New project coming: Local-only calories tracker app A key component of a local-first app is a local data store This is how to implement a local postgres database 👇 www.typeonce.dev/course/calor... @drizzle.team @pglite.dev @tailwindcss.com @vite.dev @tanstack.com @effect-ts.bsky.social

Last release of the year in the newsletter, with a look back at everything that happened in 2024 And it happened a lot 🤯 www.sandromaglione.com/newsletter

✨ TypeScript tip ✨ A function that returns Tagged Classes 👉 Type a class with `new () => T` 👉 Required `Tag` type and value 👉 Return a class with `_tag` Call the function from `extends` to get the class 🪄

My writing 101 tips in this week newsletter I have been writing on the web for (more than) a few years now Exploring my setup and process this week 👇 www.sandromaglione.com/newsletter

The example that made me get CSS subgrid ✨ A superpower that can be used for many layouts www.typeonce.dev/article/the-...

Articles are coming to typeonce.dev 👀 For everything that doesn’t require long explanations, but just short and to-the-point examples 👇

New update on pubdev with package download count 👀 Turns out fpdart is downloaded 90_000 times each week 🙌 (number formatting intended)

This is what you get when you bet on @effect-ts.bsky.social and the community around it ✨

✨ TypeScript Tip ✨ Rest parameters: Allow passing any number of arguments to a function Make your API easier to use, avoiding multiple function calls 🤝

✨ TypeScript Tip ✨ Function overloads with types 👉 Wrap type in `{}` 👉 Provide 2 different signatures Allows to call the same function with different parameters, and different results Runtime problems may apply 🙌 This pattern is useful in library-land to provide a better API for the end user

Programming literacy in this week newsletter 💡 > The ability to read, write, and understand code; programming concepts, syntax, and semantics, as well as applying skills to solve problems and communicate ideas sandromaglione.com/newsletter

✨ Introducing ECS for TypeScript ✨ typeonce/ecs is a zero dependencies library to bring the Entity Component System pattern in your game Simple, working with any renderer, type safe and composable 🕹️ github.com/typeonce-dev...

Systems in ECS just got a simple as it gets 🕹️ Define systems, dependencies, and input all type safe and inferred for you ☑️ Components ☑️ Systems ☑️ Entities Closer to the full API 🔜

ECS + @pixijs.com + MatterJS = 🕹️ Compose systems to build a complex game with physics and rendering ECS keeps everything organized and under control 🫡

Have you ever considered making a game? Well, then you should learn about Entity Component System 🕹️ An introduction for you in this week newsletter 👇 sandromaglione.com/newsletter

Integrate physics with matterjs and ECS in your game 🧱 Each system as simple as it gets, a function and a query is all you need 👇

Making the API as simple and safe in my ECS in TypeScript 🕹️ Define a component with a simple class, auto tagged and ready to use Simple and safe 🪄

Working Entity Component System with TypeScript in action 🕹️ Simple architecture for organised code and powerful results 👇

ECS implementation in TypeScript achieved 🫡 TypeScript only, extensible, working with any renderer, type safe and composable 🕹️ May be the beginning of something #game-development #typescript #games #ecs

Entity Component System (ECS) brings composability to game development 🪄 Split data and logic, and just compose entities with what they need to operate Clean, composable and powerful 🔥

Local-only calories tracker app project out now 🚀 Learn how to build a client-only app with database included in the browser with PGLite 🐘 @effect-ts.bsky.social + @drizzle.team + @tanstack.com router + XState www.typeonce.dev/course/calor...

Functional programming in games? 🤨 I have been exploring a deep hole this week, and I may have found something Some ideas in this week newsletter 👇 www.sandromaglione.com/newsletter

Upcoming local-only project is going to be an interesting one 🫡 Local database with @effect-ts.bsky.social schemas, migrations, XState state management, @tanstack.com router and more 🪄 Preview link: www.typeonce.dev/course/calor...

Add URL state to this and you have everything that you need 🤝

@tailwindcss.com v4 is out in beta 🚀 I have been using v4 for months now (early alpha) It empowers all my projects 🪄 No more js, configuration CSS only 🫡 Automatic source detection 💯 New custom utilities 🏗️ New custom variants And never came back 👇

Introduce yourself with four video games 🕹️

Stoked to announce that TanStack Start is now officially BETA! 🎉 🎊 Please come and try it and help us get it ready for 1.0! tanstack.com/start cc @tanstack.com

The database is coming to the client 🔬 Exploring local first and databases on the browser with PGLite, @drizzle.team and @livestore.dev All in this week newsletter 👇 sandromaglione.com/newsletter

Can't wait for next week! Getting ready for a big @expo.dev x @livestore.dev announcement!

Experiments with database migrations in local app 🔬 Migrations generated using @drizzle.team, loaded from @vite.dev and applied to PGLite All inside initial @tanstack.com Router loader

The expressiveness and elegance of this API is glaring 🤩 👉 No need of explicit input using `flow` 👉 Type safe validation with `decode` 👉 Easy error handling with @EffectTS_ 👉 Type safe SQL query with PGLite and @DrizzleORM Abstraction and safety 🤙

Getting fancy with form validation 🪄 React Aria components + State management with XState + Validation with @effect-ts.bsky.social schema Full control and power 💯

My top 3 skills to learn as a software developer 1️⃣ SQL and relational databases 2️⃣ Domain modeling and data structures 3️⃣ Functional programming This is the topic of this week's newsletter, going over these in practice 👇 sandromaglione.com/newsletter

Live queries with PGLite and @drizzle.team 👉 Compose query using drizzle 👉 `toSQL` to extract raw query and params Exactly what it's needed inside `useLiveQuery` to make PGLite live sync with db changes ⚡️

Wondering how to use Effect in your frontend client? As easy as it gets 🪄 Example of reading and writing into localStorage, all a single layer away 👇

Stripe payments in React with XState and Effect ☑️ Predictable using state machine ☑️ Error handling with Effect ☑️ Complete type-safety Full free code snippet 👇 www.typeonce.dev/snippet/stri...

Can't beat the simplicity of Effect error handling 🪄 Just yield a TaggedError to move the value in the error channel, or return a normal value at the end when successful 👇

Problems with cookies? 👀 Effect has them ready for you Declarative and type safe API to manage cookies baked and ready to consume 👨‍🍳

Loading environmental variables using dotenv? Effect solve this for you as well 🤝 No need to install dotenv at all, just use PlatformConfigProvider to extract env from a file 🪄

Ever heard of event sourcing? 🤔 It may be the solution to make real local-first possible Everything that I learned in this week newsletter 👇 sandromaglione.com/newsletter
