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.

Type-Safe Dependency Injection Container

A lightweight, fully type-safe Dependency Injection (DI) container for TypeScript. Designed for reliability, developer experience, and minification safety.

Table of Contents

Overview

This project provides a DI container that leverages TypeScript's type system to ensure that your dependencies are always resolved correctly. It focuses on a "Pure DI" approach, where dependencies are ideally resolved at the composition root.

Key Features

Strict Type Safety: Full Intellisense and compile-time validation for all registered services.
Multiple Lifetimes: Support for Singleton (global) and Scoped (per-context) services.
Async Support: Seamless integration with asynchronous factories and functions, including async disposal.
Circular Dependency Detection: Detects circular dependencies during resolution.
Minification Proof: Built-in stable identity system ensures that resolution by Class reference works even when class names are mangled.
Zero Runtime Dependencies: A lean implementation with no external dependencies.

Development

Build: npm run bundle
Test: npm test
Smoke Tests: npm start (Runs end-to-end scenarios against bundled code)
