Using TypeScript with Key/Value Databases
Key-value databases are optimized for high availability and partition tolerance, making them ideal for storing non-relational data structures. They prioritize speed and high availability over consistency, making them suitable for simple data models or one-to-one mappings. However, they have limited query capabilities compared to relational databases. Some available options for key-value databases include DynamoDB, CloudFlare Worker KV, Redis, and FoundationDB. Using key-value databases in TypeScript requires addressing challenges such as serialization, deserialization, secondary indexes, relationships, and validation. The Talk includes a demonstration of an application that showcases the use of secondary indexes and the implementation of a key-value database in Deno or Redis.

Exploring the TypeScript-first architecture of modern frameworks
Hi, everyone. Today, I'll be showing you some of the features that modern frameworks implement or frameworks that leverage Typescript implement to improve the developer and user experience. I'll cover some of the features that Expo with Expo Router and Next.js with the AppRouter implements. Let's talk about setting up TypeScript in both Expo and Next.js. Both frameworks provide a TypeScript-first development experience. The most important feature is type safe routing, which enhances developer productivity and app stability. Frameworks provide a built-in link component for link generation. It reduces the risk of typos and throws type errors when linking to non-existent routes. In Expo, enable the .typed experiment and import the link component from the exporouter package. Expo supports static and dynamic routes, and throws errors for incorrect parameters. ExpoRouter provides hooks like UseSegments and UseRouter for more control. In Next.js, enable typedRoutes in the next config file. We can import the link component from the next link package and restart the dev server after updating the next config file. Next.js automatically generates route definitions and includes the type file in the TS config. Autocompletion is available for the href attribute, which can be a string or dynamic value. Next.js provides hooks like use router for static navigation and router.push to prevent redirection to broken routes. Catch all routes in type safe routing pose a challenge for enforcing type safety on the href attribute. TypeScript may not throw an error for routes that may be broken or lead to unwanted pages. Keep this in mind when working with catch all routes. Before a production build, route types should be in place to ensure accurate type definitions. Generating routes is an ongoing task that needs to happen at the right moment to avoid build-time errors. When implemented correctly, type-safe routes can elevate the developer experience by preventing broken links or dysfunctional routes. In Next.js, server components and client components have different limitations. Next.js provides automatic error checking for importing useState in server components and enforces the useClientDirective to prevent using client-related code in the wrong places. Next.js also ensures type safety by throwing errors for invalid segment config options and requiring the alt attribute for image components to improve accessibility. Config files in Expo and Next.js have different approaches to incorporating TypeScript, with Expo using the TS node require hook and Next.js supporting type checking through jsdoc in the config JS file. By enabling type-safe routing, we catch potential issues at compile time, ensuring robust routes and unbroken links. Many other frameworks and tools leverage TypeScript to empower developers and deliver error-free experiences to users.

Travis Tykemany3 McGeehan, a full-stack developer at Gordon Food Services and an administrator for the TaskBot team and ambassador from Task Videos, discusses preserving retro game footage from the TAS scene for modern viewers with WebGL. He explains the role of TaskBot, a player piano for retro game consoles, and how the TaskBot team translates tool assisted speedruns to create the fastest possible sequence of inputs. He also highlights the core problems in video game footage archival, including chroma subsampling and stretched aspect ratios in small resolutions. Challenges in retro game footage preservation include storing records at the original, unstretched resolutions and avoiding bilinear interpolation. Different algorithms, such as point and Area, produce distinct effects when scaling up images. Techniques used on rgbscaler.com to preserve crisp footage of low-resolution GameBoy games include the use of the area algorithm, AV1 and H265 encoded videos, and the ability to play videos with CRT effects. The AV1 and H.265 video codecs are used to support lossless footage and proper upscaling of pixel art footage. A custom canvas with custom controls is created using React to blow up the video in WebGL, and the area scaling algorithm is used instead of bilinear. The WebGL texture updates using a render loop, and the shader logic recreates the mask and scan lines based on pixel position. The React RGB Scaler library enables syntax highlighting for the vertex shader and the fragment shader, making development easier. The RGB scaler site demonstrates the value of improving video quality while using significantly less bandwidth than YouTube.

Between burnout, toxic workplaces, the pandemic, the economic downturn, hustle culture, and constant upskilling, let's enjoy the journey instead of slogging through it. Introducing the idea of taking a mini-retirement while working, starting with a sabbatical. Companies offer sabbaticals as a perk, allowing personal development and a chance to return to work. Many companies have publicly stated sabbatical programs, like Adobe. Requirements are guidelines, not set in stone. And they offered it to me anyway by way of apology. Everything worked out, our mini-retirement lasted six months. In fact, the benefits of extended time off are something the rest of the world seems to understand, but the US hasn't gotten the memo. What about those of you who don't have access to a sabbatical? Is there another kind of mini-retirement you could pull off? Absolutely. You can check if you have the ability to request an unpaid personal leave of absence. Unlike a sabbatical, there's no guarantee you'll have a job waiting for you when you get back, but you can request it for any reason at any time. Great, but how can you do this? So let's talk logistics. A mini retirement is within reach for a lot of people. Here's a worksheet to help you plan your mini retirement. Determine your cash in and cash out to calculate your savings rate. You can choose how many months you want to take off and calculate the amount of money you need to save. Your savings rate reveals important information about your finances. Saving 10% to 20% can cut the time needed in half, and saving 30% per month allows you to work from September to May and save for your summer off. There are some considerations, such as paying for benefits out-of-pocket and pausing contributions to retirement accounts.

Vuex to Pinia. How to Migrate an Existing App
Top Content
Pinia is the officially recognized state management library for Vue.js, with a simpler API than VueX and TypeScript support. Migrating to Pinia involves creating a root store, defining stores, and using store2refs or the exported use store in components. Testing real store behavior requires creating a Pinia instance, while component testing involves importing useStore and using mapState and mapAction from vigname. Migrating tests involves creating a local view and using the Pinia plugin, and Vuex and Pinia can coexist but should be migrated module by module. Store persistence can be achieved through subscribing to store changes or using a watcher.

Sharing is Caring: (How) Should Micro Frontends Share State?
Top Content
Micro-frontends allow development teams to work autonomously and with less friction and limitations. Organizing teams around business concerns, in alignment with subdomains, rather than technical concerns, can lead to software that is split nicely and user stories falling under the responsibility of a single team. Having a logical backup or reference point is important for implementing microfrontends without breaking their isolation. Microfrontends can communicate with each other using the window object and custom events. Microfrontends should be kept isolated while maintaining communication through various approaches.

The Eternal Sunshine of the Zero Build Pipeline
For many years, we have migrated all our devtools to Node.js for the sake of simplicity: a common language (JS/TS), a large ecosystem (NPM), and a powerful engine. In the meantime, we moved a lot of computation tasks to the client-side thanks to PWA and JavaScript Hegemony.
So we made Webapps for years, developing with awesome reactive frameworks and bundling a lot of dependencies. We progressively moved from our simplicity to complex apps toolchains. We've become the new Java-like ecosystem. It sucks.
It's 2021, we've got a lot of new technologies to sustain our Users eXperience. It's time to have a break and rethink our tools rather than going faster and faster in the same direction. It's time to redesign the Developer eXperience. It's time for a bundle-free dev environment. It's time to embrace a new frontend building philosophy, still with our lovely JavaScript.

System-level state management in modern React applications is challenging. Usually, as the applications grow, the complexity of interaction between different parts of the application compounds. The more you need those isolated parts to talk, the higher the level of complexity. Usually, the common pitfalls of these communications are underestimated especially with the recent trend of State management that tends to keep the application state outside of React and distributed. In this talk, We'll see how the Actor Model architecture can come to the rescue and what makes it stand out compared to the other approaches.

Hooks are a great abstraction model
The discussion explores the separation of concerns between logic (Model) and UI (View) and how React hooks are a great abstraction model that help achieve that.
We'll start with designing a component's API (in a top down approach), then dive deeper to explore how to implement this API, while maintaining a good separation of concerns.
We'll create custom React hooks to implement the Model and React components for the UI. Both expose self-documenting APIs and are completely decoupled from each other.
To demo this approach, we'll create a simple Toggler component (a UI component that allows going back and forth in an array of values).Towards the end, we'll explore the benefits, focusing on testing these decoupled units in isolation.

Nx + Next.js = ❤
Hey everybody, my name is Adam Ellibert, aka Big AB, and I am a core contributor on a project called NX. Today, I'm going to go through a whirlwind tour of a really cool way to do web development using NX. NX is a suite of dev tools to improve developer experience, and it's extensible, plugin-based, and open-source. I'll show you some of the commands that NX provides, such as creating an NX workspace, generating schematics, serving as a dev server, building applications, and running tests. NX also has a variety of plugins, including the Next.js plugin. And if you're not comfortable with command-line interfaces, there's a GUI available for you. I'm going to create an NX workspace and choose Next.js as my first application. Then I'll create another app called Uber for Star and add a dashboard page. I'll also create a shared components library and configure storybook for it. Finally, I'll use NxServe to serve my Uber 4 app. This setup includes a splash page, a dashboard page, and a design system using storybook. We've got shared components for our marketing website and Uber 4 app. We also have end-to-end directories for Cypress tests and jest for unit tests. Our Uber 4 app is similar to any other Next.js app with pages and a nested dashboard page. We import shared components by prefixing them with the org name and library name. NX handles dependencies, ensuring everyone is on the same version and allows scoping imports to the org. Computation caching optimizes test and build runs by caching results that are unaffected by code changes. NX brings easy application creation with consistent commands and shared library extraction. Generators save time and enforce best practices. NX provides modern tools like Cypress, Storybook, Prettier, ESLint, and Next.js. The Next.js plugin creates and configures Next.js applications, serving them in dev mode and building production-ready and static apps. Visit nx.dev for more information.
