How to upload images on my React app from firebase storage?

I am trying to make a social media app. I wanted to add a feature of uploading pictures but I don't know how to fetch those pictures in my firebase storage and display all of them as a post on my app.

This is my firebase.js file

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

const firebaseConfig = {
    apiKey: "AIzaSyCbiHH-zpob5AytooHMxrB_oncIz5wAcgg",
    authDomain: "expresate-react.firebaseapp.com",
    databaseURL: "https://expresate-react-default-rtdb.firebaseio.com",
    projectId: "expresate-react",
    storageBucket: "expresate-react.appspot.com",
    messagingSenderId: "400618187775",
    appId: "1:400618187775:web:d78270044e4b1d464215ca"
  };
firebase.initializeApp(firebaseConfig);

const storage = firebase.storage();

export { storage, firebase as default };

This is the function which uploads the image on the firebase storage.

const image = this.state.selectedFile;

    const uploadTask = storage.ref(`images/${image.name}`).put(image);
    uploadTask.on(
        "state_changed",
        snapshot => {},
        error => {
            console.log(error);
        },
        () => {
            storage
            .ref("images")
            .child(image.name)
            .getDownloadURL()
            .then(url => {
              this.setState({url: url, selectedFile: null});
            });
        }
    );

The upload feature is working perfectly I can see the files in firebase storage. Now, how do I fetch them and display them on my app?

Thank you

You already get the url with getDownloadURL. It is an url like this one.

You can use that to display your image. Just put that url into a img like here:


<img src={url} />
