Update links to use https:// where it is supported. There's probably a lot more that could be fixed, but these are the core ones I found (especially the download links in order to prevent MITM attacks). Note that there are some fb.me links that will redirect to http:// even while accessed over https://, but this seemed like the best way to fix those for now. NOTE: Only non-third-party files were modified. There are references to http:// URLs in vendored/third-party files, but seems appropriate to fix upstream for those rather than editing the files. Also, copy one image locally to the blog, as it was hotlinking to a site that did not support https://. Last, use youtube-nocookie.com instead of youtube.com for video embeds, as the former doesn't try to set a cookie on load (privacy enhancement).

## JSFiddle
|
|
|
|
The easiest way to start hacking on React is using the following JSFiddle Hello World examples:
|
|
|
|
* **[React JSFiddle](https://jsfiddle.net/reactjs/69z2wepo/)**
|
|
* [React JSFiddle without JSX](https://jsfiddle.net/reactjs/5vjqabv3/)
|
|
|
|
## Starter Kit
|
|
|
|
Download the starter kit to get started.
|
|
|
|
<div class="buttons-unit downloads">
|
|
<a href="/react/downloads/react-{{site.react_version}}.zip" class="button">
|
|
Download Starter Kit {{site.react_version}}
|
|
</a>
|
|
</div>
|
|
|
|
In the root directory of the starter kit, create a `helloworld.html` with the following contents.
|
|
|
|
```html
|
|
<!DOCTYPE html>
|
|
<html>
|
|
<head>
|
|
<script src="build/react.js"></script>
|
|
<script src="build/JSXTransformer.js"></script>
|
|
</head>
|
|
<body>
|
|
<div id="example"></div>
|
|
<script type="text/jsx">
|
|
React.render(
|
|
<h1>Hello, world!</h1>,
|
|
document.getElementById('example')
|
|
);
|
|
</script>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|
The XML syntax inside of JavaScript is called JSX; check out the [JSX syntax](/react/docs/jsx-in-depth.html) to learn more about it. In order to translate it to vanilla JavaScript we use `<script type="text/jsx">` and include `JSXTransformer.js` to actually perform the transformation in the browser.
|
|
|
|
### Separate File
|
|
|
|
Your React JSX code can live in a separate file. Create the following `src/helloworld.js`.
|
|
|
|
```javascript
|
|
React.render(
|
|
<h1>Hello, world!</h1>,
|
|
document.getElementById('example')
|
|
);
|
|
```
|
|
|
|
Then reference it from `helloworld.html`:
|
|
|
|
```html{10}
|
|
<script type="text/jsx" src="src/helloworld.js"></script>
|
|
```
|
|
|
|
### Offline Transform
|
|
|
|
First install the command-line tools (requires [npm](https://www.npmjs.com/)):
|
|
|
|
```
|
|
npm install -g react-tools
|
|
```
|
|
|
|
Then, translate your `src/helloworld.js` file to plain JavaScript:
|
|
|
|
```
|
|
jsx --watch src/ build/
|
|
|
|
```
|
|
|
|
The file `build/helloworld.js` is autogenerated whenever you make a change.
|
|
|
|
```javascript{2}
|
|
React.render(
|
|
React.createElement('h1', null, 'Hello, world!'),
|
|
document.getElementById('example')
|
|
);
|
|
```
|
|
|
|
|
|
Update your HTML file as below:
|
|
|
|
```html{6,10}
|
|
<!DOCTYPE html>
|
|
<html>
|
|
<head>
|
|
<title>Hello React!</title>
|
|
<script src="build/react.js"></script>
|
|
<!-- No need for JSXTransformer! -->
|
|
</head>
|
|
<body>
|
|
<div id="example"></div>
|
|
<script src="build/helloworld.js"></script>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|
## Want CommonJS?
|
|
|
|
If you want to use React with [browserify](http://browserify.org/), [webpack](https://webpack.github.io/), or another CommonJS-compatible module system, just use the [`react` npm package](https://www.npmjs.com/package/react). In addition, the `jsx` build tool can be integrated into most packaging systems (not just CommonJS) quite easily.
|
|
|
|
## Next Steps
|
|
|
|
Check out [the tutorial](/react/docs/tutorial.html) and the other examples in the starter kit's `examples` directory to learn more.

Good luck, and welcome!
