JSJ 269 Reusable React and JavaScript Components with Cory House

On today’s episode of JavaScript Jabber, we have panelists Joe Eames, Aimee Knight, Charles Max Wood, and playing the part of both host and guest, Cory House. Encourage your team to investigate reusable components, whether that’d be React, Angular, Vue, or Ember. Tune in!

[00:01:35] – Overview

We can finally write reusable components that it is really lightweight. It doesn’t take much framework-specific code to get things done.

Around 3 years ago, the idea of web component standard was all front-end developers could share our components with each other whether someone is in Angular or React. Web components continue to be an interesting standard but people continue to reach for JavaScript libraries instead – React, Angular, Vue. 

[00:04:50] – Browser support issue

The story in JavaScript libraries is easier. You have more power, more flexibility, more choices, and get superior performance, in certain cases, by choosing a JavaScript library over the standard right now. If you try to use the web components standard, you have to Polyfill-in some features so you can run things across browser. You also won’t get JavaScript features like intelligently splitting bundles and lazy load different components.

Whether you’re in Angular or React, you have this model of putting your data in your curly braces. That setup is non-existent in standardized web components. You have to play the game of putting and pulling data into and out the DOM using DOM selectors. You actually take a step backward in developer ergonomics when you choose to leverage the platform instead.

[00:07:50] – Polymer

The reason that Polymer is useful is it adds some goodness on top of web components. One of those things is that it makes it easier to bind in data and not having to do things like writing a DOM query to be able to get your hands on this div and put this text inside of it. With Polymer, you can do something that feels more like Angular, where you can put in your curly braces and just bind in some data into that place. Polymer ends up adding some nice syntactic sugar on top of the web components standard just to make it easier to create web components. Polymer is also used to bundle in Polyfill for the features across browser.   

[00:14:20] – Standards are dead

No. The standard itself has been embraced at different levels by different libraries. What you can see for the near future is popular libraries leveraging pieces of the web components platform to do things in a standard-spaced way. Effectively, Angular, Vue, Aurelia, are going to be abstractions over the web components standard. Arguably the most popular way to do components today is React. But React completely ignores the web components standard. When you look at React, you can’t see what piece of the web components standard would fundamentally make React a better component library.

Cory can’t seem to run to anybody that is actually using the standard in production to build real applications. People continue to reach for the popular JavaScript libraries that we so often hear about.

[00:17:05] – Libraries making reusable components

There is a risk that it would have been a waste for people writing components on Angular, for React, for Vue. But it’s not necessarily safer writing on the web component standard when you have so few people leveraging that standard. There’s always the risk that that standard may shift as well.

As an example, Cory’s team created approximately 100 reusable components in React. If they end up moving to a hot new library, the components are really just functions that take parameters and contain HTML. There is little there

[00:21:20] – Why opt for reusable components

Reusable components are inherently useful in a situation where you’re going to be doing something more than once. If you think about any work that you do as a software developer, we’d like to think that we’re coming in and creating new things but often it is groundhogs day. There are all sorts of opportunities for reuse.

As a company, we want to encapsulate our forms in reusable components so it’s literally impossible for our software developers to do something that goes against our standard. That’s the power of reusable components.  

[00:31:20] – Rigid component vs. flexible component

As component developers, if we try to create a reusable component in a vacuum, bad things happen. If you’re going to do a reusable component, start by solving a specific problem on a given application. If we think that a component’s going to be useful in multiple places, we put it in a folder called reusable right there in our application source folder.

We try to follow that rule of three as well. If we’ve taken that component and used it in 3 places, that’s a good sign that we should extract it out, put it in our NPM package, that way, everybody has this centralized component to utilize. At that point, it has been tested. It’s been through the fire. People have used it in the real world in a few places so we can be confident that the API is truly flexible enough.

Be as rigid as you can upfront. Once you add features, it’s really hard to take features away. But it’s quite easy to add features later. If you start with something rigid, it’s easier to understand. It’s easier to maintain and you can always add a few more switches later.

[00:36:00] – Reusable components

The reason that we can’t reuse code is every time a new project comes up, people are spending up their own ideas rather than leveraging standards that should have been put in place previously.

We’ve had the technical ability to do this for a long time. We just haven’t been around long enough for consolidation to happen, for standardization to happen. You look at how quickly things are changing in our industry. For instance, a couple of years ago, everybody had pretty much decided that two-way binding was the way to build web applications. And then, React came along and shook that up. So today, you have different ways of thinking about that issue.

[00:42:45] – Component development on teams

Aimee’s team has component development and they’re using Angular 1.6. All of our base components are sitting in a seed application. We just go in when we want to create a new property and we just extend all of those components with specific functionalities that we need.

[00:47:45] – Mobile to web crossover

Cory’s team is creating React components but it’s not leveraged on a mobile application. But people use React Native components on the web. And in fact, if you use create-react-app today, you can do that right now. It’s wired up to work in React Native components. In that way, you can literally have these same components running on your Native mobile apps as you do on your web application.

[00:50:00] – Challenge

Cory’s challenge for everybody listening is sit down with your team and have a quick conversation about whether you think components make sense. Look back at the last few months of development and say, "if we have a reusable component library, what would be in it? How often have we found ourselves copying and pasting code between different projects? How much benefit would we get out of this story?"

Once you’ve realized the benefits of the component model, both in the way that makes you think about your application, in a way that it helps you move faster and faster over time, I really think you won’t go back to the old model. I’d encourage people to investigate reusable components, whether that’d be React, Angular, Vue or Ember.

Special Guest: Sean Hunter

In this episode, the panel talks with Sean Hunter who is a software developer, speaker, rock climber, and author of “Aurelia in Action” published by Manning Publications! Today, the panelists and Sean talk about Aurelia and other frameworks. Check it out!

Show Topics:

0:00 – Advertisement: KENDO UI

0:38 – Joe: Hello! Our panelists are AJ, Jesse, myself, and our special guest is Sean Hunter (from Australia)! What have you been doing with your life and what is your favorite movie?

1:45 – Guest talks about Vegemite!

2:20 – Guest: I was in the UK and started using Aurelia, which I will talk about today. I have done some talks throughout UK about Aurelia. Also, the past year moved back to Australia had a baby son and it’s been a busy year. Writing a book and being a new parent has been hard.

3:22 – Panel: Tell us the history of Aurelia, please?

3:31 – Panel: Is it like jQuery, React, Vue or what?

3:44 – Guest: Elevator pitch – Aurelia is a single-page app framework! It’s most similar to Vue out of those frameworks; also, similarities to Ember.js.

4:30 – Guest goes into detail about Aurelia.

6:15 – Panel: It sounds like convention over configuration.

6:42 – Guest: Yes that is correct.

7:21 – Panel: Sounds like there is a build-step to it.

7:39 – Guest: There is a build-step you are correct. You will use Webpack in the background.

9:57 – The guest talks about data binding among other things.

10:30 – Guest: You will have your app component and other levels, too.

10:37 – Panel: I am new to Aurelia and so I’m fresh to this. Why Aurelia over the other frameworks? Is there a CLI to help?

11:29 – Guest: Let me start with WHY Aurelia and not the other frameworks. The style that you are using when building the applications is important for your needs. In terms of bundling there is a CUI and that is a way that I prefer to start my projects. Do you want to use CSS or Webpack or...? It’s almost a wizard process! You guys have any questions about the CLI?

14:43 – Panel: Thanks! I was wondering what is actually occurring there?

15:25 – Guest: Good question. Basically it’s that Aurelia has some built-in conventions. Looking at the convention tells Aurelia to pick the Vue model by name. If I need to tell the framework more information then...

17:46 – Panel: I think that for people who are familiar with one or more framework then where on that spectrum would Aurelia fall?

18:20 – Guest: It’s not that opinionated as Ember.js.

19:09 – Panel: Talking about being opinionated – what are some good examples of the choices that you have and how that leads you down a certain path? Any more examples that you can give us? 

19:38 – Guest: The main conventions are what I’ve talked about already. I can’t think of more conventions off the top of my head. There are more examples in my book.

20:02 – Panel: Your book?

20:10 – Guest: Yep.

20:13 – Panel.

20:20 – Guest. 

21:58 – Panel: Why would I NOT pick Aurelia?

22:19 – Guest: If you are from a React world and you like having things contained in a single-file then Aurelia would fight you. If you want a big company backing then Aurelia isn’t for you.

The guest goes into more reasons why or why not one would or wouldn’t want to use Aurelia.

24:24 – Panel: I think the best sell point is the downplay!

24:34 – Guest: Good point. What does the roadmap look like for Aurelia’s team?

25:00 – Guest: Typically, what happens in the Aurelia framework is that data binding (or router) gets pushed by the core team. They are the ones that produce the roadmap and look forward to the framework. The core team is working on the NEXT version of the framework, which is lighter, easier to use, and additional features. It’s proposed to be out for release next year.

27:34 – Panel: I am going to take down the CLI down and see what it does. I am looking at it and seeing how to teach someone to use it. I am using AU, new command, and it says no Aurelia found. I am stuck.

28:06 – Guest: What you would do is specify the project name that you are trying to create and that should create it for you.

28:50 – Panel: Stand up on your desk and say: does anyone know anything about computers?!

29:05 – Panelists go back-and-forth.

29:13 – Panel: What frameworks have you used in the past?

29:17 – Guest: I was using single-paged apps back in 2010.

31:10 – Panel: Tell us about the performance of Aurelia?

31:17 – Guest: I was looking at the benchmarks all the time. Last time I looked the performance was comparable. Performances can me measured in a number of different of ways.

The guest talks about a dashboard screen that 20 charts or something like that. He didn’t notice any delays getting to the client.

33:29 – Panel: I heard you say the word “observables.”

33:39 – Guest answers the question.

35:30 – Guest: I am not a Redux expert, so I really can’t say. It has similar actions like Redux but the differences I really can’t say.

36:11 – Panel: We really want experts in everything! (Laughs.)

36:25 – Panelist talks about a colleagues’ talk at a conference. He says that he things are doing too much with SPAs. They have their place but we are trying to bundle 8-9 different applications but instead look at them as...

What are your thoughts of having multiple SPAs?

37:17 – Guest.

39:08 – Guest: I wonder what your opinions are? What about the splitting approach?

39:22 – Panel: I haven’t looked at it, yet. I am curious, though. I have been developing in GO lately.

40:20 – Guest: I think people can go too far and making it too complex. You don’t want to make the code that complex.

40:45 – Panel: Yeah when the code is “clean” but difficult to discover that’s not good.

41:15 – Guest: I agree when you start repeating yourself then it makes it more difficult.

41:35 – Panel: Chris and I are anti-framework. We prefer to start from a fresh palette and see if a framework can fit into that fresh palette. When you start with a certain framework you are starting with certain configurations set-in-place. 

42:48 – Joe: I like my frameworks and I think you are crazy!

43:05 – Panel.

43:11 – Joe: I have a love affair with all frameworks.

43:19 – Panel: I think I am somewhere in the middle.

43:49 – Panel: I don’t think frameworks are all bad but I want to say that it’s smart to not make it too complex upfront. Learn and grow.

44:28 – Guest: I think a good example of that is jQuery, right?

45:10 – Panelist talks about C++, jQuery, among other things.

45:34 – Guest: Frameworks kind of push the limits.

46:08 – Panelist talks about JavaScript, frameworks, and others.

47:04 – Panel: It seems simple to setup routes – anything to help with the lazy way to setup?

47:35 – Guest answers question.

48:37 – Panel: How do we manage complexity and how does messaging work between components?

48:54 – Guest: The simple scenario is that you can follow a simple pattern, which is (came out of Ember community) and that is...Data Down & Actions Up!

50:45 – Guest mentions that Aurelia website!

51:00 – Panel: That sounds great! Sounds like the pattern can be plugged in easily into Aurelia.

Special Guest: Ryan Duffy 

In this episode of JavaScript Jabber, the panelists talk with Ryan Duffy who works on the EnactJS framework at LG Electronics. Ryan explains the framework in depth and answers all the questions about its design and implementation from the panelists and discusses some challenges faced along the way. Check it out!

Show Notes:

00:28 – Advertisement - KendoUI

1:08 - Ryan introduces himself and explains a bit about the EnactJS framework. While giving some background, he says that it is the 3rd generation of web frameworks that supports apps on webOS and they started building Enact on top of React about two years ago.

2:00 - Aimee asks what exactly does webOS mean. Ryan answers that webOS was created by Palm for phones and related devices and it has several instances of chromium running on device with some service layer stuff.

2:36 - Aaron mentions that webOS was big when other operating systems were still coming up, and Ryan agrees saying that it didn’t get the adoption needed to make it successful later.

3:00 - Ryan says that he always loved building apps for webOS phones given the flexibility and ease coming from a web development background.

3:53 - Aaron asks on which other applications is webOS running other than TV. Ryan answers that TV is one of the major consumptions, and it also runs on certain robots such as the concierge ones, watches to some extent and a lot of projects internally, not yet released in the market.

4:50 - Aaron asks if the Enact framework is big internally at LG. Ryan replies that it is the primary framework used for apps running on webOS.

5:03 - Aaron enquires about the nature of adoption of Enact for third party or non-LG people, to which Ryan states that Enact remains the standard framework for people who are building apps.

5:32 - Joe joins in the conversation.

6:25 - Aaron remarks that given that webOS is used in latest robots, televisions, watches and other such apps, it sounds like they are heavily investing into it. Ryan affirms by saying that the webOS journey goes from Palm phones to HP tablets to finally coming to LG. He goes on to explain their team structure, stating that there are two major teams in play right now - the R&D team is in the US and the implementation team is in Korea.

8:00 - Aaron asks about the role their team plays in the app development. Ryan replies that his team is the stack team that forms the foundation for the apps and they take decisions on what the components should look like and similar tasks. The app teams based in Korea decide their menu based on those decisions.

8:35 - Aaron asks what exactly is meant by the Blink team. Ryan answers that the it’s the team that works with an LG customized version of chromium.

9:10 – Aaron then asks about his individual role in the team. Ryan says that he is one of the managers of the stack team and he’s been on the team for little more than 4 years.

9:30 - Aaron asks about the evolution of the framework over time. Ryan describes the historical background by saying that in the initial Enyo design the team built, was component based, and every tool needed to build single page apps had to be developed from scratch. He says that they felt the need to move on to an improved framework as they wanted to take advantage of the robust ecosystem that existed, so they ported component libraries of Enyo using the React toolset to form Enact.

11:43 - Aaron asks if Enyo then ceased to exist to which Ryan states that it is still around to some extent.

12:20 - Aaron asks if the team has something like “create Enact app” to create a new app internally, like React. Ryan mentions that Jason - a tooling and automation expert from their team has built a feature called V8 snapshot - which loads JavaScript into memory and takes a snapshot - can in turn be loaded by the TV to launch the app in order to achieve a faster load time. He says that their long-term goal is to increase compatibility with the ecosystem.

14:40 - Aaron asks if he can use the React CLI to create something for TV as a third-party developer. Ryan elaborates that CLI can be used to build, compile and bundle apps and there is another tool- SDK to bundle it for delivery to the TV. The app is tested fully in chrome, bundled and deployed to the TV.

15:25 - Aaron asks if choosing React was a natural decision for the team. Ryan explains that they researched on some component-based frameworks that were available at that time and found that React was the best choice.

17:30 - Aimee asks the reason for open sourcing the framework. Ryan mentions that Enyo always has been open source. He also remarks that the team does not get a lot of input from the community and would like to get more information about what’s working and what’s not and how they can contribute back.

19:40 - Aaron asks about the kind of apps can be built by using Enact except for TV. Ryan says that any kind can be built but the hesitation is that the UI library is specially designed for TV, so they may look different for other spaces like phones or other devices.

20:35 – Advertisement – Sentry – Use the code “devchat” to get two months free on Sentry’s small plan.

21:30 - Aaron asks what decisions around making apps are made by Enact for the developers. Ryan explains that the architectural pattern they have chosen is higher order components, and there is a lot of attention on render props that can be easily plugged into the apps.

22:48 - Aaron asks if the state part was built by the team on their own. Ryan answers in affirmative that everything in Enact is completely built by the team, no external states are used within the framework. No decisions are made in the data space yet. He mentions that they had tried to limit their Enact development effort in cases where the solution was already available unless they had a new perspective on the problem.

24:30 - Aaron remarks the idea of Enact being something like a webpack is becoming clearer for him and asks Ryan if his team is spending most of their time in building component libraries. Ryan affirms by explaining that Enact is designed in layers. He goes on to explain that focus management is a difficult problem to solve where the ability to navigate an application intuitively such as in the case of remote control is handled by a certain component. Also, as LG ships TVs all over the world, there are significant internationalization requirements. He then elucidates the TV centric moonstone library in detail and states that they took all the base capabilities from it and formed a UI layer.

27:26 - Aaron asks if moonstone is theme-able. Ryan says that it’s not and the UI layer in not styled.

28:40 - Chris asks, as someone who manages open source projects and builds tools, about the process of making decisions on the kind of components to include and challenges Ryan and his team faced in the open source space.

29:45 – Ryan says that they haven’t had the ideal open source experience yet. They do have a lot of discussions on API design and components but it’s a struggle to what to include and what to not.

31:25 - Chris shares his own experience while stating that finding a common ground is always hard especially when there is internal resistance in convincing people to use new software. Ryan says that internally their biggest struggle is that a group of people use the Qt platform and there is chunk of webOS that is built on it and not on Enact. Trying to convince people to do the migration from Enyo to Enact was difficult but they have had most success in trying to eliminate friction and it was easier in the sense that there weren’t any required parameters for things.

36:05 – Aaron states that all his questions are answered and his understanding of Enact is clear.

Summary

Gareth McCumskey introduces JAMstack and serverless. He goes into great detail on how it works. Aimee Knight and Aaron Frost voice their concerns about going serverless. Aimee thinks it feels dirty. Aaron has concerns about the code, is it actually easier, what use cases would he use it for, and does it actually save money. Gareth addresses these concerns and the rest of the panel considers the positive and negatives of using JAMstack and serverless. Charles Max Wood asks for specific use cases; Gareth supplies many uses cases and the benefits that each of these cases.

Dean is a developer from Chicago and was previously on React Round Up 083. Today he has come over to JavaScript Jabber to talk about reactive programming and Storybook. Reactive programming is the opposite of imperative programming, where it will change exactly when needed instead of change only when told to. Reactivity existed long before React, and Dean talks about his history with reactive programming. He illustrates this difference by talking about Trello and Jira. In Trello, as you move cards from swimlane to another swimlane, everyone on the board sees those changes right away. In Jira,  if you have 11 tabs open, and you update data in one tab, probably 10 of your tabs are stale now and you might have to refresh. Reactive programming is the difference between Trello and Jira.

The panel discusses why reactive JavaScript is not more widely used. People now tend to look for more focused tools to solve a particular part of the problem than an all in one tool like Meteor.js. Dean talks about the problems that Storybook solves. Storybook has hot reloading environments in frontend components, so you don’t need the backend to run. Storybook also allows you to create a catalogue of UI states. JC and Dean talk about how Storybook could create opportunities for collaboration between engineers and designers. They discuss some causes of breakage that automation could help solve, such as styles not being applied properly and internationalization issues. Dean shares how to solve some network issues, such as having operators in RxJs. RxJs is useful for overlapping calls because it was built with cancelability from the beginning. 

Dean talks about his tool Storybook Animate, which allows you to see what the user sees. Storybook is an actively updated product, and Dean talks about how to get started with it. The show concludes with Dean talking about some things coming down the pipe and how he is actively involved in looking for good general solutions to help people write bulletproof code.

This cohort study compares the characteristics and management of acute heart failure in global regions comprising 44 countries.

In the Original Investigation titled “Prognostic Models Derived in PARADIGM-HF and Validated in ATMOSPHERE and the Swedish Heart Failure Registry to Predict Mortality and Morbidity in Chronic Heart Failure,” published online January 29, 2020, there was an error in the second sentence of the Results section of the Abstract. The denominator for the number of participants should be 8399, so that the sentence reads “The mean (SD) age of participants was 64 (11.4) years, 78.2% were men (n = 6567 of 8399), and 70.6% were New York Heart Association class II (n = 8399).” This article has been corrected online.
