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.

prodara lsp language-server

@prodara/lsp

Language Server Protocol implementation for Prodara .prd specification files. Provides real-time diagnostics, keyword completion, and document symbols.

Installation

npm install @prodara/lsp

Capabilities

Diagnostics — Real-time bracket/brace matching with debounced validation (300ms)
Completions — All PRD keywords and type names with trigger characters . and :
Document Symbols — Outline view of product, module, entity, workflow, and other block declarations

Architecture

The server is split into two layers:

analysis.ts — Pure functions (validateText, extractSymbols, declKindToSymbolKind) with no connection dependency. Fully testable.
server.ts — LSP connection wiring, document management, and debounced diagnostics.

Module Cache

An LRU cache (ModuleCache) stores parsed module results keyed by document URI. Configurable max size (default: 200 entries). Least-recently-used entries are evicted when the cache exceeds capacity.

Usage with VS Code

The prodara-vscode extension starts this server automatically. See packages/vscode/ for the extension.

Testing

npm test              # 38 tests
npm run test:coverage # Enforces 100% coverage
