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 🙏

Readme

libudx

udx is reliable, multiplex, and congestion controlled streams over udp.

It's written in C99 and depends on libuv.

It is pre-alpha wip (there be dragons), but at a stage where it's safe for developers to poke at.

The main purpose is to be a building block for P2P networking. It therefore doesn't come with any handshaking protocol, encryption, and things like that - just reliable, fast, streams.

API

TODO

Node.js bindings

npm install udx-native

Building

Two build setups are available: A GYP build and a CMake build.

GYP

The GYP build is used for building a dynamic library for use in Node.js.

node-gyp configure
node-gyp build

The above commands are run as part of npm install.

CMake

The CMake build is used for building static and dynamic libraries for use outside of Node.js.

cmake -S . -B build
cmake --build build

Debugging

When debugging native code, make sure to configure a debug build:

# GYP
node-gyp configure --debug

# CMake
cmake -S . -B build -D CMAKE_BUILD_TYPE=Debug

Memory errors

To diagnose and debug memory errors, such as leaks and use-after-free, the collection of sanitizers provided by LLVM are recommended. The sanitizers can be enabled by passing additional CFLAGS and/or LDFLAGS to the CMake or GYP build:

# GYP
CFLAGS=<...> LDFLAGS=<...> node-gyp build

# CMake
CFLAGS=<...> LDFLAGS=<...> cmake -S . -B build

To read more about the various sanitizers and how to use them, see:

:warning: LeakSanitizer is still experimental and currently requires a newer version of LLVM on macOS. If using Homebrew, brew install llvm and CC=/usr/local/opt/llvm/bin/clang should be sufficient.
