Puppeteer Lambda

Module for using Headless-Chrome by Puppeteer on AWS Lambda.
Idea from Puppeteer Lambda Starter Kit , thanks Taiki Sakamoto

How to use

npm install puppeteer-lambda or yarn add puppeteer-lambda

(async () => {
    const puppeteerLambda = require('puppeteer-lambda');
    const browser = await puppeteerLambda.getBrowser({
    headless: true
    });
    const page = await browser.newPage();
    await page.goto('https://example.com');
    await page.screenshot({path: 'example.png'});

    await browser.close(); 
})();

Packaging & Deploy

Lambda's memory needs to be set to at least 384 MB, but the more memory, the better the performance of any operations.

512MB -> goto(youtube): 6.481s
1536MB -> goto(youtube): 2.154s

You should also set a environment variable in lambda:

CUSTOM_CHROME = true

NOTE: This project uses puppeteer so don't forget to set PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true before run npm install or yarn when you prepare the package for lambda.

1.chrome in package (recommended)

run CUSTOM_CHROME=true npm install puppeteer-lambda or CUSTOM_CHROME=true yarn add puppeteer-lambda ,then deploy the package, and set the following env variables in lambda.

  • CUSTOM_CHROME(required): tell the progress to use the custom chrome(locale version or download from s3 automatically)

PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true CUSTOM_CHROME=true yarn add puppeteer-lambda
then please check the node_modules/puppeteer-lambda

2.chrome NOT in package

Due to the large size of Chrome, it may exceed the Lambda package size limit (50MB) depending on the other module to include. In that case, put Chrome Binary in S3 and download it at container startup so startup time will be longer.
You can also download the specific version of chrome from Serverless Chrome

Run npm install puppeteer-lambda or yarn add puppeteer-lambda, deploy the package , and set following env valiables on Lambda.

  • CHROME_BUCKET(required): S3 bucket where Chrome is put
  • CHROME_KEY(optional): S3 key. default: headless_shell.tar.gz
