# Netlify functions + Headless Chrome    

> Run headless chrome in netlify lambda functions

## How

Add a [Netlify function](https://www.netlify.com/products/functions/) with the following code!

```js

const chromium = require('chrome-aws-lambda')

const puppeteer = require('puppeteer-core')

exports.handler = async (event, context, callback) => {

  let theTitle = null

  let browser = null

  console.log('spawning chrome headless')

  try {

    const executablePath = await chromium.executablePath

    // setup

    browser = await puppeteer.launch({

      args: chromium.args,

      executablePath: executablePath,

      headless: chromium.headless,

    })

    // Do stuff with headless chrome

    const page = await browser.newPage()

    const targetUrl = 'https://davidwells.io'

    // Goto page and then do stuff

    await page.goto(targetUrl, {

      waitUntil: ["domcontentloaded", "networkidle0"]

    })

    await page.waitForSelector('#phenomic')

    theTitle = await page.title();

    console.log('done on page', theTitle)

  } catch (error) {

    console.log('error', error)

    return callback(null, {

      statusCode: 500,

      body: JSON.stringify({

        error: error

      })

    })

  } finally {

    // close browser

    if (browser !== null) {

      await browser.close()

    }

  }

  return callback(null, {

    statusCode: 200,

    body: JSON.stringify({

      title: theTitle,

    })

  })

}

```
