dom-defect

Detect defections from HTML DOM-Elements

Installation

npm install domdefect

Usage

Initialize the client

const domdefect = require('domdefect');
let detector = new domdefect.Detector();

Set the rules for the detector

// Using pre-defined rule
const {rules} = domdefect;
detector.rules_to_apply = [rules.PREDEFINED[0], rules.PREDEFINED[1]]
// Or customize your rule from Meta rules
let myRule = rules.Meta.checkNumberOfSelected('strong', '<', 2);
let myRule2 = rules.Meta.checkElementAttributes('input', ['value', 'id', 'yo']);
detector.rules_to_apply.push(myRule);
detector.rules_to_apply.push(myRule2);

Load the HTML from source (URL or file path). Then run the detector to get the report.

// Load HTML then run validations
// You can also load HTML from file by passing file path
// like: setDocumentSource('index.html')
detector.setDocumentSource('http://www.example.com')
 .then( () => {
    detector.run();
    
    // Aftter running , the results is stored 
    // in the `report` object in JSON format:
    detector.report.detail()
    
    // You can pretty-print the data
    detector.report.print();
    
    // Output the report into file
    detector.report.toFile('myreport.txt').then(...);
    
    // Or write into a writable stream
    detector.report.writeToStream(stream).then(...);
    
 });

How to cusomize rules for the detector

Using the high order functions inside lib/rules.js.

For exmaple, calling

const {rules} = require('domdefect');
let myRule = rules.Meta.checkNumberOfSelected('strong', '<', 2);

Generates a rule which checks if the number of <strong> tags is less than 2
