**The companion** `webwords git repo <https://github.com/russellballestrini/webwords>`_ **lives here.**
This project shows how to code the same minimal web app called ``webwords`` in as many different programming languages as possible.
It also provides guides for building and running ``webwords`` as a docker images.

The application always returns an ``HTTP 200`` response with the string ``true`` or ``false`` depending on if the keyword is found in the ``target`` web page body.
Once you have the application running inside docker, run this command to get the exposed port:
.. code-block:: bash
docker ps
To see if a ``keyword`` exists on a ``target`` web page, put the follwing in a browser:
For example, to see if the word ``potato`` exists on `Remarkbox <https://www.remarkbox.com>`_, put the follwing in a browser:
.. code-block:: txt
http://127.0.0.1:32779/?keyword=potato&target=https://www.remarkbox.com
In this example we check if the keyword ``potato`` is on the web page https://www.remarkbox.com
Spoiler:
it is
potato does exist on Remarkbox, : )
Note:
You will need to replace the port of ``32779`` with the port from the ``docker ps`` output.

I think the spec of webwords is small enough for people new to any language to digest but complete in that it does something useful and demonstrates two common tasks: running an HTTP server and using an HTTP client.
Also, I needed a way to verify if a user had possession of a domain name for the `comment service <https://www.remarkbox.com>`_ I'm building called Remarkbox. I decided to make this verification program a micro service, first with Python and later with Go. The result was webwords.

Shortly after during a hackathon I used webwords to learn how to build Docker images for various languages and formalize the idea into a single project.
