Implementation

Dub is built as a standard Next.js application with Middleware to handle multi-tenancy, inspired by the Vercel Platforms Starter Kit.

Redis is used as the database for storing links and analytics data, which works well for key-value data types. Redis also has the Sorted Set data type, which is perfect for storing & retrieving time-series analytics data. Here's the full schema:

  • {hostname}:links – hashmap of all links for a given hostname (e.g. dub.sh:links)
  • {hostname}:links:timestamps – sorted set of all link timestamps for a given hostname (e.g. dub.sh:links:timestamps)
  • {hostname}:clicks:{linkId} – sorted set of all clicks for a given link (e.g. dub.sh:clicks:github)
  • {hostname}:root:clicks – sorted set of all root link clicks for a given hostname (e.g. dub.sh:root:clicks)
