✨ In September 2024, The React Native Show has become React Universe On Air ✨  The Coffee Talk episode is a treat. Łukasz Chludziński (https://twitter.com/loginlukasza) invited Michał Pierzchała, Head of Technology at Callstack (https://twitter.com/thymikee), and Jonny Burger, Creative Hacker at Remotion (https://twitter.com/JNYBGR) to talk about NPM Kiosk and open source monetization. As both Michał and Jonny experimented with gated access to libraries. Michał’s last open-source project, Reassure (which he developed with Maciej Jastrzębski https://twitter.com/mdj_dev), had Beta access when it was released last June. The goal was to gather some feedback from early adopters. Michał and Maciej opted for a private registry to grant Beta access to their library. Jonny, the creator of Remotion, wanted to experiment with selling specific components. As Jonny couldn’t find any tool that would solve all his problems and be easy for the buyer, he decided to hack his project – NPM Kiosk. What are the drawbacks and benefits of each option? What would they’ve done differently? How do you handle payment options? Tune in to find answers to these and other questions!

In this episode of React Universe On Air (formerly known as The React Native Show), Łukasz Chludziński (https://twitter.com/loginlukasza) and Ola Desmurs-Linczewska (https://twitter.com/p_syche_) discuss state management in React Native apps. As there’s no magical formula for handling it, don’t expect straightforward direction or easy answers from this episode. Instead, get ready for: - an overview of state management in React Native & React apps - a deep-dive into state management libraries based on different philosophies, including Redux, MobX, XState, Jotai, and React Query - an insight into how Ola compared these libraries when writing “Simplifying State Management in React Native” - a few words of the book-writing process as seen by Ola You can find Ola’s book on Amazon (https://www.amazon.com/Simplifying-State-Management-React-Native/dp/1803235039) and GitHub (https://github.com/PacktPublishing/Simplifying-State-Management-in-React-Native). New state management libraries keep appearing, so choosing the one that best suits your project and taste may be challenging. We hope to help you make this decision and get a broader perspective on state management in React Native by having Ola and Łukasz discuss the following aspects of a few libraries: - the people behind them - the category they belong, e.g. flux vs. proxy vs. atom, mutable vs. immutable, battle-tested vs. experimental - how they work and what it means to the developer Resources that Ola and Łukasz mentioned in this episode: ➡️ Dan Abramov’s Fundamentals of Redux Course https://egghead.io/courses/fundamentals-of-redux-course-from-dan-abramov-bd5cc867 ➡️ Michel Weststrate’s courses on Mobx https://egghead.io/courses/manage-complex-state-in-react-apps-with-mobx, https://egghead.io/courses/manage-application-state-with-mobx-state-tree ➡️ State explosion https://statecharts.dev/state-machine-state-explosion.html ➡️ Daishi Kato’s course on Mobx https://egghead.io/courses/manage-application-state-with-jotai-atoms-2c3a29f0 ➡️ Dominik Dorfmeister’s blog about React Query https://tkdodo.eu/blog/practical-react-query Enjoy the episode, and don’t forget to subscribe to our channel for more content like this!

✨ In September 2024, The React Native Show has become React Universe On Air ✨  Let’s dive into the topic of module federation! This time our host, Łukasz Chludziński (https://twitter.com/loginlukasza), invited two experts – Zack Jackson (https://twitter.com/scriptedalchemy), the creator of Webpack, and Paweł Trysła (https://twitter.com/_zamotany), who is the brain behind Re.Pack. Paweł was already a guest in one of our podcast episodes, where he talked extensively about bringing Webpack to React Native (https://www.callstack.com/podcasts/re-pack-bringing-webpack-to-react-native). If you want to know more about Re.Pack, take a listen! Pawel joined us for this episode because the new version of Re.Pack, Re.Pack 3.0 was released in September. It includes a new API for Module Federation in React Native and long-awaited documentation. In this episode we focus on Module Federation – an answer to, uh, complexity of publishing shared common code in the NPM packages. To make this talk a comprehensive take on Module Federation on mobile and web, we invited Zack Jackson. Zack elaborated on how he got involved in Webpack and how he came up with the crazy idea of Module Federation. In this episode, Zack, Paweł, and Łukasz discuss: Webpack similarities in web and mobile, the use cases of Module Federation on the web, and how it helps solve organizational agility problems, the idea behind bringing Webpack to React Native ecosystem and incorporating Module Federation, the use cases of Module Federation in the mobile application world, and the common pitfalls of Module Federation. In the end, our hosts and his guests discuss the buzzwords: Super apps micro frontends, and distributed systems.

In this episode of React Universe On Air (formerly known as The React Native Show), Łukasz Chludziński (https://twitter.com/loginlukasza) dives deep into one of the hottest topics in the industry – React Native’s new architecture. Together with Nicola Corti (https://twitter.com/cortinico), Senior Android Developer at Meta, they explain in-depth the main concepts around React Native’s new architecture. From this episode, you’ll discover: How was React Native created, how the framework evolved, and why it needed new architecture? What was the decision-making process behind restructuring the architecture of React Native? Nico and Łukasz discuss the pillars of the new architecture: - new render - turbo modules - codegen - the bridge After elaborating on the pillars of the new React Native architecture, Nico describes the difference between new and old React Native architecture. Nico shares some elevator pitches for the React Native new architecture and its pillars. In the next section, Łukasz and Nico talk about modern languages in native development and how they are impacted by the new architecture. Nico mentions languages such as: - TypeScript - Kotlin, and - Java Afterward, Nico and Łukasz dive deep into the benefits of switching to the React Native new architecture. There are plenty of advantages in the long run, for example, codegen will save you a lot of runtime crashes. Next, the discussion shifts to some practical aspects, namely, adopting React Native new architecture. Nico clarifies whether it’s advisable to migrate to the new architecture gradually. The conversation ends with Nico’s insights on what’s coming up with the new architecture in the near future.
