Uploading Files to Google Cloud Storage using ReactJS

Introduction

In this article, we will explore how to upload files to Google Cloud Storage using ReactJS. Google Cloud Storage is a cloud-based object storage service that allows users to store and manage large amounts of data. With ReactJS, we can create a web application that allows users to upload files to Google Cloud Storage.

Prerequisites

Before we begin, make sure you have the following prerequisites:

  • A Google Cloud account

  • A Google Cloud Storage account

  • A ReactJS project set up

  • Node.js installed on your machine

Step 1: Set up Google Cloud Storage

To upload files to Google Cloud Storage, you need to set up a Google Cloud Storage account. Here’s how:

  • Go to the Google Cloud Console and create a new project.

  • Click on "Select a project" and then click on "New Project".

  • Enter a project name and click on "Create".

Step 2: Set up Google Cloud Storage credentials

To upload files to Google Cloud Storage, you need to set up credentials for your project. Here’s how:

  • Go to the Google Cloud Console and navigate to "IAM & Admin" > "Service accounts".

  • Click on "Create service account" and then click on "Create key".

  • Choose "JSON key file" and then click on "Create".

  • Download the JSON key file and save it to a secure location.

Step 3: Install required packages

To upload files to Google Cloud Storage using ReactJS, you need to install the following packages:

  • google-cloud-storage: This package provides a client library for Google Cloud Storage.

  • axios: This package provides a promise-based HTTP client for making HTTP requests.

You can install these packages using npm or yarn:

npm install google-cloud-storage axios

or

yarn add google-cloud-storage axios

Step 4: Create a ReactJS component to upload files

Here’s an example of a ReactJS component that uploads files to Google Cloud Storage:

import React, { useState } from 'react';

import axios from 'axios';



const UploadFilesToGoogleCloudStorage = () => {

  const [file, setFile] = useState(null);

  const [uploading, setUploading] = useState(false);

  const [error, setError] = useState(null);



  const handleFileChange = (event) => {

    setFile(event.target.files[0]);

  };



  const handleUpload = () => {

    setUploading(true);

    const formData = new FormData();

    formData.append('file', file);



    axios.post('https://storage.googleapis.com/cloud-storage/upload', formData)

      .then((response) => {

        if (response.status === 201) {

          console.log('File uploaded successfully');

        } else {

          setError(response.data.error);

        }

      })

      .catch((error) => {

        setError(error.message);

      })

      .finally(() => {

        setUploading(false);

      });

  };



  return (

    <div>

      <h1>Upload Files to Google Cloud Storage</h1>

      <input type="file" onChange={handleFileChange} />

      <button onClick={handleUpload}>Upload</button>

      {uploading ? (

        <p>Uploading...</p>

      ) : error ? (

        <p>Error: {error}</p>

      ) : (

        <p>File uploaded successfully!</p>

      )}

    </div>

  );

};



export default UploadFilesToGoogleCloudStorage;

Step 5: Create a ReactJS component to display uploaded files

Here’s an example of a ReactJS component that displays uploaded files:

import React from 'react';

import axios from 'axios';



const DisplayUploadedFiles = () => {

  const [files, setFiles] = useState([]);



  const handleFileChange = (event) => {

    setFiles(event.target.files);

  };



  const handleDownload = (file) => {

    const formData = new FormData();

    formData.append('file', file);



    axios.post('https://storage.googleapis.com/cloud-storage/download', formData)

      .then((response) => {

        const blob = new Blob(response.data, { type: response.headers['content-type'] });

        const url = URL.createObjectURL(blob);

        const a = document.createElement('a');

        a.href = url;

        a.download = file.name;

        a.click();

      })

      .catch((error) => {

        console.error(error);

      });

  };



  return (

    <div>

      <h1>Uploaded Files</h1>

      <ul>

        {files.map((file) => (

          <li key={file.name}>

            <a href={URL.createObjectURL(file)} download={file.name}>

              {file.name}

            </a>

          </li>

        ))}

      </ul>

    </div>

  );

};



export default DisplayUploadedFiles;

Step 6: Create a ReactJS component to display uploaded files in Google Cloud Storage

Here’s an example of a ReactJS component that displays uploaded files in Google Cloud Storage:

import React from 'react';

import axios from 'axios';

import { GoogleCloudStorage } from 'google-cloud-storage';



const GoogleCloudStorageComponent = () => {

  const [files, setFiles] = useState([]);



  const handleFileChange = (event) => {

    setFiles(event.target.files);

  };



  const handleDownload = (file) => {

    const formData = new FormData();

    formData.append('file', file);



    axios.post('https://storage.googleapis.com/cloud-storage/download', formData)

      .then((response) => {

        const blob = new Blob(response.data, { type: response.headers['content-type'] });

        const url = URL.createObjectURL(blob);

        const a = document.createElement('a');

        a.href = url;

        a.download = file.name;

        a.click();

      })

      .catch((error) => {

        console.error(error);

      });

  };



  const uploadFilesToGoogleCloudStorage = () => {

    const storage = new GoogleCloudStorage({

      projectId: 'your-project-id',

      credentials: {

        type: 'service_account',

        client_email: 'your-client-email',

        private_key_id: 'your-private-key-id',

        private_key: 'your-private-key',

        client_id: 'your-client-id',

      },

    });



    const files = files.map((file) => {

      return {

        name: file.name,

        url: file.url,

        type: file.type,

      };

    });



    const upload = storage.bucket('your-bucket-name').upload(files);



    console.log(upload);

  };



  return (

    <div>

      <h1>Upload Files to Google Cloud Storage</h1>

      <button onClick={uploadFilesToGoogleCloudStorage}>Upload Files</button>

      <ul>

        {files.map((file) => (

          <li key={file.name}>

            <a href={file.url} download={file.name}>

              {file.name}

            </a>

          </li>

        ))}

      </ul>

    </div>

  );

};



export default GoogleCloudStorageComponent;
