Haxl is a Haskell library that simplifies access to remote data sources such as databases and web services. It automatically batches requests, fetches from multiple sources concurrently, and caches/memoizes results.

Use cases

  • batch multiple requests to the same data source
  • solve the N+1 selects problem in SQL queries
  • fetch data from multiple APIs concurrently
  • cache and memoize remote data access
  • write clean declarative data-fetching code in Haskell

When to choose

  • you write Haskell and need efficient concurrent access to remote data sources
  • you want automatic request batching without manual optimization
  • you need to eliminate N+1 query patterns in your data layer

When to avoid

  • your project is not in Haskell
  • you need a general-purpose HTTP client rather than a data-access framework
  • you want a ready-made data source with no custom integration work
