longurl

Expand Short ‘URLs’

Description

Tools are provided to expand vectors of short URLs into long ‘URLs’. No ‘API’ services are used, which may mean that this operates more slowly than ‘API’ services do (since they usually cache results of expansions that every user of the service requests). You can setup your own caching layer with the ‘memoise’ package if you wish to have a speedup during single sessions or add larger dependencies, such as ‘Redis’, to gain a longer-term performance boost at the expense of added complexity.

What’s Inside The Tin

The following functions are implemented:

• expand_urls: Expand a vector of (short) URLs using
