How can Node.js and AWS-SDK be utilized to upload videos onto S3?

edit

To upload videos onto S3 using Node.js and AWS-SDK, the following steps can be followed:

1. Install the AWS-SDK package using npm.

2. Create an S3 bucket on AWS and ensure that it has the appropriate permissions to allow uploads.

3. Generate AWS access keys and ensure that they have the appropriate permissions to allow uploads to the S3 bucket.

4. Write a Node.js script to upload the video file to the S3 bucket. This involves creating an instance of the AWS.S3 class, specifying the bucket name, and setting the access keys.

5. Use the putObject method to upload the video file to the S3 bucket.

6. Set the appropriate Content-Type header based on the type of video file being uploaded.

Here is an example code snippet that demonstrates the above steps:

const AWS = require('aws-sdk');
const fs = require('fs');

// Create an instance of the S3 class
const s3 = new AWS.S3({
    accessKeyId: 'INSERT_ACCESS_KEY_HERE',
    secretAccessKey: 'INSERT_SECRET_KEY_HERE'
});

// Set the bucket name and video file path
const bucketName = 'INSERT_BUCKET_NAME_HERE';
const filePath = 'INSERT_VIDEO_FILE_PATH_HERE';

// Read the video file data
const videoData = fs.readFileSync(filePath);

// Set the Content-Type header based on the video file type
const contentType = 'video/mp4';

// Set the S3 parameters
const params = {
    Bucket: bucketName,
    Key: 'example.mp4',
    Body: videoData,
    ContentType: contentType
};

// Upload the video to S3
s3.putObject(params, function(err, data) {
    if (err) {
        console.log('Error uploading to S3:', err);
    } else {
        console.log('Upload success:', data);
    }
});

Note: This is a simple example and may need to be modified based on specific use cases.
