Helper module for Nginx haskell module

Latest on Hackage:

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow to host generated Haddocks.

Helper module for Nginx haskell module


  • Lazy bytestrings contents are no longer copied when passed back to nginx. Instead, they are passed directly along with a StablePtr to original bytestrings. This must improve performance and lower memory consumption for content handlers with large outputs.

  • All synchronous variable and content handlers were made exception safe.
  • Bugfix: evaluate results of IO handlers strictly to make sure that all exceptions will be caught.

  • Bugfix: keep calling fdWriteBuf until it writes complete buffer.

  • All asynchronous handlers can now report events via eventfd channels.
  • New dependency on package binary (>=

  • Stricter constraints for packages base (>= 4.8 && < 5) and template-haskell (>=

  • Versioning security: get number of required version parts from C code.

  • Added versioning support to test for compatibility in C code.

  • Added an asynchronous client request body handler exported with ngxExportAsyncOnReqBody for using in a new Nginx directive haskellrunasynconrequest_body.

  • Added signatures for type-checkers and exporters to prevent warnings when reifying in a user code with -Wmissing-signatures or -Wall enabled.

  • Added a synchronous handler in IO Monad exported with ngxExportIOYY.
