# RippleAPI in Web Browsers
RippleAPI can also be used in a web browser if you compile a browser-compatible version and include [lodash](https://www.npmjs.com/package/lodash) as a dependency before the RippleAPI script.
RippleAPI can also be used in a web browser. To access it, load [Lodash](https://lodash.com/) and [RippleAPI for JavaScript (ripple-lib)](rippleapi-reference.html) in your site's HTML. For example:

```
<!-- MULTICODE_BLOCK_END -->
Instead of using Node.js's "require" syntax, the browser version creates a global variable named `ripple`, which contains the `RippleAPI` class.

## Build a Browser-Compatible Version of RippleAPI
To use RippleAPI in a browser, you need to build a browser-compatible version. The following process compiles RippleAPI into a single JavaScript file you can include in a webpage.
You can also build a browser-compatible version of the code yourself. Use the following steps to build it from the source code.

### 4. Use Gulp to build a single JavaScript output
### 4. Build with Yarn
RippleAPI comes with code to use the [gulp](http://gulpjs.com/) package to compile all its source code into browser-compatible JavaScript files. Gulp is automatically installed as one of the dependencies, so all you have to do is run it, such as with following command:
RippleAPI comes with the necessary dependencies and code to build it for the browser. Trigger the build script as follows:

```sh
yarn run build

This may take a while. At the end, the build process creates a new `build/` folder, which contains the files you want.
The file `build/ripple-<VERSION NUMBER>.js` is a straight export of RippleAPI (whatever version you built) ready to be used in browsers. The file ending in `-min.js` is the same thing, but with the content [minified](https://en.wikipedia.org/wiki/Minification_%28programming%29) for faster loading. <!-- SPELLING_IGNORE: minified -->

## Demo RippleAPI in a Browser
The following HTML file demonstrates basic usage of the browser version of RippleAPI to connect to a public `rippled` server and report information about that server. Instead of using Node.js's "require" syntax, the browser version creates a global variable named `ripple`, which contains the `RippleAPI` class.
The following HTML file demonstrates basic usage of the browser version of RippleAPI to connect to a public `rippled` server and report information about that server.
To use this example, you must first [build a browser-compatible version of RippleAPI](#build-a-browser-compatible-version-of-rippleapi) and then copy one of the resulting output files to the same folder as this HTML file. (You can use either the minified or full-size version.) Change the second `<script>` tag in this example to use the correct file name for the version of RippleAPI you built.

# Get Started
The XRP Ledger is always online and entirely public. You can access it directly from your browser with [RippleAPI for JavaScript (ripple-lib)](rippleapi-reference.html). Try experimenting with some of the following examples:
The XRP Ledger is always online and entirely public. You can access it **directly from a web browser** with a few steps described in this page. Scroll down to get started!
## 1. Prerequisites
To access the XRP Ledger from a webpage, load [Lodash](https://lodash.com/) and [RippleAPI for JavaScript (ripple-lib)](rippleapi-reference.html) in your site's HTML. For example:
```html
<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.15/lodash.js"></script>
<script src="https://unpkg.com/ripple-lib@1.8.0/build/ripple-latest-min.js"></script>
```
<!-- SPELLING_IGNORE: lodash -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.15/lodash.js"></script>
<script type="application/javascript" src="assets/js/ripple-lib-1.8.0-min.js"></script>
<link rel="stylesheet" type="text/css" href="assets/vendor/codemirror.css"/>
<script type="text/javascript" src="assets/vendor/codemirror-js-json-lint.min.js"></script>
<script src="https://unpkg.com/ripple-lib@1.8.0/build/ripple-latest-min.js"></script>
On this page, that's already done, so continue to the next step!
## 2. First Script
The following code gets the latest [ledger version](ledgers.html) and a list of transactions that were newly-validated in that ledger version, using the [`getLedger()` method](rippleapi-reference.html#getledger). Try running it as-is, or change the code and see what happens.
**Tip:** If you can, open your browser's Developer Tools by pressing **F12**. The "Console" tab provides a native JavaScript console and can give insight into what code is running on any webpage.

## 3. Next Steps
Try editing the code from step 2 to do something different:
- Connect to the [Testnet](parallel-networks.html) public server at `wss://s.altnet.rippletest.net/` instead. [Answer >](javascript:fill_ex_1())
- Look up the details of a transaction using the [`getTransaction()` method](rippleapi-reference.html#gettransaction). For the `id`, use one of the `transactionHashes` from the `getLedger()` response! [Answer >](javascript:fill_ex_2())
- Convert the `totalDrops` from the response to decimal XRP. [Answer >](javascript:fill_ex_3())
