Shopping for certain items online can be time-consuming, especially if you are a collector or looking for something specific, checking multiple sites every day. Especially Japanese sites can be a pain to navigate. The Postal Service page serves as a frontend for a server that either runs the postalservice Python package on request, or displays results from an index where a web crawler continously collects listings using the postalservice package.
This way all of the interesting listings can be viewed in one place with a clear UI, near instant search, and recommendations for similar images (in progress).
The tech stack for this project is React and Algolia index for fast searching and filtering. The site is deployed on Vercel and the scraper is running on a virtual machine from Oracle.
