Good job. Make it available in the VSC marketplace... and also other IDE marketplaces
It'll be handy there
Thanks@chilarai I’m planning to make it available on the VS Code marketplace soon.
@hemendra_khatik awesome
I liked the line number for errors feature. Generally it's quote or colony missing and when on line number, I can debug easily.
Thanks!@khushal_sharma3 .
Congrats on the launch! 🎉
Are you planning to add a feature for generating a JSON Schema from a JSON file, or creating a sample JSON based on an existing JSON Schema?
Thanks! @yokotoka That’s a great suggestion! will work on it.
Congrats on the launch!
How does the tool handle very large JSON files while maintaining the instant performance you mention?
Thanks !@sanskarix Using memoized components and non-blocking rendering, it stays smooth and responsive. It can handle upto 4 MB JSON payload easily.
@hemendra_khatik That's a smart approach. Thanks!
@sanskarix
For anything above 4 MB, you'll probably need a desktop app rather than browser tool.
Browser tools hit performance limits around that size. Desktop apps can use multi-threading and native parsing (simdjson, etc.) to handle GB-scale files.
@hemendra_khatik Nice work on the launch! The clean UI and TypeScript generation are 👌
(I built a desktop JSONL viewer for the > 100 MB use case if anyone needs that - different tool for different scale)
