Reactjs Basic Tutorials


Friends now I proceed onwards and here is the working code snippet for Reactjs Multiple Images Upload with Preview and Delete and please use this carefully to avoid the mistakes:

1. Firstly friends we need fresh reactjs setup and for that we need to run below commands into our terminal and also w should have latest node version installed on our system:

npx create-react-app reactimageupload

cd reactimageupload

npm start // run the project

 

2. Now we need to run below commands to get bootstrap(for good layout), antd(for datepicker and form) modules into our react js app:

npm install antd

npm install bootstrap --save

npm start

 

3. Now friends, after are done with commands, now please open reactimageupload/src/App.js file and add below code inside it:

import React from 'react';

import './App.css';

//Bootstrap and jQuery libraries
import 'bootstrap/dist/css/bootstrap.min.css';


//Image upload modules
import { Upload, Modal } from 'antd';
import { PlusOutlined } from '@ant-design/icons';

import "antd/dist/antd.css";

class App extends React.Component {

  
  render(){

    //Uploaded url
    function getBase64(file) {
      return new Promise((resolve, reject) => {
        const reader = new FileReader();
        reader.readAsDataURL(file);
        reader.onload = () => resolve(reader.result);
        reader.onerror = error => reject(error);
      });
    }
    

    class PicturesWall extends React.Component {
      state = {
        previewVisible: false,
        previewImage: '',
        previewTitle: '',
        fileList: [
          {
            uid: '-1',
            name: 'image.png',
            status: 'done',
            url: 'https://zos.alipayobjects.com/rmsportal/jkjgkEfvpUPVyRjUImniVslZfWPnJuuZ.png',
          }
        ],
      };
    
      handleCancel = () => this.setState({ previewVisible: false });


      //Image Preview
      handlePreview = async file => {
        if (!file.url && !file.preview) {
          file.preview = await getBase64(file.originFileObj);
        }
    
        this.setState({
          previewImage: file.url || file.preview,
          previewVisible: true,
          previewTitle: file.name || file.url.substring(file.url.lastIndexOf('/') + 1),
        });
      };
    
      handleChange = ({ fileList }) => this.setState({ fileList });
    
      render() {
        const { previewVisible, previewImage, fileList, previewTitle } = this.state;
        const uploadButton = (
          <div>
            <PlusOutlined />
            <div style={{ marginTop: 8 }}>Upload</div>
          </div>
        );
        return (
          <>
            <Upload
              action="https://www.mocky.io/v2/5cc8019d300000980a055e76"
              listType="picture-card"
              fileList={fileList}
              onPreview={this.handlePreview}
              onChange={this.handleChange}
            >
              {fileList.length >= 8 ? null : uploadButton}
            </Upload>
            <Modal
              visible={previewVisible}
              title={previewTitle}
              footer={null}
              onCancel={this.handleCancel}
            >
              <img alt="example" style={{ width: '100%' }} src={previewImage} />
            </Modal>
          </>
        );
      }
    }


    return (
    <div className="MainDiv">
      <div className="jumbotron text-center">
          <h3>Therichpost.com</h3>
         
      </div>
      
      <div className="container">
          
          <PicturesWall />
        </div>
      </div>
  );
}
}

export default App;
