This project is part of the Guardjs, that used to extract features of normal javascript source code.
It has the capability to easily reduce or increase a feature model to the feature set through cli or api.

CLI

npx extatistic create --name lengthOfstr.js
To create a new feature named lengthOfstr.js. It can provided as a path.

npx extatistic list
To get the list of all registered features. If any error be in features there should be shown.

npx extatistic list > res.csv

npx extatistic execute
To start executing all features (methods in folder called 'features') on source text (of files in folder called 'input'). Results willl be saved as a csv file in a folder called 'ouput'.

npx extatistic execute >> res.csv

API

There's a sample code to show how to use the code and how it works:

const {
    registerAFeature,       // register a feature in to feature list
    registerFeaturesList,   // register a list of features to feature list
    getListOfFeaturesName,  // return a list of all registered features
    getNumberOfFeatures,    // return total number of registerd features
    extractfeaturesRaw,     // calculate and return a raw of features value
} = require('extatistic')

const newFeature = sourceString => sourceString.length || 0
registerAFeature(newFeature)

console.log(getListOfFeaturesName())                // newFeature
console.log(getNumberOfFeatures())                  // 1
console.log(extractfeaturesRaw('a sample string'))  // 15

const anotherFeature = sourceString => (sourceString.length / 2) || 0
registerAFeature(anotherFeature)

console.log(getListOfFeaturesName())                // newFeature, anotherFeature
console.log(getNumberOfFeatures())                  // 2
console.log(extractfeaturesRaw('a sample string'))  // 15, 7.5

The API:

every feature added should return a primitive value, it's important!
