Purpose

This utility generates opengraph images.

How it works

the short version

Make an HTTP request to the endpoint, pass it some parameters, and it will return an image.

The long version

This is a webserver process

1. HTTP request received
2. Validate params
3. Generate an HTML page from a tempalte + parameters
4. Render that HTML page with a headless web browser
5. Screenshot the page using headless browser
6. Save that image out to a jpg
7. Return the image

Using the service

Docker is probably the best way to kick the tires.

docker run --name ogaas --rm -p 8000:8000 -v $PWD/templates:/templates ogaas

That will get you going on port 8000

Creating your own templates

Everything should live in your template file (css and HTML). See the examples to see how it can work for you.
