+**SPA Page**  
+In spa (single page application) single page application, the page will be refreshed only once. The traditional method only reports PV once after the page loading, but cannot count the PV of each sub-page, and can't make other types of logs aggregate by sub-page.  
+The SDK provides two processing methods for spa pages:  
+1. Enable spa automatic parsing  
+This method is suitable for most single page application scenarios with URL hash as the route.  
+In the initialized configuration item, set enableSPA to true, which will turn on the page's hashchange event listening (trigger re reporting PV), and use URL hash as the page field in other data reporting.  
+2. Manual reporting  
+This method can be used in all single page application scenarios. This method can be used if the first method is invalid.    
+The SDK provides a setpage method to manually update the page name when data is reported. When this method is called, the page PV will be re reported by default. For details, see setPerformance().  
+```

+
+[Apache SkyWalking](https://github.com/apache/skywalking) 客户端JavaScript异常和跟踪库。
+- 使浏览器成为整个分布式跟踪的起点
+- 向SkyWalking后端提供度量和错误收集
+- 轻量级
+
+# 使用
+* 安装  
+skywalking-client-js运行库在npm上提供  
+```
+npm install skywalking-client-js --save
+```
+* 初始化
+SDK以ClientMonitor.register方式初始化
+```
+import ClientMonitor from 'skywalking-client-js';
+```
+```
+ClientMonitor.register({
+  service: 'test-ui',
+  pagePath: 'http://localhost:8080/',
+  serviceVersion: 'v1.0.0',
+});
+```
+* SDK参考
+
+|参数|类型|描述|是否必选|默认值|
+|----|----|----|----|----|
+|service|String|项目id|true|-|
+|serviceVersion|String|项目verison|true|-|
+|pagePath|String|项目路径|true|-|
+|jsErrors|Boolean|支持监控js错误|false|true|
+|apiErrors|Boolean|支持监控API错误|false|true|
+|resourceErrors|Boolean|支持监控资源错误|false|true|
+|useFmp|Boolean|收集首屏时间|false|false|
+|enableSPA|Boolean|监听页面的hashchange事件并重新上报PV，适用于单页面应用场景|false|false|
+|autoTracePerf|Boolean|支持自动上报性能数据|false|true|
+|vue|Boolean|支持监控vue错误|false|true|
+
+* API参考
+
+**register()**  
+在SDK最初完成后，它调用register()接口来修改一些配置项。有关SDK配置项的详细信息，请参阅SDK参考。  
+
+register()语法  
+```
+ClientMonitor.register(params);
+```
+
+register()调用参数  
+|参数|类型|描述|是否必选|默认值|
+|----|----|---------|----|----|
+|params|Object|配置项和值需要改变的|true|-|
+
+**setPerformance()**  
+页面加载后，调用setPerformance()接口来报告默认的性能指标。  
+
+如何使用setPerformance()  
+1. 将SDK配置项autoTracePerf设置为false，从而关闭自动上报性能指标，并等待手动触发上报。  
+2. 调用ClientMonitor.setPerformance(object)方法上报默认性能指标.  
+
+setPerformance()使用案列 
+```
+import ClientMonitor from 'skywalking-client-js';
+
+ClientMonitor.setPerformance({
+  reportUrl: 'http://example.com',
+  service: 'skywalking-ui',
+  serviceVersion: 'v8.1.0',
+  pagePath: location.href,
+  useFmp: true
+});
+```
+* 特殊场景
+
+**SPA页面**  
+在spa（单页应用程序）单页应用程序中，页面将只刷新一次。传统的方法在页面加载后只报告一次PV，不能统计每个子页面的PV，也不能使其他类型的日志按子页面聚合。   
+The SDK provides two processing methods for spa pages:  
+1. 开启SPA自动解析  
+此方法适用于大部分以URL Hash作为路由的单页面应用场景.  
+在初始化的配置项中，设置enableSPA为true，即会开启页面的Hashchange事件监听（触发重新上报PV），并将URL Hash作为其他数据上报中的page字段。   
+2. 手动上报  
+此方法可用于所有的单页面应用场景。如果第一种方法无效，则可用此方法。  
+SDK提供了setPerformanc方法来手动更新数据上报时的参数。调用此方法时，默认会重新上报页面PV，详情请参见setPerformance().  
+```
+app.on('routeChange', function (next) {
+  ClientMonitor.setPerformance({
+    reportUrl: 'http://example.com',
+    service: 'skywalking-ui',
+    serviceVersion: 'v8.1.0',
+    pagePath: location.href,
+    useFmp: true
+  });
+});   
+```
