Using Amplify + Storage for Video Uploads in Web Apps

, document.getElementById('root')); serviceWorker.unregister(); Configuring S3 for Video Uploads Step 3: Set Up Storage with AWS Amplify Next, configure Amplify to enable storage for your video files. You will do this by using the @aws-amplify/storage module. First, use the following command to add storage to your Amplify app: amplify add storage Follow the CLI prompts to configure the S3 bucket for video uploads. Once configured, push the changes to AWS: amplify push This sets up an S3 bucket and links it to your Amplify app, allowing you to store video files securely. Implementing Video Uploads in React With AWS Amplify and S3 set up, you can now integrate the file upload functionality into your web app. The Storage module of AWS Amplify is used to handle the uploading of files to S3. Step 4: Implement Video Upload Component In your React app, create a simple form that allows users to select a video file for upload. import React, { useState } from 'react'; import { Storage } from 'aws-amplify'; function VideoUpload() { const [file, setFile] = useState(null); const [uploadProgress, setUploadProgress] = useState(0); const handleFileChange = (event) => { setFile(event.target.files[0]); }; const handleUpload = async () => { if (!file) { alert('Please choose a video to upload.'); return; } try { const fileName = `videos/${Date.now()}_${file.name}`; const uploadResult = await Storage.put(fileName, file, { contentType: file.type, progressCallback: (progress) => { setUploadProgress(Math.round((progress.loaded / progress.total) * 100)); } }); alert('Video uploaded successfully!'); console.log('Upload result:', uploadResult); } catch (error) { console.error('Error uploading video:', error); alert('Error uploading video'); } }; return (

{uploadProgress > 0 &&

Progress: {uploadProgress}%

}

); } export default VideoUpload; Explanation : File Input : The input tag allows the user to select a video file. The file is saved in the file state when selected. Handle Upload : The handleUpload function uploads the selected video to S3 using Storage.put() from AWS Amplify. This function takes the file, uploads it to S3, and tracks the upload progress. Progress Bar : While the video uploads, the progress is tracked and displayed on the screen. Handling Video Playback Once the video is uploaded, you can display it to users. Use the URL generated by S3 to show the uploaded video within your app. Step 5: Display Video After Upload To display the video, retrieve the file URL from S3 and embed it in the video element: import React, { useState } from 'react'; import { Storage } from 'aws-amplify'; function VideoDisplay({ videoKey }) { const [videoUrl, setVideoUrl] = useState(''); const getVideoUrl = async () => { try { const url = await Storage.get(videoKey); setVideoUrl(url); } catch (error) { console.error('Error retrieving video:', error); } }; return (

{videoUrl &&

); } export default VideoDisplay; Explanation: getVideoUrl() : Uses the Storage.get() method to retrieve the video URL from S3. Video Element : The video is displayed using the URL provided by S3. The controls attribute adds basic video playback controls. Best Practices for Video Uploads and Playback Security : Ensure that the video files uploaded to S3 are secure. Use AWS IAM policies to restrict access to only authorized users. File Size : Large video files can take time to upload. Consider adding file size restrictions and using a multipart upload for larger videos. Progress Tracking : For a better user experience, provide real-time progress indicators and handle interruptions in case of upload failures. Metadata : Store additional video metadata, such as file size, duration, and format, to enhance the user experience and improve content management.
