# storage
|
|
|
|
Standalone Go library for AWS S3 storage operations.
|
|
|
|
**Note:** This is an independent library, not part of the Shiny ecosystem, though it is currently only used by Shiny services.
|
|
|
|
## Purpose
|
|
|
|
Provides standardized S3 object storage utilities with presigned URL generation. Used by services that need to store and serve files (PDFs, images, etc.).
|
|
|
|
## Usage
|
|
|
|
```go
|
|
import "gitlab.com/unboundsoftware/storage"
|
|
|
|
// Option 1: Managed uploads (multipart, 5MB part size) - loads AWS config automatically
|
|
s3Storage, err := storage.New("my-bucket")
|
|
|
|
// Option 2: Direct uploads with custom AWS config
|
|
cfg, _ := config.LoadDefaultConfig(context.Background())
|
|
s3Storage := storage.NewS3(cfg, "my-bucket")
|
|
|
|
// Upload and get presigned URL (15-minute expiration)
|
|
url, err := s3Storage.Store("path/to/file.pdf", reader, "application/pdf")
|
|
```
|
|
|
|
## Features
|
|
|
|
- **Managed uploads** (`New`) - Uses upload manager with 5MB multipart chunks for large files
|
|
- **Direct uploads** (`NewS3`) - Uses PutObject directly, allows custom AWS config
|
|
- **Presigned URLs** - 15-minute expiration for secure access
|
|
|
|
## Configuration
|
|
|
|
Uses AWS SDK v2, loading config from:
|
|
- Environment variables (`AWS_REGION`, `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`)
|
|
- Shared config files (`~/.aws/config`, `~/.aws/credentials`)
|
|
- IAM roles (on AWS infrastructure)
|
|
|
|
## Development
|
|
|
|
- Go 1.23+
|
|
- Run tests: `go test ./...`
