File server *and* api on same router

[seal]

Description

I want to be able to have a fileserver providing my JS files & my api on the same router

How to reproduce

package main

import (
    "github.com/gin-gonic/gin"
)
func GetRouterGorm() *gin.Engine {
    r := gin.Default()
    workDir, _ := os.Getwd()
    filesDir := http.Dir(filepath.Join(workDir, "dist"))
    r.GET("/api/ping", func(c *gin.Context) {
        c.String(http.StatusOK, "pong")
    })

    r.StaticFS("/", filesDir)
    return r
}
func main() {
    r := api.GetRouterGorm()
    r.Run(":9000")
}

Expectations

Wanted it to serve the pre-defined routes for api and anything else, js

Actual result

 - using env:   export GIN_MODE=release
 - using code:  gin.SetMode(gin.ReleaseMode)

[GIN-debug] GET    /api/ping                 --> github.com/seal/scansearch/pkg/api.GetRouterGorm.func1 (3 handlers)
[GIN-debug] GET    /*filepath                --> github.com/gin-gonic/gin.(*RouterGroup).createStaticHandler.func1 (3 handlers)
panic: catch-all wildcard '*filepath' in new path '/*filepath' conflicts with existing path segment 'api' in existing prefix '/api'

Hi @seal , You can use r.StaticFS("/static", filesDir) . Beacuse if you use "/", you don't get [api] file in the file system. So you can't use "/" to visit your dist floder.
