    "html_assets_1":{
        "type":"html_assets",
        "routes":[
            {
                "is_global":true,
                "route":"/",
                "directory":"/.../devapt-app-devtools/dist/assets",
                "default":"index.html"
            },

            {
                "route":"/css/.*.css",
