This is how I implement a web app: local first and PWA (progressive web apps) as architecture, and libraries like effect, XState, tailwindcss to implement the core of the app, state management, and styling.

This is my journey in learning functional programming and its core concepts, using multiple programming languages: from Lisp and Haskell, to object oriented languages like Dart and Kotlin, all the way to Typescript and the web.

Learn many powerful and advanced dart's features required to build an Effect System in dart: type system (Never, void, Null), type inference, FutureOr for synchronous and asynchronous functions.

This is my experience as the creator and maintainer of a popular open source library: how to get started, how to make a successful library, how to maintain it, and what are the results.

Learn what is an Effect system and how Effect systems are the future of programming.

The best way to explore a library is to read code written by its core maintainers.

A new paradigm to scale complexity in software applications: use types to define errors and dependencies, and use the compiler to guide the implementation and unlock local reasoning.

Different programming languages shares similar challenges.

Why should I use Effect?

Learn what actors and the actor model are and how to use them for state management.

Learn how to implement a state machine using actors in XState v5, how to organize the code for context, input, events, and actions, and how to invoke and use actors in a state machine.

It is possible to remove dependencies while also adding features and improving performance: I call this under-engineering.

Learn how to create your personal blog using Effect, NextJs, and MDX.

Learn how state management works and what problem it solves: store some state, read the state, update the state, and rerender the user interface after each change.

State management in flutter using riverpod, bloc, signals, getX: how to install them, how to define the state, how to use them in your flutter app, and their pros and cons.

How to make your first contribution to an open source project step by step: research about the topic, fork the repository, read code, complete the implementation, and send a PR.

Learn how to implement a data structure with typescript: performance, stack safety, immutability, how to make it iterable, inspectable, how to add equality and refinement.

How to learn a new library when the official documentation is not enough: use the API reference, explore and search the open source repository, read tests, ask for help from the community.

Complete introduction to using Effect in Typescript: why using Effect, what is the Effect type, how to use it, and what are the main modules of Effect.

This is how I created a state management library in dart and flutter.

Implement State Machines and Statecharts in dart and flutter: how to model a state machine, how to use generics to make the machine type-safe, and how to extend the state machine to make it a statechart.

Learn what is a state machine, how a state machine can be used to model any application, and how to use XState with Effect to implement a complete Typescript project with full type-safety.

Learn how to use XState and Effect to implement an audio player in react: stately visual editor to define the state machine, actions implemented using Effect, and use the machine in a react component.

I share my experience making a game in Flutter in 2 days for the Flame Game Jam 3.0: how to create a game from zero by yourself for a game jam with limited time and resources.

Create games in Flutter.
