• Echo

  123 28,593 8.0 Go

  High performance, minimalist Go web framework

  

For REST http i used echo, another good popular choice on my opinion is gin, and swag for generate RESTful API documentation. Create email handler accept requests, start tracing span, validate input using validator and call usecase method:

• prometheus

  383 52,933 9.9 Go

  The Prometheus monitoring system and time series database.

• Gin

  152 75,668 8.5 Go

  Gin is a HTTP web framework written in Go (Golang). It features a Martini-like API with much better performance -- up to 40 times faster. If you need smashing performance, get yourself some Gin.

• go-simple-mail

  5 603 6.0 Go

  Golang package for send email. Support keep alive connection, TLS and SSL. Easy for bulk SMTP.

MailHog is good solution for email testing, and for go smtp client here used go-simple-mail.

• retry-go

  5 2,232 6.2 Go

  Simple golang library for retry mechanism

  

processCreateEmail handling create email events, it's start tracing span, increase metrics counters, then unmarshal message data, and call usecase create method, if it fails, we retry for 3 times using retry-go, if it still fails, we check is the current message redelivered and if redelivery count > maxRedeliveryCount(it's up to your business logic, here is 3 times limit), handling error cases can be very different and depends on your service business logic, in this example used Dead Letter Queue approach.

• Grafana

  380 60,503 10.0 TypeScript

  The open and composable observability and data visualization platform. Visualize metrics, logs, and traces from multiple sources like Prometheus, Loki, Elasticsearch, InfluxDB, Postgres and many more.
