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 🙏

An NPM for parsing text markup

Readme

@environment-safe/tag-parser

A buildless ESM module for parsing text markup. Successor to tag-parser and, before it, midas.

TagParser

First include the module:

import { TagParser } from '@environment-safe/tag-parser';

then, instantiate the object:

const parser = new TagParser([environments]);

where environments may contain:

  1. name :
  2. sentinels : a list of the following mixed types:
    1. an array of 2 strings, the first being the 'open' sentinel, the second, 'close'.
    2. an object containing 'opener' && 'closer'
    3. a single string that is both the opener and closer
  3. onParse : a callback allowing you to make custom modifications of an existing tag

parse with:

const parseTree = parser.parse(text);

SAXParser

A traditional, event based Simple API for XML parser which supports both emitter subscription and passed function configurations.

import { SAXParser } from '@environment-safe/tag-parser';

const parser = new SAXParser({
    onTagOpen: (tag)=>{
        //react to tag open
    },
    onTagClose: (tag)=>{
        //react to tag open
    },
    onComment: (tag)=>{
        //react to comment
    },
    onEscape: (tag)=>{
        //react to escape
    },
    onText: (text)=>{
        //react to text
    },
});
parser.parse(xml);

HTMLParser

In order to parse HTML:

import { HTMLParser } from '@environment-safe/tag-parser/html'
const parser = new HTMLParser();
const parseTree = parser.parse('<html><head><title>Awesome!</title></head><body onload="callReady()"><h1>Congrats</h1><p>It worked.</p><!--a comment--></body></html>');

which will produce:

{
    type: 'tag',
    text: 'html',
    name: 'html',
    attributes: {},
    children: [
        {
            type: 'tag',
            text: 'head',
            name: 'head',
            attributes: {},
            children: [
                {
                    type: 'tag',
                    text: 'title',
                    name: 'title',
                    attributes: {},
                    children: [
                        'Awesome!'
                    ]
                }
            ]
        },
        {
            type: 'tag',
            text: 'body onload="callReady()"',
            name: 'body',
            attributes: {
                onload : 'callReady()'
            },
            children: [
                {
                    type: 'tag',
                    text: 'h1',
                    name: 'h1',
                    attributes: {},
                    children: [
                        'Congrats!'
                    ]
                },
                {
                    type: 'tag',
                    text: 'p',
                    name: 'p',
                    attributes: {},
                    children: [
                        'It worked.'
                    ]
                },
                {
                    type: 'comment',
                    text: 'a comment',
                    children: [
                        'a comment'
                    ]
                }
            ]
        }
    ]
}

Template + TemplateParser

Parse and render simple value based ES6 template statements, but dynamically at runtime.

import { Template } from '@environment-safe/tag-parser/template';
const template = new Template(
    'I had a ${foo} but made a ${bar}, now I have some ${baz}'
);
const rendered = template.render({
    foo: 'mogwai',
    bar: 'cake',
    baz: 'gremlins'
});

UBB + UBBParser

Parse and render UBB Codes statements, but dynamically at runtime.

import { UBB } from '@environment-safe/tag-parser/ubb';
const template = new UBB(`+1!
email me at: [email][email protected][/email]
[quote]Oh, you can’t help that. We're all mad here.[/quote]`);
const rendered = template.render();

Mustache + MustacheParser

Parse and render Mustache templates, but dynamically at runtime.

import { Mustache } from '@environment-safe/tag-parser/mustache';
const template = new Mustache('{{#repo}}<b>{{name}}</b>{{/repo}}');
const rendered = template.render({
    "repo": [
        { "name": "resque" },
        { "name": "hub" },
        { "name": "rip" }
    ]
});

Testing

Run the es module tests to test the root modules

npm run import-test

to run the same test inside the browser:

npm run browser-test

to run the same test headless in chrome:

npm run headless-browser-test

to run the same test inside docker:

npm run container-test

Run the commonjs tests against the /dist commonjs source (generated with the build-commonjs target).

npm run require-test

Development

All work is done in the .mjs files and will be transpiled on commit to commonjs and tested.

If the above tests pass, then attempt a commit which will generate .d.ts files alongside the src files and commonjs classes in dist
