ts-plato

ts-plato

Visualize JavaScript/TypeScript source complexity with plato. Based on es6-plato.

#The Report

Start in 3 steps.

• Install. npm install --save-dev ts-plato

• Add.

"scripts" : {
    "complex": "./node_modules/.bin/ts-plato -r -d ./report src",
}

• Run. npm run complex

Installation

Install the module with: npm install --save-dev ts-plato

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}`;
}

//usage is plato.inspect
plato.inspect(src, outputDir, platoArgs, callback);

Example Gulpfile

let gulp = require("gulp");
let plato = require("ts-plato");

let src = "./scripts/**/*.js";
let outputDir = "./artifacts/plato";

let lintRules = {
  rules: {
    indent: [2, "tab"],
    quotes: [2, "single"],
    semi: [2, "always"],
    "no-console": [1],
    curly: ["error"],
    "no-dupe-keys": 2,
    "func-names": [1, "always"]
  },
  env: {
    ts: true
  },
  globals: ["require"],
  parserOptions: {
    sourceType: "module",
    ecmaFeatures: {
      jsx: true,
      modules: true
    }
  }
};

let complexityRules = {};

let platoArgs = {
  title: "example",
  eslint: lintRules,
  complexity: complexityRules
};

function analysis() {
  return plato.inspect(src, outputDir, platoArgs);
}

gulp.task("analysis", analysis);

Example

ts-plato -r -d report src

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 ts-plato. For instance, if you want to use /src/**/*.js and the results are ignoring the root try './src/**/*.js' instead.
