diffson VS circe

But OPs two samples will not be equal with the default LCS algo as the array positions matter. If you only need to check equality, the simple diff should work for you.

Using Circe so I define some classes that contain my custom Encoder[BusinessObject] in a file and I use that whenever I want to save/store a record, or handle a web request or respose. I also represent my mongo queries as JSON objects that I can freely build then pass to the driver.

Circe adopters should be using Scala https://github.com/circe/circe

If you look at Circe's github repo you will see a very large list of very recognizable companies, that should give you some idea. Circe isn't the ONLY Json parsing library, but it is probably the most popular, so - should give you a rough idea of the types and variety of companies using Scala.

Has the worst error messages I've ever seen for a parser. "Attempt to decode value on failed cursor" is not helpful when all you have is missing fields. Has been an issue for 5 years.

Circe tries to drop Scala 2.12 support in retaliation for not enough users paying them.

PR for the same functionality in Scala3: https://github.com/circe/circe/pull/1800

Otherwise I tend to just use ZIO-JSON or Circe both of which have been updated for Scala 3.

I've updated results of benchmarks of 12 JSON parsers for Scala: - AVSystem's scala-commons - Borer - Circe - DSL-JSON - Jackson - jsoniter-scala - Play-JSON, - play-json-jsoniter - Spray-JSON - uPickle - weePickle - zio-json
