Roothmarket is a comparison shopping service app for products from multiple online stores. This data is automatically, periodically gathered from the shopping feed of different stores.

This was developed using a PHP framework and SQL as the database.

The main features are:

• Manage stores and their feeds. Map the feed categories to custom categories.
• Periodically process feeds to update the product listing related to different stores.
• Ability to search and filter products based on stores, categories, prices, and brands.
• Auto-set language and currency based on the selected country and list the appropriate products.
• Display product details and available variants. 
• Compare the price of different variants of the same product on a single page.

Technical information:

• The application is developed using the CodeIgniter PHP framework and SQL as the database.
• Elasticsearch is employed to index the feed-data, perform an advanced and efficient search on the large data-set. It also enables text operations like autocompletion, spelling variations, and typo handling. 
• Redis is employed as an in-memory database for caching frequently used data.
• The front end of the application is built using Vue.js and Twitter Bootstrap to provide a snappy user experience.

Future plans

• Implement outgoing feed and parallel tracking for listing feed data on Google shopping.
• Further, optimize the feed parser to ensure scalability.
• Employ Machine learning (ML) for automated and effective mapping of feed categories to custom categories.
