Go lang web app "framework" showcasing straightforward, no-magic, web development with the Go language. Includes batch template processing and interaction with postgresql databases, and Model-View architecture.

Quick Start

• Make sure your GOPATH and GOROOT are set.
  • For help, run go help gopath
• ./install
• ./run
  • this performs the following commands:
  • go build
  • ./Gooo

Philosophy

• Anti-magic
• So simple, that it's complex.
• So complex, that it works.
• If it doesn't work, publish it.

Modular architecture

• model
  • struct type
  • no special tags or fields, models are just Go structs
  • business logic - straightforward DB methods to be used in the view module
• view
• parses templates in tmpl/ folder and defines how they are rendered
• uses html/template to parse and render
• fetches rows from database as type Model interfaces
• router
  • handles dynamic and static routes, request methods, main handler matches the request URL against the routes
  • middleware filters for restful routes
• introspection
  • models implement interface{} and []interface{} types
  • Go's dynamic feature is interface type conversion, generally checked at runtime
  • Interface -> JSON interface{} -> []byte
  • Interface -> Struct []interface{} -> map[string]interface{}
  • GetStructValues interface{} -> []interface{}
  • InterfaceName: interface{} -> string
• util
  • generic error handler HandlerErr(err error)

Why Go?

• Gophers
• Hip
• New
• Unproven

Is it good?

Are you good?

Let's Gooo test the example blog app

• resolve dependencies and install
  • ./install
  • don't want to use postgresql?
    • Sign up for a free Heroku Postgres account here.
    • Create a database and save the connection params for the next step.
    • Or skip this step
• configure the database connection variable dbParams in the model package (model/model.go)
• ./Gooo
• http://localhost:8080/hello/world
• Gooo celebrate
• Gooo outside

Let's Gooo write your own Gooo app

• resolve dependencies and install
  • ./install
  • don't want to use postgresql?
    • Sign up for a free Heroku Postgres account here.
    • Create a database and save the connection params for the next step.
• define your model interfaces and configure the database connection in the model package (model/model.go)
  • implement your model interface types with anonymous BaseModel field
    • use `json:"-"` for type safety and Go lang future proofing
  • implement functions and variables available to all models with anonymous BaseModel field in the Model interface type
• define your views as request handler functions in the view package (view/view.go)
• write your templates in tmpl/ (Go text/template syntax)
• define routes in main package gooo.go
• ./Gooo
• http://localhost:8080/hello/world
• Gooo celebrate
• Gooo outside
