sonarqube-setup: A JavaScript repository from ashishsarkar

Pre-requisite(s)

Added new line

The only prerequisite for running SonarQube is to have Java (Oracle JRE 8 or OpenJDK 8) installed on your machine .https://docs.sonarqube.org/display/SONAR/Requirements

Download below software(s):

LTS version of Sonarqube. https://www.sonarqube.org/downloads/
SonarQube-scanner based on your platform. https://docs.sonarqube.org/display/SCAN/Analyzing+with+SonarQube+Scanner

Steps to setup the sonarqube properites configuration

Once SonarQube-scanner is downloaded, add below two properties in sonar-scanner.properties:
```
#----- Default SonarQube server
sonar.host.url=http://localhost:9000

#----- Default source code encoding
sonar.sourceEncoding=UTF-8
```
sonar-scanner.properties can get under location <path_of_sonarqube_scanner/<choose_platform/conf> For e.g. ~/Documents/software/sonar-scanner-3.2.0.1227-macosx/conf
Create a sonar-project.properties file in root location of your nodejs app.

Add below configuration properties in above created file:

# required metdata
sonar.projectKey=<preferrable_node_app_name>
sonar.projectVersion=<version>
sonar.sourceEncoding=<source code encoding>

# path to srouce directories
sonar.sources=<your_node_app_folder_name>

# excludes
sonar.exclusions=<files or folder which you want to exclude>

# coverage reporting
sonar.javascript.lcov.reportPaths=<code coverage location>

Note: These are required for sonar-scanner to analyaze and generate the report accordingly.

Start the sonarqube server

Go to SonarQube's downloaded location, and run below command:
```
~<path>/sonarqube-6.7.5/bin/macosx-universal-64 $ ./snoar.sh --help
```
`For e.g.: ~/Documents/software/sonarqube-6.7.5/bin/macosx-universal-64 $ ./sonar.sh --start`

Run the sonar-scanner

Got to root directory of your project folder where you have created the `sonar-projects.properties` file and run the below command:
```
~<root path of your project> $ sonar-scanner
```
`For e.g. ~/Documents/learning/sonarqube $ sonar-scanner`

Access the generated report to analyaze further

Get the host url which you have set in the configuration and try accessing it.
Default username and password is: admin/admin For e.g. http://localhost:9000/dashboard?id=<project_key>
