File MetaService with CRA and Firebase (very easy and works fine!)

Tell us what’s happening:
I decided to use Firebase for all 5 “Api and Microservice” - projects to get a “real world experience” instead of using Glitch + MongoDb.

Your code so far
I finished all 5 projects and let you have a look at the last one.

Working solution on Google Firebase (Hosting + Storage):
https://filemeta-4dcb1.firebaseapp.com/

There is one big issue with my solution:
I am quiet sure to not send a “formData” object. Hopefully you dont mind or correct it :)))

I used a “create-react-app” and coded everything as simple as possible:

App.js (will be attached to the Div(root) by index.js):

import React from 'react';
import Upload from './component/upload';

function App() {
  return (
    <div className="App">
        <h1>file metaservice</h1>
        <Upload />
    </div>
  );
}

export default App;

upload.js (this component includes everything except of the Firebase init):

import React, { Component } from "react";
import Firebase from "./firebase";

class Upload extends Component {
  constructor(props) {
    super(props);
    this.state = {
      file: "",
    };
    this.setFileState = this.setFileState.bind(this);
    this.fileUpload = this.fileUpload.bind(this);
  }
  setFileState = (e) => {
    this.setState({ [e.target.name]: e.target.files[0] });
  };
  fileUpload = (e) => {
    e.preventDefault();
    // if no file is selected
    if (!this.state.file) {
      console.log("please select a file");
    } else {
      // send file to the database
      const storageRef = Firebase.db.ref('fileupload/' + this.state.file.name);
      storageRef.put(this.state.file);
      storageRef.getMetadata().then(res => {
        document.getElementById('fileDiv').innerText = 'fileName: ' + res.name + ', fileSize: ' + res.size + "b" 
      })
    }
  };
  render() {
    return (
      <div id="fileDiv">
        <form>
          <label>
            <input type="file" name="file" onChange={this.setFileState} />
          </label>
          <br />
          <input type="submit" value="Submit" onClick={this.fileUpload} />
        </form>
      </div>
    );
  }
}

export default Upload;

and the firebase.js (to init Firebase):

import app from "firebase/app";
import "firebase/storage";

const firebaseConfig = {
    my firebaseConfig - data ...
  };

class Firebase {
  constructor() {
    app.initializeApp(firebaseConfig);
    this.db = app.storage();
  };
};

export default new Firebase();

package.json (dependencies):

{
  "dependencies": {
    "@testing-library/jest-dom": "^4.2.4",
    "@testing-library/react": "^9.5.0",
    "@testing-library/user-event": "^7.2.1",
    "react": "^16.13.1",
    "react-dom": "^16.13.1",
    "react-scripts": "3.4.1",
    "firebase": "*"
  }

Please let me know if you like it and if you think my solution should be accepted :))

Like it, subscribe it, share it, use it … whatever :)))

If you have any questions, feel free to ask!

Best regards
