Buffalo GoDoc Build Status Code Climate Go Report Card

Buffalo is a Go web development eco-system. Designed to make the life of a Go web developer easier.

Buffalo starts by generating a web project for you that already has everything from front-end (JavaScript, SCSS, etc...) to back-end (database, routing, etc...) already hooked up and ready to run. From there it provides easy APIs to build your web application quickly in Go.

Buffalo isn't just a framework, it's a holistic web development environment and project structure that lets developers get straight to the business of, well, building their business.

Documentation

Please visit http://gobuffalo.io for the latest documentation, examples, and more.

Installation

$ go get -u -v github.com/gobuffalo/buffalo/buffalo

NOTE: Buffalo has a minimum Go dependency of 1.8.1.

Buffalo also depends on:

  • gcc for go-sqlite3 which is a cgo package.
  • node and npm for the asset pipeline.

Generating a new Project

Buffalo aims to make building new web applications in Go as simple as possible, and what could be more simple than a new application generator?

$ buffalo new <name>

That will generate a whole new Buffalo application that is ready to go. It'll even run go get for you to make sure you have all of the necessary dependencies needed to run your application.

To see a list of available flags for the new command, just check out its help.

$ buffalo help new

Running your application

Buffalo is Go "standards" compliant. That means you can just build your binary and run it. It's that simple.

Running your application in Development

One of the downsides to Go development is the lack of code "reloading". This means as you change your code you need to manually stop your application, rebuild it, and then restart it. Buffalo finds this is annoying and wants to make life better for you.

$ buffalo dev

The dev command will watch your .go and .html files by default, rebuild, and restart your binary for you so you don't have to worry about such things. Just run the dev command and start coding.

Testing your application

Just like running your application, Buffalo doesn't stop you from using the standard Go tools for testing. Buffalo does ship with a test command that will run all of your tests while conveniently skipping that pesky old ./vendor directory!

$ buffalo test

Shoulders of Giants

Buffalo would not be possible if not for all of the great projects it depends on. Please see SHOULDERS.md to see a list of them.

Templating

github.com/gobuffalo/plush - This templating package was chosen over the standard Go html/template package for a variety of reasons. The biggest of which is that it is significantly more flexible and easy to work with.

Routing

github.com/gorilla/mux - This router was chosen because of its stability and flexibility. There might be faster routers out there, but this one is definitely the most powerful!

Task Runner (Optional)

github.com/markbates/grift - If you're familiar with Rake tasks from Ruby, you'll be right at home using Grift. This package was chosen to allow for the easy running of simple, and common, tasks that most web applications need. Think things like seeding a database or taking in a CSV file and generating database records. Buffalo ships with an example routes task that prints off the defined routes and the function that handles those requests.

Models/ORM (Optional)

github.com/markbates/pop - Accessing databases is nothing new in web applications. Pop, and its command line tool, Soda, were chosen because they strike a nice balance between simplifying common tasks, being idiomatic, and giving you the flexibility you need to built your app. Pop and Soda share the same core philosphies as Buffalo so they were a natural choice.

Sessions, Cookies, Websockets, and more...

github.com/gorilla - The Gorilla toolkit is a great set of packages designed to improve upon the standard libary for a variety of web-related packages. With these high quality packages Buffalo is able to keep its "core" code to a minimum and focus on its goal of glueing them all together to make your life better.

Benchmarks

Oh, yeah, everyone wants benchmarks! What would a web framework be without its benchmarks? Well, guess what? I'm not giving you any! That's right. This is Go! I assure you that it is plenty fast enough for you. If you want benchmarks you can either a) checkout any benchmarks that the GIANTS Buffalo is built upon have published, or b) run your own. I have no interest in playing the benchmark game, and neither should you.

var RequestLogger = RequestLoggerFunc

RequestLogger can be be overridden to a user specified function that can be used to log the request.

Functions

func Grifts added in v0.9.1 

func Grifts(app *App)

Grifts decorates the app with tasks

func MethodOverride 

func MethodOverride(res http.ResponseWriter, req *http.Request)

MethodOverride is the default implementation for the Options#MethodOverride. By default it will look for a form value name `_method` and change the request method if that is present and the original request is of type "POST". This is added automatically when using `New` Buffalo, unless an alternative is defined in the Options.

Types

type App 

type App struct {
	Options
	// Middleware returns the current MiddlewareStack for the App/Group.
	Middleware    *MiddlewareStack
	ErrorHandlers ErrorHandlers
	// contains filtered or unexported fields
}

App is where it all happens! It holds on to options, the underlying router, the middleware, and more. Without an App you can't do much!

func New 

func New(opts Options) *App

New returns a new instance of App and adds some sane, and useful, defaults.

func (*App) ANY 

func (a *App) ANY(p string, h Handler)

DELETE maps an HTTP "DELETE" request to the path and the specified handler.

func (*App) GET 

func (a *App) GET(p string, h Handler) *RouteInfo

GET maps an HTTP "GET" request to the path and the specified handler.

func (*App) Group 

func (a *App) Group(groupPath string) *App

Group creates a new `*App` that inherits from it's parent `*App`. This is useful for creating groups of end-points that need to share common functionality, like middleware. 

g := a.Group("/api/v1")
g.Use(AuthorizeAPIMiddleware)
g.GET("/users, APIUsersHandler)
g.GET("/users/:user_id, APIUserShowHandler)

	f := func(res http.ResponseWriter, req *http.Request) {
		fmt.Fprintf(res, "%s - %s", req.Method, req.URL.String())
	}
	mux := mux.NewRouter()
	mux.HandleFunc("/foo", f).Methods("GET")
	mux.HandleFunc("/bar", f).Methods("POST")
	mux.HandleFunc("/baz/baz", f).Methods("DELETE")
	return mux
}

a.Mount("/admin", muxer())

$ curl -X DELETE http://localhost:3000/admin/baz/baz

func (*App) PanicHandler added in v0.8.2 

func (a *App) PanicHandler(next Handler) Handler

PanicHandler recovers from panics gracefully and calls the error handling code for a 500 error.

func (*App) Redirect added in v0.7.3 

func (a *App) Redirect(status int, from, to string) *RouteInfo

func (*App) Resource added in v0.4.3 

func (a *App) Resource(p string, r Resource) *App

Resource maps an implementation of the Resource interface to the appropriate RESTful mappings. Resource returns the *App associated with this group of mappings so you can set middleware, etc... on that group, just as if you had used the a.Group functionality. 

a.Resource("/users", &UsersResource{})

// Is equal to this:

ur := &UsersResource{}
g := a.Group("/users")
g.GET("/", ur.List) // GET /users => ur.List
g.GET("/new", ur.New) // GET /users/new => ur.New
g.GET("/{user_id}", ur.Show) // GET /users/{user_id} => ur.Show

}

Resource interface allows for the easy mapping of common RESTful actions to a set of paths. See the a.Resource documentation for more details. NOTE: When skipping Resource handlers, you need to first declare your resource handler as a type of buffalo.Resource for the Skip function to properly recognize and match it. 

// Works:
var cr Resource
cr = &carsResource{&buffaloBaseResource{}}
g = a.Resource("/cars", cr)
g.Use(SomeMiddleware)
g.Middleware.Skip(SomeMiddleware, cr.Show)
