> See [`this article`](https://www.howtogeek.com/202825/what%E2%80%99s-the-difference-between-chromium-and-chrome/) for a description of the differences between Chromium and Chrome. [`This article`](https://chromium.googlesource.com/chromium/src/+/lkgr/docs/chromium_browser_vs_google_chrome.md) describes some differences for Linux users.
#### chromiumPlaywright.launchServer([options])
- `options` <[Object]> Set of configurable options to set on the browser. Can have the following fields:
- `headless` <[boolean]> Whether to run browser in [headless mode](https://developers.google.com/web/updates/2017/04/headless-chrome). Defaults to `true` unless the `devtools` option is `true`.
- `executablePath` <[string]> Path to a Chromium or Chrome executable to run instead of the bundled Chromium. If `executablePath` is a relative path, then it is resolved relative to [current working directory](https://nodejs.org/api/process.html#process_process_cwd). **BEWARE**: Playwright is only [guaranteed to work](https://github.com/Microsoft/playwright/#q-why-doesnt-playwright-vxxx-work-with-chromium-vyyy) with the bundled Chromium, use at your own risk.
- `slowMo` <[number]> Slows down Playwright operations by the specified amount of milliseconds. Useful so that you can see what is going on.
- `args` <[Array]<[string]>> Additional arguments to pass to the browser instance. The list of Chromium flags can be found [here](http://peter.sh/experiments/chromium-command-line-switches/).
- `ignoreDefaultArgs` <[boolean]|[Array]<[string]>> If `true`, then do not use [`playwright.defaultArgs()`](#playwrightdefaultargsoptions). If an array is given, then filter out the given default arguments. Dangerous option; use with care. Defaults to `false`.
- `handleSIGINT` <[boolean]> Close the browser process on Ctrl-C. Defaults to `true`.
- `handleSIGTERM` <[boolean]> Close the browser process on SIGTERM. Defaults to `true`.
- `handleSIGHUP` <[boolean]> Close the browser process on SIGHUP. Defaults to `true`.
- `timeout` <[number]> Maximum time in milliseconds to wait for the browser instance to start. Defaults to `30000` (30 seconds). Pass `0` to disable timeout.
- `dumpio` <[boolean]> Whether to pipe the browser process stdout and stderr into `process.stdout` and `process.stderr`. Defaults to `false`.
- `userDataDir` <[string]> Path to a [User Data Directory](https://chromium.googlesource.com/chromium/src/+/master/docs/user_data_dir.md).
- `env` <[Object]> Specify environment variables that will be visible to the browser. Defaults to `process.env`.
- `devtools` <[boolean]> Whether to auto-open a DevTools panel for each tab. If this option is `true`, the `headless` option will be set `false`.
- `pipe` <[boolean]> Connects to the browser over a pipe instead of a WebSocket. Defaults to `false`.
- returns: <[Promise]<[BrowserServer]>> Promise which resolves to browser server instance.

- `'raf'` - to constantly execute `pageFunction` in `requestAnimationFrame` callback. This is the tightest polling mode which is suitable to observe styling changes.
- `'mutation'` - to execute `pageFunction` on every DOM mutation.
- `timeout` <[number]> maximum time to wait for in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default value can be changed by using the [page.setDefaultTimeout(timeout)](#pagesetdefaulttimeouttimeout) method.

- returns: <[Promise]<[JSHandle]>> Promise which resolves to a JSHandle of the success value
This method runs `document.querySelector` within the page and passes it as the first argument to `pageFunction`. If there's no element matching `selector`, the method throws an error.
If `pageFunction` returns a [Promise], then `page.$wait` would wait for the promise to resolve and return its value. The function
is being called on the element periodically until either timeout expires or the function returns the truthy value.

- `'mutation'` - to execute `pageFunction` on every DOM mutation.
- `timeout` <[number]> maximum time to wait for in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default value can be changed by using the [page.setDefaultTimeout(timeout)](#pagesetdefaulttimeouttimeout) method.
