This library implements the ChromeDevTools DOMPath functionality in Playwright.
This means that you can retrieve the CSS selector or the XPath of any element you select in your Playwright code.
🐍 _Python version here: [https://github.com/alexferrari88/playwright-dompath-py](https://github.com/alexferrari88/playwright-dompath-py)_
## Installation 📦
Install with npm
```bash
npm install playwright-dompath
```
## API Reference 📚
#### cssPath
```typescript
cssPath: (elHandle: Playwright.ElementHandle | Playwright.Locator, optimized?: boolean) => Promise
```
#### xPath
```typescript
xPath: (elHandle: Playwright.ElementHandle | Playwright.Locator, optimized?: boolean) => Promise
```
## Usage 🔧
Just import the `cssPath` or `xPath` from this module:
```typescript
import { cssPath, xPath } from "playwright-dompath";
```
Then use either function by passing it the element you previously selected (as ElementHandle or Locator):
```typescript
const searchBar = await page.$('input[name="q"]');
console.log("CSS Path:", await cssPath(searchBar));
console.log("XPath:", await xPath(searchBar));
```
_Since these functions return a promise, make sure to `await` the call (of course, you can also use the `.then` syntax instead. You do you.)_
## Full Example 🎁
```typescript
import { chromium } from "playwright";
import { cssPath, xPath } from "playwright-dompath";
const url = "https://google.com";
const browser = await chromium.launch();
const context = await browser.newContext();
const page = await context.newPage();
await page.goto(url);
const searchBar = await page.$('input[name="q"]');
console.log("CSS Path:", await cssPath(searchBar));
console.log("XPath:", await xPath(searchBar));
}
await browser.close();
};
```
Which will output (class names may vary for you):
```bash
CSS Path: body > div.L3eUgb > div.o3j99.ikrT4e.om7nvf > form > div:nth-child(1) > div.A8SBwf > div.RNNXgb > div > div.a4bIc > input
XPath: /html/body/div[1]/div[3]/form/div[1]/div[1]/div[1]/div/div[2]/input
```
