frontend - Sass compiler Phoenix Framework -

i new front-end phoenix framework , trying implement sass, “priv/static/css/app.css” not compiling using “web/static/css/app.scss”. app.css.map file looks this:

{"version":3,"sources":"web/static/css/app.scss","names":[],"mappings":"","file":"priv/static/css/app.css"}

and brunch.config file looks this:

exports.config = {   // see http://brunch.io/#documentation docs.   files: {     scripts: {       jointo: "js/app.js"        // use separate vendor.js bundle, specify 2 files path       // https://github.com/brunch/brunch/blob/stable/docs/config.md#files       // jointo: {       //  "js/app.js": /^(web\/static\/js)/,       //  "js/vendor.js": /^(web\/static\/vendor)|(deps)/       // }       //       // change order of concatenation of files, explicitly mention here       // https://github.com/brunch/brunch/tree/master/docs#concatenation       // order: {       //   before: [       //     "web/static/vendor/js/jquery-2.1.1.js",       //     "web/static/vendor/js/bootstrap.min.js"       //   ]       // }     },     stylesheets: {       jointo: "css/app.css"     },     templates: {       jointo: "js/app.js"     }   },    conventions: {     // option sets should place non-css , non-js assets in.     // default, set "/web/static/assets". files in directory     // copied `paths.public`, "priv/static" default.     assets: /^(web\/static\/assets)/   },    // phoenix paths configuration   paths: {     // dependencies , current project directories watch     watched: [       "web/static",       "test/static"     ],      // compile files     public: "priv/static"   },    // configure plugins   plugins: {     babel: {       // not use es6 compiler in vendor code       ignore: [/web\/static\/vendor/]     }     sass: {       options: {         includepaths: ['web/static/vendor/bootstrap-sass/assets/stylesheets']       }     }   },    modules: {     autorequire: {       "js/app.js": ["web/static/js/app"]     }   },    npm: {     enabled: true,     // whitelist npm deps pulled in front-end assets.     // other deps in package. excluded bundle.     whitelist: ["phoenix", "phoenix_html"]   } };
