## README

# 🦀 JSX control statements for swc

Original idea: [babel-plugin-jsx-control-statements](https://github.com/AlexGilleran/jsx-control-statements)

## Installation

**pnpm** (recommended):

```shell
pnpm i -D swc-plugin-jsx-control-statements
```

or **yarn**

```shell
yarn add -D swc-plugin-jsx-control-statements
```

## Configure `swc`

In your SWC config, you have to add to [`jsc.experimental.plugins`](https://swc.rs/docs/configuration/compilation#jscexperimentalplugins) - `['swc-plugin-jsx-control-statements', {}]`, like in the following code:

```javascript
jsc: {
    experimental: {
        plugins: [
            ['swc-plugin-jsx-control-statements', {}],
        ],
    },
},
```

## Usage

### `<If>` tag

```jsx
import React from 'react';

const Greeting = () => {
    const [closed, setClosed] = useState(false);

    return (
        <>
            <If condition={!closed}>
                Hello,
            </If>
            World
            <If condition={!closed}>
                <button onClick={() => setClosed(true)}>Close</button>
            </If>
        </>
    )
};
```

### `<Choose>` tag (if - else if - else condition)

```jsx
import React from 'react';

const Greeting = () => {
    const [closed, setClosed] = useState(false);

    return (
        <>
            <Choose>
                <When condition={!closed}>
                    Hello,
                </When>
                <Otherwise>
                    Bye,
                </Otherwise>
            </Choose>
            World
            <If condition={!closed}>
                <button onClick={() => setClosed(true)}>Close</button>
            </If>
        </>
    )
};
```

### `For` tag (like array map function)

```jsx
import React from 'react';

const TodoList = ({ items }) => {
    return (
        <For each="item" of={items}>
            <span key={item.id}>{item.title}</span>
        </For>
    );
};
```

> [!WARNING]  
> using the index as key attribute is not stable if the array changes
>
> ```tsx
> <For each="item" index="idx" of={[1, 2, 3]}>
>   <span key={idx}>{item}</span>
>   <span key={`${idx}_2`}>Static Text</span>
> </For>
>```

### `With` tag

#### Simple

```jsx
import React from 'react';

const SomeComponent = ({ items }) => {
    return (
        <With foo={47} bar="test">
            <span>{foo}</span>
            <span>{bar}</span>
        </With>
    );
};
```

#### Nested

```jsx
import React from 'react';

const SomeComponent = ({ items }) => {
    return (
        <With foo={47}>
            <With bar="test">
                <span>{foo}</span>
                <span>{bar}</span>
            </With>
        </With>
    );
};
```
