Serverless Chrome contains everything you need to get started running headless Chrome on AWS Lambda (possibly Azure and GCP Functions soon).

The aim of this project is to provide the scaffolding for using Headless Chrome during a serverless function invocation. Serverless Chrome takes care of building and bundling the Chrome binaries and making sure Chrome is running when your serverless function executes. In addition, this project also provides a few example services for common patterns (e.g. taking a screenshot of a page, printing to PDF, some scraping, etc.)

Why? Because it's neat. It also opens up interesting possibilities for using the Chrome DevTools Protocol (and tools like Chromeless or Puppeteer) in serverless architectures and doing testing/CI, web-scraping, pre-rendering, etc.

"Bla bla bla! I just want to start coding!" No problem:

Using AWS Lambda, the quickest way to get started is with the Serverless-framework CLI.

First, install serverless globally (npm install -g serverless) and then:

serverless create -u https://github.com/adieuadieu/serverless-chrome/tree/master/examples/serverless-framework/aws

Then, you must configure your AWS credentials either by defining AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environmental variables, or using an AWS profile. You can read more about this on the Serverless Credentials Guide.

In short, either:

export AWS_PROFILE=<your-profile-name>

or

export AWS_ACCESS_KEY_ID=<your-key-here>
export AWS_SECRET_ACCESS_KEY=<your-secret-key-here>

Then, to deploy the service and all of its functions:

npm run deploy

Further details are available in the Serverless Lambda example.

This project contains:

• @serverless-chrome/lambda NPM package
  A standalone module for AWS Lambda which bundles and launches Headless Chrome with support for local development. For use with—but not limited to—tools like Apex, Claudia.js, SAM Local, or Serverless.
• serverless-plugin-chrome NPM package
  A plugin for Serverless-framework services which takes care of everything for you. You just write the code to drive Chrome.
• Example functions
  • Serverless-framework AWS Lambda Node.js functions using serverless-plugin-chrome
• Build Automation & CI/CD
  Build and release tooling shell scripts and Dockerfile for automating the build/release of headless Chrome for serverless environments (AWS Lambda).

A collection of example functions for different providers and frameworks.

• Serverless-framework Some simple functions for the Serverless-framework on AWS Lambda. It includes the following example functions:

  • Print to PDF
  • Capture Screenshot
  • Page-load Request Logger

• Automated, regularly prebuilt binaries can be found on the Releases page 😎
• adieuadieu/headless-chromium-for-aws-lambda Docker image
• Documentation on building your own binaries
• Medium article on how to do build from scratch. This was the origin of this project.

Test with npm test. Each package also contains it's own integration tests which can be run with npm run test:integration.
