To improve the quality of my JavaScript code, I’m always looking at good tools (like JsLint) that can help me writer better code and more maintainable code.
Last week I discovered Plato,a JavaScript source code visualization, static analysis, and complexity tool.
This node.js module analyses your JavaScript code and gives you an indication about:
- The maintainability of your code
- Lines of code
- Estimated errors in implementation(based on the Halstead complexity measures)
- Lint errors(based on the results of JsHint)
Get started
- Download and install node.js from the node.js website(http://nodejs.org/download/)
- Start a command prompt
- Install plato as a global module through the npm package manager:
npm install -g plato
Browse to the folder where you want to run Plato.Call Plato and specify to do a recursive scan on the scripts folder:plato -r -d reports scriptsGo to the reports folder and open the index.html page to see the results(here you see an example run on Marionette.js):
