Compilation checks only this displayed example. It does not verify runtime behavior, all package features or vulnerability reachability.

package main

import (
    "fmt"
    "net/http"
    "net/http/httptest"
    "github.com/go-chi/chi/v5"
)

func main() {
    router := chi.NewRouter()
    router.Get("/hello/{name}", func(w http.ResponseWriter, r *http.Request) {
        fmt.Fprintln(w, "hello", chi.URLParam(r, "name"))
    })
    response := httptest.NewRecorder()
    router.ServeHTTP(response, httptest.NewRequest(http.MethodGet, "/hello/Go", nil))
    fmt.Print(response.Body.String())
}

Compile verification covers this example only. It does not test runtime behavior or every optional feature.

Reproduce the compilation with pinned dependencies

Save the example as main.go alongside these files in a new directory. Use the recorded Go toolchain and CGO_ENABLED=0 to compile for a recorded target.
