Quick overview:

package main

import "net/http"
import "github.com/alash3al/olive-go"

func main() {
	olive.New().GET("/", func(ctx *olive.Context) bool {
		ctx.SetBody("index")
		// return false = "don't run the next matched route with the same method and pattern if any"
		// this feature allows you to run multiple routes with the same properties
		return false
	}).ANY("/page/?(.*?)", func(ctx *olive.Context) bool {
		var body []byte
		ctx.LimitBody(20)
		err := ctx.GetBody(&body)
		ctx.SetBody("this is your input \n")
		ctx.SetBody(body)
		_ = err
		return true
	}).GET("/page", func(ctx *olive.Context) bool {
		ctx.SetBody([]byte("hi !"))
		return false
	}).POST("/page/([^/]+)/and/([^/]+)", func(ctx *olive.Context) bool {
		var input map[string]string
		ctx.GetBody(&input, 512) // parse the request body into {input} and returns error if any
		ctx.SetBody(ctx.Params)
		return false
	}).GroupBy("path", "/api/v1", func(ApiV1 *olive.App){
		ApiV1.GET("/ok", func(ctx *olive.Context) bool {
			ctx.Res.Write([]byte("api/v1/ok"))
			return false
		}).GET("/page/([^/]+)/and/([^/]+)", func(ctx *olive.Context) bool {
			// Params[0] -> current-hostname
			// from parent[1] -> the path regex values
			ctx.Res.Write([]byte("api/v1/ " + ctx.Params[1] + " " + ctx.Params[2]))

Changes

Version 3.0

• Context.GetQuery now accepts new param called body and its type is bool, so you can get the request body as url-decoded as url.Values
• Context.GetBody now accepts one paramater, and you don't need to make([]byte, ...) just pass a &v where v is []byte
• added Context.LimitBody to limit the request body to prevent any memory-leaks attacks while reading it using Context.GetBody .

Version 2.0

• removed panics handler
• removed Context.AddHeaders() and Context.SetHeaders()
• added Context.DelHeader()
• renamed Context.Query() to Context.GetQuery()
• renamed Context.Body() to Context.GetBody()
• renamed Context.Send() to Context.SetBody()
• added support for html templates in Context.SetBody()
• renamed App.Group() to App.GroupBy
• add support for custom vhost routing
