使用sonarqube对javascript代码进行扫描，分析代码质量，最简单的方式莫过于使用缺省的sonar-way中的javascript的规则，使用sonar-scanner进行扫描，这篇文章通过最简单的例子，来进行说明。

事前准备

Sonarqube

Sonarqube可以使用docker版本快速搭建，可以参看一下Easypack整理的镜像，具体使用可以参看如下链接，这里不再赘述：

https://hub.docker.com/r/liumiaocn/sonarqube/

环境假定

本文使用到的sonarqube为本机32003可以访问到的服务。版本为5.6.5

sonar-scanner

sonar-scanner详细信息如下：

liumiaocn:sonar liumiao$ sonar-scanner -v
INFO: Scanner configuration file: /Users/liumiao/Desktop/sonar/sonar-scanner-3.2.0.1227-macosx/conf/sonar-scanner.properties
INFO: Project root configuration file: /Users/liumiao/sonar/sonar-project.properties
INFO: SonarQube Scanner 3.2.0.1227
INFO: Java 1.8.0_121 Oracle Corporation (64-bit)
INFO: Mac OS X 10.14 x86_64
liumiaocn:sonar liumiao$ 

项目目录构成

项目文件与目录构成信息如下：

liumiaocn:sonar liumiao$ tree
.
├── sonar-project.properties
└── src
    └── Person.js

1 directory, 2 files
liumiaocn:sonar liumiao$

JavaScript源码

使用如下Person.js的JavaScript源码，详细信息如下

liumiaocn:sonar liumiao$ cat src/Person.js 
var Person = function(first, last, middle) {
    this.first = first;
    this.middle = middle;
    this.last = last;
};

Person.prototype = {

    whoAreYou : function() {
        return this.first + (this.middle ? ' ' + this.middle: '') + ' ' + this.last;
    }

};

var a = NaN;

if (a === NaN) {  // Noncompliant; always false
  console.log("a is not a number");  // this is dead code
}
if (a !== NaN) { // Noncompliant; always true
  console.log("a is not NaN"); // this statement is not necessarily true
}

for (var i = 0; i < strings.length; i--) {
  console.log("dead code")
}

if (str == null && str.length == 0) {
  console.log("String is empty");
}
liumiaocn:sonar liumiao$

sonar-project.properties设定文件

项目设定文件信息详细如下：

liumiaocn:sonar liumiao$ cat sonar-project.properties 
sonar.projectKey=javascript-prj
sonar.projectName=JavaScript Demo Project
sonar.projectVersion=1.0
sonar.sources=src
sonar.host.url=http://127.0.0.1:32003
sonar.login=admin
sonar.password=admin
liumiaocn:sonar liumiao$

执行sonar-scanner

liumiaocn:sonar liumiao$ pwd
/Users/liumiao/sonar
liumiaocn:sonar liumiao$ ls
