Guild Wars 2 Price Check

Live price checks for Guild Wars 2 trading

Synopsis

This is the code for gw2pc.com, a website which uses the Guild Wars 2 API to calculate prices for items that are commonly traded between players. It is created and hosted by Cirdan for use on the Overflow Discord server, but is free to use by anyone who needs it.

Contributing

Contributions are welcome. The website is written using the Django web framework, with Material used for styling. Use the rebuild_venv.sh script to install the Python dependencies, and npm install to populate node_modules with the required CSS and JS dependencies. You can now run manage.py runserver to start a local webserver. You may need to modify gw2pc/local_settings.py, in particular, the ALLOWED_HOSTS variable.

The live website is hosted using Zappa on Amazon AWS serverless. Essentially, a Cloudfront instance handles caching and serving static files from an S3 bucket, while dynamic webpages are provided by calling a Lambda function. This is all configured by calling something like zappa deploy prod, provided that you have AWS credentials, and the scripts used to update these are present in the repository.

Note that it is currently required to call sass manually as shown in the update scripts, Django's sass_processor does not work due to some unsupported fork of the sass binary which does not support modern features. If you update CSS in static/css/style.scss, you will need to call the command shown in that update script in order to update the CSS file.

TODO

• The current views.py discourages code reuse. It made sense while just outlining the project, but now that we have a few pages, they should be refactored and converted to use class-based views.
• The current table rendering code, in which the table layout is done in an .html include and the individual cells are rendered using a series of templatetages, is quite ugly. Tables should probably just be a Class with a method .render().
• The format_gold_* set of functions is a bit silly, and deciding whether or not to use icons and whether or not to show the coppers should probably be handled through arguments.
• Should we actually use gold/silver/copper icons?
• The HTML pages also, to an extent, discourage code reuse. Is there anything that can be factored out?
