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
