Overview

It's design to make SEO for single page application easier, so that you don't have to use Server-side rendering tricks.

It acts like a transparent http proxy by default, it only actives when the client looks like a web crawler, such as Googlebot, Baiduspider, etc.

Installation

You can simplify use bartender as the gateway in front of your web server:

docker run -p 3000:3000 ghcr.io/go-rod/bartender ./serve -p :3000 -t http://your-web-server:8080

A common data flow looks like this:

graph TD;
  C[Client]-->B;

  subgraph B[Bartender]
    J{Is web crawler?};
    J-->|Yes|R[Render with headless browser];
    J-->|No|D[Transparent proxy];
  end

  R-->H[Your web server];
  D-->H;

Loading

If you want the best performance, you can install bartender behind a gateway like nginx, configure the gateway to proxy the request to bartender when the client looks like a web crawler.

A common way to detect web crawler: link.

A common data flow looks like this:

graph TD;
  C[Client]-->T[Gateway];
  T-->J{Is web crawler?};
  J-->|Yes|B[Bartender];
  J-->|No|H[Your web server];
  B-->H;
