it lloks kie this:

import firebase from 'firebase/app'
import firestore from 'firebase/firebase-firestore'


const firebaseConfig = {
  apiKey: "",
  authDomain: "",

  messagingSenderId: "",
  appId: "",
  measurementId: ""
};

firebase.initializeApp(firebaseConfig);

export const db = firebase.firstore()

note: firebase config can be found under the project setting in firebase

step 3.

create a form to collect data from user and update in firestore

<div class={classes.root}>
        <Typography variant='h3'>contact us</Typography>
        <br />
        <br />
        <br />
        <form noValidate=''>
          <Grid
            container
            direction='column'
            justify='center'
            alignItems='center'
          >
            <Grid container item>
              <TextField
                require={true}
                id='name'
                label='Name'
                variant='outlined'
                autoComplete='new-name'
                fullWidth
                value={name}
                onChange={(e) => setName(e.target.value)}
              />
            </Grid>
            <br />
            <br />
            <Grid container item>
              <TextField
                required
                id='email'
                label='Email'
                variant='outlined'
                autoComplete='new-email'
                fullWidth
                value={email}
                onChange={(e) => setEmail(e.target.value)}
              />
            </Grid>
            <br />
            <br />
            <Grid container item>
              <TextField
                required
                id='message'
                label='Message'
                fullWidth
                multiline
                rows={4}
                value={message}
                variant='outlined'
                onChange={(e) => setMessage(e.target.value)}
              />
            </Grid>
            <br />
            <br />
            <br />
            <br />
            <Grid container item>
              <Button
                variant='contained'
                fullWidth
                color='primary'
                onClick={onSubmitHandler}
              >
                Submit
              </Button>    
            </Grid>
          </Grid>
        </form>
        <Snackbar open={open} autoHideDuration={6000} onClose={handleClose}>
          <Alert onClose={handleClose} severity='success'>
            message submitted successfully!
          </Alert>
        </Snackbar>
      </div>

note: snackbar is for alert that the user data is submitted successfuly

now we write me make state for our form input so we can capture on change values from the input field and write firestore command to save data in

const classes = useStyle()
    const [name, setName] = useState('');
    const [email, setEmail] = useState('');
    const [message, setMessage] = useState('');
    const [open, setOpen] = useState(false)
    
    
 const onSubmitHandler = (e) =>{
        e.preventDefault()
        db.collection('contact').add({
            name: name,
            email:email,
            message :message,
        })
        .then(() => {
            setOpen(true);
        })
        .catch((error) =>{
            alert(error.message)
        })
      
       setName("")
       setEmail("")
       setMessage("")
       
    }

create a function for snackbar

   const handleClose = (e, reason) =>{
        if (reason === 'clickaway'){
           return(
               console.log("working")
           ) 
        }
        setOpen(false)
    }

    function Alert(props) {
      return <MuiAlert elevation={6} variant='filled' {...props} />;
    }

for styling the elements

we use makesStyles function from material to design our form

const useStyle = makeStyles((theme) => ({
    root:{
        width:"450px",
        marginTop:"150px",
        marginLeft:"600px"
        
    }
}))

note: we call usestyle () by using other variable(in this case i use classes = useStyles())

So hats it everyon. Hope you Enjoy!
