# Go Fiber Firebase Auth Middleware
[](https://circleci.com/gh/sacsand/gofiber-firebaseauth)
Authenticate your endpoints with [Firebase Authentication ](https://github.com/LeafyCode/express-firebase-auth/).
gofiber-firebaseauth is inspired by npm package [express-firebase-auth](https://github.com/LeafyCode/express-firebase-auth/) .
#### Note1
This package is designed to work with [Go Fiber Framework](https://github.com/gofiber/fiber) (Express inspired go framework)
# Features
- Authenticate the user using Firebase before running the function.
- Ability to skip authentication on public API endpoints.
# Installing / Getting started
In your gofiber app
```sh
$ go get -u github.com/gofiber/fiber/v2
$ go get github.com/sacsand/gofiber-firebaseauth
```
# Configure
In your app import the middleware
```go
import (
"github.com/gofiber/fiber/v2"
"github.com/sacsand/gofiber-firebaseauth"
)
```
Provide a minimal config
```go
// Provide a minimal config
app.Use(gofiberfirebaseauth.New(Config{
FirebaseApp: FirebaseApp,
}))
```
Or extend your config for customization
```go
// Or extend your config for customization
app.Use(gofiberfirebaseauth.New(Config{
// New firebase authentication object
// Mandatory. Default: nil
FirebaseApp: FirebaseApp
// Ignore urls array - Format = "{METHOD} follwed by :: then /{route}"
// Optional. Default: nil
IgnoreUrls : []string{"GET::/login","POST::/create-user"}
// Skip Email Check.
// Optional. Default: nil
CheckEmailVerified : true
// Ignore email verification for these routes
// Optional. Default: nil
CheckEmailVerifiedIgnoredUrls : []string{"GET::/login","POST::/create-user"}
// Authorizer defines a function which authenticates the Authorization token and returns
// the authenticated token
// Optional. Default: nil
Authorizer: func(IDToken string, CurrentURL string) (*auth.Token, error){
// create your own authentication here
// this returns the firebase id token
return token, nil
},
// Context key to store user information from the token into context.
// Optional. Default: "user".
ContextKey : "authUser"
}))
```
Use user in your fiber app
```go
func Handler(ctx *fiber.Ctx) error {
// Get user stored in context
// Default: user
currentUser := ctx.Locals("user").(gofiberfirebaseauth.User)
fmt.Println(currentUser)
fmt.Println(currentUser.Email)
}
```
All available configuration
| Option | Value | Config type |
| ------------------------------- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------: | :--------------------------------------------------- |
| `FirebaseApp` | ([**Note1**](#note2)) An initialized firebase app. [Refer to Firebase setup](https://firebase.google.com/docs/admin/setup) | FirebaseApp *firebase.App |
| `IgnoredUrls` | ([**Note1**](#note3))(*Optional*) An array of URLs where you need to skip the authentication. | IgnoreUrls []string |
| `CheckEmailVerified` | (*Optional*) (Default: **false**) If set to **true**, only users with a verified email will be allowed access. | CheckEmailVerified bool |
| `CheckEmailVerifiedIgnoredUrls` | (*Optional*) An array of URLs where you need to skip the email verified check. | CheckEmailVerifiedIgnoredUrls []string |
| `Authorizer` | (*Optional*), Default: nil , Authorizer defines a function which authenticates the Authorization token and returns the authenticated token. Use this if you want to override token authorization | Authorizer func(string, string) (*auth.Token, error) |
| `ContextKey` | (*Optional*), Default: "user" , Context key to store user information from the token into context. | ContextKey string |
| `SuccessHandler` | (*Optional*), Default:nil, SuccessHandler defines a function which is executed for a valid token. | SuccessHandler fiber.Handler |
| `ErrorHandler` | (*Optional*), Default:nil, ErrorHandler defines a function which is executed for a invalid token. | ErrorHandler fiber.ErrorHandler |
#### Note2
You **must** provide already initialized `FirebaseApp` app.
You cannot initialize two firebase apps.
#### Note3
Ignore url accept array of string. URl format should follow below format\
`{METHOD}::/{url}`\
Example: \
GET::/login\
POST::/login
IgnoreUrl only supports routes without params or query . (PR are welcome).To ignore urls with param or query, declare the routes before the middleware declaration.
## Developing , TESTING and environment setup
### Prerequisites
- Go 1.14 +
- Configured Firebase app and Google Service Account Credential (JSON containing admin credentials). Refer to [Firebase setup](https://firebase.google.com/docs/admin/setup)
- Web API Key
- Sample user email and password from firebase. You can manually create a user from the firebase console.
You can get all the configurations from Firebase Console.
### Setting up Development Environment for testing
Clone the repo and set your firebase credentials in your .env file
```
SERVICE_ACCOUNT_JSON = "path to service account credential json"
WEB_API_KEY =
TEST_USER_EMAIL = ""
TEST_USER_PASSWORD = ""
```
