1 | # Go micro-service in ~30 minutes
2 |
3 | This is a Go micro-service written from scratch.
4 |
5 | It shows how to use [net/http](https://godoc.org/net/http), and how to structure a Go project.
6 |
7 | It relies on Go 1.11 Beta 2 and the upcoming "Go modules" (formerly known as "vgo") support.
8 |
9 | Dependency injection is used to insert a logger instance into the handler.
10 |
11 | You can also notice how the test is constructed in order to provide testing for the handler.
12 |
13 | A Docker container is available, thanks to the Dockerfile. It shows how to construct such containers.
14 |
15 | ## How to use
16 |
17 | Because this project uses go modules, as long as you are using Go 1.11 Beta 2+ or Go 1.10 with vgo support,
18 | you should be ok.
19 |
20 | Clone this anywhere in your computer and create a project in your editor. I'm using [GoLand IDE](https://jetbrains.com/go) in order to work
21 | on the project during the presentation as well as have support for go modules.
22 |
23 | The bundled, self-signed, certificates are bound to either ` dev.localhost:8080 ` or ` docker.localhost:8080 `. I obviously
24 | do not recommend using these in production.
25 |
26 | ## Presentation link
27 |
28 | I created this as part of the presentation at [GopherCon UK 18](https://www.gophercon.co.uk/).
29 |
30 | The link for the video will be updated here when the presentation is out.

34 | ### Structuring Go applications
35 |
36 | In order to learn how to approach package design in Go, you can read the following resources:
37 |
38 | - [Style guideline for Go packages - JBD](https://rakyll.org/style-packages/)
39 | - [Standard Package Layout - Ben Johnson](https://medium.com/@benbjohnson/standard-package-layout-7cdbc8391fc1#.ds38va3pp)
40 | - [Go best practices, six years in - Peter Bourgon](https://peter.bourgon.org/go-best-practices-2016/#repository-structure)
41 |
42 | Once done, this article will help you understand the [Design Philosophy On Packaging by William Kennedy](https://www.ardanlabs.com/blog/2017/02/design-philosophy-on-packaging.html).

44 | ### Exposing Go applications to the Internet

46 | [This article](https://blog.cloudflare.com/exposing-go-on-the-internet/) describes how you can start approaching

48 | ## Thank you
49 |
50 | I would like to thank you [William "Bill" Kennedy](https://twitter.com/goinggodotnet) for the inspiration he provided on
51 | getting me to do this talk.
