mobx in react tutorial the basics

certainly! mobx is a state management library that makes it simple to connect your react components to a state. it allows you to manage the state in a reactive way, meaning that any change in the state automatically updates the ui.

getting started with mobx in react

1. setting up your project

first, you'll need to create a new react application. if you haven't done this yet, you can use create react app:

next, you need to install mobx and the mobx react bindings:

2. understanding mobx concepts

mobx revolves around three core concepts:

- **observables**: state that can be observed.
- **actions**: functions that modify the state.
- **reactions**: anything that reacts to changes in observables (like react components).

3. creating a simple counter example

let's create a simple counter application to demonstrate mobx.

**step 1: create a store**

**step 2: create a react component**

**step 3: run your application**

now you can run your application to see mobx in action:

you should see a simple counter application. clicking the "increment" button will increase the counter, and clicking the "decrement" button will decrease it.

explanation of the code

1. **counterstore**:
- `makeautoobservable(this)`: this function makes all properties and functions in the class observable and action automatically.
- `count`: the state variable that holds the counter value.
- `increment` and `decrement`: these are actions that modify the counter state.

2. **observer**:
- the `observer` function from `mobx-react` is used to turn the component into a reactive component. whenever the `count` changes, the component will automatically re-render.

3. **buttons**:
- the `onclick` handlers call the respective methods from the `counterstore` to update the state.
