PROBLEMS FACED

power problem
Data problem
Deployement problem

WHAT I LEARNT DURING THE PROCESSS

Patience

How firebase works with react

deploying CRA to vercel even with lots of warning

Creation process

the project is created with React.js using CRA ( Create react application )

now lets take a walk through the building process , now open your terminal , cd into the folder you wanna create the app in

npx create-react-app app_name

and this will create the new react app with everything

DEPENDENCIES

now for the project i used some list of dependencies , i used REACTSTRAP for the styling UI and Sass for my default styling this are some list og dependencies as follows

dep.png

LIST OF DEPENDENCIES
React router dom // used for routing
ReactStrap // used for the UI framework
ReactIcons // dependency used to add the Icons to the app
Firebase // i used it as for my database

setting everything up

now lets talk about the routing to use routing in react js just open your terminal in your root folder and type

npm install react-router-dom --save

this will install the router to your app

now by using import all the pages you wanna use and link the, to each other as shown in the image below rout.png

API USED

i used the DevTo.api to get some list of developers

ABOUT THE DATABASE USED !

i used Firebase storage ( firestore ) for the project , i used it collect list of uploaded items

STEPS

now go to Firebase official site
now create and account with firebase
then goto console and choose firebase storage

CREATING THE LEARNING BOT

this is how the bot is being created with js

 import React, {useState} from 'react';
import { Container , Form , Row , Col , Button  , Input} from 'reactstrap';
import './css/main.css';

import {MdArrowBack} from "react-icons/md";
import {RiSendPlane2Fill} from "react-icons/ri";
import {Link } from 'react-router-dom';
import {MdSettings} from 'react-icons/md'
import social from '../vectors/social.svg'

const Bot=()=>{

    //function for the bot 
    let [ask , setAsk]=useState('')
    let [hide ,setHide ]=useState('none')
    let [chaty,setChaty]=useState('')
    let [machine , setMachine]=useState('none')
    let [details , setDetails]=useState('block')
       let run=()=>{
            setAsk(localStorage.getItem('name'))

       }

       window.addEventListener('load',()=>run())
    const {  inbox ,btn,app,res }={
        dat:document.querySelector('.userMsg'),
        reply:document.querySelector('.reply'),
        inbox:document.querySelector('.inbox'),
        btn:document.querySelector('#btn'),
        app:document.querySelector('.msgs'),
        res:document.querySelector('.res'),
        clear:document.querySelector('#chat')
    }

        // the bot reply 
        const botReply=(asap)=>{
            let hello=document.createElement('p');
            let wr=document.createTextNode(asap)

             hello.appendChild(wr)
             app.appendChild(hello)
             hello.classList.add('red')


         }

         //human msg
         const  human=(chat)=>{
             let make=document.createElement('div')
             let write=document.createTextNode(chat);
             make.appendChild(write)
             //now append the msg to the div
             app.appendChild(make)

             make.classList.add('mess')

         }

    const user=()=> {

export default Bot;

you can see in the code above i used Regular expression to match for a good Gmail pattern ..

CREATING THE UPLOAD WITH FIREBASE

we will see how i used firebase to create the user upload

import React, { useState, useEffect } from 'react';
import {MdArrowBack} from "react-icons/md";
import {Link} from 'react-router-dom'
import { Container  , Card , Badge ,CardBody,BreadcrumbItem,Breadcrumb} from 'reactstrap'
import firebase from './firebase'
const Share=()=>{
    let [upload , setUpload]=useState('')
    let [msg , setMsg]=useState('')
    let [size_msg , setSize_msg]=useState('')
    let uploadTo=(e)=>{
        let file=e.target;
        let fileTo=file.files[0];
        let fileNames=fileTo.name;
            //let match for the pattern 
            let pattern=new RegExp(/\.pdf/)
                if(fileTo.name.match(pattern)){
                    //set the error msg back to normal
                    setMsg(false)

                    //now set the msg for the uploaaded files 
                    setUpload(fileTo.name)
                    let storageRef=firebase.storage().ref(`uploads/${fileNames}`)
                    let store=storageRef.put(fileTo)
                    console.log(store);
                    store.on('state_change',snapshot=>{
                        console.log('uploaed to firebase ');
                    })

                    //now upload to firebase 


                } else {
                   setMsg('only PDF files can be uploaded ')
                   setUpload(false)
                }

    }
    return (
        <>

            <Container>
            <header>

          <div className="errors">
                  <small className="err"> {msg}</small>
                  <small className="loadMsg">{upload}</small>
                </div>
          <div className="upload-btn" >
                <form action="" onSubmit={e=>e.preventDefault()}>
                   <label htmlFor="pdf">+</label>
                    <input type="file" name="load" id="pdf" style={{display:'none'}} onChange={uploadTo}/>


                </form>
                <br/>

             </div>
          </footer>
            </Container>

        </>
    )
}
export default Share ;

in the code snippet above , you can see i imported firebase i will show how to use firebasae with react.js

USING FIREBASE WITH REACT

first of all go to firebase , create an account with them
nos choose firebase storage
now create a firebase project then click on web
now create a new file and name it firebase.js
now collect your project id and secrete key as shown below
then export firebase as default
 import firebase from 'firebase'
import "firebase/firestore"
// For Firebase JS SDK v7.20.0 and later, measurementId is optional
const firebaseConfig = {
    apiKey: "your api key here",
    authDomain: "authDomain",
    projectId: "project domain",
    storageBucket: "storage bucket",
    messagingSenderId: "your message sender ID",
    appId: "appId",
    measurementId: "measurement"
  };
  firebase.initializeApp(firebaseConfig);
//now export firebase 
  export default firebase;

you can see in the above we imported firebase to our file now you can start importing firebase anywhere in your app also we used firebase to match the file upload type
