# Grender - Web Page Renderer

❗ **This project is in a very early stage of development.** ❗

Grender is a web rendering service written in Go that leverages a headless Chrome browser to render and cache web pages. The application supports various backends, including AWS S3 and local file systems, for storing cached content.

## Configuration

The server is configured using a `config.yaml` file. Here's an example:

```yaml

version: v1

# There are three modes: "rendering" and "recaching"

modes: 

  rendering: true

  recaching: true

renderingConfig:

  pageWaitTime: 10

  pageWaitCondition: '(function() { return window.prerenderReady === true })()'

  # requestHeaders:

  #   - name: "X-Grender-Request"

  #     value: "1"

server:

  port: "8080"

  responseHeaders:

    - name: "X-Prerender"

      value: "1"

backend:

  fileSystem:

    baseDir: "./tmp"

  # s3:

  #   bucketName: "grender.io"

  #   region: "ap-southeast-2"

invalidate:

  amqp:

    uri: "amqp://user:password@localhost:5672/"

    timeout: 10

    queue: "invalidate" 

```

## Running the Server

To run the server, use the following command:

```bash

go run main.go

```

Make sure to have your config.yaml file in the same directory where you run this command.

## Project Structure

The main components of the project are organized into packages:

- **pilot:** Contains the main Grender application files, including configuration, rendering logic, and server setup.

- **backend:** Provides interfaces and implementations for different backends, such as S3 and file systems.

- **render:** Implements the rendering logic using a headless Chrome browser.

## Dependencies

Grender relies on third-party packages for AWS S3 integration, YAML parsing, and headless Chrome browser automation.
