().ref();\n dbRef.on('value', (snapshot) => {\n const firebaseData = snapshot.val();\n const dataArray = [];\n for (let id in firebaseData) {\n dataArray.push({ id, ...firebaseData[id] });\n }\n setData(dataArray);\n });\n }, []);\n\n const handleAddData = () => {\n const dbRef = firebase.database().ref();\n const newData = {\n textValue: text,\n };\n dbRef.push(newData).then(() => {\n setText('');\n });\n };\n\n return (\n <View>\n <TextInput\n placeholder=\"Enter some text\"\n value={text}\n onChangeText={(text) => setText(text)}\n \/>\n <Button title=\"Add Data\" onPress={handleAddData} \/>\n <FlatList\n data={data}\n renderItem={({ item }) => <Text>{item.textValue}<\/Text>}\n keyExtractor={(item) => item.id}\n \/>\n <\/View>\n );\n}\n\nexport default HomeScreen;\n<\/code><\/pre>\nAdding Firebase Storage<\/h2>\n
To upload and retrieve images, we will use the Firebase Storage module. Update the code in HomeScreen.js<\/code> to add image upload functionality:<\/p>\nimport React, { useState } from 'react';\nimport { View, TextInput, Button, Image } from 'react-native';\n\nimport { firebase } from '..\/firebase\/firebase';\n\nfunction HomeScreen() {\n const [image, setImage] = useState(null);\n\n const handleChooseImage = () => {\n \/\/ Image picker code here\n };\n\n const handleUploadImage = () => {\n const storageRef = firebase.storage().ref();\n const imageRef = storageRef.child(image.fileName);\n imageRef.putFile(image.uri).then(() => {\n console.log('Image uploaded successfully!');\n });\n };\n\n return (\n <View>\n <Button title=\"Choose Image\" onPress={handleChooseImage} \/>\n {image && <Image source={{ uri: image.uri }} \/>}\n <Button title=\"Upload Image\" onPress={handleUploadImage} \/>\n <\/View>\n );\n}\n\nexport default HomeScreen;\n<\/code><\/pre>\nConclusion<\/h2>\n
