S3.js Code Examples
Ready-to-use code samples demonstrating common S3.js workflows
File Upload Example
const s3 = createS3Client({
region: 'us-east-1',
accessKeyId: 'YOUR_ACCESS_KEY',
secretAccessKey: 'YOUR_SECRET_KEY'
});
const uploadResult = await s3.upload({
Bucket: 'my-bucket',
Key: 'photos/test.jpg',
Body: fileInput.files[0],
ContentType: 'image/jpeg'
});
Bucket Object List
// Browser version with async/await
const objects = await s3.listObjects({
Bucket: 'my-bucket',
Prefix: 'photos/'
});
// Node.js example with promises
s3.listObjects({
Bucket: 'my-bucket',
Prefix: 'documents/'
})
.promise()
.then(data => console.log(data));
