# WordPress Playground and PHP WASM (WebAssembly)
# WordPress Playground tools

[Project Page](https://developer.wordpress.org/playground/) | [Live demo](https://playground.wordpress.net/) | [Documentation and API Reference](https://wordpress.github.io/wordpress-playground/)
This repository contains the tools and applications built using [WordPress Playground](https://developer.wordpress.org/playground/):

[WordPress Playground](https://github.com/WordPress/wordpress-playground) is an experimental in-browser WordPress that runs without a PHP server thanks to the magic of WebAssembly.
- [Interactive Code Block for Gutenberg](./packages/interactive-code-block/)
- [WordPress Playground for Visual Studio Code](./packages/vscode-extension/)
- [wp-now](./packages/wp-now/)

![](https://raw.githubusercontent.com/wordpress/wordpress-playground/trunk/demo.png)

## Why is WordPress Playground useful?

WordPress Playground is a building block that can power apps like:

- Runnable code snippets in your documentation or course
- Plugin and theme demos in a private WordPress instance where the user is already logged in as an admin
- Easily switching PHP and WordPress version when testing
- Replaying and fixing the failed CI tests right in the browser

See
[the WordPress.org announcement post](https://make.wordpress.org/core/2022/09/23/client-side-webassembly-wordpress-with-no-server/) to learn more about the vision.
If you were looking for the Playground itself, you can find it here: [WordPress Playground](https://developer.wordpress.org/playground/)

## Getting started

WordPress Playground has a [live demo](https://developer.wordpress.org/playground/demo/) available.

You can embed WordPress Playground in your project via an `<iframe>` – find out how in the [documentation](https://wordpress.github.io/wordpress-playground/). **Note the embed is experimental and may break or change without a warning.**

You can connect to the Playground using the JavaScript client. Here's an example of how to do it in the browser using an `iframe` HTML element and the `startPlaygroundWeb` function from the `@wp-playground/client` package.

**index.html**:

```html
<!DOCTYPE html>
<html>
<head>
<title>WordPress Playground</title>
</head>
<body>
<iframe id="wp" style="width: 1200px; height: 800px"></iframe>
<script type="module">
import { startPlaygroundWeb } from 'https://unpkg.com/@wp-playground/client/index.js';
const client = await startPlaygroundWeb({
iframe,
remoteUrl: `https://playground.wordpress.net/remote.html`,
blueprint: {
landingPage: '/wp-admin/',
preferredVersions: {
php: '8.0',
wp: 'latest',
},
steps: [
{
step: 'login',
username: 'admin',
password: 'password',
},
{
step: 'installPlugin',
pluginZipFile: {
resource: 'wordpress.org/plugins',
slug: 'friends',
},
},
],
},
});
const response = await client.run({
code: '<?php echo "Hi!"; ',
});
console.log(response.text);
</script>
</body>
</html>
```

## Cloning the repo

The vanilla `git clone` command will take ages. Here's a faster alternative that will
only pull the latest revision of the trunk branch:

```
git clone -b trunk --single-branch --depth 1 [email protected]:WordPress/wordpress-playground.git
```

## Contributing

You also can run WordPress Playground locally as follows:
Clone the repo and build the projects:

```bash
git clone https://github.com/WordPress/wordpress-playground
cd wordpress-playground
git clone https://github.com/WordPress/playground-tools
cd playground-tools
npm install
npm run dev
npm run build
# or `npm run dev` to watch for changes
```

A browser should open and take you to your very own client-side WordPress at [http://127.0.0.1:5400/](http://127.0.0.1:5400/)!

Any changes you make to `.ts` files will be live-reloaded. Changes to `Dockerfile` require a full rebuild.

From here, the [documentation](https://wordpress.github.io/wordpress-playground/) will help you learn how WordPress Playground works and how to use it to build amazing things!

And here's a few more interesting CLI commands, which expect that you have `nx` installed globally:

```bash
# Build and run PHP.wasm CLI
nx start php-wasm-cli

# Build latest WordPress releases
nx recompile-wordpress:all playground-remote

# Recompile PHP 5.6 - 8.2 releases to .wasm for web
nx recompile-php:all php-wasm-web

# Recompile PHP 5.6 - 8.2 releases to .wasm for node
nx recompile-php:all php-wasm-node

# Builds the documentation site
nx build docs-site

# Builds the Playground Client npm package
nx build playground-client

# Bonus: Run PHP.wasm in your local CLI:
npx @php-wasm/cli -v
PHP=7.4 npx @php-wasm/cli -v
npx @php-wasm/cli phpcbf
```

## Backwards compatibility

This experimental software may break or change without a warning. Releasing a stable API is an important future milestone that will be reached once the codebase is mature enough.

## Prior art

WordPress Playground forked the original PHP to WebAssembly build published in https://github.com/oraoto/pib and modified later in https://github.com/seanmorris/php-wasm.

Another strong inspiration was the [Drupal in the browser demo](https://seanmorris.github.io/php-wasm/?autorun=0&persist=0&single-expression=0&code=%253C%253Fphp%250Aini_set%28%27session.save_path%27%252C%2520%27%252Fhome%252Fweb_user%27%29%253B%250A%250A%2524stdErr%2520%253D%2520fopen%28%27php%253A%252F%252Fstderr%27%252C%2520%27w%27%29%253B%250A%2524errors%2520%253D%2520%255B%255D%253B%250A%250Aregister_shutdown_function%28function%28%29%2520use%28%2524stdErr%252C%2520%2526%2524errors%29%257B%250A%2520%2520%2520%2520fwrite%28%2524stdErr%252C%2520json_encode%28%255B%27session_id%27%2520%253D%253E%2520session_id%28%29%255D%29%2520.%2520%2522%255Cn%2522%29%253B%250A%2520%2520%2520%2520fwrite%28%2524stdErr%252C%2520json_encode%28%255B%27headers%27%253D%253Eheaders_list%28%29%255D%29%2520.%2520%2522%255Cn%2522%29%253B%250A%2520%2520%2520%2520fwrite%28%2524stdErr%252C%2520json_encode%28%255B%27errors%27%2520%253D%253E%2520error_get_last%28%29%255D%29%2520.%2520%2522%255Cn%2522%29%253B%250A%257D%29%253B%250A%250Aset_error_handler%28function%28...%2524args%29%2520use%28%2524stdErr%252C%2520%2526%2524errors%29%257B%250A%2509fwrite%28%2524stdErr%252C%2520print_r%28%2524args%252C1%29%29%253B%250A%257D%29%253B%250A%250A%2524docroot%2520%253D%2520%27%252Fpreload%252Fdrupal-7.59%27%253B%250A%2524path%2520%2520%2520%2520%253D%2520%27%252F%27%253B%250A%2524script%2520%2520%253D%2520%27index.php%27%253B%250A%250A%2524_SERVER%255B%27REQUEST_URI%27%255D%2520%2520%2520%2520%2520%253D%2520%2524docroot%2520.%2520%2524path%253B%250A%2524_SERVER%255B%27REMOTE_ADDR%27%255D%2520%2520%2520%2520%2520%253D%2520%27127.0.0.1%27%253B%250A%2524_SERVER%255B%27SERVER_NAME%27%255D%2520%2520%2520%2520%2520%253D%2520%27localhost%27%253B%250A%2524_SERVER%255B%27SERVER_PORT%27%255D%2520%2520%2520%2520%2520%253D%25203333%253B%250A%2524_SERVER%255B%27REQUEST_METHOD%27%255D%2520%2520%253D%2520%27GET%27%253B%250A%2524_SERVER%255B%27SCRIPT_FILENAME%27%255D%2520%253D%2520%2524docroot%2520.%2520%27%252F%27%2520.%2520%2524script%253B%250A%2524_SERVER%255B%27SCRIPT_NAME%27%255D%2520%2520%2520%2520%2520%253D%2520%2524docroot%2520.%2520%27%252F%27%2520.%2520%2524script%253B%250A%2524_SERVER%255B%27PHP_SELF%27%255D%2520%2520%2520%2520%2520%2520%2520%2520%253D%2520%2524docroot%2520.%2520%27%252F%27%2520.%2520%2524script%253B%250A%250Achdir%28%2524docroot%29%253B%250A%250Aob_start%28%29%253B%250A%250Adefine%28%27DRUPAL_ROOT%27%252C%2520getcwd%28%29%29%253B%250A%250Arequire_once%2520DRUPAL_ROOT%2520.%2520%27%252Fincludes%252Fbootstrap.inc%27%253B%250Adrupal_bootstrap%28DRUPAL_BOOTSTRAP_FULL%29%253B%250A%250A%2524uid%2520%2520%2520%2520%2520%253D%25201%253B%250A%2524user%2520%2520%2520%2520%253D%2520user_load%28%2524uid%29%253B%250A%2524account%2520%253D%2520array%28%27uid%27%2520%253D%253E%2520%2524user-%253Euid%29%253B%250Auser_login_submit%28array%28%29%252C%2520%2524account%29%253B%250A%250A%2524itemPath%2520%253D%2520%2524path%253B%250A%2524itemPath%2520%253D%2520preg_replace%28%27%252F%255E%255C%255C%252Fpreload%252F%27%252C%2520%27%27%252C%2520%2524itemPath%29%253B%250A%2524itemPath%2520%253D%2520preg_replace%28%27%252F%255E%255C%255C%252Fdrupal-7.59%252F%27%252C%2520%27%27%252C%2520%2524itemPath%29%253B%250A%2524itemPath%2520%253D%2520preg_replace%28%27%252F%255E%255C%252F%252F%27%252C%2520%27%27%252C%2520%2524itemPath%29%253B%250A%250Aif%28%2524itemPath%29%250A%257B%250A%2520%2520%2520%2520%250A%2520%2520%2520%2520%2524router_item%2520%253D%2520menu_get_item%28%2524itemPath%29%253B%250A%2520%2520%2520%2520%2524router_item%255B%27access_callback%27%255D%2520%253D%2520true%253B%250A%2520%2520%2520%2520%2524router_item%255B%27access%27%255D%2520%253D%2520true%253B%250A%2520%2520%2520%2520%250A%2520%2520%2520%2520if%2520%28%2524router_item%255B%27include_file%27%255D%29%2520%257B%250A%2520%2520%2520%2520%2520%2520require_once%2520DRUPAL_ROOT%2520.%2520%27%252F%27%2520.%2520%2524router_item%255B%27include_file%27%255D%253B%250A%2520%2520%2520%2520%257D%250A%2520%2520%2520%2520%250A%2520%2520%2520%2520%2524page_callback_result%2520%253D%2520call_user_func_array%28%2524router_item%255B%27page_callback%27%255D%252C%2520unserialize%28%2524router_item%255B%27page_arguments%27%255D%29%29%253B%250A%2520%2520%2520%2520%250A%2520%2520%2520%2520drupal_deliver_page%28%2524page_callback_result%29%253B%250A%257D%250Aelse%250A%257B%250A%2520%2520%2520%2520menu_execute_active_handler%28%29%253B%250A%257D&render-as=html) which proved you can run non-trivial PHP software in the browser.

A worthy mention is Wasm Labs’s closed-source [WordPress in the browser](https://wordpress.wasmlabs.dev/) shared before this project was first published. There is no public repository available, but their [technical overview](https://wasmlabs.dev/articles/wordpress-in-the-browser/) gives a breakdown of the technical decisions that project took. WordPress Playground draws inspiration from the same PHP in the browser projects and makes similar technical choices.

## Using WP-NOW for local environment

WordPress Playground comes with `wp-now`. `wp-now` is a Command Line Interface (CLI) tool designed to streamline the process of setting up a local WordPress environment by using only Node.js. If you are looking to set up `wp-now` specifically, you can follow [this README.md](/packages/wp-now/README.md).
You'll find the built assets in the dist directory. You can make changes, run the VS Code extension or install the interactive code plugin, and test them.
