• how to change prettier format for react native

  my code formatting prettier didn't works well for react native, i don't understand where to config it but it works well with flutter

  from this code

        import { View, Text } from 'react-native'
      
      import React from 'react'
      
      export default function App() {
        return (
          <View>
      
      <Text>Apps</Text>   
  </View>
        )
      }
  

  it's formatted to this

  import {
    View,
    Text
  } from 'react-native'
  
  import React from 'react'
  
  export default function App() {
    return ( <
      View >
  
      <
      Text > Apps < /Text>
  
  
      <
      /View>
    )
  }

• Can you make complete apps using Flutter & Dart or just the UI part of an app?

  I'm confused about what Flutter framework actually does, I know that it uses Dart and have heard that both of them can be used to create cross-platform apps.

  But Wikipedia defines Flutter as a "UI Framework", so my question is, can you make a complete app (for mobile) which also has backend part (communicates with a database) built entirely using Flutter & Dart and not only the UI part?

  If you didn't get my question, here is an example:

  Suppose a front-end web developer works on client side programming in his job, and the backend logic is written by another backend developer.

  When it comes to mobile app development, suppose as a Flutter developer, your job is to create apps, but does that mean that as a Flutter developer, you'll only write the front-end logic and leave the backend part for another backend developer like in web world? Can Flutter developers also write the backend of an app using only Flutter & Dart? If not, then who writes the backend of a mobile app and what tools/languages/frameworks does he uses?
• HTTP authentication with PHP for specific pages

  I have been trying to fix one issue for the last two weeks but didn't find any solution to my problem. So, I am trying to add HTTP authentication with PHP 7.4.

  The main issue

  I have to add restrictions for specific URLs ( For example, https://example.com/photos ) with PHP, and I am using the below code. But the problem is I have to show logged-in users on other pages, too. For example, if I didn't log in, then anything to show, but if I am logged in need to show username and password on all pages, but again I have to restrict only specific pages.

  PHP Code:

  Header("WWW-Authenticate: Basic realm='Members Only' valid-user");
  http_response_code(401);
  echo "<script> window.location.replace( 'https://example.com/sign-up' ) </script>";
  exit;
  

  .htaccess Code:

  AuthUserfile PATH_TO_THE_FILE/.htpasswd
  AuthName "Members Only"
  AuthType Basic
  AuthBasicProvider file
  

  I hope someone will help me soon.
• Firebase Authentication with custom domain

• Acces to XMLHttpRequest at 'https://api-link/login' from origin 'http://localhost/3000' has been blocked by cors policy. (React, , firebase, JWT))

  When I try to implement a secure login system in React application with firebase using JSON Web Token (JWT) I am getting this error: Acces to XMLHttpRequest at 'https://api-link/login' from origin 'http://localhost/3000' has been blocked by cors policy. I am using node js for the backend.

  I also use cors middleware:

  const cors = require("cors");
  app.use(cors());
  

  My Backend Code:

    const verifyJWT = (req, res, next) => {
    const authHeader = req.headers.authorization;
    console.log(authHeader);
  
    if (!authHeader) {
      return res.status(401).send({
        message: "unauthorized access",
      });
    }
    const token = authHeader.split(" ")[1];
    jwt.verify(token, process.env.ACCESS_TOKEN_SECRET, (err, decoded) => {
      if (err) {
        return res.status(403).send({ message: "forbidden access" });
      } else {
        console.log("decoded", decoded);
        req.decoded = decoded;
        next();
      }
    });
  };
  

  Backend login route

    app.post("/login", async (req, res) => {
    const user = req.body;
    const accessToken = jwt.sign(user, process.env.ACCESS_TOKEN_SECRET, {
      expiresIn: "1d",
    });
    res.send({ accessToken });
  });
  

  My Client-side code:

  const handleSubmit = async (e) => {    
  e.preventDefault();
  await signInWithEmailAndPassword(values.email, values.password);
  const email = values.email;
  
  const { data } = await axios.post(
    "https://stark-sands-89628.herokuapp.com/login",
    { email }
  );
  localStorage.setItem("accessToken", data.accessToken)};
