Web developers who want to build an application using ReactJS or write codes for building a website must consider the react file upload to ensure that users can upload any file they need. Uploading file in ReactJS is vital for the developer while creating his application. The truth is that there are several ways with which you can create a ReactJS upload file, but if you want to make a ReactJS file upload that is strong and won’t be archaic, then this article will show you some of the tricks you need to include in the creation of reacting upload file. Before moving into the guide for future-proofing your React , you must remember some basics about ReactJS. file upload What Is ReactJS ReactJS is JavaScript library developers use in web programming to create interactive website components. Developers use ReactJS to build user interfaces on websites, and they have access to tools such as; The choice to use JavaScript to exploit their DOM A virtual DOM to augment their website's effectiveness Snippets and components of React Code. What Are The Components Of ReactJS Any developer who uses ReactJS to build applications or websites will come across components in ReactJS because it is one of the fundamental build-ups. React JS comprises two components, and they are; Functional Components Developers create Functional Components through JavaScript Functions, and the code for it is as follows; const Democomponent = () => {
  return <h1>Welcome Message!</h1>;
}; Class Components They are not as simple as the functional components and are complicated. While the available components operate without any components, Class components work with every other component. The code for it is as follows; class Democomponent extends React.Component {
  render() {
    return <h1>Welcome Message!</h1>;
  }
} How To Future-Proof Your React File Uploader It is very reasonable for you to ensure that your React file upload stays in shape and does not become old. If you have been wondering how to go about this, then the following pieces of information will settle your curiosity here. Adding a new element such as React-Uploady will upgrade the features of your upload file react. React-Uploady is a light library that allows developers to create a user interface and file uploader features with little lines of code. React-Uploady is a library that contains modernized components of upload file react applications. It includes every element involved in file uploads, such as the buttons, progress, and upgrades. Before using this library, make sure you have Node.js and Node Package Manager installed on your device. What Are The Steps To Follow When Using React-Uploady Below are the following steps to follow when adding using React-Upload: Step 1: Install the React application, create-react-app npm install -g create-react-app Create a new project using the create-react-app and include the project’s name, whichever you prefer; in this case, we will use filestack. create-react-app filestack Go to your project guide and begin your developing server by writing the following code; cd filestack && npm start After you must have done the above processes, install the following packages for React-Uploady, but before you do that, here are some things to note about them; @rpldy/upload-button; Upload button component @rpldy/uploady; main component rc-progress ; File Upload progress component Install the following packages into the react app by writing the following code; npm i @rpldy/upload-button

@rpldy/uploady rc-progress Step 2: Then create a Header component for the app by opening a new file, Header.JS, inside your src file. After that, build a functional component by writing the following codes; import React from "react";
export default function App() {
  return (
    <div>
      <h1>File upload with Filestack</h1>
    </div>
  );
} You successfully created a functional component with an h1 tag with the inscription ‘File upload with Filestack.’ Then, render your Header feature inside the App feature by writing the following codes; import React from "react";

export default function App() {
  return (
    <div className="App">
      <Header />
    </div>
  );
} Step 3: The next step is to create your file upload feature using the App.js component. You need to import the packages you installed, use the upload-button package to render your upload button, and add the Upload component to your app to carry this out. Do this by writing the following codes; import React, { useState } from "react";

import Header from "./Header";

import "./App.css";

import { Line } from "rc-progress";

import Uploady, { useItemProgressListener } from "@rpldy/uploady";

import UploadButton from "@rpldy/upload-button";

import { createMockSender } from "@rpldy/sender"; After doing this, write the following codes to create a state for your file upload progress before making it a feature in your app; const UploadProgress = () => {
  const [progress, setProgess] = useState(0);

  const progressData = useItemProgressListener();

  if (progressData && progressData.completed > progress) {
    setProgess(() => progressData.completed);
  }
}; Step 4: Then add the line and style it to complete the file upload progress feature with the following codes; return (
  progressData && (
    <Line
      style={{
        height: "10px",

        marginTop: "20px",
      }}
      strokeWidth={2}
      strokeColor={progress === 100 ? "#00a626" : "#2db7f5"}
      percent={progress}
    />
  )
); After that, render the whole components on the app with the following codes; export default function App() {
  return (
    <Uploady destination={{ url: "http://server.com" }} enhancer={mockEnhancer}>
      <div className="App">
        <Header />

        <UploadButton />

        <UploadProgress />
      </div>
    </Uploady>
  );
} Add enhancer to make the React file upload feature more upgraded: Enhancer = (uploader) => {
  const mockSender = createMockSender({
    delay: 1500,
  });

  uploader.update({ send: mockSender.send });

  return uploader;
}; Step 5: To complete the process, add the styles with the following codes: App {
     font-family: arial, sans-serif;
     text-align: center;
     margin-top: 20px;
}
 body {
     background: #5c6e91;
     color: #eeeded;
}
 button {
     height: 60px;
     width: 200px;
     font-size: 22px;
     background-color: #8f384d;
     color: #eeeded;
     text-transform: uppercase;
     cursor: pointer;
} The codes will result in your React file upload feature being ready for an upgrade. How Can You Utilize FormData To Create Multiple Files Upload For React Upload File Feature Another way to strengthen your React file upload feature is by ensuring that the user can upload multiple files. It is possible with a new object called FormData. Write the following codes through the use of formData.Append function uploadFile(files, user) {
  var formData = new FormData();

  files.map((file, index) => {
    formData.append(`file${index}`, file);
  });

  formData.append("user", user);

  fetch("https://path/to/api", {
    // content-type header should not be specified!

    method: "POST",

    body: formData,
  })
    .then((response) => response.json())

    .then((success) => {
      // Do something with the successful response
    })

    .catch((error) => console.log(error));
