+import freeflowuniverse.herolib.core.texttools
+
+__global (
+	siteconfigs  map[string]&SiteConfig
+)
+
+@[params]
+pub struct FactoryArgs {
+pub mut:
+	name string = "default"
+}
+
+pub fn new(args FactoryArgs) !&SiteConfig {
+	name := texttools.name_fix(args.name)
+	siteconfigs[name] = &SiteConfig{
+		name: name
+	}
+	return get(name:name)!
+}
+
+pub fn get(args FactoryArgs) !&SiteConfig {
+	name := texttools.name_fix(args.name)
+	mut sc := siteconfigs[name] or {
+		return error('siteconfig with name "${name}" does not exist')
+	}
+	return sc
+}
+
+pub fn default() !&SiteConfig {
+	if siteconfigs.len == 0 {
+		return new(name:'default')!
+	}
+	return get()!
