State management is a critical part of web development, and it can be challenging to get right. Fortunately, there are several open-source libraries that can help make it easier. Here are 5 top state management libraries that every web developer should know:
First up is #Zustand. This library is lightweight and flexible, making it an excellent choice for small to medium-sized applications. It uses React hooks for state management, which makes it easy to integrate with React projects. Check it out at
Next is #XState, which is a state machine library that makes it easy to manage complex application state. It uses finite state machines to model state transitions, making it a powerful tool for building robust applications. Check it out at

Learn JS Patterns - 1 Singleton
- harder to write unit test for app
- consider #Redux as a (kind of) singleton
- a bit breaks Single Responsibility Principle, because it solves two problems (keep one instance for a class, assign a global access point to the instance)

@keurplkar Learn JS Patterns - 2 Proxy Pattern

- Proxy can help on validating, formatting, notification, debugging etc
- It add control over the behavior of an object, so over using Proxy may grant performance issue

@keurplkar 3 Provider Pattern

- Very common in React, make data accessible to multiple child components to avoid props drilling
- For example #mui theme provider provider pattern diagram in...

This #TypeScriptTuesday, we're going to take a look at #TypeScript's interfaces.
Interfaces are different from types and both have their strengths in different situations.
Let's take a look.
This is just some interface definition - again an example from the #redux types:
๐Ÿงต๐Ÿ‘‡ interface Action {<br />
  type: string;<br />
An interface can also extend another interface.
Not only that, but also some (but not all) types.

The rule of thumb here is: if the type is well-known and could be written as an interface, it can be extended. // extending multiple interfaces is possible<br />
  interface StringPayloadActionWithError extends Action, WithErrorAttribute {<br />
    payload: string;<br />
  }<br />
<br />
  /**<br />
   * This can be resolved to { type: string; payload: string }, which<br />
   * could be expressed as an interface, so it can be extended.<br />
   */<br />
  interface StringPayloadAction extends Omit<StringPayloadActionWithError, {
meta: number;
}" src="/images/1px.png" data-src="">
Another feature or Interfaces are index signatures. Interfaces can be indexed only by string or number, not by union types. You need Mapped Types for that.
If you index by string and number, the value indexed by number has to be a subset of the value indexed by string. interface SomethingElse {<br />
  [key: string]: string | number;<br />
  [key: number]: number;<br />
}<br />
<br />
interface InvalidInterface {<br />
  [key: string]: string;<br />
  // Error: An index signature parameter type cannot be a union type. Consider using a mapped object type instead.ts(1337)<br />
  [key: // Error: Numeric index type 'number' is not assignable to string index type 'string'.ts(2413)
[key: number]: number;
" src="/images/1px.png" data-src="">

While last #TypeScriptTuesday we looked at #TypeScript Generics Basics, today we continue where we left off, by taking a closer look at type argument inference, pitfalls and workarounds. We will take a look at a simplified version of #redux-toolkit's `createAction` function.
๐Ÿงต๐Ÿ‘‡ interface PayloadAction<P, T = string> {<br />
  type: T;<br />
  payload: P;<br />
}<br />
<br />
type ActionCreator<P, T> = (payload: P) => PayloadAction<P, T>;<br />
<br />
function createAction<P, T = string>(type: T): ActionCreator<P, T> {<br />
  return (payload: P) => ({<br />
    type,<br />
    payload<br />
  });<br />
Here, we call this function three ways:

1. With explicit type arguments. Everything is fine.
2. With inferred type arguments. P cannot be inferred, because it does not relate to any method argument.
3. With one explicit type argument. But why is the second argument not inferred? function createAction<P, T = string>(type: T): ActionCreator<P, T> {<br />
  /* ... */<br />
}<br />
<br />
const type =
// ActionCreator
const incrementAction = createAction(type);

// ActionCreator
const actionCreator2 = createAction(type);

// ActionCreator
const actionCreator3 = createAction(type);" src="/images/1px.png" data-src="">
This is because #TypeScript cannot mix explicit and inferred type arguments.
There is a PR for that atโ€ฆ, but there is still discussion on what syntax to use.
Let's just assume that this is impossible and try to work around it.

Ok; it's #redux time:

(code link at the end)

๐Ÿ”ฅ Learn Redux in 10 tweets - with React and hooks! ๐ŸŽฃ ๐Ÿ‘‡

Redux gives you a central place to put your state (data) for JavaScript apps

It's most often used with React (via react-redux)

This lets you access or change your state from ANY component in your tree

Your state lives in a central Redux store

That store is created with a function called a reducer

A reducer takes in a state and an action,
and returns the same or a NEW state
