Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

seo-tags-validator

A library to validate SEO tags for html payloads.

  • Validates the basic seo friendly rules.
  • Customisable config file to add other rules for validation.

Currently provided rules are -

  • Check for a title tag.
  • Check if every img tag has an alt attribute.
  • Check for meta tag with name attribute and value description.
  • Check for meta tag with name attribute and value keywords.
  • Check if the number of h1 tags exceed count of 1.
  • Check if the number of strong tags exceed count of 15.

Usage

//Function for html payload validation.
const validator = require('seo-tags-validator');
validator(htmlBody,tagstoValidate);

The validator function accepts two arguments:

  1. The html payload to be validated.
  2. The tags to be validated as an array. If empty validates the html payload against all the rules.
//Function for html file validation.
const validatorFs = require('seo-tags-validator');
validatorFs(htmlFilePath,tagsToValidate);

The validatorFs function accepts two arguments:

  1. The html file path to be validated.
  2. The tags to be validated as an array. If empty validates the html payload against all the rules.

Example

const validator = require('seo-tags-validator');
validator(`<html><head><meta name="description" content=""/></head><body><img /></body></html>`);

Output:

WARNING : No <title> tag(s)
WARNING : Line: 1 <img> tag doesn't have attribute: "alt" or is empty
INFO : No <a> tags
INFO : No <h1> tag(s)
INFO : No <strong> tag(s)
WARNING : Line: 1 <meta> tag with attribute: "name" and value "description" doesn't have content attribute
WARNING : <meta> tag with attribute: "name" and value: "keywords" doesn't exist

Advanced

The config file can be appended with other customisable rules. Below is the template for the rules currently supported.

|Rule |Description | |---|---| |{ "tag": "title" } | To check if the tag title exists in the html payload |
|{"tag": "img","attribute": "alt"} | To check if every tag img has the attribute alt |
|{"tag":"h1","count":1} | To check if the tag h1 exceeds the given count | |{"tag": "meta","attribute":{"key":"name","value":"keywords"} } | This rule is specific for meta tags: But can be used for checking if tag meta has attribute name and value keywords |

Replace the tags and attributes with any of your specific requirements.
