AWS S3 is an object storage service that allows you to store and serve large amounts of data.

You can upload files to S3 using the AWS Management Console, AWS CLI, or SDKs.

S3 buckets are the primary containers that hold your data, and you can create up to 100 buckets per AWS account.

Each S3 bucket can store up to 5 TB of data.

To upload files to S3, you need to create an S3 bucket first.

Setting Up AWS S3

To set up AWS S3, you'll first need to create an IAM user with access to Amazon S3, which involves creating an IAM user with the AmazonS3FullAccess policy attached.

You'll also need to create an S3 bucket, which is a container for storing objects, such as files, in the Amazon S3 cloud. To create an S3 bucket, log in to your AWS account and navigate to the S3 console, then click on the "Create bucket" button.

To access your AWS account programmatically, you'll need to provide your access keys to the AWS SDK, which can be obtained from the AWS console by following the steps outlined in the IAM console.

Here are the details required to set up an AWS CLI profile on your computer:

  • The Access key ID of the IAM user.
  • The Secret access key associated with the IAM user.
  • The Default region name is corresponding to the location of your AWS S3 bucket.
  • The default output format, which should be JSON.

Create a Bucket

To create a bucket in AWS S3, you'll need to log in to your AWS account and navigate to the S3 console. Click on the "Create bucket" button to start the process.

You can choose a unique name for your bucket, which will be used as AWS_S3_BUCKET_NAME in your application. For example, you could name it "my-custom-bucket-0".

In the Policy section, you'll need to define the actions allowed with the bucket using JSON. This will determine what actions can be performed on your bucket, such as reading or writing objects.

You can complete the bucket creation process by clicking the "Create bucket" button at the end. This will create the bucket in the region you selected, with the default settings for versioning, logging, and permissions.

Here are the basic steps to create a bucket in AWS S3:

  1. Log in to your AWS account and navigate to the S3 console.
  2. Click on the “Create bucket” button.
  3. Enter a unique name for your bucket and select a region.
  4. Choose the default settings for versioning, logging, and permissions.
  5. Click on the “Create bucket” button to create the bucket.

Setting Up a Profile

To set up a profile for AWS, you'll need to have an AWS account with access keys, which can be obtained by signing up for an AWS Free Tier. You'll also need to install the AWS CLI version 2 tool on your computer.

To create the profile, you'll need to provide the Access key ID, Secret access key, Default region name, and default output format. The Default region name corresponds to the location of your AWS S3 bucket, which can be found using this link. You can also use the Asia Pacific (Sydney) region, which has the corresponding endpoint ap-southeast-2.

You can create the profile by opening PowerShell and typing the command below, following the prompts to enter the required information. The default output format should be set to JSON.

Here are the details you'll need to provide:

  • Access key ID
  • Secret access key
  • Default region name
  • Default output format (JSON)

Make sure to keep your access keys safe, as they can be used to access your AWS account programmatically.

Configuration Options

As you set up your AWS S3 account, you'll want to configure the Uploader instance to suit your needs. You can specify several configuration options to customize how objects are uploaded.

The PartSize option is particularly useful, as it specifies the buffer size, in bytes, of each part to upload. The minimum size per part is 5 MiB.

To optimize your uploads, you can tweak the PartSize and Concurrency configuration values. For example, systems with high-bandwidth connections can send bigger parts and more uploads in parallel.

The Concurrency value limits the concurrent number of part uploads that can occur for a given Upload call. This is not a global client concurrency limit.

Here are the configuration options you can specify when creating an Uploader instance:

By understanding these configuration options, you can tailor your Uploader instance to meet your specific needs and optimize your uploads.

Uploading Files

You can upload files to S3 using the AWS SDK for JavaScript. To do this, you need to create a new object in your S3 bucket and upload the file data to it.

The AWS SDK's S3 API provides a simple function for uploading a file to Amazon S3. This function takes two parameters: the local file to be uploaded and the destination S3 bucket.

You can also use presigned URLs to upload large chunks of data directly at the source. This saves you from maximum request payload restrictions and huge RAM requirements.

To create a presigned URL, you can create an API endpoint that accepts the file name and its content type. In Next.js, you can create an API endpoint by creating a route.ts file at any directory level inside the app directory.

Here are the configuration options you can specify when instantiating an Uploader instance:

  • PartSize – Specifies the buffer size, in bytes, of each part to upload. The minimum size per part is 5 MiB.
  • Concurrency – Specifies the number of parts to upload in parallel.
  • LeavePartsOnError – Indicates whether to leave successfully uploaded parts in Amazon S3.

You can also use the aws s3 cp command to upload files to S3 recursively. The --recursive option allows you to upload all the contents of a folder and sub-folders to S3 while retaining the folder structure.

You can also use the --include and --exclude options to selectively upload files to S3. For example, you can include only files with specific file extensions, such as *.ps1.

The Concurrency value limits the concurrent number of part uploads that can occur for a given Upload call. This is not a global client concurrency limit.

Managing Files

Managing files in AWS S3 is a breeze, especially with the right tools and commands. You can upload files one at a time or recursively upload multiple files and folders, depending on your requirements.

To upload a file to S3, you can use the AWS SDK's S3 API in NodeJS, as shown in Example 2. This involves creating a new object in your S3 bucket and uploading the file data to it.

You can also manage files using the AWS CLI, which allows you to perform typical file management operations like uploading, downloading, deleting, and copying S3 objects. For instance, you can upload files to S3 using the `aws s3 cp` command, as demonstrated in Example 3.

To upload a folder to S3, you can use the `aws s3 sync` command, which recursively gathers a list of files and uploads them to the specified Amazon S3 bucket. The keys of the Amazon S3 objects are prefixed with the file's relative path, as shown in Example 4.

Here are some common file management operations you can perform with the AWS CLI:

  • Upload files to S3 using `aws s3 cp`
  • Download files from S3 using `aws s3 cp`
  • Delete objects in S3 using `aws s3 rm`
  • Copy S3 objects to another S3 location using `aws s3 cp`

You can also use the `aws s3 sync` command to synchronize files and folders between a local directory and an S3 bucket. This command only processes updated, new, and deleted files, as shown in Example 5.

Troubleshooting

Troubleshooting can be a frustrating process, but knowing where to look can make all the difference. If you're experiencing issues with your AWS S3 upload, check the bucket policy to ensure it allows the necessary permissions.

Make sure your AWS credentials are correct, as incorrect credentials can cause upload failures. I've seen it happen to the best of us.

If you're still having trouble, try checking the bucket's CORS configuration. In our previous example, we set the CORS configuration to allow cross-origin requests.

Slow Speeds

If you're experiencing slow speeds, consider checking your internet connection for optimal performance.

Amazon S3 Transfer Acceleration can be a game-changer for faster uploads.

Slow upload speeds can be a major issue, but using Amazon S3 Transfer Acceleration can help resolve the problem.

This feature can significantly improve upload speeds, making it a worthwhile solution to consider.

In some cases, switching to a different AWS region might also help improve performance.

Handling Failed

Handling failed uploads can be a real challenge, especially when you're working with large files. By default, Uploader uses the Amazon S3 AbortMultipartUpload operation to remove the uploaded parts, which ensures that failed uploads don't consume Amazon S3 storage.

This functionality is a lifesaver, as it prevents your storage from getting cluttered with incomplete uploads. You can set LeavePartsOnError to true, so that the Uploader doesn't delete successfully uploaded parts, which is useful for resuming partially completed uploads.

To operate on uploaded parts, you'll need to get the UploadID of the failed upload. The manager.MultiUploadFailure error interface type provides this information, as shown in the example.

Frequently Asked Questions

What is the difference between Put_object and upload_file?

For uploading files to an S3 bucket, use upload_file for simple APIs or large files (>5GB), or put_object for additional configurability, such as setting object ACLs. Choose the method that best fits your specific use case.

What is the fastest way to upload many files to S3?

For large file uploads, use multipart uploads or leverage high-level AWS CLI commands like aws s3 cp and aws s3 sync, which automatically perform multipart uploads. This approach significantly speeds up the upload process for many files to S3.

How can I upload a file to S3 without creating a temporary local file?

To upload a file to S3 without creating a temporary local file, you can use the `BytesIO` class to read the file into memory and then upload it directly to S3 using the `boto3` library. This approach allows for efficient file uploads without the need for intermediate storage.
