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 🙏

Note This project is in Alpha phase right now. Major changes might occur.

Usage

Just install the plugin to your preferred system, and it should plug into your project.

Features

The current featureset is as follows:

  • Provides Completions for custom elements defined in the local Custom Elements Manifest and ones in node_modules
  • Provides type hints for attributes and properties on html tages
  • Provides Go To Definition -functionality for Custom Elements defined in the Custom Elements Manifest
  • Provides diagnostics on missing imports and unclosed custom element tags

Disabling diagnostics

Sometimes CELS might catch some diagnostics that might not be useful for your usecase.

Adding a comment anywhere in your code with the given code, will disable diagnostics for said file.

These diagnostics can be disbled with the following flags:

| Command | Action | | --------------------------- | ------------------------------------------------------ | | cels-disable-diagnostics | Disable all diagnostics | | cels-disable-missing-closed | Disable diagnostics for non-closed custom element tags | | cels-disable-import-check | Disable checks for non-imported custom elements |

Installing

VS Code

For VS Code, you are able to install the Custom Elements Language Server through the extension Marketplace.

You can find the plugin here


NeoVim

NeoVim supports LSP actions through the built in LSP. You will just need to install the Language Server locally on your machine through npm or yarn, and then enable your connector for the language service.

Install language server

Install the server plugin from NPM

npm install -g custom-elements-languageserver

Set up your lsp client

With a library like nvim-lspconfig the client setup should be as easy as

require'lspconfig'.custom_elements_ls.setup{}

Other editors

Is your favorite editor missing? If the editor supports LSP actions, plugging it in should be easy. If you need assistance, submit an issue.

The Goal

The aim of the Custom Elements Language Server / Language services is to create a centralized server for supporting LSP operations on Custom Elements.

These operations include but are not limited to

  • Go To Definition
  • Attribute autocompletion
  • Slot name autocompletions
  • Event binding completions

Via installing a plugin to your favorite editor to support LSP actions, you are able to enable all of these Language Service functionalities.
