ponticus
Visualize JavaScript source complexity with plato.
Based on the older es5 plato, this is a port to es6
and eslint
Start in 3 steps.
-
Install.
npm install --save-dev @ponticus/ponticus
-
Add.
"scripts" : {
"complexity-report": "./node_modules/.bin/ponticus -r -d ./report src",
}
- Run.
npm run complexity-report
Installation
Install the module with: npm install --save-dev @ponticus/ponticus
Usage
From scripts
//be sure and set your src, output, and any options.
let src = "./scripts/**/*.js";
let outputDir = "./artifacts/plato";
let platoArgs = {
title: "example",
eslint: {}
};
//you can use the reports in the callback.
function callback(reports) {
let overview = plato.getOverviewReport(reports);
let { total, average } = overview.summary;
let output = `total
----------------------
eslint: ${total.eslint}
sloc: ${total.sloc}
maintainability: ${total.maintainability}
average
----------------------
eslint: ${average.eslint}
sloc: ${average.sloc}
maintainability: ${average.maintainability}`;
console.log(output);
}
//usage is plato.inspect
plato.inspect(src, outputDir, platoArgs, callback);

Note for Windows Users: If you are on Windows, you might want to put your glob in quotes if you use a tool such as cygwin, conemu or some other emulator, and you are also targeting files in directories, otherwise the emulator might incorrectly expand the glob before it is handled internally by ponticus. For instance, if you want to use
/src/**/*.js
and the results are ignoring the root try'./src/**/*.js'
instead.
