🚀 Installation
The only requirement is the Go Programming Language, at least version 1.8.x
$ go get github.com/get-ion/ion
ion takes advantage of the vendor directory feature. You get truly reproducible builds, as this method guards against upstream renames and deletes.
// file: main.go
package main
import (
"github.com/get-ion/ion"
"github.com/get-ion/ion/context"
)
func main() {
app := ion.New()
// Load all templates from the "./templates" folder
// where extension is ".html" and parse them
// using the standard `html/template` package.
app.RegisterView(ion.HTML("./templates", ".html"))
// Method: GET
// Resource: http://localhost:8080
app.Get("/", func(ctx context.Context) {
// Bind: {{.message}} with "Hello world!"
ctx.ViewData("message", "Hello world!")
// Render template file: ./templates/hello.html
ctx.View("hello.html")
})
// Start the server using a network address and block.
app.Run(ion.Addr(":8080"))
}
<!-- file: ./templates/hello.html -->
<html>
<head>
<title>Hello Page</title>
</head>
<body>
<h1>{{.message}}</h1>
</body>
</html>
$ go run main.go
> Now listening on: http://localhost:8080
> Application started. Press CTRL+C to shut down.
Hello World with Go 1.9
If you've installed Go 1.9 then you can omit the github.com/get-ion/ion/context package from the imports statement.
// +build go1.9
package main
import "github.com/get-ion/ion"
func main() {
app := ion.New()
app.RegisterView(ion.HTML("./templates", ".html"))
app.Get("/", func(ctx ion.Context) {
ctx.ViewData("message", "Hello world!")
ctx.View("hello.html")
})
app.Run(ion.Addr(":8080"))
}
We expect Go version 1.9 to be released in August, however you can install Go 1.9 beta today.
Installing Go 1.9beta2
- Go to https://golang.org/dl/#go1.9beta2
- Download a compatible, with your OS, archieve, i.e
go1.9beta2.windows-amd64.zip - Unzip the contents of
go1.9beta2.windows-amd64.zip/gofolder to your $GOROOT, i.eC:\Go - Open a terminal and execute
go version, it should output the go1.9beta2 version, i.e:
C:\Users\hiveminded>go version
go version go1.9beta2 windows/amd64
Why another new web framework?
ion is easy, it has a familiar API while in the same has far more features than Gin or Martini.
You own your code —it will never generate (unfamiliar) code for you, like Beego, Revel and Buffalo do.
It's not just-another-router but its overall performance is equivalent with something like httprouter.
Unlike fasthttp, ion provides full HTTP/2 support for free.
Compared to the rest open source projects, this one is very active and you get answers almost immediately.
