Here's a concise guide on how to use react-native-simple-login in JavaScript:

// Install react-native-simple-login
npm install react-native-simple-login

// Import react-native-simple-login
import React, { useState } from "react";
import {
    SafeAreaView,
    StyleSheet,
    TextInput,
    Button,
} from "react-native";
import Login from "react-native-simple-login";

// Create a login component
const App = () => {
    const [username, setUsername] = useState("");
    const [password, setPassword] = useState("");

    // Log in
    const onLogin = async () => {
        const { success, error } = await Login.login({
            username,
            password,
        });
        if (success) {
            // Login successful
        } else {
            // Login failed
        }
    };

    return (
        <SafeAreaView style={styles.container}>
            <TextInput
                style={styles.input}
                placeholder="Username"
                value={username}
                onChangeText={setUsername}
            />
            <TextInput
                style={styles.input}
                placeholder="Password"
                value={password}
                onChangeText={setPassword}
                secureTextEntry={true}
            />
            <Button
                title="Login"
                color="blue"
                onPress={onLogin}
            />
        </SafeAreaView>
    );
};

// Styles
const styles = StyleSheet.create({
    container: {
        flex: 1,
        justifyContent: "center",
        alignItems: "center",
    },
    input: {
        width: 200,
        height: 40,
        borderRadius: 5,
        padding: 10,
    },
});

// Render
export default App;
