go-aws-commons - JakartaCommons meets Go, for lack of better naming

My multi-module workspace to make working with AWS services easier. See also:

• github.com/nguyengg/go-to: mixed bag of Go utility packages.
• github.com/nguyengg/gin-seng: Gin middlewares and helper methods.

Available as their own module:

• config-cache (configcache): single AWS config cache to make using package-level methods easier.
• ddb-mapper: add optimistic locking and auto-generated timestamps via struct tags.
  • gin-sessions: replaces github.com/gin-contrib/sessions with ddb-mapper integration.
• gin-caching-response-headers (cachingheaders): sets caching response headers (Cache-Control, ETag, and/or Last-Modified) on the gin response.
• gin-json-abort (abort): provides package-level methods to help abort a gin request using JSON response as well as logging.
• gin-metrics (ginmetrics): replaces gin.Logger and gin.Recovery with metrics.Metrics integration.
• gin-preconditions (preconditions): provides helper methods to parse and compare conditional headers such as If-Match, If-None-Match, If-Modified-Since, and If-Unmodified-Since.
• gin-s3-proxy (proxy): a very simple Gin middleware acting as an S3 proxy.
• lambda: Lambda handler wrappers with sensible defaults and metrics integration.
  • function-url (functionurl): provides Lambda wrappers for Function URL gin handlers in either BUFFERED or STREAMING mode.
  • getenv: decouple how to retrieve a variable of any type (usually string or binary) via AWS Parameter Store and Secrets Lambda extension.
• metrics: logging latency metrics and other custom counters.
• opaque-token (token): convert DynamoDB last evaluated key to opaque token; create and validate CSRF tokens.
• s3reader: implements io.ReadSeeker, io.ReaderAt, and io.WriterTo using S3 ranged GetObject.
• s3writer: implements io.Writer and io.ReaderFrom for uploading to S3.
• scale-in-protection (sip): protect EC2 AutoScaling instances from being scaled down while busy.
• slogging: attach/retrieve to/from context; JSON and error (with stack trace) slog.Value implementations.
• sri: Subresource Integrity (SRI) computation and verification.
• tspb: Terminal-Safe Progress Bar (TSPB); when you want your program to show progress bar in interactive mode (with terminal), but log normally otherwise.

Available as package in this module (commons):

• args: iterator to scan text lines from multiple sources.
• errors: convenient methods to extract status code and other metadata from AWS errors.
• executor: Java's Executor for Go.
• fmt: provides fmt.Formatter implementations for printing/logging any data as JSON.
• must: for when you're tired of typing if a, err := someFunction(); err != nil and just want to panic instead.
