Improve responsiveness with big JSON files

[bjesuiter]

I have fairly big Json Files with a lot of sensor measurement data , that i need to compare.

Unfortunately, the comparison blocks the main thread for so long, that chrome thinks, the website has crashed.

2 Solutions:

• Send the JSON content to a server for diffing - maybe not wanted due to privacy and cost issues
• Use a WebWorker - Makes Browser Client Multi-threaded Workloads possible and is supported by ALL major browsers now (even IE/ Edge!) - see https://caniuse.com/#search=webworker

With a WebWorker, you could even give some progress response. At least you can show, that the site is working, at best you could show a progress bar! 🥇

Thank you for the suggestion. I have looked into web workers, but I don't think they would offer much improvement on the overall performance and they would complicate the application.

JSONDiff is a browser based tool and all of the compare runs in the browser. The advantages are a very fast load time and a super fast compare for smaller documents. The disadvantage is that there's a size limit to the types of compare we can do.

The best solution for this is probably to create a NodeJS based version of this tool. That would make it possible to take advantage of a faster runtime environment and better threading support.

I don't have time for that project right now, but you're welcome to take a look.

Thanks, Zack
