The aeson package

[Tags: bsd3, library]

A JSON parsing and generation library optimized for ease of use and high performance.

Parsing performance with GHC 6.12.3 on a late 2010 MacBook Pro (2.66GHz Core i7), for mostly-English tweets from Twitter's JSON search API:

Handling heavily-escaped text is a little more work. Here is parsing performance with Japanese tweets, where much of the text is entirely Unicode-escaped:

Encoding performance on the same machine and data:

With GHC 7.0.2, the story is mixed: parsing is 20-40% slower than GHC 6.12.3, while encoding performance ranges from about the same to twice as fast (on numeric data).

(A note on naming: in Greek mythology, Aeson was the father of Jason.)
