Automated Code Review - JavaScript

Today, I will provide example of performing a quick and easy way to conduct automated code review on your javascript source.

Pre-requisite

Nodejs and NPM

Install Plato (One time setup)

Plato is a “JavaScript source code visualization, static analysis and complexity tool”

Run the following command in your

• Command Prompt (Windows)
  • npm install -g plato
• Terminal (Mac)
  • sudo npm install -g plato
  • You would be asked to type your system’s password

Analyze the code

• Open Terminal (Or Command Prompt in Windows)
• CD to the project root directory (or to www where your javascript files are stored)
• Run following command
  • plato -r -d reports ./
• Access the reports in directory named “reports"

Pro tips

If you run the plato check often during development, the report will show the changes (positive / negative) in the number of issues being reported. And the underlying jshint review tool is completely configurable to include / exclude various checks. Read manual in the links supplied.
