Accessing metadata from a Spaces file

Hi there,

You can access a file’s metadata in DigitalOcean Spaces by using the AWS SDK for S3, as Spaces is S3-compatible. Here’s an example in JavaScript using the AWS SDK for Node.js:

var AWS = require('aws-sdk');

// Set the region 
AWS.config.update({region: 'nyc3'});  // update to your region

// Create S3 service object with DigitalOcean Spaces endpoint
var s3 = new AWS.S3({
    endpoint: 'nyc3.digitaloceanspaces.com',  // update to your Spaces endpoint
    accessKeyId: 'YOUR_ACCESS_KEY',   // replace with your access key
    secretAccessKey: 'YOUR_SECRET_KEY'  // replace with your secret key
});

var params = {
    Bucket: 'your-bucket-name', 
    Key: 'your-object-key'
};

s3.headObject(params, function(err, data) {
    if (err) console.log(err, err.stack);  // an error occurred
    else     console.log(data);            // successful response
});

In this code, s3.headObject(params, ...) is used to retrieve the metadata of an object. The data object in the callback will contain a Metadata field that contains the metadata of the object.

Remember to replace 'YOUR_ACCESS_KEY', 'YOUR_SECRET_KEY', 'your-bucket-name', and 'your-object-key' with your own values. The 'your-object-key' is the file name in the bucket.

Note: AWS SDK uses the us-east-1 region by default. Since DigitalOcean Spaces doesn’t use AWS regions, you can put any string there when configuring the AWS SDK, but it cannot be left blank.

Best,

Bobby
