• Example of GitHub web login

The latest version of Kitura-CredentialsGitHub requires Swift 4. You can download this version of the Swift binaries by following this link. Compatibility with other Swift versions is not guaranteed.

This guide assumes basic knowledge of Kitura app routing.

First, set up the session middleware:

import KituraSession

router.all(middleware: Session(secret: "Very very secret..."))

Create an instance of CredentialsGitHub plugin and register it with Credentials framework:

import Credentials
import CredentialsGitHub

let credentials = Credentials()
let gitCredentials = CredentialsGitHub(clientId: gitClientId, clientSecret: gitClientSecret, callbackUrl: serverUrl + "/login/github/callback", userAgent: "my-kitura-app", options: ["scopes": ["user:email"]])
credentials.register(gitCredentials)

Where:

• gitClientId is the Client ID of your app in your GitHub Developer application settings
• gitClientSecret is the Client Secret of your app in your GitHub Developer application settings
• callbackUrl is used to tell the GitHub web login page where the user's browser should be redirected when the login is successful. It should be a URL handled by the server you are writing.
• userAgent is an optional argument that passes along a User-Agent of your choice on API calls against GitHub. By default, Kitura-CredentialsGitHub is set as the User-Agent. User-Agent is required when invoking GitHub APIs.
• options is an optional dictionary ([String: Any]); the allowable options are listed in CredentialsGitHubOptions

Next, specify where to redirect non-authenticated requests:

credentials.options["failureRedirect"] = "/login/github"

Connect credentials middleware to handle requests to a protected path on the server, such as /private:

router.all("/private", middleware: credentials)
router.get("/private/data", handler: { request, response, next in
  ...  
  next()
})

And call authenticate to login with GitHub and to handle the redirect (callback) from the GitHub login web page after a successful login:

router.get("/login/github", handler: credentials.authenticate(gitCredentials.name))

router.get("/login/github/callback", handler: credentials.authenticate(gitCredentials.name))
