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 🙏

@live-change/codemirror-frontend

SSR Vue app for CodeMirror 6 with a collaborative editing demo wired to @live-change/codemirror-service.

What is implemented

  • Demo route (/): CodeEditor.vue — form fields for targetType, target, document type, CM language, sync status, version; embeds Editor.vue.
  • Collaborative editor (Editor.vue): CodeMirror collab, sendableUpdates / receiveUpdates, getSyncedVersion; loads document via RemoteAuthority; pushes edits to codemirror.edit; applies remote updates from the steps stream.
  • Transport (front/src/codemirror/RemoteAuthority.js): api.get(['codemirror','document', …]), createDocumentIfNotExists, inboxReader on ['codemirror','steps', …], codemirror.edit for outgoing updates; resync hooks on reconnect.
  • Public exports (index.js): CodeEditor, Editor, RemoteAuthority, locales.

Run locally

From this package directory (use project Node version, e.g. via fnm):

  • Dev: yarn dev or yarn ssrDev (see package.json scripts).
  • Build: yarn build (client + SSR + server bundle steps as defined in scripts).
  • E2E (Playwright + @live-change/e2e-test): yarn e2e; timing report: yarn e2e:time; headed browser: yarn e2e:headed or SHOW_BROWSER=1 yarn e2e; single file: yarn e2e:file e2e/codemirror.test.ts.

Copy .env.example to .env if the stack expects env vars for API/SSR (see repo conventions).

Configuration

Server-side service wiring lives in server/services.config.js. The codemirror service entry must declare documentTypes keys that match the document type you pass from the UI (e.g. markdown, code).

Embedding in another app

Import named exports from @live-change/codemirror-frontend or reuse Editor / RemoteAuthority with your own layout and access control.
