ScanningHTMLFile

Developing a Node.js package to let a user use this package to scan a HTML file and show all of the SEO defects.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Installation

Install Scanning HTML file SEO defects globally using npm: npm install --save scanning-html-file

Example

To get familiar with usage of the module: node index.js

Output should be printed to terminal like below:

Show all of the SEO defects Finish all SEO defects scan All in this HTML file contain attribute "alt". This HTML file contains 30 tag without rel attribute. This HTML file does not have a <meta name="description" .../> tag This HTML file does not have a <meta name="keywords" .../> tag This HTML has less than 15, tag. Count = 0 This HTML has less than 1, tag. Count = 0

Usage

The input can be either: I. A HTML file (User is able to config the input path) II. Node Readable Stream

The output can be either: I. A file (User is able to config the output destination) II. Node Writable Stream III. Console

Basic usage

1. Input file: /**

• Setup The input is A HTML file from the path
• @param {object} input - used to feed in HTML file source */ scanningHTMLFile.setInput(new Input().createInputFile(__dirname+"/test/Node.js.html"));

/**

• Setup the output is console
• @param {object} output - console */ scanningHTMLFile.setOutput(new Output().createOutputConsole());

2. Input readable stream: /**

• Setup the input is A Node Readable Stream
• @param {object} input - used to feed in HTML file source */ var readable_stream = fs.createReadStream(__dirname+"/test/Node.js.html"); scanningHTMLFile.setInput(new Input().createInputStream(readable_stream));

3. Output to console: /**

• Setup the output is console
• @param {object} output - console */ scanningHTMLFile.setOutput(new Output().createOutputConsole());

4. Output to a file: /**

• Setup the output is a file
• @param {object} output - used to feed in HTML file source */ scanningHTMLFile.setOutput(new Output().createOutputFile(__dirname+"/output.txt"));

5. Output to readable stream: /**

• Setup the output is A Node Readable Stream
• @param {object} output - used to feed in HTML file source */ var writeable_stream = fs.createWriteStream(__dirname + '/outstream.txt') scanningHTMLFile.setOutput(new Output().createOutputStream(writeable_stream));

6. Pre-defined SEO rules: var rules = { img: 'alt', // if there are any tags without alt attribute a: 'rel', // if there are any tags without rel attribute head: { title: true, // if there is any header that doesn’t have tag meta: ["description", "robots", "keywords"], // If you want to implement additional rule for meta tag, you just need to add a new tag to array. }, strong: 15, // there are more than 15 tag in HTML h1: 1, // if a HTML have more than one tag };
