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 🙏

RxJS 5 (alpha)

Reactive Extensions Library for JavaScript. This is a rewrite of Reactive-Extensions/RxJS and is intended to supersede it once this is ready. This rewrite is meant to have better performance, better modularity, better debuggable call stacks, while staying mostly backwards compatible, with some breaking changes that reduce the API surface.

Installation and Usage

npm

To install this library via npm version 3, use the following command:

npm install @reactivex/rxjs

If you are using npm version 2 before this library has achieved a stable version, you need to specify the library version explicitly:

npm install @reactivex/[email protected]

CDN

For CDN, you can use npmcdn. Just replace version with the current version on the link below:

https://npmcdn.com/@reactivex/[email protected]/dist/global/Rx.js

Node.js Usage:

var Rx = require('@reactivex/rxjs');

Rx.Observable.of('hello world')
  .subscribe(function(x) { console.log(x); });

Goals

  • Provide better performance than preceding versions of RxJS
  • To model/follow the ES7 Observable Spec to the observable.
  • Provide more modular file structure in a variety of formats
  • Provide more debuggable call stacks than preceding versions of RxJS

Building/Testing

The build and test structure is fairly primitive at the moment. There are various npm scripts that can be run:

  • build_es6: Transpiles the TypeScript files from src/ to dist/es6
  • build_cjs: Transpiles the ES6 files from dist/es6 to dist/cjs
  • build_amd: Transpiles the ES6 files from dist/es6 to dist/amd
  • build_global: Transpiles/Bundles the CommonJS files from dist/cjs to dist/global/Rx.js
  • build_all: Performs all of the above in the proper order.
  • build_test: builds ES6, then CommonJS, then runs the tests with jasmine
  • build_perf: builds ES6, CommonJS, then global, then runs the performance tests with protractor
  • build_docs: generates API documentation from dist/es6 to dist/docs
  • build_cover: runs istanbul code coverage against test cases
  • test: runs tests with jasmine, must have built prior to running.
  • tests2png: generates PNG marble diagrams from test cases.

Example

# build all the things!
npm run build_all

Performance Tests

Run npm run build_perf or npm run perf to run the performance tests with protractor. Run npm run perf_micro to run micro performance test benchmarking operator.

Adding documentation

RxNext uses ESDoc to generate API documentation. Refer to ESDoc's documentation for syntax. Run npm run build_docs to generate.

Generating PNG marble diagrams

The script npm run tests2png requires some native packages installed locally: imagemagick, graphicsmagick, and ghostscript.

For Mac OS X with Homebrew:

  • brew install imagemagick
  • brew install graphicsmagick
  • brew install ghostscript

For Debian Linux:

  • sudo add-apt-repository ppa:dhor/myway
  • apt-get install imagemagick
  • apt-get install graphicsmagick
  • apt-get install ghostscript
