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 🙏

Prettier Plugin Sorted List

This is a plugin for Prettier that sorts lists of string literals in your JavaScript or TypeScript code. This tool is designed to make your code cleaner and more readable.

Installation

Firstly, you'll need to install Prettier:

npm install --save-dev prettier

Then, install prettier-plugin-sorted-list:

npm install --save-dev prettier-plugin-sorted-list

Add a Prettier Configuration File

Create a file named .prettierrc in the root of your project and add the following:

{
  "plugins": ["prettier-plugin-sorted-list"]
}

Usage

In your source code, use a comment directive to indicate the list that needs to be sorted:

let arr = [
  // prettier-sorted-list
  "b",
  "a",
];

Then, when Prettier is run, it will sort the list:

let arr = [
  // prettier-sorted-list
  "a",
  "b",
];

Comment Directives

You can use two types of comment directives, line comments and block comments. You can also add comments after the directive to provide a description of the list.

// prettier-sorted-list

// prettier-sorted-list List of items to be sorted

/* prettier-sorted-list */

Limitations and Future Work

This plugin currently only supports sorting of lists of string literals. Lists containing other types of elements are not supported at this time.

To-do list

  • [ ] Support for sorting lists of numbers
  • [ ] Support for sorting object keys
  • [ ] Support for sorting keys of Map and Set objects

Development and Testing

Implementation Details

To keep this plugin fast, it does not construct an abstract syntax tree (AST) of the entire file. Instead, it uses a regular expression to find the comment directive and then sorts the list using a simple string manipulation algorithm. For future work, it may be necessary to use an AST to support more complex sorting operations.

Testing

A test suite is included with this plugin to ensure proper functioning. To run the tests, execute the following command:

npm run test
