  1. 01 coreruntime A global factory context that wires up your logger, databases, Redis, and whatever else you need, all with W3C trace contexts baked in from the start. Traces get collected and shipped off to App Insights or Jaeger without you having to think about it.
  2. 02 aych An HTTP client builder for Go that lets you construct requests in a chainable, readable way instead of wrestling with the standard library every time you need to set a header or serialize a body.
  3. 03 squeel A thin wrapper around Go's database/sql that adds middleware support — think interceptors, logging, tracing — without pulling in a full ORM and all the opinions that come with it.
  4. 04 cafe Define the env configuration you want for your app and cafe will load it for you with support for defaults, overrides, and environment variables.
  5. 05 eventually Reactive event streams for Go, heavily inspired by RxJS. Subscribe, map, filter, and compose async data flows without the callback soup.
  6. 06 nselastic A queryable SDK around Elasticsearch that gets rid of the boilerplate JSON queries you have to write every single time. Just describe what you want and let it handle the DSL.
  7. 07 go-test Spins up dockerized instances of Postgres, Redis, or RabbitMQ for your Go tests and tears them down when you're done. No more mocks for things that shouldn't be mocked.
  8. 08 tern Ternary expressions for Go. Because it looks prettier than writing a four-line if-else statement
