A simple scalable server built on top of Headless Chrome. The API is built with Protocol Buffers and Twirp.

This is an experimental project in early phase.

Goals:

1. Server should be scalable Docker image with HTTP server listening on port :80
2. The Docker image is ideally built on top of some official and stable Headless Chrome image (FROM base/image:version)
3. Clients should be automatically generated via Protobuf file + Twirp RPC framework
4. Built-in & configurable request throttling
5. Generate functional client in Go, JS (Typescript) and maybe other languages

Base image candidates:

• https://hub.docker.com/r/justinribeiro/chrome-headless/
• https://hub.docker.com/r/selenoid/chrome/
• https://hub.docker.com/r/browserless/chrome/
• https://github.com/GoogleChrome/puppeteer/blob/fae441cd42fc410115ce9cec40563e21260db9b6/docs/troubleshooting.md#running-puppeteer-in-docker
• anything else?

Usage

1. So far, this project works with Chrome Canary /Applications/Google\ Chrome\ Canary.app/Contents/MacOS/Google\ Chrome\ Canary --headless --remote-debugging-port=9222 --no-gpu
2. However, it doesn't work with docker run --name=chrome -p 9222:9222 --cap-add=SYS_ADMIN justinribeiro/chrome-headless --headless --remote-debugging-port=9222 --disable-gpu, which is strange.. trying to figure that out

Development

1. Install tools to work with Protocol Buffers and Twirp.
