• 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>
    )
  }

• Discord.js How to find all the servers a different discord user is in

  I want to make a website where people can change what the bot does on their server. I'm currently using Autocode to make it (using discord.js). I also don't know how to link OAouth2 with the code. This is the full code of what I'm at

  // Using Node.js 14.x +
  // use "lib" package from npm
  const lib = require('lib')({
    token: 'token_here'
  });
  // make API request
  let result = await lib.discord.guilds['@0.2.4'].list({
    limit: 100
  });
  console.log(result[0]);
  

  it works but only gets what guilds the bot is in. I tried to link it to the user but I couldn't find out what to put
• How to control a sainsmart relay using NodeJs

  Hi I am trying to turn on and off a relay to power 12v lights and others, using sainsmart relays.

  I would like to my own interface with buttons so I would setup a web page with express to interact with my nodejs server and this would control the gpio and relays

  Since I am new to raspberry pi I don't really know how to do it and all the exemples that I can find are using switches or just 27 sec videos that do not show any code

  const Gpio = require('pigpio').Gpio;
  
  const frontLight = new Gpio(12, {
      mode: Gpio.OUTPUT,
      pullUpDown: Gpio.PUD_DOWN,
      edge: Gpio.FALLING_EDGE
  }
  
  console.log('GPIO Outputs Configured');
  
  //this above is from the basic switch video that I kinda adapted by instinct
  //and under is something I put up to show what I would like to be
  
  frontLight.on('interrupt', function(level) {
      //checkbox1 would be on the express web page
      if(checkbox1.Checked()){
          frontLight.Relay.On
          console.log('On');
      }
      else {
          frontLight.Relay.Off
          console.log('Off');
      }
  });
  

  my configuration is :

• Raspberry PI 4 camera snapshot not working

  I am working on a project with raspberry pi 4 and a camera. I wanted to try and check if the camera was up and running but I am running into an issue when attempting to take a snapshot. I have set up the camera correctly as the camera is detected by the raspberry pi. Below are some of the commands I run:

  pi@raspberrypi:~ $ vcgencmd get_camera
  
  supported=1 detected=1

  mmal: camera component couldn't be enabled
  
  mmal: main: Failed to create camera component
  
  mmal: Failed to run camera app. Please check for firmware updates
  

  The above is the error I am getting, I assume the problem is that the camera is being used by another processes, but I do not know how to find those process.

  Any input on this will be highly appreciated.
• Cannot unpack noniterable bool object

  I'm new to Python and posting on SO.

  I'm doing a class project on trying to create an automated climate control system with a Raspberry pi(Pi4 4GB) and a DHT. Here is my current error and code and I'm not sure what's causing the fail in the loop. It works for a while then errors out. It seems to error when it gets a bad read from the sensor, but until then it works fine.
