Upload the image from your file and display it on your page in react, you can also get the image object in the state when we select the image to display on the webpage you have to convert the image object to object using URL.createObjectURL(fileObject)

import React, { Component } from "react";
class DisplayImage extends Component { constructor(props) { super(props); this.state = { image: null }; // if we are using arrow function binding in not required // this.onImageChange = this.onImageChange.bind(this); } onImageChange = event => { if (event.target.files && event.target.files[0]) { let img = event.target.files[0]; this.setState({ image: URL.createObjectURL(img) }); } }; render() { return ( <div> <div> <div> <img src={this.state.image} /> <h1>Select Image</h1> <input type="file" name="myImage" onChange={this.onImageChange} /> </div> </div> </div> ); }
}
export default DisplayImage;

If you want to upload image and post it to an API. Then you install react-image-uploader. It saves the image to your local port and also in your database by raising a POST request.

using react-uploady you can do this very easily:

import React from "react";
import Uploady from "@rpldy/uploady";
import UploadButton from "@rpldy/upload-button";
import UploadPreview from "@rpldy/upload-preview";
const filterBySize = (file) => { //filter out images larger than 5MB return file.size <= 5242880;
};
const App = () => ( <Uploady destination={{ url: "" }} fileFilter={filterBySize} accept="image/*" > <UploadButton /> <UploadPreview /> </Uploady>
);
