Function LoadFilesRecursively

endpoints/server/httpserver.go:161–201

LoadFilesRecursively loads HTML and template files recursively from the specified directory and adds them to the given gin.Engine. It walks through the directory and its subdirectories, and for each file with a .html or .tmpl extension, it reads the file content, creates a new template with the file

(g *gin.Engine, dir string)

// The directory path should be a clean absolute path.
// If any error occurs during the file loading or template parsing, the function returns the error.
func LoadFilesRecursively(g *gin.Engine, dir string) {

	if os.IsNotExist(err) {
		// dir does not exist
		return
	}

	rootTmpl := template.New("").Funcs(g.FuncMap)
	f := os.DirFS(cleanRootDir)

	err = fs.WalkDir(f, ".", func(path string, info fs.DirEntry, walkErr error) error {
		// add *.html and *.tmpl files
		if !info.IsDir() && (strings.HasSuffix(path, ".html") || strings.HasSuffix(path, ".tmpl")) {
