How it works?

routegen will scan your go project folders and generate routes when detects special function name (GET, POST, etc) in your package. It will use the relative file path as the route path, you may also modify the route name by alias and use wildcard or named parameter. The method of code injection refers to wire.

Here we will use Gin as a test example. Create the folder strcuture as below

📁
|-📁foo
| |-handle.go
| |-📁bar
| | |-handle.go
|-main.go
|-go.mod

Create ./main.go

//go:build routegeninject

package main

import (
	"github.com/gin-gonic/gin"
	"github.com/serkodev/routegen"
)

func Build(g *gin.Engine) {
    // important! placeholder for routes output
	routegen.Build(g)
}

func main() {
	g := gin.Default()
	Build(g)
	g.Run()
}

Create ./foo/handle.go

package foo

import "github.com/gin-gonic/gin"

func GET(c *gin.Context) {}

Create ./foo/bar/handle.go

package bar

import "github.com/gin-gonic/gin"

func GET(c *gin.Context) {}

Run generate command at your project root
