Show Topics: 0:32 – Panel: Thanks for joining us and talking about this https://evilmartians.com/chronicles/optimizing-react-virtual-dom-explained 0:52 – Guest: Thanks for having us on your podcast! The guest talks about his community of developers and the offices are in San Francisco, Russia and other places. He talks about how the company helps their customers and how they can scale. Some of their companies are https://www.groupon.com/?gclid=EAIaIQobChMI9Puun7Kq3gIVDo1pCh2oDgiyEAAYASAAEgJZ7_D_BwE&utm_campaign=us_dt_sea_ggl_txt_naq_sr_cbp_ch1_ybr_k%2Agroupon_m%2Ae_d%2Agroupon-brand_g%2Agroupon-exact_c%2A137872562158_ap%2A1t1&utm_medium=cpc&utm_source=google and https://www.ebay.com 2:39 – Alexey. 3:09 – Panel: The article is https://evilmartians.com/chronicles/optimizing-react-virtual-dom-explained What is JSX how does it boil down to? It’s all supposed to help people and help them understand. 3:45 – Alexey: It’s about how to structure your state, etc. 4:15 – Panel: This keeps things small. He said when I have one idea I write a song and when I have 2 ideas I write 2 songs. If you try to put too many ideas into one post it maybe won’t go too far. 4:48 – Alexey. 5:50 – Panel. 5:56 – Panel: That’s a topic for another episode. The article is interesting in that the large percentage don’t think about rendering performance, so it’s a needed piece of content. Let’s talk about – what is the https://www.codecademy.com/articles/react-virtual-dom 6:32 – Alexey goes into detail with his answer to the panelist’s question. 8:50 – Panel: What I like about this article is that you go through a good progression: here is the JSX that you would write and here is the trans piled function is. And you show the virtual DOM pre-presentation is. I think that is a helpful thing. Let’s talk about that. How does React change to those things when it’s rendering? 9:50 – Alexey. 12:58 – Panel: Okay to recap...when you are rendering an element you write some JSX and the first thing (component) that will map over to the type property is for the Virtual DOM object? And then all of that is compared – when does that happen, the comparison? 13:28 – Alexey: You have React and you create... 15:20 – Panel: So it’s both React and set state these are the only 2 things that triggered state or is there anything else out there? 15:31 – Alexey. 15:47 – Panel: Interesting. You talked about the imperative way we did it before – and it’s much simpler to say what you want, but a question is that is there any world case where it does not work well? What are the trade-offs? Have you ever encountered one? 16:34 – Alexey: If you have changes in the browse, implementations...it’s simplest and easiest way. You just need to have some little changes... 17:53 – Panel: If it’s basic then you don’t have to do manual updates. 18:03 – Alexey. Alexey: To make it work you need competence in your bundle. 18:36 – Panel: I’ve heard – haven’t worked with – when we have these projects that are really web time based, hundreds of elements in real time on a screen, on a Virtual DOM it’s too slow. You have to be precise. They had performance issues, I’m sure 98.99% of the applications probably perform better with the Virtual DOM. 19:46 – Alexey. 21:38 – Panel: That is to reduce the amount of state changes so you are reducing the amount of time it renders – right? 21:50 – Alexey. 22:03 – https://www.freshbooks.com/?ref=10400&sscid=a1k2_rph9e&utm_campaign=87321&utm_medium=affiliate&utm_source=sas 23:11 – Panel: We talked about how type is the first thing that is checked. It does equal comparison to compare these types. What was really interesting is that class components are the same thing but not so. Is it always going to re-render for those components? 24:24 – Alexey: We have to talk about 2 things about this first. In my https://evilmartians.com/chronicles/optimizing-react-virtual-dom-explained 27:49 – Panel: That is a beneficial tool too to control your rendering. You talked about tools to show updates and we will include the link to the article in the links, also I would read it and check out that particular function. It’s cool to see HOW it’s actually rendering. 28:29 – Panel: Apparently sometimes things help us in principle cause we need performance. We need to open the tools and understand what is happening? Is it really a bottleneck like I think it is? One of those Twitter things I saw a few months ago... 30:52 – Alexey: Yes, do what makes sense to you at the time. 32:08 – Panel: We talked about render performance and the pure component and not creating functions...you have a big quote in your article... I have a big question for me: You have a component, and there is a child / parent component. I am curious about that pattern – will it re-render every time? Tell us your thoughts, please. 33:16 – Alexey. 34:11 – Panel: My only issue with the render props is not a performance issue it’s more of an architectural issue. Sometimes we want things to be interjected. I want to have access to this or that. Sometimes we want to access those on a life cycle. The higher the component makes it easier to add a... That’s my only complaint about render comps. 35:35 – Alexey. 36:00 – Panel: Like composing consumers? 36:06 – Alexey: What we are talking about is... 37:00 – Panel: I agree. There are some interesting cases with that pattern when you have a lot of those chained together – function, function, etc. – there are some components that will help you compose... 37:34 – Panel: It’s like callback hell all over again. Everything is a tradeoff somewhere. After the tree it looks clean with render props. I like it even with the drawbacks. 38:25 – Panel: You spent some time talking about lists of children and how you (if one of the children are removed) then it ends up re rendering all the children cause it’s comparing their positions. You mentioned key is one way to deal with that. Let’s talk about keys. When people use keys they are using an array of an index. It seems like it defeats the purpose of it – is that right? 39:20 – Alexey: Yes, you are right. 40:19 – Panel: I think that continually and it’s a smaller known thing but people want this key error to go away and they just shove something in there. To some extent it’s good to know if your tool requires something it’s good to know WHY it requires that. 40:52 – Panel: Last question. Is that the person to program and be a web developer and they are learning React. This is the tool and they are learning how to use React for an app then when we are throwing articles at them. If they are learning React and these articles are at them I think it’s a cognitive overload. What are your thoughts / advice? 42:07 – Guest: How beginner should you be before you learn React? Ideally you should be aware of JavaScript, right? Sometimes people do this to catch up to something shiny. This is just my 2 cents. 43:03 – Alexey. 44:49 – Panel: When you are going to hire someone to do something or choose a framework always try to do a little bit of work without it. Try to build an application w/o React, and then React is introduced to you, you will only see the benefits that they are brining. One thing that happens inside the React world is that people don’t write an application... Start with the basic building blocks – that makes sense to me. 46:05 – Panel: Let’s go to picks! 46:13 – https://www.digitalocean.com/ Links:

Redux, Redux Toolkit, OSS and More with Mark Erikson - RRU 238

Returning guest Mark Erikson joins the React Round Up team to discuss how he found himself in the position of being an open source maintainer for Redux, how he's helped shepherd/author future versions of Redux (and the complete overhauls that happened when React Hooks were introcuded), and the new examples he's written for Redux Toolkit to make Redux easier for devs to get started with. Mark also addresses some commons misconceptions around React and Redux, such as: is React Context a perfect substitute for Redux (spoiler: it's not), and is Redux still relevant today (it is). Take a listen to hear about getting into open source, where Redux is headed and Mark's broader thoughts on helping the React community document and standardize all the options out there so developers have an easier time choosing the tools needed to solve their particular problems.SponsorsChuck's Resume TemplateRaygun - Application Monitoring For Web & Mobile AppsBecome a Top 1% Dev with a Top End Devs MembershipLinksCheng Lou - On the Spectrum of Abstraction at react-europe 2016Blogged Answers: Why React Context is Not a "State Management" Tool (and Why It Doesn't Replace Redux)Coding Career AdviceGitHub | markerikson/react-community-tools-practices-cheatsheetGitHub | markerikson/react-community-tools-practices-cheatsheet - Initial RFC: Scope and Goals #1Comparison with Other FrameworksRedux Style Guide#Redux Essentials, Part 1: Redux Overview and Concepts#Redux Fundamentals, Part 1: Redux Overview#Redux ToolkitRTK QueryJavaScript for Java-ish DevelopersMark's Dev BlogTwitter: Mark Erikson ( @acemarke )GitHub | Mark EriksonPicksCarl- Writing for Software Developers by Philip Kiely Mark- Josh ComeauPaige- Open source password manager - BitwardenTJ- Bowflex SelectTech DumbbellsZain- GitHub | zalmoxisus/redux-devtools-extensionAdvertising Inquiries: https://redcircle.com/brandsPrivacy & Opt-Out: https://redcircle.com/privacyBecome a supporter of this podcast: https://www.spreaker.com/podcast/react-round-up--6102072/support.

How Do I Introduce New Tech at Work? - RRU 237

Today the panel is discussing how to introduce new tech at work. They agree that it’s important to get input from all teams on the decision, although it will primarily affect the development team. One should also consider the different ways people make decisions, such as through discussion or quiet thinking, and give everyone time to come to a decision. The panel talks about positive and negative examples of how to introduce new tech at work. Thomas believes that it is important to acknowledge your own biases in decision making and to try to avoid them. The React experts discuss the significance of the team dynamic and the necessity of different roles in decision making or if it is better to have an organic discovery phase. This relates to Thomas’ point about personal biases, and he believes that it is important to put people in roles that are opposite of their personality. When making decisions about new technology, it is also important to note that not all decisions require the same amount of input, and they discuss how to measure how much input is required for a decision.SponsorsChuck's Resume TemplateRaygun - Application Monitoring For Web & Mobile AppsBecome a Top 1% Dev with a Top End Devs MembershipLinksVue12 React Best Practices You Need to Follow in 2019SaulTest && commit || revertVS Code ESLintPicksThomas - Teachable MachineCharles - White ChristmasCharles - Holiday InnChris - Practical React HooksAdvertising Inquiries: https://redcircle.com/brandsPrivacy & Opt-Out: https://redcircle.com/privacyBecome a supporter of this podcast: https://www.spreaker.com/podcast/react-round-up--6102072/support.

Navigating React Navigation with Zain Sajjad - RRU 236

Zain Sajjad is a frontend developer at his company Peekaboo Guru, an app built in React. The show begins with Zain explaining why he chose to build Peekaboo Guru in React. Ultimately, he chose React for its composability and reusability. He talks about how much data is shared between his React and React Native applications.Zain explains what he means by a container since he is not talking about Docker, and how he has the app organized. He talks about the differences between routing and navigation between React and React Native. When approaching these differences, he breaks things down into components, containers, and platform, paying careful attention to how they work together. This differentiation can actually help a lot with testing as well.
