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-TestScheduler-Compat

rxjs-testscheduler-compat provides RxJS v4's test scheduler interface to v5 version of RxJS allows to migrate existing test cases with minimum effort as well as writing new test cases for certain cases.

Install

This has a peer dependencies of rxjs@5.*.*, which will have to be installed as well

npm install @kwonoj/rxjs-testscheduler-compat

Usage

You can import TestScheduler and other helpers to create test cases.

import * as Rx from 'rxjs';
import { TestScheduler, next, complete } from '@kwonoj/rxjs-testscheduler-compat';

const scheduler = new TestScheduler();
const observer = scheduler.createObserver();

const subject = scheduler.createHotObservable(
      next(20, 'a'),
      next(40, 'b'),
      next(60, 'c'),
      complete(80)
    );

subject.subscribe(observer);

scheduler.advanceTo(30);

As this does not patches anything in RxJS v5's test scheduler, you can use both if it's needed

import * as Rx from 'rxjs';
import { TestScheduler as CompatScheduler } from '@kwonoj/rxjs-testscheduler-compat';

const v5Scheduler = new Rx.TestScheduler(...);
const v4Scheduler = new CompatScheduler();

...

Migrating from RxJS v4 test scheduler

There are few changes in api surfaces to conform with v5's scheduler interface as well as enhance conviniences.

ReactiveTest helper functions

  • ReactiveTest.onNext(value) -> next(value)
  • ReactiveTest.onError(value) -> error(value)
  • ReactiveTest.onCompleted(value) -> complete(value)
  • ReactiveTest.subscribe(value) -> subscribe(value)

Notification factory method (next, error, complete) returns implementaiton of TestMessage and subscribe returns SubscriptionLog

Scheduler instance functions

  • TestScheduler::start() -> TestScheduler::flush()
  • does not support scheduler's instance methods for scheduling such as scheduleFuture, schedulerRecursive, schedulePeriodic... except scheduleAbsolute, scheduleRelative, startScheduler

Building / Testing

Few npm scripts are supported for build / test code.

  • build: Transpiles code to ES5 commonjs to dist.
  • build:clean: Clean up existing build
  • test: Run unit test. Does not require build before execute test.
  • test:cover: Run code coverage against test cases
  • lint: Run lint over all codebases
  • lint:staged: Run lint only for staged changes. This'll be executed automatically with precommit hook.
  • commit: Commit wizard to write commit message
