Goth-Fiber: Multi-Provider Authentication for Go

Is wrapper for goth library to use with fiber Framework, provides a simple, clean, and idiomatic way to write authentication packages for Go web applications.

Unlike other similar packages, Goth, lets you write OAuth, OAuth2, or any other protocol providers, as long as they implement the Provider and Session interfaces.

Examples

See the examples folder for a working application that lets users authenticate through Twitter, Facebook, Google Plus etc.

To run the example either clone the source from GitHub

$ git clone git@github.com/shareed2k/goth_fiber.git

$ go get github.com/shareed2k/goth_fiber

$ cd goth_fiber/examples
$ go get -v
$ go build
$ ./examples

Now open up your browser and go to http://localhost:8088/login/google to see the example.

To actually use the different providers, please make sure you set environment variables. Example given in the examples/main.go file

Security Notes

By default, goth_fiber uses a Session from the gofiber/session package to store session data.

As configured, goth will generate cookies with the following session.Config:

    session.Config{
	    Expiration: 24 * time.Hour,
	    Storage:    memory.New(),
	    KeyLookup: "cookie:_gothic_session",
	    CookieDomain: "",
	    CookiePath: "",
	    CookieSecure: false,
	    CookieHTTPOnly: true,
	    CookieSameSite: "Lax",
	    KeyGenerator: utils.UUIDv4,
	}

To tailor these fields for your application, you can override the goth_fiber.SessionStore variable at startup.

The following snippet shows one way to do this:

    // optional config
    config := session.Config{
	    Expiration:     30 * time.Minutes,
	    Storage:        sqlite3.New(), // From github.com/gofiber/storage/sqlite3
	    KeyLookup:      "header:session_id",
	    CookieDomain:   "google.com",
	    CookiePath:     "/users",
	    CookieSecure:   os.Getenv("ENVIRONMENT") == "production",
	    CookieHTTPOnly: true, // Should always be enabled
	    CookieSameSite: "Lax",
	    KeyGenerator:   utils.UUIDv4,
	}

    // create session handler
    sessions := session.New(config)

    goth_fiber.SessionStore = sessions
