Router is a HTTP router for Golang. It's built on httprouter and takes inspiration from labstack/echo, but with reduced complexity and easier data binding.
The data binding is made easier by specifying your input as a parameter to your function
Example:
type someType struct {
A string `json:"a"`
B int `json:"b"`
}
func handlePOST(c *router.Context, input someType) error {
fmt.Println(input)
return c.NoContent(200)
}
Many applications read, bind and validate data for most calls. In Echo this could mean adding boilerplate code to every call. This extra boilerplate code can make your code significantly longer and very hard to read.
func handlePOST(c *echo.Context) error {
var input someType
err := c.Bind(&input)
if err != nil {
return c.NoContent(http.StatusBadRequest)
}
err = c.Validate(input)
if err != nil {
return c.NoContent(http.StatusBadRequest)
}
// Your actual code
}
In router you define your code to read, bind and validate the input once, and it applies to every POST, PATCH and PUT call.
While using dynamic parameters takes a bit of extra processing, this barely has any impact on performance. Router can still handle tens to hunderds of thousands of requests per second.
Middleware works similar to most other routers. The dynamic parameters has no effect on middleware, input data is parsed after all middlewares and right before your handler.
go get git.fuyu.moe/Fuyu/router
package main
import "git.fuyu.moe/Fuyu/router"
func main() {
// Create a router instance
r := router.New()
// Add routes
r.GET(`/`, yourGetFunc)
r.POST(`/`, yourPostFunc)
// Start router
panic(r.Start(`127.0.0.1:8080`))
}
For a serious project you should set r.Reader
, r.ErrorHandler
, r.NotFoundHandler
, and r.MethodNotAllowedHandler
.
You can set r.Renderer
and call c.Render(code, tmplName, data)
in your handlers
package main
import (
"fmt"
"time"
"git.fuyu.moe/Fuyu/router"
)
type product struct {
Name string `json:"name"`
}
func main() {
r := router.New()
r.Use(accessLog)
r.GET(`/hello`, hello)
a := r.Group(`/api`, gandalf)
a.POST(`/product`, createProduct)
a.PATCH(`/product/:id`, updateProduct)
a.POST(`/logout`, logout)
r.Start(`:8080`)
}
func accessLog(next router.Handle) router.Handle {
return func(c *router.Context) error {
t := time.Now()
err := next(c)
fmt.Println(c.Request.Method, c.Request.URL.Path, c.Request.RemoteAddr, t, time.Since(t))
return err
}
}
func gandalf(next router.Handle) router.Handle {
youShallPass := false
return func(c *router.Context) error {
if !youShallPass {
return c.String(401, `You shall not pass`)
}
return next(c)
}
}
func hello(c *router.Context) error {
return c.String(200, `Hello`)
}
func createProduct(c *router.Context, p product) error {
return c.JSON(200, p)
}
func updateProduct(c *router.Context, p product) error {
productID := c.Param(`id`)
return c.String(200, fmt.Sprintf(
`ProductID %d new name %s`, productID, p.Name,
))
}
func logout(c *router.Context) error {
return c.String(200, `logout`)
}
