 # fis-optimizer-uglify-js
 
-A optimizer for fis to compress js by using uglify-js.
+A optimizer for fis to compress js by using uglify-js.
+
+## 使用
+
+FIS内置
+
+## 配置
+
+在项目配置文件（默认fis-conf.js）配置
+
+```javascript
+fis.config.set('settings.optimizer.uglify-js', option);
+```
+
+eg:
+
+```javascript
+//export, module, require不压缩变量名
+fis.config.set('settings.optimizer.uglify-js', {
+    mangle: {
+        except: 'exports, module, require, define'
+    }
+});
+
+//自动去除console.log等调试信息
+fis.config.set('settings.optimizer.uglify-js', {
+    compress : {
+        drop_console: true
+    }
+});
+```
+
+`option` 详细请参见 https://github.com/mishoo/UglifyJS2

Fixed alerts

New author

Supply chain risk

A new npm collaborator published a version of the package for the first time. New collaborators are usually benign additions to a project, but do indicate a change to the security surface area of a package.

Trivial Package

Supply chain risk

Packages less than 10 lines of code are easily copied into your own project and may not warrant the additional supply chain risk of an external dependency.
