The problem

Building recent searches experience can be trickier than you think (expiry of queries, ranking of recent queries, handling storage etc...)

Solution

recent-searches module helps you build that experience without having to focus on the edge cases and technical details. If available, uses localStorage to store suggestions cross sessions and in the rare cases where it might not be available uses a fallback memory storage, thus loosing it's cross session functionality.

The module handles:

  • Searching and retrieving recent searches
  • Ranking of searches and decaying their popularity (with different ranking options)
  • Saving and expiring of searches through LocalStorage or MemoryStorage
  • LocalStorage feature detection (with fallback to MemoryStorage)
  • Safe LocalStorage usage (feature detection, limiting storage)
