LiveCode Forums.

I'm happy to announce that version 1.1.0 of the fastJSON library is now available. This version cleans up some of the commenting that I had in the code, plus adds in some nice improvements from "madpink" and "mwieder". You will also see the library is now LC8 friendly as a script only stack. I have also updated my silly little test stack to include the LC8 lib as part of it's testing.

My non-scientific tests show that fastJson is significantly faster encoding/decoding JSON data compared to the LC8 LCB library.

fastJson is completely open source and on github at https://github.com/bhall2001/fastjson. If you're working with REST APIs or JSON data give it a try.

Hi Bob!

Are you able to attribute the significant speed boost in the LC 8 Array To JSON with the complex JSON file to any changes that have been made to fastJson? Or is it a result of engine improvements in LC 8?

Cheers,
Ali
