```javascript
{
  "dependencies": {
    "playwright": "^1.x.x"
  }
}

// After install, replace references in code:
// require('playwright') -> require('rebrowser-playwright')
```

### Integrate Rebrowser Puppeteer Patches (direct replacement)

Source: https://github.com/rebrowser/rebrowser-patches/blob/main/README.md

This snippet shows how to directly replace Puppeteer packages with rebrowser-puppeteer packages in package.json. It requires updating package names, running an install, and potentially refactoring code that references the original package names.

```javascript
{
  "dependencies": {
    "puppeteer": "^23.3.1",
    "puppeteer-core": "^23.3.1"
  }
}

// After install, replace references in code:
// require('puppeteer') -> require('rebrowser-puppeteer')
// require('puppeteer-core') -> require('rebrowser-puppeteer-core')
```

--------------------------------

### Integrating with puppeteer-extra

Source: https://github.com/rebrowser/rebrowser-patches/blob/main/README.md

Demonstrates how to integrate rebrowser-puppeteer with the puppeteer-extra library using the `addExtra` method.

```javascript
// before
import puppeteer from 'puppeteer-extra'

// after
import { addExtra } from 'puppeteer-extra'
import rebrowserPuppeteer from 'rebrowser-puppeteer-core'
const puppeteer = addExtra(rebrowserPuppeteer)
```

### Setting Runtime Fix Mode via Command Line

Source: https://github.com/rebrowser/rebrowser-patches/blob/main/README.md

Illustrates setting the Runtime.Enable leak fix mode when executing a Node.js application from the command line.

```shell
REBROWSER_PATCHES_RUNTIME_FIX_MODE=alwaysIsolated node app.js
```

--------------------------------

### Runtime.Enable Leak Fix Modes

Source: https://github.com/rebrowser/rebrowser-patches/blob/main/README.md

Configuration options for fixing the Runtime.Enable leak. These environment variables allow switching between different patching strategies or disabling the fix entirely.

```shell
REBROWSER_PATCHES_RUNTIME_FIX_MODE=addBinding
REBROWSER_PATCHES_RUNTIME_FIX_MODE=alwaysIsolated
REBROWSER_PATCHES_RUNTIME_FIX_MODE=enableDisable
REBROWSER_PATCHES_RUNTIME_FIX_MODE=0
```

--------------------------------

### Access Browser CDP Connection (JavaScript)

Source: https://github.com/rebrowser/rebrowser-patches/blob/main/README.md

This patch adds a `_connection()` method to the Browser class, allowing direct access to the browser's CDP session. This is useful for implementing custom CDP commands or listening to browser-level events.

```javascript
browser._connection().on('Rebrowser.addRunEvent', (params) => { ... })
```

--------------------------------

### Setting Runtime Fix Mode in Code

Source: https://github.com/rebrowser/rebrowser-patches/blob/main/README.md

Demonstrates how to programmatically set the Runtime.Enable leak fix mode within a Node.js application using environment variables.

```javascript
process.env.REBROWSER_PATCHES_RUNTIME_FIX_MODE = "alwaysIsolated"
```

--------------------------------

### Runtime.Enable Leak Debug Mode

Source: https://github.com/rebrowser/rebrowser-patches/blob/main/README.md

REBROWSER_PATCHES_DEBUG=1
```

--------------------------------

### Integrate Rebrowser Playwright Patches (npm alias)

Source: https://github.com/rebrowser/rebrowser-patches/blob/main/README.md

This snippet illustrates how to use npm aliases in package.json to integrate rebrowser-playwright packages for Node.js. This method allows using the patched Playwright without modifying existing automation scripts.

```javascript
{
  "dependencies": {
    "playwright": "npm:rebrowser-playwright@^1.x.x"
  }
}

// Then run:
npm install
```

--------------------------------

### Change Default Utility World Name (Shell)

Source: https://github.com/rebrowser/rebrowser-patches/blob/main/README.md

Allows customization of the default utility world name used by Puppeteer. The name can be changed via the `REBROWSER_PATCHES_UTILITY_WORLD_NAME` environment variable. Setting it to '0' disables the patch.

```shell
REBROWSER_PATCHES_UTILITY_WORLD_NAME=customUtilityWorld
# use 0 to completely disable this patch
REBROWSER_PATCHES_UTILITY_WORLD_NAME=0
```

--------------------------------

### Changing sourceURL to Generic Script Name

Source: https://github.com/rebrowser/rebrowser-patches/blob/main/README.md

Modifies the default Puppeteer `sourceURL` comment added to evaluated scripts. This patch changes it from `//# sourceURL=pptr:...` to a generic name like `//# sourceURL=app.js` to avoid detection.

```shell
# use any generic filename
REBROWSER_PATCHES_SOURCE_URL=jquery.min.js
# use 0 to completely disable this patch
REBROWSER_PATCHES_SOURCE_URL=0
```

--------------------------------

### Playwright Runtime Enable Leak Fix

Source: https://github.com/rebrowser/rebrowser-patches/blob/main/README.md

Addresses a leak in Playwright's `Runtime.enable` functionality, specifically related to `addBinding` and `alwaysIsolated` modes. Disabling this fix via `REBROWSER_PATCHES_RUNTIME_FIX_MODE=0` is recommended for debugging with `page.pause()`.

```APIDOC
Playwright Patches:

Runtime.enable leak fix:
  - Addresses issues with `addBinding` and `alwaysIsolated` modes.
  - Can be disabled for debugging `page.pause()` using `REBROWSER_PATCHES_RUNTIME_FIX_MODE=0`.
  - Currently only supports Chrome. For WebKit or Firefox, please open an issue.

Utility World Name Customization:
  - Allows changing the utility world name via `REBROWSER_PATCHES_UTILITY_WORLD_NAME` environment variable.
  - This setting is applied at module import time and cannot be changed dynamically.
