Look inside

Echorand Corp., a growing analytics company, uses the GitHub hosting service for its software hosting and collaboration needs. But the company has received feedback voicing concerns about the service’s lack of backup functionality. As a software engineer, it’s up to you to solve this problem. You’ll use Go to build a web application that allows users to log in using their GitHub credentials and access the GitHub API using OAuth authorization. You’ll create HTTP client middleware for writing and performing tests with no need to interact with Github.com, and you’ll write automated tests that enable you to update the application while speeding up the development cycle. When you’re done, you’ll have built an easy-to-update application that allows users to log in with their GitHub credentials.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

prerequisites

This liveProject is for beginner-level Go programmers interested in learning to build a web application that allows users to sign in with their GitHub credentials. To begin these liveProjects you’ll need to be familiar with the following:

TOOLS
  • Key Go standard library packages: net/http, net/http/cookiejar, net/http/httptest, testing
  • Third-party packages: https://golang.org/x/oauth2 and github.com/google/go-github
  • HTTP cookies (for maintaining state on the client side)
  • Understanding of how HTTP applications work (concepts including request routing, cookie handling, and redirects)
TECHNIQUES
  • Language basics: writing functions, creating structures, conditional statements, standard input and output, and basic understanding of interfaces
  • Packaging basics: what a module is and using sub-packages
  • Go commands: go build and go test
