requests-scala VS jackson-module-scala

There's the Li Haoyi's ecosystem of tools and libraries that's fun to hack on, has a low entry-bar (with a design philosophy of using the least complex abstractions for the job), and has few libs like requests and cask that may appeal to those liking some python minimalism. That's not the fastest way to learn hardcore FP, that's not the worst either.

Another thing that caught my attention is the choice for HTTP client. If the authors wanted to go with the simplest thing, they could have picked requests-scala (from the com-lihaoyi family of libraries). If they wanted to go with full blown Scala FP, they could have chosen http4s client (Ember). Sttp awkwardly sits in the middle being neither.

Finally, to give you an example of how simple Scala can be when you get rid of all the fancy stuff, take a look at the examples in Li Haoyi's requests-scala library, a port of the excellent requests Python library. I challenge anyone to call that code complex.

http4s (either with Blaze or Ember) is great, but you may need to think a bit about what you're doing. Maybe https://github.com/com-lihaoyi/requests-scala will be the best choice for your particular situation?

The other comment is asking the right questions. But also how is it failing? Do you have an error message? Is JsonUtil part of Jackson? Do you need to be using https://github.com/fasterxml/jackson-module-scala with an object mapper?

As a workaround you can turn on ignoring of unknown properties on the level of object mapper instance like here, but beware in case your system accepts an untrusted input because it turns on DoS vulnerability.

The simplest JSON parsing library is Jackson.

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
