FastJsonparser is ruby wrapper for simdjson which is written in c++.
JSON is de facto standard for exchanging data between web server and browser.
If your application is parsing large JSON data then you must consider optimising it for better performance.
I came across Simdjson which claims to parse gigabytes of JSON per second, It also claims to be over 2.5x faster than other production-grade JSON parsers. I thought this is fantastic why I am not using it.
I looked for the ways to use it and came across simdjson_ruby gem . It is wrapper for simdjson c++ library but unfortunately it was not working.
I started fixing it but got stuck in configurations then I thought why not create a new gem and import all code which I need from this gem, thus FastJsonparser was born.
To verify simdjson claim that it is really fast, I did benchmarking with existing gem Oj which claims to be fastest JSON parser for Ruby
Benchmark results:
- Parsing 1.2 MB JSON file
Check benchmark reference here
- Parsing local JSON
Check benchmark reference here
Clearly FastJsonparser outperforms both Oj and ruby’s built in JSON parser

Let’s use it in your Ruby / Ruby on Rails projects and let me know how it performs.
P.S — Thank you https://github.com/saka1 for initial code.
