Go for Real World Applications

Go is a powerful backend language that is an asset to any developer's toolkit. It is extremely performant, a relatively easy language in terms of syntax, and has many valuable features like testing and JSON serialization and deserialization built in.  In this practical, hands-on, step-by-step style book, we'll build a fully functioning Go application from complete scratch along these steps:

- Scaffolding the Go application and writing main.go

- Writing cron jobs in Go

- Writing a powerful generic HTTP function

- Using that HTTP function to call an API and serialize the response into Go object's using Go

- Use that HTTP function to POST messages to a Slack channel

- Write tests using Go's built in testing module

- Dockerize the application so that it can be run with docker compose

- Round off the course by crafting a complete CI/CD pipeline that first builds and tests our application, then Dockerizes and uploads the application to Docker Hub

- We'll see that once the Circle CI pipeline is setup, we can control the entire pipeline process through pushing to a git branch alone, and never have to manually do any sort of configuration or commands for our deploys

By the end of the course, you will have the confidence and know how to build Go applications from start to finish - including testing, Dockerizing, and deploying them!
