# babel-plugin-transform-react-jsx
> Turn JSX into React function calls
## Example
### React
**In**
```javascript
var profile = <div>
<img src="avatar.png" className="profile" />
<h3>{[user.firstName, user.lastName].join(' ')}</h3>
</div>;
```
**Out**
```javascript
var profile = React.createElement("div", null,
React.createElement("img", { src: "avatar.png", className: "profile" }),
React.createElement("h3", null, [user.firstName, user.lastName].join(" "))
);
```
### Custom
**In**
```javascript
/** @jsx dom */
var { dom } = require("deku");
var profile = <div>
<img src="avatar.png" className="profile" />
<h3>{[user.firstName, user.lastName].join(' ')}</h3>
</div>;
```
**Out**
```javascript
/** @jsx dom */
var dom = require("deku").dom;
var profile = dom( "div", null,
dom("img", { src: "avatar.png", className: "profile" }),
dom("h3", null, [user.firstName, user.lastName].join(" "))
);
```
## Installation
```sh
npm install --save-dev babel-plugin-transform-react-jsx
```
## Usage
### Via `.babelrc` (Recommended)
**.babelrc**
Without options:
```json
{
"plugins": ["transform-react-jsx"]
}
```
With options:
```json
{
"plugins": [
["transform-react-jsx", {
"pragma": "dom" // default pragma is React.createElement
}]
]
}
```
### Via CLI
```sh
babel --plugins transform-react-jsx script.js
```
### Via Node API
```javascript
require("babel-core").transform("code", {
plugins: ["transform-react-jsx"]
});
```
## Options
### `pragma`
`string`, defaults to `React.createElement`.
Replace the function used when compiling JSX expressions.
Note that the `@jsx React.DOM` pragma has been deprecated as of React v0.12
### `useBuiltIns`
`boolean`, defaults to `false`.
When spreading props, use `Object.assign` directly instead of Babel's extend helper.
