Modern Go Application

Go application boilerplate and example applying modern practices

This repository tries to collect the best practices of application development using Go language. In addition to the language specific details, it also implements various language independent practices.

Some of the areas Modern Go Application touches:

• architecture
• package structure
• building the application
• testing
• configuration
• running the application (eg. in Docker)
• developer environment/experience
• telemetry

To help adopting these practices, this repository also serves as a boilerplate for new applications.

Features

• configuration (using spf13/viper)
• logging (using logur.dev/logur and sirupsen/logrus)
• error handling (using emperror.dev/emperror)
• metrics and tracing using Prometheus and Jaeger (via OpenCensus)
• health checks (using AppsFlyer/go-sundheit)
• graceful restart (using cloudflare/tableflip) and shutdown
• support for multiple server/daemon instances (using oklog/run)
• messaging (using ThreeDotsLabs/watermill)
• MySQL database connection (using go-sql-driver/mysql)
• Redis connection (using gomodule/redigo) removed due to lack of usage (see #120)

First steps

To create a new application from the boilerplate clone this repository (if you haven't done already) into your GOPATH then execute the following:

chmod +x init.sh && ./init.sh
? Package name (github.com/sagikazarmark/modern-go-application)
? Project name (modern-go-application)
? Binary name (modern-go-application)
? Service name (modern-go-application)
? Friendly service name (Modern Go Application)
? Update README (Y/n)
? Remove init script (y/N) y

It updates every import path and name in the repository to your project's values. Review and commit the changes.

Load generation

To test or demonstrate the application it comes with a simple load generation tool. You can use it to test the example endpoints and generate some load (for example in order to fill dashboards with data).

Follow the instructions in etc/loadgen.
