Oj (Optimized JSON) is a fast JSON parser and object marshaller implemented as a C extension for Ruby. It serves as a drop-in replacement for the standard json gem and Rails/ActiveSupport serialization, with multiple compatibility modes.
Use cases
- parse json fast in ruby
- serialize ruby objects to json
- drop-in replacement for ruby json gem
- speed up rails json serialization
- marshal ruby objects to json strings
- benchmark json parsing in ruby
When to choose
- you need faster JSON encoding/decoding than the built-in json gem
- you want json gem or Rails/ActiveSystem compatibility without changing code
- you need object marshalling to JSON in Ruby
When to avoid
- you are not working in Ruby
- you need a pure-Ruby dependency without native C extensions
