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 🙏

Readme

Vite Plugin Remove Blocks test workflow

The vite-plugin-remove-blocks removes marked blocks from any type of code.

Install

# NPM
npm install --save-dev vite-plugin-remove-blocks
# Yarn
yarn add --dev vite-plugin-remove-blocks

Options

ignoreNodeModules an boolean defines whether to process the node_modules folder.

blocks an array of blocks' representations. Each element of this array describes a unique pair of tags with name, prefix, and suffix. These values are represented by a string or an object with the following properties:

name: 'devblock',              # string value defines the name of start/end tags (unique)
prefix: '/*',                  # string value defines the beginning of a tag
suffix: '*/',                  # string value defines the end of a tag

Usage example

Suppose, the task is to remove some debug information and non-production code from this code sample.

function makeFoo(bar, baz) {
    console.log('creating Foo'); 
    
    if (bar instanceof Bar !== true) {
        throw new Error('makeFoo: bar param is required and must be instance of Bar');
    }
    
    if (baz instanceof Baz !== true) {
        throw new Error('makeFoo: baz param is required and must be instance of Baz');
    }
    
    return new Foo(bar, baz);
}

The plugin removes blocks of code marked with two paired tags (a block). A block is represented by a string or an object with a name, prefix and suffix. Let's identify two different blocks and describe them in the configuration:

// vite.config.js 
import {defineConfig} from 'vite';
import RemoveBlocks from 'vite-plugin-remove-blocks';

export default defineConfig({
  plugins: [
    RemoveBlocks({
      blocks: [
        'debug',
        {
          name: 'development',
          prefix: '//',
          suffix: '',
        },
      ],
    }),
  ],
})

Once the blocks are described in the configuration, the unwanted areas of code can be marked in the code:

function makeFoo(bar, baz) {
    /* debug:start */ console.log('creating Foo'); /* debug:end */
    // development:start
    if (bar instanceof Bar !== true) {
        throw new Error('makeFoo: bar param is required and must be instance of Bar');
    }
    // development:end
    // development:start
    if (baz instanceof Baz !== true) {
        throw new Error('makeFoo: baz param is required and must be instance of Baz');
    }
    // development:end
    // This code will remain
    return new Foo(bar, baz);
}

After the building process, the marked blocks will be completely removed.

function makeFoo(bar, baz) {
    // This code will remain
    return new Foo(bar, baz);
}
